Ultra-crispy roast potatoes with soft, tender, and creamy insides, compliment a turkey dinner perfectly.
Mashed potato may be the spud of choice in America for Thanksgiving, but turkey always makes my Irish taste buds long for roast potatoes.

Irish Side Dish for Sunday Roast
Today's post is dedicated to the spud and the cooking method of choice for Irish Sunday dinners.
I'll show you my little tricks of the kitchen trade, to ensure your roasties turn out perfectly crispy every time. And if you prefer a softer outer crust, we'll discover how to achieve this too.
Roast potatoes are served for Sunday dinner in Ireland and often accompany roast chicken, roast beef, Yorkshire pudding, and vegetable side dishes like mashed rutabaga, carrot and parsnip mash, or cauliflower cheese.
Ingredients for Irish Roast Potatoes
Here's a quick list of what you'll need. You'll find exact quantities in the recipe card at the bottom of this post.
- russet potatoes
- vegetable oil or goose fat
- salt
- pepper optional
I like to use russet potatoes rather than Yukon Golds. I find they roast better, yielding a crispier outer layer with a floury centre.
Directions for Irish Style Roast Potatoes
Here you'll find my step-by-step tutorial for making the best roast potatoes with a crispy exterior and fluffy interior. This is one of my favorite potato recipes of all.
1. Oven Temperature
Pre-heat your oven to 400 degrees Fahrenheit. A very hot oven is needed to create that golden outer crust.
Many people roast potatoes by tossing them into the pan alongside their meat. This way the potatoes will soften and cook, but will never develop a tantalizing, golden appeal. The problem is with the oven temperature. Meat is usually cooked at temperatures between 300 degrees and 350 degrees. Fine for meat, but much too low for crisping.
In addition, the steam from the meat cooks the potatoes, so it is impossible to create the dry heat required for lovely roasties. The solution is two ovens, but if like me you only have one, just cook the meat first and then let it sit while the potatoes do their thing.
2. Potato Size
The next big decision is choosing your potatoes. I like russet potatoes, since they cook up a little "flourier" on the inside, and crisp up nicely on the outside. If you prefer a softer roastie then pick Yukon Gold potatoes.
Fingerling potatoes work fine too, but they can be roasted in their skins. No need to peel them since their skins are so thin.
Red potatoes can also be roasted using this technique.
You can roast potatoes of any size, but I like a medium potato. For faster cooking you can halve them, quarter them, or cut them into bite-size pieces. I prefer a substantial potato on my plate.
Picking similar size potatoes is very important if you plan on not cutting them.
3. Par-Boiling
Next peel the potatoes and place them in a large pot or saucepan.
Cover them with cold water, season them with salt and bring to a boil. Once boiling, reduce the heat and simmer for 5 minutes.
This par-boiling step is key to creating the crispy outer crust. So, even you are tempted, never skip it.
There is no need to fully boil the potatoes. You're simply starting the cooking process and softening the outside layer of the potato, so that you can rough them up and create nooks and crannies for the oil to help roast them. More on that in step 5.
4. Hot Oil
While the potatoes are boiling pour about ⅓ of a cup of oil into a roasting pan, then place it in the pre-heated oven.
You can use vegetable, canola, or peanut oil, and if you have duck or goose fat, even better.
I don't recommend olive oil as your first choice. It does not reach as high a temperature as the other oils, and high heat is key to good roast potatoes.
This hot oil step will seal the outer potato layer.
5. Roughing Up Those Spuds
While the oil is heating strain your potatoes. Feel free to use a colander, but I do it the Irish way, which includes a free steam facial. My mother always said:
"Why bother dirtying another thing, when you can strain away with the pot and its lid."
I just take a dish towel, spread it across the pot lid which is pulled away from the lip by a ¼ inch. Then holding on tightly to the handles I pour the water down the sink.
Be sure to keep that lid in place or you will end up with all your spuds in the bottom of the sink.
Now here comes another little secret for crisping your praties. Put the lid back on the pot and give them a good old shake. Roughing up the outer surface helps the hot oil stick to the surface and do its trick.
Take the lid off the pot and let the par-boiled potatoes sit for a few minutes to steam dry. Letting the excess steam escape is key to a good crispy roast potato.
If you strained them in a colander, just toss them around a bit, right in the colander.
6. Oil Basting
Next remove the pan of hot oil from the oven and add the potatoes. You should hear a little sizzle.
Turn them around in the oil to fully coat all the surface area of the potatoes.
I use a fairly big roasting pan. You need to space the potatoes apart so they are not touching. If you overcrowd the pan the potatoes will steam cook rather than roast, as their inner juices vaporize in the hot oven.
Feel free to season them with salt and pepper at this stage. I don't bother since I already added some to the water for par-boiling, and I like to keep sodium in our diet as low as possible.
If you wish to add some herbs or garlic powder, then this is the point in the cooking process where the flavoring ingredients can be added. My recipe today is for basic, plain roast potatoes with no added herbs or spices.
Pop them in the oven. After 15 minutes, take them out and give them a turn. Use a metal spoon to pour the hot oil over them. See how they are turning brown in this picture.
I turn them again in another 15 minutes.
7. Cooking Time
After 45 to 60 minutes you should have delicious, crispy spuds. Watch them closely towards the end so they do not burn.
I included a 15-minute window for final cooking time. How long is dependent upon the size of your potatoes. Bite size roasties may cook in less than 30 minutes.
And so, there ya go. If you follow these steps you will produce perfect, traditional Irish or English roasties every time.
My cooking method is for a standard plain roast potato, but the sky is the limit on different seasonings you can add.
Garlic, onion powder, paprika, thyme, rosemary all add an extra depth of flavor. Just sprinkle the seasonings of your choice on your potatoes when they are in the roasting pan waiting to hit that hot oven.
Happy potato roasting to all!

I wouldn't disagree with any of that. They should come out grand and crispy.
Do you really count temp in F. I'd say there isn't anyone under 70 that can convert since the lads on the telly went C for the weather round about 1970.
Irish American Mom
Vince - Our weather forecast is still reported in Fahrenheit over here. All ovens are still old school and there is no such thing as a Gas Mark for a cooker. My gas oven has a Fahrenheit temperature gauge. I have grown so accustomed to it I get all confused when I am cooking at home in Ireland. I actually have to google conversion tables.
Have a lovely weekend.
Mairead
Marilyn
I finally had the chance (and time) to make these! They are divine! My husband and son both asked when I was going to make them again! Thanks so much for sharing the recipe. I'll definitely be trying some of your other recipes!
Irish American Mom
Hi Marilyn - thank you so much for stopping by to let us know your family give these roasties their seal of approval. Roast potatoes are part of my Irish childhood - we had them nearly every Sunday for dinner. I hope you'll enjoy some of my other recipes.
All the best,
Mairéad

You should have titled this post: A Service To Mankind- My Roast Potatoes Recipe!
My husband does similar roast potatoes but not exactly like yours...we will try it your way and let you know. (My life is so hard, trying out a new way to roast a potato!) xx
Irish American Mom
Roast potatoes are just so good for Sunday dinner. We love them in our house too. Have a great weekend.
Andrea
Oh my, do these potatoes look fantastic! I can't wait to make these for my family. They are a perfect side dish.
Irish American Mom
Hi Andrea - These potatoes are a very popular side dish in Ireland, especially for serving with a roast Sunday dinner.
All the best,
Mairéad
Aimee
These sound so good! I've got a jar of duck fat in my fridge that needs using...we'll have to try these!
Irish American Mom
Aimee - Duck fat will make these potatoes so crispy and delicious. Enjoy! My mouth is watering thinking about them.
Aimee
These were SO delicious Mairead!! I had mixed results with the mashed turnips and rutabagas, but everyone loved these! And the duck fat made them smell (and taste!) so delicious! We're already planning to make them again next week!
Irish American Mom
Aimee - So glad you liked these roast potatoes. I prefer them to mashed any day, especially with any kind of roast meat.
I thought you might get mixed reviews on turnips and rutabagas. They are an acquired taste, and I had plenty practice eating them as a kid in Ireland. They were a staple on our dinner menu.
Take care,
Mairéad
Aimee
I think I would prefer them to mashed as well! We have successfully tried our kids on many different foods and have gotten so used to them eating things such as liver, kraut, etc that I guess I didn't think a turnip or rutabaga would cause that much pause. 🙂 I should have known though, since I've made caramelized turnips a few times and they've never been too pleased to see them on their plates. Hopefully soon we'll be able to add turnips and rutabagas to the list of foods our kids eat without thinking twice!
Irish American Mom
Aimee - I hated parsnips as a kid. My mom used to mash them up with carrots to try to get me to eat them. It took over twenty years before she finally succeeded. I hope you get your boys to like rutabagas much sooner than that.
Mairéad
Grammy
Oh YUM! I'll be making these this week!
Irish American Mom
They really are delicious Grammy.
Mairead
Thank you so much for posting this recipe. I made them this evening, carefully following all your instructions and they turned out perfect. Will be doing them a lot more often now!
Irish American Mom
Mairead - You can't beat crispy roast potatoes with a Sunday roast, and once you know the little tricks to ensuring that crispy outside, they really are pretty simple to cook. Glad you enjoyed them.
Mairéad
Maureen O' Hanlon
Oh Mairead your roast potatoes are fab, mine are never that great, its hit and miss with me, my mother used to make beautiful ones in the bastibal, i think i know now whats wrong, i put them in with the meat and i dont pre boil them either, im going to do them your way next time, you are a wonderful cook, i love the way you show every step, do you sell any cook books id buy one i love your recipies, and i love to see your lovely little hands on the pictures.i do be looking at them in awe and thinking what a wonderful pair of hands you have. 🙂
Have a smily day Maureen
Irish American Mom
Maureen - Your roast potatoes are probably steaming too much when they are cooked alongside the meat. I can only imagine how wonderful roast potatoes must have been cooked in the bastible. So glad you like my recipes. I would love to have a cookbook someday. I need to start planning what recipes to include. It's lovely to hear feedback from readers, since it let's me know what type of recipes people enjoy most. Sometimes it is the simplest recipes that are most popular.
Have a lovely day too.
Mairéad
Maureen O' Hanlon
Yes Mairead the roast pototoes done in the bastible were lovely done in goose fat , it was always a goose that time for christmas in the 50s and 60s never a turkey, my Mother used to clean out and pluck the geese for a farming family and i remember as a small child looking on and there would be feathers flying everywhere and she would always keep the wings and use as a little brush for picking up dust and cleaning, if my children saw a wing of a goose in our house they would be gone, as a small child I also remember red berry holly hanging over every picture and a big red candle on the window and I remember making the decorations out of beautiful crepe paper all different colours, im rambling now, ha.
Take care Maureen
I would love if you made a cook book and use all of your recipies they are all lovely.
Irish American Mom
Maureen - I love your stories. Thanks so much for taking the time to comment and share your lovely view of the world and memories of your Irish childhood.
All the best,
Mairéad
Barbara
I was wondering why you peel the potatoes. I have been taught that there are a lot of nutrients in the skins. I am just curious. These potatoes sound great. I live alone so I would only do a few potatoes at a time. Thanks for the recipe!
Irish American Mom
Barbara - I too have heard potato skins are very nutritious. I peeled these potatoes to cook them in the traditional way I was taught by my mother. If you want to try cooking them with the skins on, make sure you cut the potatoes, so allow steam escape as they cook. If you leave them whole with skins on, the outer layer will get very wrinkled and the inner flesh will pull away from the skin. You might end up with a baked potato rather than a roastie. I hope you enjoy these.
All the best,
Mairéad
Michael Heenan
These were marvelous tonight! Thank you! They accompanied the mashed rutabegas, which we also owe to you! Thank you so much for these helpfuland easy-to-follow recipes! We've done the sausage rolls and Scotch eggs and plan the Guinness beef stew for the weekend... You've become a part of our lives. Now, if only you could help with "veg roll," which seems to be an exclusively northern item. I smuggled the spices and rusk back from Fermanagh, but can't seem to get the proprtions rigth. Thank you again for a week's worth of satisfying meals that have transoirted me back to my childhood.
Irish American Mom
Michael - Thanks so much for your kind words about my recipes. So glad your family gives Irish cooking their seal of approval. I've never heard of "veg rolls" before, but I'll have to check with my husband's family in Donegal. I do make a vegetable type croquette that I call rissoles. They may be similar. I'll make some rissoles someday in the future to feature on my blog.
Best wishes,
Mairéad

Jane
Your potatoes look delicious and I plan on making them soon. Do you ever save the potato water for bread? I think it adds to the flavor and texture and helps with the rise. Thanks again for another mouthwatering recipe.
Irish American Mom
Hi Jane - I use potato water when I'm making a potato bread. Here's the link for that recipe ...
https://www.irishamericanmom.com/2013/07/16/potato-bread-yeast-recipe/
I have never reserved it to use for regular breads, but it sounds like a great idea. Thanks for the baking tip.
Hope you will enjoy these roast potatoes. I love them for special dinners especially to compliment a good roast beef.
All the best,
Mairéad
Alan Ellaway
Hi, I've never found a potato quite like the English potatoes to Roast the same way. The finnish just isn't the same. For Christmas dinner, I roast them with parsnips in a 50/50 mix of Butter(Irish of course!) and olive oil. Good but not quite the way I grew up on!
And while discussing potatoes, OOOHHH for a plate of delectable, delicious, decadent Jersey Royals, swimming in butter( Breast stroke, crawl backstroke-whatever!) with mint pas... Heaven!
Christy
Oh. My. Gosh. DELICIOUS!
Irish American Mom
Hi Christy - There's nothing as nice on a Sunday afternoon as a crispy roast spud for dinner.
All the best,
Mairéad
Serena
I am so excited to make these, but I have one question. When visiting Dublin, I had these same potatoes, and I can't find the name of the pub, to find out what the sauce was that was served with them- can you help? It was a white, garlicky, cream sauce, and it was amazing. There may have been some other herb flavors along with the sauce as well, but I think that was just some garnishing and seasoning on the potatoes themselves. I have been trying to recreate that dish with no luck. Thanks!!!
Irish American Mom
Hi Serena - My guess, and this is a complete guess, is that you had a garlic aioli sauce, or a garlic mayonnaise. Here's my recipe ...
Garlic Aioli Sauce ...
2 egg yolks
4 cloves of garlic finely grated
2 teaspoons of dijon mustard
pinch of salt
1 tablespoon of white wine vinegar
1 cup of olive oil
Put the egg yolks in a bowl and beat with a hand held electric mixer. Add the garlic, mustard, vinegar and salt and mix well with the beater. The next step is key. Add the oil drop by drop, whisking well in between. Keep adding the oil slowly and the sauce should start to thicken. After adding at least one third of the oil, you can start adding it in a very slow stream, whisking constantly.
You can add chopped parsley or herbs at the end. This stores well in the fridge for a few days if kept tightly covered. It may separate slightly and needs to be stirred or whisked before using.
I hope this helps and fingers crossed this sauce is something like the perfect sauce you found in Dublin.
All the best,
Mairéad
Lynnpo
Perfect. I was looking for this exact recipe..... if you've never tried this way you must! Thx for posting!
Irish American Mom
Hi Lynn - I hope your roast potatoes are a great success. Enjoy!
Mairéad
🙂 🙂 🙂
Lorna
Greetings from Dublin from a fellow fan of the roast potato!
Can I just add in if the potatoes are stuck to bottom of the dish when you are turning them over to leave them a while longer and try again. They will release from the dish easily when the outside of the potato has crisped up enough.
Roast carrots and parsnips together are fab too and taste divine when maple syrup is added to the roasting dish. Nigella Lawson has a recipe.
Lorna C
Irish American Mom
Hi Lorna - Lovely to hear from another roast potato fan. And thanks so much for your great tip for releasing potatoes fro the bottom of the roasting pan. It's such a disappointment when a whole side of a roast potato sticks and comes apart from the spud.
I love roast carrots and parsnips too. I've made them with a honey glaze but never tried maple syrup. I'll have to check out Nigella Lawson's recipe.
All the best,
Mairéad
Another Mairead
Thank you so much for sharing this; we just tried these tonight with a spinach salad and some pan-fried steaks, and are now converted to roasted potatoes. I don't know how the potato inside that oil-formed crust becomes so tender, fluffy, and delicious, so rather than study chemistry, I am putting it down to magic.
Thanks again! Looking forward to trying other recipes here.
Irish American Mom
Hi Mairead - You can't beat a little bit of potato magic and roast potatoes definitely taste like magic to me.
Thanks so much for trying out my recipe and for giving it your seal of approval.
Best wishes,
Mairéad
Alan Ellaway
I often toss the par boiled potatoes in spoon or so of plain flour,(it adds to the crunchiness, a sprinkling of rosemary, and add the heated oil to the potatoes in the saucepan to toss them and make sure they get a good covering. Easier than trying to turn them all in the hot oil in the hot pan.
Irish American Mom
Hi Alan - Great tips for making roast potatoes even crunchier and more flavorful. Thanks so much for stopping by.
Best wishes,
Mairéad
Karen Miller
Thank you, thank you, thank you! My Irish Nana (great grandmother) used to make her potatoes just like this when I was a young girl. I have missed them so, and never knew how she accomplished this. I'll be making these tonight along with a roast!
Irish American Mom
Hi Karen - I'm thrilled this recipe solved your roast potato recipe quest. There's nothing like a roast potato with a lovely Sunday roast. Happy cooking and I hope that roast was extra special tonight with your Irish spuds.
All the best,
Mairéad ☘
Debbie W
Made these tonight with Pinot Noir Chicken with Mushrooms. Potatoes were a hit. Will definitely make these again, especially with a roast, like a standing rib.
Irish American Mom
Hi Debbie - It's great to hear these potatoes went down well in your house. They're a great side dish and are fantastic with a roast. Thanks so much for adding your feedback here. I really appreciate it.
All the best,

Mary Sullivan
Mairead, thank you for sharing your wonderful recipes. I just finished a bowl of potato and leek soup for lunch. Divine! I've made a lot of your recipes and all are a hit. We will be having the roasted potatoes tomorrow. I can see the step my husband has been leaving out in his quest to make them like his Irish mother. The hot oil in the pan. Since you like the crock pot I will tell you the EASIEST recipe to make in it. I always make it for parties and serve with little rolls. Just take an inexpensive roast- the cheapest and put it in the crock pot with one envelope of dry Good Seasons Italian dressing mix. That's it. Nothing else. It will make it's own liquid. Cook it for six or seven hours until it falls apart. I just stir it with a fork and it absorbs all of the liquid.
Irish American Mom
Hi Mary - It's lovely to hear my recipes have been a success for you. Thanks so much for trying them out. I do LOVE my crockpot and your roast recipe sounds so easy. I've never tried cooking a roast in its own liquid before, but I'll have to try it out. Thanks so much for sharing your cooking tips.
All the best,

What a delicious Irish potatoes recipe! I made the potatoes and a crisp green salad, and my husband grilled the steak. These roasted potatoes were a huge hit. So delicious!
Irish American Mom

All the best,
Mairéad
Kathleen
Can you make these earlier in the day and then reheat them when your meat is done?
Irish American Mom
Hi Kathleen - They won't taste as good as when you first make them. The crispy outer skins tend to shrivel when reheated and they just aren't as tasty. Now, when I have leftovers I do reheat them. They taste best when reheated in an air fryer, but they won't be as delicious as when they are first roasted.
All the best, and happy Christmas.
Mairéad
Susan
Great! Really worked out!

Hi Susan - That's brilliant to hear. Thanks for trying out my recipe.

I love this recipe! So far have o ly used canola oil but want to try with beef tallow next. Would that work?
