In the mood for some really crispy oven roasted potatoes? These are hands down the easiest and best roast potato recipe with only two ingredients and are made without baking powder. The best side dish for roasted turkey or juicy beef tenderloin.

My mother-in-law Katie was a pretty functional but good cook. She cooked what worked and did it well. Case in point: these crunchy crispy oven roasted potatoes. They can be on the table in under 40 minutes and are the perfect side dish for beef tenderloin sliders, some juicy Foolproof Chicken or your favorite barbecue dish.
So—let's get to cooking so that these creamy roasted potatoes can get on your table and in your belly.
Two Ingredient Roasted Potatoes
I mentioned earlier that you'll only need two ingredients (not counting salt and pepper, of course) to make these oven roasted potatoes. And neither one of those ingredients is baking soda or oil each of which some people say is the key to the best oven roasted potato.
Me? Not so much.
There are recipes that make roasted potatoes with baking soda and there are some that make them using oil. We are going straight for the good stuff.
Butter.
That's right. The two ingredients you need are:
- potatoes (and we'll talk what kind below)
- unsalted butter. Since you're going to be seasoning the butter anyway, unsalted butter gives you more control over the results. I will admit Katie used margarine in a lot of recipes but this one is strictly butter. If margarine is all you have, be careful because it typically contains water and you might not get the even color and crispness that you would from butter.
Three key tips for the best roasted potatoes
Potatoes were made for roasting. There are three things necessary to make super crispy roasted potatoes.
- Heat - No one likes a raw potato so whether they're boiled, baked, fried or roasted, potatoes need heat.
- Fat - Necessary for roasted potatoes to be their best crispy selves.
- Seasoning - Because potatoes are bland in flavor, they are super versatile taking on the flavor of whatever they're seasoned with.
Best potato varieties for roasting
Some potatoes are better than other for roasting. Some favorites are:
- Idaho Russet potatoes - the cut side browns beautifully to a crispy golden crunch with a fluffy interior.
- New potatoes (large and small) - Typically red, these babies come in different sizes with the smallest (sometimes the size of your thumbnail) being Type C and working their way up to the more traditional, larger Type A's.
- Yukon gold - the flesh has a slight buttery flavor which no one is evah going to complain about.
- Sweet potatoes - You wouldn't think it possible but when sweet potatoes are roasted, they get even sweeter. Sweet.
Step by step process
Gather these ingredients to make crispy oven roasted potatoes:
- a half-sheet pan with sides, approximately 12 x 17
- one stick of butter
- one potato per person you plan to serve
- salt and pepper
- You'll place the baking sheet with a stick of butter into a preheated oven and let it melt.
- Sprinkle your seasoning of choice on top of the melted butter (I am using just salt and pepper) and then place your halved raw potatoes face down into the butter bath brushing the tops with the butter and seasoning mixture.
- Roast the potatoes face down for about 35 minutes and flip the potatoes to reveal the brown and toasty ah-ma-zing glory.
Success!

Serving Suggestions
As a big blue cheese fan, I highly recommend serving some dipping sauces with these crispy potatoes. Two with so much flavor are:
Creamy Mascarpone Ranch Dressing
Make ahead
Because this is such an easy recipe, I wouldn't recommend making them ahead. You're not really saving any time because you have to reheat the potatoes anyway which takes about 15 minutes.
Storing
Store leftovers in a sealed container or bag. Use within 3 days.
Reheating
To reheat any leftovers (if there are any), brush a baking sheet with some butter (or just take the end of a stick of butter and make a few quick swashes across the pan). Put the leftover potatoes cut side down and reheat for about 10 minutes in a preheated 350˚ oven.

How much butter would I use if I don't have stick butter
Hi Samantha! 1 stick of butter is equivalent to 1/2 cup of butter or 113 grams. Hope that helps and thanks for taking the time to ask!
Hi. I'm really looking forward to trying the recipe however my phone has an Amazon ad ( that will not go away) covering step one of the cooking instructions. Can you please tell what temperature, etc are in step one?
Hi Jan! That is really annoying, I must say and I'll address it with my ad company...I appreciate your reaching out! Here are the steps of the recipe...hope it helps and thanks again!😀

Hi Lori,
I came across your recipe and had to try it. I modified it by using bacon grease instead of butter as that is what I rub on my potatoes before baking them. I also added dried basil, garlic salt and a South African smoke seasoning I buy at Trader Joe's. When they were done being cooked I used a little sour cream that I spread atop and spread a little sun dried tomato atop as well. They were delicious! Thank you for sharing your quick and easy preparation of this marvelous recipe! I will be making these again. Now if I only knew how to include a photo showing the finished product, lol.
Hi Kate! Thanks so much for your kind words! I really appreciate your taking the time to comment 🤗. And your variation with the South African smoke seasoning and sun dried tomatoes sounds amazing - what a flavor bomb! I'll have to pick up some of that the next time I'm at TJ's. It sounds like something I definitely should have in my spice drawer. If you're on Instagram, feel free to tag @josieandnina if you share a photo...I'm sure I'd be drooling! Happy holidays to you and yours!
Excellent!!!! Truly crispy and perfect!! We loved these for dinner. I used red potatoes and they were great. They will definitely be a staple side dish from now on.
Yay Susie! My mother-in-law would love hearing how much you enjoyed them! Thank you!!🤗
Even better with fresh grated parmesan cheese in the pan & then place the cut side of the potato on the cheese. Turns out nice & crispy!
Love that idea! I'm always in favor of more cheese! 🤗
These look delicious Lori, and who doesn't love a crispy potato!?
Exactly!! Especially one with only two ingredients 💃🏻 Thanks Kendell!!
