These potatoes combine the fluffy interior and crispy exterior of the best roasted potatoes with the crunchy cheese crust of Detroit-style pizza. The initial boil with aromatics adds herbal flavor to the potatoes, without the potential of burned herbs in the final roast, while baking soda in the water helps soften the surface of the potato, releasing starch. This starch combines with Parmesan and melted butter to form a flavorful slurry that crisps up and coats each potato chunk in a cheesy shell.

Extra-Crispy Parmesan-Crusted Roasted Potatoes Recipe (2)

Preparation

Make the recipe with us

  1. Step

    1

    Adjust oven rack to center position and heat to 425 degrees, or 400 degrees if using convection. (Convection is recommended, if available.) Combine potato chunks, 2 quarts water, baking soda and salt in a large saucepan.

  2. Cut a 10-by-10-inch square out of cheesecloth and place bay leaves, peppercorns, garlic cloves and herb sprigs in the center. Gather up the corners of the cloth into a pouch, and tie off with butcher's twine. Add bundle to the pot with potatoes, and set over high heat. Bring to a boil, and cook until you can poke a knife into a larger chunk of potato without any resistance, about 10 minutes after the water comes to a boil.

  3. Step

    3

    Drain potatoes in a colander and discard aromatic bundle. Line a 13-by-18-inch rimmed aluminum baking sheet with parchment paper.

  4. Step

    4

    Transfer potatoes to a large bowl. Add melted butter and Parmesan. Season lightly with salt and pepper. Toss and fold with a rubber spatula until Parmesan, butter and starch form a slurry over the surface of the potatoes, about 30 seconds. Transfer potatoes to the prepared baking sheet and spread out so they are mostly separated from one another. (At this point, they can be allowed to cool, then transferred to a sealed container and stored in the refrigerator until ready to roast.)

  5. Step

    5

    Transfer baking sheet to oven and roast potatoes until pale golden brown and sizzling on the bottom, about 20 minutes. Flip potatoes using a thin metal spatula and continue roasting until crisp and blond-gold on most sides, about 15 to 20 minutes longer. (Check frequently toward the end, and don't allow the potatoes to cook beyond a deep gold, or they will turn bitter.)

  6. Step

    6

    Remove potatoes from oven and allow to cool for 5 minutes on the pan before transferring to a serving platter.

Learned this from my Italian Mother. Just bring the potatoes to a boil, then take them off the heat and drain. They'll continue to cook off the heat. If you boil them too long, they'll get mushy. Let them cool. Then toss them with olive oil (not butter) and grated Romano cheese (prefer it to Parmesan). I also add some sprigs of rosemary. And big cloves of garlic. No need to peel them. Roast them in the oven as described in the recipe.

James L

Having made both previous recipes (boil in vinegar, boil in baking soda), I don't bother with trying to make the slurry with a spatula or slotted metal spoon. Potatoes, fat of choice (oil or now butter here), seasoning, go in a mixing bowl, I cover it with something hard like a lid/plate, and a shake it up vigorously. The potatoes mash against each other and the bowl and gets properly covered by the oil/potato/seasoning slurry. Faster, easier, more even coverage.

Susan B. A.

Kenji created this recipe a few years ago (sans spices/cheese) and it's the only one I make.However, I'm lazy & now have some shortcuts. Preheat oven with baking pan IN. Boil potatoes (Yukon for me) w/salt + spices if using; drain.Put potatoes back in pot. Cover & Shake hard 3 times up and down! Stir in duck fat, more salt, parm if using. Pour onto hot pan (the sizzle!) & bake. Crunchy outside, creamy inside. Divine.

Michael

Dear Honored Chef and Esteemed Fellow Readers---Who in their right mind discards garlic before roasting potatoes??? Really??!!And would it not improve the dish to have a few thyme or rosemary leaves speckling the coating (spice bundles are froufrou to me), not to mention a dash of paprika?Happy Cooking!Yours in gustatory pleasure and partial jest (I take garlic very seriously),Michael

rsb56

Oh my gosh, YES, it MUST be Turkish bay leaves. I wouldn't think of serving my guests this recipe any other way and run the risk of one of them saying, "This wasn't seasoned with TURKISH bay leaves, was it."The disapproval would kill me.

Laura Perry

Cheesecloth is a nuisance. I use fine-mesh bags from https://washableproducebags.com/ instead. They’re bags with drawstring closures, and they’re completely washable and reusable. Drain yoghurt, homemade butter; screen out lumps in gravy or custards; or, as here, make it easy to fish out aromatics from a broth.

LivFranca

Love this; so easy and scrumptious. I do save the boiling water, full of its lovely herbal flavors, for amazing yummy soups. I’ve learned to never throw good things out...

M

Is there a reason to use the cheesecloth rather than just put the flavorings in the water and discard them at the end?

TommyC

I stared for about 60 seconds at "preferably Turkish" on the ingredient list under bay leaves. I pondered, dare I precede using Pacific NW bay leaves? I was so unaware about bay leaf terroir. I decided to live on the edge and make the dish. And while guests feigned delight, I still wondered if they were just being polite, sensing I had used backyard bay leaves.

Dan J

The best way to get a crispy coating and fluffy interior is to return the potatoes to the hot saucepan immediately after draining and really shake the pan around a few times. This roughens the surface and creates a wonderfully crispy exterior.

Prairiedogg

cooked with small yukon gold taters. boiled in some leftover chicken broth. quartered, but didn't peel. didn't bother with the cheesecloth, just threw the herbs and spices in the cooking water. pretty tasty. will make again. sorry, but my mom was Norwegian.

stu

I followed the recipe, except i made the mistake of not reading it thru. So, i used a cast iron roasting dish to cook the spuds. I got a great result. Cast iron hold the heat so the bottoms were real crisp. They were a little crowded so i hit it with the broiler. It all worked really well. I doubt i’d ever do it differently. Very nice recipe.

Corinne

So delicious! A friend asked me to make these for her and I did not hesitate. I followed the recipe just about to the letter, except I found no need for the cheesecloth bag. I just threw everything in the water and removed the potatoes with just bits of the peppercorns and rosemary still stuck to them. Nothing wrong with that. These were SO VERY GOOD. I will definitely make them again.

Andrea from SoCal

Delicious! Delicious! I'd like to share two observations: don't make the mistake I did, by using foil on my pan rather than parchment paper. It made for a messy messy attempt to dislodge those delicious potatoes. And, secondly: my family likes a crispy potato. So, after it was all done baking, I put in under the broiler for about 60-75 seconds. YUMMY! Thanks Kenji for yet another delicious recipe.

James L

@Peggy Herron. The pic from this article isn't the best at showing it's crispyness, the pic from the previous recipe shows it better. https://www.seriouseats.com/recipes/2016/12/the-best-roast-potatoes-ever-recipe.htmlIt's not that much more work. You boil the chunkier potato like most other roast potato recipe. Drain, add oil/seasoning, fluff up the outside in a bowl, bake. The mashed potato outside turns into a batter like crispy crust.

The Big Woo

Works great with gruyere and melted butter too!

JackandRosiesma

Has anyone tried the oven stage in an air fryer with a raiser function? If so, which function, what temp and how long? Thank you!

DeAnn Trimarchi

I did like it, but for me, I'd add more spices than just salt, pepper, butter and cheese when roasting. I enjoyed using cheese cloth for the first time. I'd make this again with a couple of adjustments to taste! Thanks for sharing this recipe!

Teresa

Made as directed. Perfectly crunchy. Excellent flavor. Added to my favorites.

Tish

I love these potatoes. So much. I had no cheesecloth once so just put everything in the water loose. Much of the herbs and peppercorns stick to the potatoes, but it turns out I like it that way. So now this is how I always make them and they are still my fave (though I use more butter/parmesan than the recipe calls for… because who can have too much of it? Not me!)

maxgcan

In the video Kenji Lopez-Alt says that he measured out the water because he used a measured amount of baking soda. The recipe calls for 1/2 tsp of baking soda. But how much water? Did I miss it? Help!

Rose K.

As much as I love potatoes, I ain't making ANY potato recipe that requires six steps.

Jaclyn

I never review recipes but my family and I subbed these the best potatoes they’ve ever eaten.

Jason

I'd suggest two changes: While potatoes are boiling, place a large sheet pan in the oven with 3T duck or goose fat. Then swap out Step 4 for this step: Put potatoes back in pot and shake vigorously. Then transfer to pre-heated and fat-coated sheet pan.

Betty P

Has anyone tried this recipe with non-russet potatoes? I would like to make it but, as usual, have only Yukon Golds on hand.

Teresa

There was a post from 4 years ago that said they used Yukon Gold potatoes, and they turned out perfectly.

Karen Oliver

Doesn’t baking soda leach out all the nutrients?

sweet potatoes?

Will this work with sweet potatoes?

Shirley Ricci

I’m from the north of England and this recipe is far easier than mine!!!

Brandon Ferguson

I don’t have a comment about the recipe. I just wanted to say - Kenji, you look great!!

Tom J

What is this obsession with using foil or parchment paper? This recipe work perfectly baked directly on the base of a greased baking tray.

Extra-Crispy Parmesan-Crusted Roasted Potatoes Recipe (2024)

FAQs

Why won't my roast potatoes stay crispy? ›

You might not be using enough oil. If you're not using enough oil to coat the potato, it won't get crispy as it bakes. You might be using the wrong type of potato. Potatoes with a high starch content, such as Russet potatoes, are better for baking because they become fluffy and crispy when cooked.

How do you keep crispy potatoes crispy? ›

Keep potatoes crisp in a warm oven if you're serving them in 1-2 hours. If there is a slight wait before everyone eats, don't cover the crispy potatoes—this traps steam which will make the potatoes soggy. Just keep them in the oven, but turn the temperature to the lowest setting.

How do you're crisp roasted potatoes? ›

Heat your oven to 400 degrees, spread potatoes on a sheet pan and cover them in tin foil. Re-roast them until they're warm all the way through, about 10-15 minutes. Remove the cover for another five to add crispiness.

Why are my potatoes soggy and not crispy? ›

Roasted potatoes can become soggy if the water content in the potato isn't fully cooked. Different potatoes have different water content percentages. Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy.

What is the best oil to use for roast potatoes? ›

Neutral, low-cost oil such as vegetable oil, canola oil, safflower oil, peanut oil, corn oil, coconut oil, avocado oil, etc., work well for roasting. These oils have a high smoke point, allowing the potatoes to get very hot to achieve maximum crispiness.

What makes potatoes crunchy? ›

Parboiling the potatoes in alkaline water breaks down their surfaces, creating tons of starchy slurry for added surface area and crunch. Offering you the choice of oil, duck fat, goose fat, or beef fat means you can get whichever flavor you want.

Should I dry potatoes before roasting? ›

To have a truly marvellous roast potato, one must simply let the potato dry completely after parboiling, before roasting in extremely hot fat. If you have two ovens you can cook them separately to your roast at a different temperature.

Does cornstarch help with crispy? ›

Coating small pieces of chopped meat, fish, shrimp—or even cauliflower—that will be sautéed or stir-fried in some straight-up cornstarch, gives you a crispy coating after after a super short time sizzling in that oil.

Should you boil potatoes before roasting them? ›

Do I have to boil potatoes before roasting? Not necessary but this can help get the perfect consistency and crispiness. Make sure you boil them but leave them a bit al dente and they will crisp up perfectly in the oven.

Why do you soak potatoes before roasting? ›

Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.

Why does vinegar make potatoes crispy? ›

The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying. Additionally, the vinegar can contribute to a golden-brown color on the exterior of the fries.

Does tin foil make potatoes crispy? ›

Don't wrap your potatoes in foil

"I see a lot of people using foil to wrap their potatoes in but this is a big no-no and causes soggy skins!" he says. Foil holds in moisture and steams the potatoes, resulting in a "boiled" taste and texture. Plus, without the use of foil, the skin will get extra crispy and flavorful.

Can you put too much oil in roast potatoes? ›

'Though we all love a crispy roast potato, it can be really easy to mess them up,' said Jeff. 'If you drown them in too much oil, they'll burn on the outside and be undercooked on the inside. ' He recommends par-boiling your spuds then fluffing them up before roasting for best results.

Does soaking potatoes in water make them crispier? ›

If you want to prepare your potatoes later after you have cut them soaking them in cold water will keep them from turning brown. Also, if you are going to fry them they will turn out crispier. Soaking them helps to remove the starch.

Why do you put cornstarch on potatoes? ›

The key to the crispy, crunchy exterior is in the method for their recipe: shaking the boiled and drained potatoes roughly until the outsides break off and begin to form basically a “potato paste” on the outsides. For my recipe, I add potato flour and cornstarch to encourage an even crispier-crunchier crust.

Why are my roasted potatoes not getting soft? ›

To ensure that your potatoes become soft and tender, consider using the right type of potatoes, ensuring even and appropriately sized cuts, providing sufficient liquid, and avoiding overly long cooking times.

What happens if you roast potatoes too long? ›

Potatoes can become mushy and lose their shape if cooked for too long.

How do you keep roast potatoes crispy when transporting? ›

If it's going to be longer, allow them to cool below 200F, put in a large bowl and seal well with oven-safe plastic wrap. Again the temp keeps them from cooking, but you might lose a little crispness in the potato skin. But they will still be pretty crispy, hot, and delicious.

Why does soaking potatoes make them crispier? ›

These tips are completely doable, actually pretty much fail-proof. SOAK your potato chunks in cold water. This removes some of the starch and helps get them super duper crispy.
