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. Step

    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.

Cooking Notes

Alan D.

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.

Imout

I make this tonight and they were wonderful. Didn’t have cheese cloth or fresh thyme. Used dried thyme, garlic, and had smoked peppercorns - just tossed them in the pot. I do have California bay leaves from a friends’ tree - and love the aroma and flavor. Will use them next time.

Jim Pickard

Wow! That looks amazing!Loved the video.

Tim H

Whoa loved this the first time but this time carefully timed 10 minutes after boiling — pan full of mush! Heading out for more potatoes and maybe the brief cooking method in notes

Gregory L.

Potatoes have always been the one thing I only eat when I'm out for a meal (nothing like a good pommes frites at the bistro or hash browns at brunch). But now, with this recipe, I've got my new go-to potato dish for home!--especially for when friends come by. My take: Do not skimp on the finishing rosemary! I sprinkled lots of it over the potatoes right when they came out of the oven, so they could take in the flavor while they rest on the pan. Thanks so much for this recipe.

gerry

soooo Good! I threw the herbs right into the pot with the taters. Added unpeeled garlic cloves to the baking pan. My family loved this.

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!

KHH

I used about half recipe--4 medium russet potatoes each cut into 6 pieces. Instant vortex plus. Air fried 400 degrees for 20 minutes directly on the grate. It worked even with the slurry and maybe over-cooked potatoes. Just enough room for a single layer. Tossed at 10 minutes and again when prompted by the fryer. Possible could have gone another few minutes, but they were crunchy, golden, and delicious.

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.

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

FAQs

Why won't my roast potatoes stay crispy? ›

Parboiling the potatoes is a good start, but if they're not getting crispy during roasting your temperature isn't high enough or there's too much moisture.

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 to re-crisp roasted potatoes? ›

Arrange cooked potatoes on a baking sheet in a single layer (if desired, line with parchment paper). Cover pan with aluminum foil and place in hot oven. Cook for 20 minutes, and then remove foil and let them go for another 5-10 minutes or until they are the crispy potatoes you are looking for.

Should you boil potatoes before roasting? ›

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.

What is the best oil for roast potatoes? ›

Roast potatoes verdict

Vegetable oil is the ideal choice for those who like a subtle, or blander flavour from their roast potatoes, because it cooks best at a medium heat and so the potatoes won't take on too much flavour from the oil. This also means the potatoes won't overpower other dishes.

What makes potatoes crunchy? ›

It's simple, and it produces amazing results. Boil chunks of potato until they're just tender, toss them none-too-gently with fat (ideally beef drippings) to rough up their surface, then roast them until they're crisp and crackling. The boiling and roughing-up steps are the real keys.

Why won't my potatoes get crispy in oil? ›

A: This sure sounds a lot like potatoes that have been stored too long, in too cold of an environment before cooking. When potatoes are held below 41°F for too long a period, the starches convert to sugar and it changes the cooking chemistry.

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.

Does cornstarch help with crispy? ›

Yes, cornstarch—that box in your pantry is the secret to a super-crispy exterior on veggies, from potatoes to cauliflower.

Why put flour on roast potatoes? ›

Sprinkle your parboiled potatoes with flour. This gives potatoes extra crunch. A tablespoon is all you need! Throw in some whole, unpeeled garlic cloves or a handful of herbs (thyme, sage or rosemary all work well) with the potatoes when adding them to the hot roasting tin.

Why are my roasted potatoes gummy? ›

Using Foil -

Foil traps the moisture in the potato causing the skin to be wet and the inside flavorless or gummy. Potatoes are made up of about 80% water, so sealing it up in foil does not allow enough water to escape, making it soggy.

What happens if you don't 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.

What does cornstarch do to potatoes? ›

When the corn starch comes into contact with the hot oil, it forms a barrier that traps moisture within the potato while also developing a crunchy crust. This results in fries that are both tender on the inside and crispy on the outside, mimicking the texture of fries you might find in restaurants.

Why are my roasted potatoes mushy? ›

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.

How do you keep roast potatoes from getting mushy? ›

Try placing oil in a spray bottle or using an aerosol to apply the oil to the potatoes. Lastly, ensure that the potatoes are dry before you add the oil. Excess moisture will increase the cooking time of potatoes and may result in soggy spuds.

What causes soggy roast potatoes? ›

Top Tip: Give each potato enough space to ensure it cooks evenly. Overcrowding the tray can cause the potatoes to steam rather than roast, resulting in a soft and soggy texture rather than crispy.

Why are my potatoes not getting soft in the oven? ›

Old Potatoes: Very old or stored potatoes can become starchy and may not soften as well during cooking. It's best to use fresh, firm potatoes. Acidic Ingredients: If your soup contained highly acidic ingredients (e.g., tomatoes), it could have affected the texture of the potatoes.
