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.

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?

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.

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.

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.

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.

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.

Ellen M.

Is there a good way to re-heat any leftovers for this? Of course they are best fresh, but I'm cooking for one and will not be able to eat the whole recipe.

Bob McK

Used pecorino cheese and fresh herbs from the garden. Turned out amazing.

Bev

These are amazing! I never have a cloth bag to tie up the herbs, but just toss into the pot…remove when ready to roast. Superb!

McWallop

If I had to roast at 450 instead of 400, how would the timing change, and is there anything else I should worry about? Trying to do it with a chicken recipe at the same time

SW

Can I sub any other kind of hard or semi-hard cheese I have lying around?

Cindy E

These were very good. But, I had to bake them about twice as long as the recipe called for. I do live at an elevation of about 6600 feet, but that doesn’t usually impact bake times. I used my oven’s convection feature and finally upped the temp to 425. That seemed to do the trick. Next time I’m going 425 convect the whole way.

Nancyh

My family loved these crispy potatoes. I'm going to double the recipe next time.

Irwin

Potatoes had a great taste and crunch

echertc

Mike made the night before I left for Florida..used unpeeled yellow and red potatoes…best potatos ever…needed salt because he forgot that…

Patricia

Easy, excellent, even without the Parm!

McWallop

Made them exactly as written, and they were phenomenal. Like crispy little popcorn taters! Haha, thank you Kenji!

Daniel K.

I forgot the baking soda, I used pecorino instead of parmesan, I didn't watch the video, but knowing that creating a rough surface from other recipes I've seen- I shook the potatoes in a colander- and it all turned out great! Tasty with a grilled tenderloin on a warm February night in Minneapolis.

Chef Carlos

Excellent and fun to watch kanjis video. Takeaways: chop potatoes 1” square for more surface area, add salt. Then perfecto!

Joan T

Do you keep skins on or off?

So good!!

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.

Should you boil potatoes before roasting? ›

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.

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.

Why do my roast potatoes go soggy? ›

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.

Which oil is best 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 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.

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.

Why put flour on roast potatoes? ›

Roast for 1hr until golden and crisp, and don't forget to turn them occasionally to ensure they cook evenly. Here's a few tricks to try to make them even more delicious. Sprinkle your parboiled potatoes with flour. This gives potatoes extra crunch.

How does Gordon Ramsay make the best roast potatoes? ›

In a video online, Gordon explained: “For crispy roast potatoes, you can depend on them, my tip is to parboil them, leave them to steam dry, then sprinkle them with semolina or flour, and then give them a good roughing up.”

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.

What makes potatoes crunchy? ›

Baking Soda: Do not skip the step of boiling your potatoes with baking soda. Baking soda will help your potatoes get crispy in the oven. This is the trick! Thyme: I used fresh thyme for these crispy potatoes but you can also use dried thyme or swap out the thyme for a different herb like rosemary.

Does soaking potatoes in water make them more crispy? ›

Soaking the sliced potatoes in water helps to draw out some of the starch from the middle of the potato, resulting in a sturdier, crispier French fry.

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.

Why do my roast potatoes take so long to cook? ›

If you're cooking the potatoes after they've been in the fridge, the cooking time may be a little longer than normal as the potatoes will be cold. If you are cooking a whole roast dinner and are in and out of the oven you may find your roasties take a little longer.

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 the next day? ›

The day before (WITH part-baking)

Cover and place in the fridge overnight. To finish them off the following day, heat more oil in a tray and cook for about 15-30 minutes until golden and crispy (should be closer to 15 but sometimes this can take a while as the potatoes will be cold from the fridge).

Why does soaking potatoes make them crispier? ›

You soak them to remove excess starch. It helps them get crispier and prevents them from sticking together. You dry them off because water and hot oil don't mix.
