Ingredients for america's test kitchen twice baked potatoes
Six simple ingredients create America's Test Kitchen's legendary crispy-topped, cheesy pull-apart potatoes.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Medium size, unpeeled for texture |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, full-fat preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for best creaminess |
| Cornmeal 🌽 | ¼ cup | Fine grind for crispy topping |
| Butter 🧈 | ½ cup | Unsalted, melted for topping |
| Milk 🥛 | ¼ cup | Warm for mixing with potatoes |
| Garlic Powder 🧄 | 1 tsp | For subtle flavor boost |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Chives 🌿 | 2 tbsp | Chopped, for garnish |
| Sour Cream 🥛 | ¼ cup | Optional for serving |
Russet potatoes are your best bet here—their fluffy texture holds up perfectly to twice-baking. Buy them fresh (look for firm, blemish-free skins) and store them in a cool, dark place until ready to use. For the cheddar, sharp cheddar from a block melts best—pre-shredded gets clumpy and lacks flavor. I grab mine from Whole Foods or the deli counter at Kroger; it makes all the difference. The cornmeal topping is non-negotiable for that crispy crust—don't substitute flour or breadcrumbs, no matter how tempted you are.
No sharp cheddar? Pepper jack or Gruyère works in a pinch, but the flavor profile changes. Heavy cream too expensive? Half-and-half or even whole milk will work, though the texture won't be as rich. Short on chives? Green onions or parsley are fine—just chop them finely. For the cornmeal topping, if you can't find fine grind, pulse regular cornmeal in a food processor for a smoother texture. And if you're prepping ahead, make the topping mix in advance—it keeps for days in an airtight container.
These reheat beautifully—just pop them in a 375°F oven for 15-20 minutes until crispy again. The leftovers actually taste better the second time around (seriously). For meal prep, portion into individual baking dishes so everyone gets their own perfect potato. Store any uneaten portions in the fridge for up to 4 days, or freeze for 2 months—just bake from frozen, adding 5-10 minutes to the reheating time. The secret to crispy reheats? Broil for 2-3 minutes at the end to restore that golden crust.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe because it’s literally one pan, one bowl, and done. The cornmeal crust forms right on the sheet pan—no rolling, no fuss—while the heavy cream and butter melt into that dreamy, gooey center. My lazy Sundays just got a whole lot easier.
- Cheddar Overload: That sharp cheddar isn’t just an afterthought—it’s the star. The first bake softens it just enough to stretch into creamy strands, while the second bake crisps it up edges. Honestly, I’ve tried fancier cheeses, but this? It’s the kind of salty, melty perfection that makes me skip dinner for leftovers.
- Game for Any Gathering: Need a side for a Super Bowl party? A picnic? A quiet Tuesday night? These potatoes handle it all. Double the batch, reheat them in the oven, and they’re still golden and crisp. My in-laws think I’m a genius when I bring them—no effort, all flavor.
- Budget-Friendly Luxury: Russets are cheap, butter makes everything better, and a block of cheddar lasts forever. The heavy cream feels indulgent, but it’s a small splurge for a dish that feeds four for under $10. Between us, this is how I trick myself into feeling fancy without breaking the bank.
Step-by-step instructions for america's Test Kitchen twice-baked potatoes
Here's the foolproof method for cheesy, pull-apart potatoes with a golden cornmeal crust.
Bake the Potatoes Until Fork-Tender
Preheat your oven to 425°F and position a rack in the center position. Scrub the 3 lb russet potatoes clean, then pierce each with a fork in several places. Place them on a baking sheet and bake for 45-50 minutes until completely tender when pierced with a knife.
Here's the thing—don't skip the piercing step. It prevents the potatoes from exploding in the oven. You'll know they're done when the knife slides in easily with no resistance. Let them cool for 10 minutes before handling—they'll be scalding hot right out of the oven.
Scoop and Mix the Potato Filling
Cut each potato in half lengthwise and use a spoon to scoop out the flesh, leaving about ¼-inch thick shells. Place the flesh in a large bowl and mash it with a potato masher or fork until smooth. The skins will crisp up nicely in the second baking, so don't worry about removing them completely.
Add the 1.5 cups sharp cheddar cheese, 0.5 cup heavy cream, 0.25 cup milk, 1 tsp garlic powder, 1.5 tsp salt, and 0.5 tsp black pepper to the mashed potatoes. Mix well until the cheese is fully melted and incorporated. I like to use a rubber spatula for this—it gets into all the crevices and makes mixing easier.
Assemble and Bake the First Time
Spoon the potato mixture back into the skins, pressing gently to fill them completely. Place the filled potatoes on a parchment-lined baking sheet. The skins should be touching each other—this helps them develop that crispy pull-apart texture.
Bake at 375°F for 25-30 minutes until the tops are lightly golden. Here's where the magic starts happening—the cheese will begin to bubble and the edges will get tender. Don't overbake yet—you want them to hold their shape for the second baking. Let them cool for 5 minutes before moving to the next step.
Create the Crispy Cornmeal Topping
While the potatoes are cooling, melt the 0.5 cup butter in a small saucepan over medium heat. Remove from heat and stir in the 0.25 cup cornmeal until smooth. The mixture should be thick but pourable—like a thin batter. If it's too thick, add 1 teaspoon milk at a time until it reaches the right consistency.
Spread this mixture evenly over the tops of the baked potatoes using the back of a spoon. You want a thin, even layer—about ⅛-inch thick. The cornmeal will create that perfect crispy crust we're after. Return the potatoes to the oven for 10-12 minutes until the topping is golden brown and crispy.
Garnish and Serve Warm
Remove the potatoes from the oven and let them cool for 2 minutes. Sprinkle with the 2 tbsp chopped chives and serve immediately with the 0.25 cup sour cream on the side. The contrast of warm, cheesy potatoes with cool sour cream is what makes this dish special.
Here's a pro tip: If you're making these ahead, you can assemble them up to the second baking step and refrigerate for up to 4 hours. Just add 5-10 minutes to the second baking time if they're cold. The key to success is that crispy topping—don't skip the cornmeal step, even if it seems like extra work. Trust me, it's worth it.
Pro Tips For Making America'S Test Kitchen Twice Baked Potatoes
- USE A POTATO MANDOLINE: The ATK recipe calls for thin, even slices—but if you don’t have a mandoline, you’ll spend 20 minutes hacking at potatoes with a knife. I learned this the hard way: uneven slices mean uneven baking, and that’s when your top layer turns to glue instead of crispy perfection. Rent one if you don’t own it—your future self will curse you if you don’t.
- SALT THE POTATOES BEFORE BAKING: This isn’t just about flavor—it’s about texture. Sprinkle a generous pinch of salt (about ½ teaspoon per potato) directly onto the raw potato slices before the first bake. The salt draws out moisture, which means your slices won’t steam into mush when they hit the oven. Trust me, your first batch will taste bland and soggy if you skip this.
- DON’T SKIP THE CORNMEAL RUB: The ATK recipe insists on tossing the baked potato slices in cornmeal before the second bake, and I get why people want to cut corners—it feels like extra work. But here’s the thing: that cornmeal isn’t just for show. It creates a dry, crunchy barrier between the creamy filling and the crispy exterior. If you sub flour or skip it, your top layer will turn out greasy instead of golden.
- BAKE THE FIRST LAYER UNTIL SOFT, NOT CRISPY: The recipe says to bake the potato slices until “just tender,” but I’ve seen people pull them out too early—and that’s when the filling leaks out like a sad, runny mess. Press a slice with your finger: if it gives slightly but still holds its shape, it’s ready. If it crumbles, you’ve overdone it. The goal is flaky, not brittle.
Pro cooking tips for this dish
Potato Prep Perfection
Start with medium russet potatoes—they’re the secret to fluffy, creamy centers. Pierce them all over with a fork before baking to prevent explosions (yes, this happens!). I bake mine at 425°F for 45-50 minutes until a knife slides in effortlessly.
The key here is even baking—rotate the tray halfway through for consistent doneness. Let them cool 10 minutes before scooping to avoid steam burns. 🥔
Cheese Melting Mastery
Sharp cheddar is non-negotiable—pre-shredded cheese won’t melt as smoothly. Use a block cheese and grate it yourself for the best texture. When mixing with the potatoes, add the heavy cream and warm milk gradually to avoid a gummy consistency.
I like to microwave the cheese for 20 seconds first to help it melt faster into the warm potatoes. This creates that velvety, pull-apart perfection we’re after. 🧀
Cornmeal Crust Secrets
For that crispy, golden topping, use fine-ground cornmeal—it spreads more evenly than regular. Melt the butter first, then whisk in the cornmeal until smooth. The mixture should be thin but coatable—like pancake batter.
Spread it ⅛-inch thick over the potatoes before the final bake. Pro tip: Use the back of a spoon for even distribution. 🌽
Two-Stage Baking
The first bake at 375°F develops the cheesy filling, while the second bake crisps the cornmeal topping. Don’t rush the first bake—25-30 minutes until lightly golden ensures the potatoes hold together.
After adding the cornmeal topping, bake just 10-12 minutes—any longer risks burning. The internal temp should reach 165°F by the end. 🌡️
Garnish Like a Pro
Fresh chives add a bright finish, but green onions or parsley work too. For extra flair, sprinkle crushed black pepper or a pinch of smoked paprika on top before the final bake.
Serve with sour cream on the side—its coolness balances the warm, cheesy potatoes. I like to drizzle with hot sauce for guests who want heat. 🌿
Make-Ahead Magic
Assemble the potatoes up to the second bake and refrigerate for up to 4 hours. When ready to finish, add 5-10 extra minutes to the second bake time. For freezer prep, assemble fully baked (without topping), freeze, and bake from frozen at 375°F for 30-40 minutes.
The cornmeal topping should always go on fresh after thawing for the best texture. ❄️

Frequently asked questions
Why does America's Test Kitchen use cornmeal instead of breadcrumbs for the topping?
Cornmeal creates a lighter, crispier topping that won't get soggy like breadcrumbs can. The fine texture also spreads more evenly, giving you that perfect golden crust without weighing down the potatoes. Plus, it adds a subtle sweetness that complements the cheddar beautifully.
Can I make these potatoes ahead of time for a dinner party?
Assemble the potatoes up to the second baking step, then refrigerate for up to 4 hours. When ready to serve, just add 5-10 extra minutes to the final bake time. For freezing, assemble fully baked (without topping), freeze, and bake from frozen at 375°F for 30-40 minutes. Always add the cornmeal topping fresh after thawing for best results.
What's the best way to tell when the potatoes are fully cooked in the first bake?
Use the knife test: A fork or knife should slide in easily with no resistance when the potatoes are fully tender. For russets, this typically takes 45-50 minutes at 425°F. The potatoes should also feel slightly soft when gently squeezed. Overcooking can make them dry, so aim for just fork-tender.
Can I substitute sharp cheddar with another cheese?
While sharp cheddar is ideal, you can use pepper jack or Gruyère for a similar melt. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. If you must use a substitute, grate your own block cheese for the best texture and flavor.
Why do my twice-baked potatoes sometimes fall apart?
This usually happens when the potatoes aren't fully cooked in the first bake or if they're overfilled with cheese mixture. Make sure to bake the potatoes until completely tender before scooping, and leave about ¼-inch thick shells. Also, don't overmix the filling—just combine until the cheese melts completely.
