Ingredients for america's test kitchen scalloped potatoes

Six ingredients, one showstopping side. Crispy layers demand precision—no shortcuts here.

Ingredient Amount Notes
Yukon Gold Potatoes 🥔 2 ½ lb Thinly sliced, even thickness
Sharp White Cheddar Cheese 🧀 1 ½ cups Freshly grated, block preferred
Heavy Cream 🥛 1 cup Full-fat for richness
White Wine Vinegar 🍷 2 tbsp For signature tang
Unsalted Butter 🧈 ½ cup Melted, salted added later
Diamond Crystal Kosher Salt 🧂 1 ½ tsp Fine grain preferred

The potatoes make or break this dish. Yukon Golds are non-negotiable—their waxy texture holds up perfectly when sliced thin. Grab a mandoline slicer for even cuts, or use a sharp chef's knife if you're patient. Whole Foods or Trader Joe's carry the best selection of Yukon Golds—look for firm, unblemished potatoes. The cheese? Sharp white cheddar from a block (like Cabot) melts beautifully and delivers that signature tang. Pre-grated gets clumpy and lacks flavor, so invest 30 seconds to grate it yourself. The vinegar is your secret weapon—white wine vinegar adds brightness without overpowering the dish.

No sharp cheddar? Pepper jack or Gruyère work in a pinch, but the tang will be different. Heavy cream substitute? Half-and-half plus 1 tbsp extra butter gets you close, though the texture won't be quite as rich. Short on butter? Olive oil works too, though it'll change the flavor profile slightly. The salt is critical—Diamond Crystal dissolves perfectly, but any fine kosher salt will do. Want extra crispiness? Toss the sliced potatoes in cold water for 10 minutes before layering to remove excess starch. Trust me, it's worth the extra minute.

This reheats like a dream—honestly better the next day as flavors meld. Store leftovers covered in the fridge for up to 4 days, or freeze for 3 months. For freezing, assemble the casserole, then wrap tightly in foil before covering with plastic wrap. When reheating, cover with foil for 10 minutes to melt the cheese, then uncover for the final 5 minutes to crisp the top. The first bite out of the oven? That's when the magic happens—crispy edges, creamy centers, and that vinegar-kissed tang cutting through every layer.

Step-by-step instructions for america's Test Kitchen scalloped potatoes

Here's the foolproof method for achieving that signature crispy top and creamy layers—every time.

1

Slice and Parboil the Potatoes for Perfect Texture

Using a mandoline or sharp knife, slice the 2.5 lb Yukon Gold Potatoes into ¼-inch thick rounds—consistent thickness ensures even cooking. I like to keep the slices whole rather than breaking them up, as this creates a more elegant layered effect.

Place the sliced potatoes in a single layer in a large pot and cover with cold water by about 1 inch. Bring to a boil over medium-high heat, then immediately reduce to a gentle simmer. Cook for exactly 4 minutes—this partial cooking prevents a gummy interior while maintaining structure. Drain thoroughly in a colander, then rinse with cold water to stop the cooking process and remove excess starch.

Real talk: Skipping the parboil step often leads to mushy potatoes. The key is that 4-minute window—any longer and they'll turn to mush, any shorter and they won't develop proper texture. Pat them completely dry with a clean kitchen towel before proceeding.

2

Create the Vinegar-Kissed Cream Sauce

In a medium saucepan, melt the 0.5 cup unsalted butter over medium-low heat. Once fully melted, whisk in the 1 cup heavy cream and bring to a bare simmer. Here's where the magic happens: slowly whisk in the 2 tbsp white wine vinegar—this creates that signature tang that balances the richness.

Simmer the mixture for 3-4 minutes until it thickens slightly but doesn't boil. Remove from heat and stir in the 1.5 tsp Diamond Crystal kosher salt, making sure it dissolves completely. The sauce should coat the back of a spoon but remain pourable—this ensures it will perfectly coat each potato layer without making them soggy.

I know it seems counterintuitive to add vinegar to a creamy potato dish, but trust me—it cuts through the richness and makes every bite more complex. Taste as you go; if you want more tang, add another ½ tsp vinegar, but don't overdo it or the dish will taste sharp.

3

Layer with Precision for Maximum Crisp

Preheat your oven to 375°F. Generously butter a 9x13-inch baking dish—this prevents sticking and creates a barrier between the potatoes and the pan. Start by arranging a single layer of potato slices in the bottom, slightly overlapping them if needed to cover the surface completely.

Pour about ⅓ of the cream sauce evenly over the first layer, then sprinkle ⅓ of the 1.5 cups sharp white cheddar cheese (about ½ cup) over the top. Repeat this layering process twice more, ending with a final layer of potatoes topped with the remaining sauce and cheese. The key is to distribute the sauce evenly—this prevents dry spots in your finished dish.

Here's the thing—don't press down on the layers. The potatoes need room to expand slightly as they cook, and compacting them will lead to a dense, unappetizing texture. The layers should look like they're just gently nestled together, not forced into submission.

4

Bake to Golden Perfection with the Crisp Top Trick

Cover the baking dish tightly with double-layered aluminum foil—this traps steam and helps develop that creamy texture throughout. Bake for 45 minutes at 375°F, then remove the foil and increase the oven temperature to 425°F. This second phase is critical for achieving that signature crispy top.

Return the dish to the oven for 15-20 minutes until the top is deep golden brown and the edges are bubbling. You'll see the cheese pulling away from the edges and forming a beautiful crust—this is what we're after. If the top browns too quickly, tent it loosely with foil to prevent burning while still allowing it to crisp.

This high-heat finish might seem risky, but it's what creates that restaurant-quality texture. The contrast between the crispy top and creamy interior is what makes these scalloped potatoes truly special. Don't be tempted to peek at the dish during this final phase—every time you open the oven, you risk losing that crispy finish.

5

Rest and Serve for Maximum Flavor Development

Remove the dish from the oven and let it rest for 10-15 minutes before serving. This resting period is crucial—it allows the layers to set slightly and the flavors to meld together. The potatoes will continue cooking slightly from residual heat, so don't cut into them immediately or you'll end up with a runny mess.

When you're ready to serve, run a thin knife around the edges to loosen the potatoes from the dish. Slide a large spatula underneath and carefully lift the entire casserole onto a serving platter. The layers should hold together beautifully, with that perfect crispy top contrasting against the creamy interior.

Each bite should deliver creamy, tender potatoes with a tangy kick from the vinegar and a sharp cheddar finish. Serve immediately with a simple green salad or roasted vegetables to let the potatoes shine as the star of the show. The leftovers? Even better the next day—if there are any!

Make-ahead tips for america's test kitchen scalloped potatoes

Prep Ahead Strategy

Assemble your scalloped potatoes up to 24 hours ahead and refrigerate uncovered. This allows the flavors to meld and the layers to settle before baking. I always prep mine the night before—just cover tightly with plastic wrap and pop it in the fridge.

The cold start helps create even more crispy edges when you bake it later. 💫

Freezer-Friendly Assembly

For long-term prep, assemble the dish completely (including sauce and cheese) in a 9x13-inch baking dish, then cover tightly with double-layered foil followed by plastic wrap. Freeze for up to 3 months.

When ready to bake, thaw overnight in the fridge, then bake as directed—just add 10 extra minutes covered at the beginning to account for the cold start.

Partial Prep Shortcut

Save time by prepping just the potatoes and sauce separately. Parboil and dry the potato slices, then store them in an airtight container with a paper towel to absorb moisture. Keep the sauce ingredients (butter, cream, vinegar, salt) in a separate container.

Assemble and bake fresh—this cuts your active prep time to just 15 minutes before baking. Honestly, this is my go-to method for busy weeknights.

Reheating Leftovers

Leftover scalloped potatoes reheat beautifully. Cover with foil and warm in a 350°F oven for 15-20 minutes until heated through. For a crispy top, finish uncovered for the last 2-3 minutes.

Microwave reheating works too—cover with a damp paper towel and heat in 30-second intervals until hot, adding a splash of milk or cream if needed to restore creaminess.

Make-Ahead Serving Hack

Want to impress guests without last-minute stress? Assemble the dish completely, then refrigerate it covered. When ready to serve, bake as directed but add 5 extra minutes uncovered at the end to ensure a crispy top.

The cold start means you'll need that extra time to achieve perfect browning. Trust me, your guests will never know you made it ahead!

Flavor Boost Tip

If prepping ahead, add a pinch of nutmeg or black pepper to the sauce before refrigerating. These spices intensify during storage, adding extra depth of flavor when you reheat or bake.

I also recommend adding a splash of milk or cream when reheating to restore moisture lost during storage. This keeps every bite as creamy as fresh-baked. 🌟

Frequently asked questions

1

Why does America's Test Kitchen use vinegar in the sauce?

The white wine vinegar creates that signature tangy brightness that cuts through the richness of the cream and cheese. It prevents the dish from tasting too heavy while adding complexity. Without it, you'd miss the signature flavor that makes these scalloped potatoes stand out from classic versions.

2

Can I use a different type of potato?

Yukon Gold potatoes are ideal because their waxy texture holds up beautifully when sliced thin. Russets work in a pinch but tend to get gummy. Avoid starchy potatoes like red or white—they'll fall apart during baking. If you must substitute, try fingerling potatoes for a different texture.

3

How do I get the top extra crispy?

After the initial baking, increase the oven temperature to 425°F and bake uncovered for 15-20 minutes. This high-heat finish creates the perfect golden crust. For extra crispiness, broil for 1-2 minutes at the very end—just watch closely to avoid burning.

4

Can I make this dish ahead of time?

Assemble the dish up to 24 hours ahead and refrigerate uncovered. This helps develop flavors and creates crispier edges when baked. For freezing, assemble completely, wrap tightly, and bake from frozen with 10 extra minutes covered at the start. The texture stays perfect!

5

What's the best way to reheat leftovers?

Cover with foil and warm in a 350°F oven for 15-20 minutes, then uncover for the last 2-3 minutes to restore crispiness. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals, adding a splash of milk if needed to maintain creaminess.
