What Kind of Potatoes Should I Use?

Yukon Golds are the top pick for this dish. Their buttery texture and ability to hold shape while baking make them ideal for layering. Russets work too if you’re after a fluffier bite, but they may not hold their structure as beautifully.

How To Make the Scalloped Potatoes with Three Cheeses

Step 1: Make the Cheese Sauce

In a medium saucepan, melt the butter over medium heat. Add the chopped onion and sauté until soft, about 4 minutes. Stir in garlic and cook for 1 minute. Sprinkle in the flour and stir constantly for 1 minute to cook off the raw flavor. Gradually whisk in milk and cream until smooth. Add salt, pepper, and thyme. Bring to a simmer and cook until slightly thickened, about 5 minutes.

Step 2: Add the Cheeses

Remove the saucepan from heat and stir in the cheddar and Gruyère cheeses until melted and smooth. Set aside.

Step 3: Assemble the Layers

Preheat the oven to 375°F (190°C). Butter a 9×13-inch baking dish. Arrange half of the sliced potatoes in the bottom of the dish. Pour over half of the cheese sauce. Repeat with remaining potatoes and sauce. Top with Parmesan.

Step 4: Bake Until Bubbly

Cover the dish with foil and bake for 45 minutes. Remove foil and bake for an additional 20-25 minutes until golden and bubbly on top. Let it rest for 10 minutes before serving.

Serving and Storing Scalloped Potatoes with Three Cheeses

This dish is best served hot and fresh out of the oven, garnished with fresh parsley for a touch of color and brightness. Pair it with a roast, grilled vegetables, or a crisp green salad for a balanced meal.

To store leftovers, let the potatoes cool completely before transferring them to an airtight container. They can be refrigerated for up to 4 days. Reheat in the oven at 350°F for about 15-20 minutes or until warmed through.

Frequently Asked Questions

How thin should the potatoes be sliced?

Aim for about 1/8-inch thickness. A mandoline slicer works best for consistent, even slices that cook evenly.

Can I use different cheeses?

Absolutely. Fontina, Monterey Jack, or even smoked Gouda can bring a unique twist to the flavor profile.

Is it okay to prep this ahead of time?

Yes, you can assemble the dish a day in advance. Cover tightly and refrigerate, then bake when ready.

What if I don’t have heavy cream?

You can use all whole milk, though the sauce may be slightly less rich. For a lighter option, try half-and-half.

Can I freeze scalloped potatoes?

It’s best not to, as the texture can change significantly after freezing. The sauce may become grainy.

How do I get a crispy top?

Remove the foil during the last 20-25 minutes of baking and make sure to sprinkle cheese on top. Broil for a few minutes at the end if desired.
