Why you’ll love this dish

This recipe hits a lot of home-cooking sweet spots. It is budget friendly, since basic pantry staples and a few large potatoes feed several people. The texture contrast, tender potatoes under a creamy, thickened sauce with a melted cheddar top, feels luxurious without a lot of fuss. It is also forgiving, so if your slices vary a bit in thickness the bake still turns out well, and it reheats beautifully for next-day lunches.

Make it for a comforting weeknight main with a simple salad, or serve it alongside roasted vegetables for an easy weekend spread. It is kid-friendly, customizable for different cheeses, and reliable enough to bring to gatherings where you want predictable results. The garlic powder and butter-flour roux create a sauce that clings to each slice, so you get savory bites with every forkful.

Step-by-step overview

• Preheat the oven and prepare a greased baking dish.
• Make a roux by melting butter, stirring in flour and seasoning.
• Whisk in cream and milk, cooking until the sauce thickens.
• Layer half the potatoes, pour half the sauce, and sprinkle cheese.
• Repeat layers, cover and bake until tender, then uncover to brown.

What you’ll need

4 large potatoes, thinly sliced
2 cups shredded cheddar cheese
1 cup heavy cream
2 cups milk
1/4 cup butter
1/4 cup all-purpose flour
1 teaspoon garlic powder
Salt and pepper to taste
Chopped parsley for garnish (optional)

Notes on ingredients: Yukon Gold or russet potatoes both work well; Yukon Golds stay creamier, while russets break down more for a pillowy texture. Use freshly shredded cheddar if you can, it melts more smoothly than pre-shredded blends that contain anti-caking agents. If you need a lighter finish, swap half-and-half for the heavy cream, but the dish will be less rich.

Step-by-step instructions

1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish.
2. Melt the butter in a saucepan over medium heat. Stir in the flour, garlic powder, salt, and pepper to form a paste.
3. Gradually whisk in the heavy cream and milk, stirring constantly until the sauce thickens and coats the back of a spoon, about 3 to 5 minutes. Remove from heat.
4. Arrange half of the potato slices in an even layer in the prepared dish. Pour half of the sauce over the potatoes, then sprinkle half the shredded cheddar on top.
5. Add the remaining potato slices in a second layer. Pour the remaining sauce over them and sprinkle the rest of the cheese. Smooth the top gently.
6. Cover the dish tightly with aluminum foil and bake for 45 minutes.
7. Remove the foil and bake uncovered for an additional 15 minutes, or until the top is golden and the potatoes are tender when pierced with a knife.
8. Let the casserole rest for 10 to 15 minutes so the sauce sets slightly. Garnish with chopped parsley before serving if desired.

Best ways to enjoy it

Cheesy scalloped potatoes pair well with simple, bright sides that cut through the richness. A crisp green salad dressed with lemon vinaigrette, steamed green beans tossed with a squeeze of lemon, or roasted carrots add texture and color. For a heartier plate, serve them with roasted chicken or grilled vegetables.

Storage and reheating tips

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. To reheat, warm individual portions in the oven at 350°F until hot throughout, about 15 to 20 minutes, which helps preserve a creamy texture and crisps the top. Microwaving works for quick meals, but the sauce may become looser and the top will not crisp.

To freeze, cool the baked dish completely, then wrap tightly with plastic wrap and foil, or transfer portions to freezer-safe containers. Freeze for up to 2 months. Thaw in the refrigerator overnight before reheating in the oven. When reheating from frozen, allow extra time at 350°F and cover with foil until heated through to avoid over-browning.

Helpful cooking tips

• Slice potatoes uniformly, about 1/8-inch thick, for even cooking. A mandoline speeds this up and gives consistent layers.
• The sauce should be thick enough to coat the back of a spoon, but still pourable; it will continue to thicken as it bakes.
• Avoid stacking too many potatoes in one layer, which can leave the center undercooked. A shallow, 9×13 dish yields ideal layers.
• If the top is browning too quickly during the uncovered bake, tent a loose piece of foil over the dish.
• Letting the casserole rest after baking reduces the runniness of the sauce, making cleaner slices when serving.

Creative twists

• Swap half the cheddar for Gruyere for a nuttier flavor and more elastic melt.
• Stir in a cup of sautéed onions or leeks into the sauce for fragrant sweetness.
• Add a handful of chopped fresh herbs like thyme or chives to the sauce before layering for a herb-forward profile.
• For a lighter version, use low-fat milk and omit some of the cream, but expect a thinner sauce and slightly different mouthfeel.
• Sprinkle panko mixed with a little melted butter and extra cheese on top before the final bake for a crunchy topping.

Common questions

How long does it take to prep and cook this casserole?

Plan for about 20 minutes of active prep, mainly slicing potatoes and making the sauce. Baking is roughly 60 minutes in total, including the covered and uncovered phases, so total time is about 1 hour and 20 minutes.

Can I make this ahead and bake later?

Yes, assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. If chilled, you may need to add 10 to 15 minutes to the covered baking time so the center reaches tenderness.

What is the best potato to use for scalloped potatoes?

Yukon Golds are excellent for scalloped potatoes because they have a creamy texture and hold their shape. Russet potatoes also work and give a fluffier interior, but they can break down more during baking.

Can I make this dairy-free or lighter?

For a lighter dish, replace some heavy cream with milk or a lower fat option, keeping in mind the sauce will be less rich. For dairy-free, use a plant-based milk and vegan butter and a dairy-free shredded cheese alternative that melts well, though texture and flavor will differ from the original.
