Our favorite scalloped potatoes recipe is a must-make dish for holiday meals—from Easter to Thanksgiving to Christmas—and any celebration in between. Not only is this rich potato side dish a crowd-pleaser, it's a winner for the cook as it can be assembled ahead of time and baked when it's time to eat.

This comforting, nostalgic dish starts with thinly sliced potatoes simmered with milk and cream. The potatoes and creamy mixture are then layered with Gruyère cheese in a casserole dish and baked, then finished under the broiler for a delicious, crispy top.

What Are Scalloped Potatoes?

Sometimes called a potato bake, scalloped potatoes are a type of potato casserole similar to au gratin potatoes and potatoes dauphinoise. All are rich, creamy dishes made with thinly sliced potatoes layered in a combination of milk and cream. Some recipes call for making a cream sauce, but we think that’s overcomplicating the dish. It’s much better when made by cooking the sliced potatoes in the cream and milk on the stovetop, then layering them in the casserole dish, alternating with the cheese, before baking.

Cheese in Scalloped Potatoes

Not all scalloped potato recipes call for cheese, but ours do. We think the addition of Gruyère cheese, which is one of the best cheeses for melting, takes the simple combination of potatoes and cream to the next level. Some scalloped potatoes recipes use cheddar, but Gruyère is better.

Tips for Making Scalloped Potatoes

  1. Use the right potatoes. We call for Yukon Golds in this recipe and they are key to scalloped potato success. They don’t soak up too much of the cream mixture and hold their shape well.
  2. Slice the potatoes thinly and evenly. Uniform thin slices are the key to a delicious scalloped potatoes dish. If the slices are not the same thickness, they won’t cook evenly. You can use a mandolin, the slicer attachment on your food processor, or a sharp chef’s knife.
  3. Use a glass or ceramic shallow baking dish for scalloped potatoes. It should be large enough to hold all the potato slices and liquid, but not too deep that the potatoes won’t cook through, and the ratio of creamy potatoes to crispy topping is off.

Make Ahead

Our creamy scalloped potatoes can be largely assembled ahead:

  1. Leave off the last portion of cheese, cover the dish with plastic wrap (pressing it directly onto the surface to prevent a skin from forming), and refrigerate it for up to one day.
  2. Remove the dish from the refrigerator 30 minutes before baking. Sprinkle with the remaining cheese, and bake as instructed in recipe.

  9. Broil:

    Remove foil; turn oven to broil. Broil until potatoes are bubbly and browned in places, 3 to 5 minutes. Let cool 15 minutes before serving.

    Letting the scalloped potatoes cool for 15 minutes is important. It is too hot to serve straight from the broiler, and the dish needs time to set. If you cut into it before it cools slightly, the creamy mixture will be liquid and the potatoes too delicate, and the dish will be difficult to serve.

Frequently Asked Questions

Should the sliced potatoes be soaked in water?

No, we don’t call for rinsing the sliced potatoes or for soaking them in water in our scalloped potatoes recipes. Rinsing or soaking will remove the natural starches contained in the potato, which is used to help thicken the dish as it cooks. Rinsing or soaking also makes potatoes more watery—and you don’t want to add water to the creamy dish.


Should scalloped potatoes be covered?

Yes, we cover our creamy scalloped potatoes as they cook in the oven so that the top doesn’t brown before the potatoes are tender and cooked through. Then we remove the parchment-lined foil and finish the dish under the broiler to get a delicious crispy topping.
