Yukon Gold or russet potatoes
Butter
Onion
Garlic
All-purpose flour
Milk
Heavy cream
Salt
Black pepper
Thyme or parsley
Shredded cheese, optional

Directions

Preheat your oven to 375°F (190°C) and lightly grease a baking dish.
Peel the potatoes if desired, then slice them thinly and evenly for consistent cooking.
In a saucepan, melt the butter over medium heat. Add the onion and cook until softened, then stir in the garlic.
Sprinkle in the flour and cook for about 1 minute, stirring constantly.
Gradually whisk in the milk and cream until smooth. Season with salt, pepper, and thyme or parsley.
Cook the sauce for a few minutes until it begins to thicken slightly.
Arrange a layer of sliced potatoes in the prepared baking dish. Spoon some sauce over the top. Repeat the layers until all the potatoes and sauce are used.
Add cheese between layers or on top if you want a richer, more gratinéed finish.
Cover with foil and bake for 45 minutes.
Remove the foil and continue baking for 25 to 35 minutes, or until the potatoes are fork-tender and the top is golden.
Let the dish rest for 10 to 15 minutes before serving so the sauce can settle and thicken.

Variations

One of the best things about scalloped potatoes is how easy they are to adapt. For a more classic version, leave out the cheese and let the creamy sauce shine on its own. If you prefer something richer, add shredded cheddar, Gruyère, or Parmesan for extra flavor.

You can also customize the seasonings. Fresh thyme adds an earthy note, while a pinch of nutmeg gives the sauce a deeper, old-fashioned warmth. Thinly sliced onions layered with the potatoes add extra sweetness, side dish into a more filling main course.

For a lighter version, use all milk instead of a mix of milk and cream. You can also swap in sweet potatoes for part of the potatoes to create a slightly sweeter, more colorful variation.

Storage/Reheating

Store leftover scalloped potatoes in an airtight container in the refrigerator for up to 4 days. Make sure they cool before storing.

To reheat, place a portion in the microwave and warm in short intervals until heated through. For larger amounts, reheat in the oven at 350°F (175°C), covered with foil, until hot. If the potatoes seem a little dry, add a splash of milk or cream before reheating to help restore the creamy texture.

Scalloped potatoes can also be frozen, though the texture of the sauce may change slightly after thawing. Freeze in a tightly wrapped container for up to 2 months, then thaw overnight in the refrigerator before reheating.

FAQs

What is the difference between scalloped potatoes and au gratin potatoes?

Scalloped potatoes are usually made with a creamy sauce and may or may not include cheese. Au gratin potatoes almost always include cheese and often have a more pronounced browned topping.

What type of potatoes work best for scalloped potatoes?

Yukon Gold and russet potatoes are both great choices. Yukon Gold potatoes hold their shape nicely and have a creamy texture, while russets become softer and more tender.

Do I need to peel the potatoes?

No, peeling is optional. Peeled potatoes give the dish a smoother, more classic texture, while unpeeled potatoes add a more rustic feel.

Why are my scalloped potatoes still hard?

This usually happens if the potato slices are too thick or the dish has not baked long enough. Thin, even slices are important for tender results.

Can I make scalloped potatoes ahead of time?

Yes, you can assemble the dish ahead and refrigerate it before baking. You can also bake it earlier in the day and reheat it before serving.

Can I make this recipe without cheese?

Yes. Traditional scalloped potatoes often do not include cheese, so the dish is still rich and delicious without it.

How do I keep the sauce from curdling?

Use moderate heat when making the sauce and avoid boiling it too hard. Full-fat dairy also helps create a smoother, more stable sauce.

How thin should the potatoes be sliced?

They should be sliced about 1/8 inch thick. Thin slices help the potatoes cook evenly and absorb the sauce well.

Can I freeze scalloped potatoes?

Yes, although the texture may be slightly softer after thawing. They are best frozen after baking and cooling completely.

Conclusion

Scalloped potatoes are a timeless side dish that brings warmth and comfort to any meal. With their tender layers, creamy sauce, and golden finish, they are easy to love and even easier to serve for both weeknight dinners and special occasions.
