Add the cheeses (reserving some for topping), onion powder, nutmeg, salt, and pepper. Stir until smooth.

Layer half of the sliced potatoes in the baking dish and pour half of the cheese sauce over them.

Repeat with the remaining potatoes and sauce, then sprinkle the reserved cheese on top.

FAQs

Can I make Potatoes Au Gratin ahead of time?

What’s the difference between scalloped potatoes and au gratin?

Au gratin includes cheese, while scalloped potatoes are typically just cooked in a creamy sauce.

Can I use other types of potatoes?

Yukon Golds work well too, but avoid waxy potatoes as they may not soften properly.

Why is my sauce separating?

Ensure the sauce is well emulsified and avoid overheating. Stir continuously while cooking.

How do I get a crispy top?

Remove the foil in the final baking stage to allow the top to brown and bubble.

Can I freeze Potatoes Au Gratin?

Freezing is not recommended as the texture of the potatoes may change upon reheating.

What kind of cheese is best?

Gruyère and sharp cheddar offer a great combination of meltability and flavor.

Can I make it dairy-free?

Use plant-based butter, milk, and cheese alternatives, though texture and taste will differ.
