These creamy scalloped potatoes are layered with thinly sliced potatoes and baked in a rich garlic cream sauce with Dijon and nutmeg, finished with a golden Parmesan crust.
Preheat oven to 375°F and butter a 9x13 baking dish.
Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 minute.
Slowly whisk in milk and heavy cream. Add garlic, salt, pepper, onion powder, smoked paprika, Dijon mustard, and nutmeg.
Cook for 3–4 minutes, whisking until the sauce thickens.
Arrange half of the sliced potatoes in the baking dish. Pour half the sauce over the potatoes.
Add the remaining potatoes and pour the rest of the sauce on top.
Sprinkle cheddar cheese over the top if using.
Drizzle melted butter and sprinkle Parmesan over the top.
Cover with foil and bake 45 minutes.
Remove foil and bake 20–25 minutes more until potatoes are tender and golden.
Rest 10–15 minutes before serving.

Nettie’s Kitchen Tips
Slice potatoes thin and evenly
Thin slices cook more evenly and help the sauce thicken naturally.
A mandoline slicer works great
It saves time and ensures consistent slices.
Add onions for extra flavor
Thinly sliced onion layered between the potatoes adds wonderful flavor.
Try a steakhouse cheese blend
Use ½ cup Gruyère and ½ cup cheddar for an even richer flavor.
