Ingredients for Scalloped Potatoes

Here’s everything you’ll need to make this indulgent side dish:

Yukon Gold potatoes – Creamy and buttery, they hold their shape beautifully when baked.
Unsalted butter & all-purpose flour – Form a roux to thicken the luscious cream sauce.
Whole milk & vegetable broth – A blend that keeps the sauce rich but not too heavy.
Fresh garlic & chopped onion – For a savory base with loads of flavor.
Fresh thyme – Adds herby brightness; dried thyme works in a pinch.
Sharp cheddar cheese – Melty, tangy, and perfectly cheesy.
Salt & black pepper – For seasoning the layers just right.

Pro Tip: Use freshly grated cheddar for the smoothest melt.

Scalloped Potatoes vs. Potatoes au Gratin: What’s the Difference?

Technically, scalloped potatoes are baked in a creamy sauce without cheese, while potatoes au gratin include cheese between the layers.

That said, the version I grew up with always had cheese—so that’s what I’m sharing here. You can call them whatever you like, but one thing’s for sure: they’re absolutely delicious.

How to Make Scalloped Potatoes from Scratch

Ready to layer up the goodness? Here’s a step-by-step guide:

1. Slice the Potatoes Thinly

Cut potatoes into ⅛-inch slices for even cooking.
A mandoline slicer works great, but a sharp knife will do the job too.

2. Prepare the Cream Sauce

Melt butter in a skillet and whisk in flour to make a roux.
Slowly add milk, then broth, whisking constantly until smooth.
Stir in garlic, thyme, salt, and pepper. Simmer until lightly thickened (about 2–3 minutes).

3. Assemble the Casserole

Preheat oven to 400°F.
In a greased 9x13-inch baking dish, layer half the sliced potatoes and onions.
Pour half the sauce over the top and sprinkle with 1 cup of cheddar cheese.
Repeat the layers with the remaining potatoes, onions, sauce, and cheese.

4. Bake

Cover with foil and bake for 30 minutes.
Remove foil and continue baking 35–40 minutes, or until the potatoes are tender and the top is golden brown.

5. Cool and Serve

Let rest at room temperature for 15–20 minutes before serving. This helps the sauce thicken and flavors settle.
