Ingredients for Cheesy Scalloped Potatoes
For the Potatoes
- Russet or Yukon Gold potatoes (about 3 pounds): Create tender layers that soak up the sauce well. Swap idea: Russets are softer; Yukon Golds are creamier.
- Salt and black pepper: Season the layers so the potatoes do not taste flat. Swap idea: Season lightly between layers.
- Onion, thinly sliced, optional: Adds gentle savory flavor between the potatoes. Swap idea: Shallots are a milder option.
For the Cheese Sauce
- Butter (4 tablespoons): Starts the roux and adds richness. Swap idea: Unsalted butter is easiest to control.
- All-purpose flour (1/4 cup): Thickens the sauce. Swap idea: Use a gluten-free blend if needed.
- Milk (2 cups): Builds the creamy sauce base. Swap idea: Whole milk gives the best texture.
- Heavy cream (1 cup): Makes the sauce extra luxurious. Swap idea: Use more milk for a lighter dish.
- Cheddar cheese (2 cups, shredded): Adds that cozy cheesy flavor everyone loves. Swap idea: Gruyère or Monterey Jack can be mixed in.
- Garlic (1 clove, minced): Adds savory depth to the sauce. Swap idea: Garlic powder works in a pinch.
- Thyme or parsley: Bring a little freshness to a rich dish. Swap idea: Use dried thyme if needed.
Cheesy Scalloped Potatoes Recipe Step-by-Step
- 1. Preheat the oven to 375°F and grease a casserole dish. Slice the potatoes evenly, ideally about 1/8-inch thick, so they cook at the same rate. A mandoline is very helpful here.
- 2. Make the sauce by melting the butter in a saucepan over medium heat. Whisk in the flour and cook for 1 minute, then slowly pour in the milk and cream while whisking until smooth.
- 3. Simmer the sauce for 3 to 5 minutes until slightly thickened, then stir in the garlic, most of the cheese, salt, and pepper. Keep whisking until the cheese melts into a smooth sauce.
- 4. Layer half of the potatoes in the dish, season lightly, and pour over some of the sauce. Repeat with the remaining potatoes and sauce, then sprinkle extra cheese on top.
- 5. Cover with foil and bake for 45 minutes. Uncover and bake for another 20 to 30 minutes, until the potatoes are fork-tender and the top is golden. Rest for 10 minutes before serving so the sauce thickens slightly.
Tips for Perfect Cheesy Scalloped Potatoes
- Slice the potatoes evenly so they bake at the same speed.
- Shred your own cheese for the smoothest sauce.
- Do not rush the covered bake time because that is what softens the potatoes.
- Rest before serving so the layers hold together better.
- If the top browns too quickly, cover loosely with foil.
Variations & Substitutions
- Add a pinch of smoked paprika for a warmer flavor.
- Mix in Gruyère for a more classic au gratin feel.
- Layer in sautéed onions for extra sweetness.
- Use half sweet potatoes for a different twist.
- Turn leftovers into breakfast potatoes with a fried egg.
Storing & Reheating
Store Cheesy Scalloped Potatoes in the refrigerator for up to 4 days. Reheat covered in the oven so the sauce stays creamy. Freeze after baking for up to 2 months; thaw overnight in the refrigerator and reheat until hot all the way through.
