How to Make Cheesy Scalloped Potato Bake

Preheat your oven to 350°F (175°C), ensuring even heat for a perfectly bubbly, golden crust on your Cheesy Scalloped Potato Bake.
Slice 2½ pounds russet potatoes and 1 large yellow onion into 1/8-inch rounds for tender layers that absorb the creamy sauce beautifully.
Layer half the potato and onion slices in a greased 9×13-inch baking dish, overlapping edges slightly for even coverage and uniform baking.

For the Cheese Sauce:

Melt 4 tablespoons butter in a medium saucepan over medium heat; whisk in ¼ cup flour until golden, creating a smooth roux within 2 minutes.
Whisk in 2 cups whole milk gradually, then stir in 1½ cups shredded cheddar and 1 cup Gruyère until silky, seasoning with salt and pepper.
Assemble pour half the cheese sauce over the potato layers; repeat with remaining potatoes and sauce for evenly cheesy, rich layers.

For the Topping:

Sprinkle ½ cup breadcrumbs evenly on top, then dot with 1 tablespoon butter for a crispy, golden finish that adds irresistible crunch.

Expert Tips for Cheesy Scalloped Potato Bake

Choose the right potatoes: Use starchy russet potatoes for creamy layers that soak up the cheese sauce without becoming mushy.
Slice uniformly: Thin, even slices (about 1/8 inch) ensure all potatoes cook evenly and absorb sauce perfectly.
Make a smooth sauce: Whisk the roux well and gradually add milk to avoid lumps, creating a silky cheese sauce that clings to every slice.
Don’t overcrowd the dish: Layer potatoes in a single, slightly overlapping layer to promote even cooking and prevent sogginess.
Check for doneness: Pierce the bake with a fork near the end of baking; potatoes should be tender but not falling apart.
Let it rest: Allow the Cheesy Scalloped Potato Bake to rest before serving so the sauce thickens and slices hold together beautifully.

Cheesy Scalloped Potato Bake Recipe FAQs

What type of potatoes work best for Cheesy Scalloped Potato Bake?
Russet potatoes are your best choice! Their starchy texture melts into tender, creamy layers that soak up the cheesy sauce beautifully without turning mushy.

How long can I store leftovers of this potato bake in the fridge?
Leftover Cheesy Scalloped Potato Bake keeps wonderfully in an airtight container for up to 3 to 4 days. I recommend reheating it in the oven to maintain that lovely texture and melted cheese goodness.

Can I freeze Cheesy Scalloped Potato Bake for later?

What if my potatoes turn dark or develop spots before cooking?
If you see dark spots all over your sliced potatoes, it’s best to trim away those parts or start fresh. Slight discoloration is normal due to oxidation but won’t affect taste if cooked promptly. Always use firm, blemish-free potatoes for that perfect creamy bake.

Is this recipe safe for people with dairy allergies or pets?
This bake relies on cheese and milk, so it’s not suitable for those with dairy allergies. Also, avoid sharing cheesy ingredients with pets since dairy can upset their digestion. For dairy-free versions, consider substituting with plant-based milk and cheese alternatives, though the texture and flavor will differ.
