How to Make Cheesy Fried Onion Scalloped Potatoes

Step 1: Prepare the Potatoes

Start by peeling the potatoes and slicing them evenly about 1/8-inch thick using a mandoline or sharp knife — uniform slices ensure even cooking and a beautiful layered look.

Step 2: Make the Cheese Sauce

In a saucepan, melt butter over medium heat, then whisk in flour to form a roux. Slowly add heavy cream while stirring until thickened, then mix in your grated cheese and season with garlic powder, salt, and pepper to create a smooth, creamy sauce.

Step 3: Layer the Potatoes

Grease a baking dish, then spread a layer of sliced potatoes on the bottom. Pour some cheese sauce over the potatoes, then repeat layers until all potatoes and sauce are used up, finishing with a layer of cheese sauce on top.

Step 4: Bake the Potatoes

Cover the dish with foil and bake at 350°F (175°C) for about 45 minutes to allow the potatoes to soften and the flavors to meld.

Step 5: Add the Fried Onion Topping

Remove the foil, evenly sprinkle the crispy fried onions on top, and return the dish to the oven uncovered. Bake for another 15 minutes until the onions are golden and the potatoes are bubbling deliciously.

Pro Tips for Making Cheesy Fried Onion Scalloped Potatoes

• Slice Potatoes Uniformly: Use a mandoline for consistent thickness, preventing uneven cooking.
• Use Sharp Cheese: Sharp cheddar gives an intense flavor that balances the creamy sauce perfectly.
• Don’t Skip the Roux: It thickens the sauce and keeps it velvety, preventing it from being watery.
• Cover While Baking: Keeps moisture in, ensuring tender potatoes before crisping the topping.
• Freshly Made Fried Onions: For even better flavor, make your own crispy onion topping instead of store-bought.
