½ teaspoon kosher salt
2 cups whole milk, (room temperature)
1 ½ cups mild cheddar cheese, (shredded)
Salt and pepper to taste

How to Make Cheesy Scalloped Potatoes

Step 1: Preheat the Oven

Preheat your oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray.

Step 2: Arrange the Potatoes and Onions

Arrange the sliced potatoes and onion rings in the prepared baking dish. Stagger them by alternating layers of potato and onion for even distribution.

Step 3: Make the Cheese Sauce

In a medium-sized saucepan over medium heat:
1. Melt the butter.
2. Mix in the flour and kosher salt, stirring constantly with a whisk for one minute.
3. Gradually stir in the milk until combined.
4. Cook until the mixture has thickened.

Step 4: Add Cheese

Stir in the shredded cheddar cheese all at once. Continue stirring until melted and smooth, about 30-60 seconds.

Step 5: Combine Everything

Pour the cheese sauce evenly over the arranged potatoes and onions. Cover the dish with aluminum foil.

Step 6: Bake Until Tender

Bake in your preheated oven for 85-90 minutes or until the potatoes are tender when pierced with a fork.

Step 7: Broil for Crispiness (Optional)

For a crispy topping, change your oven setting to broil after baking. Broil until golden brown, watching closely to prevent burning.

Season with salt and pepper to taste before serving warm. Enjoy your delicious Cheesy Scalloped Potatoes!
