Ingredients
- 2 tablespoons unsalted butter
- 1 medium onion ¼-inch diced
- 6 garlic cloves minced (about 2 tablespoons)
- 2 cups whole milk
- 2 teaspoons kosher salt divided
- ¼ teaspoon ground black pepper
- 3 pounds Yukon Gold potatoes about 6 to 8 medium
- 3 tablespoons all-purpose flour
- 6 ounces sharp cheddar cheese shredded (about 1 ½ cups)
- 1 ounce Parmesan cheese shredded (about ¼ cup)
Directions
- Place a rack in the center of your oven and preheat to 375°F. Coat a 9×13-inch casserole dish with nonstick spray and set aside.

- Lightly mist a large sheet of aluminum foil with nonstick spray. Cover the dish with foil spray-side down. Bake the scalloped potatoes for 35 minutes, then uncover and bake for an 25 additional minutes, until the potatoes are tender when pierced with a fork.
- Remove the dish from the oven and sprinkle with the Parmesan cheese. Turn the oven to broil and return the pan to the oven for 1 to 3 minutes, until the cheese is golden brown and bubbly. Don’t walk away and let them burn!
- Allow the potatoes to stand at room temperature for 20 to 25 minutes prior to serving to allow the milk mixture to set and thicken (don’t worry, they
