The epitome of traditional comfort food, scalloped potatoes seem to feed the stomach and even the soul-- maybe it’s because so many grandmas in the world made them for their loved ones! I’ll walk you through how to make a creamy cheddar cheese sauce for this casserole that's simple and completely satisfying. I guarantee this will be the first empty dish at any potluck.
Preheat oven to 350 degrees. Coat a one-quart casserole dish with nonstick spray.
In a small saucepan over medium-high heat, melt butter until foaming. Whisk in flour until cooked through, about 1 minute.
Whisk in milk until smooth. Bring sauce to a boil, reduce heat, and cook until thickened. Stir in 1 cup cheese and season to taste with salt and pepper (I like 1 teaspoon salt and 1/2 teaspoon pepper).
Layer half the sliced potatoes in bottom of prepared casserole dish. Top with half the cheese sauce. Layer the second half of potatoes on top and top with remaining cheese sauce.
Sprinkle remaining 1/2 cup cheese on top. Sprinkle with paprika for color. Bake uncovered for 1 hour. Let stand 10 minutes before serving.
