There is something so special about a bubbly, golden potato casserole coming out of the oven. This recipe is a favorite in my house because it uses simple pantry staples to create a rich and creamy dish that everyone asks for by name.

My best advice is to slice your potatoes as thinly as you can manage. If you have a kitchen mandoline, now is the time to use it because uniform slices ensure that the potatoes cook evenly and soak up all that delicious creamy sauce.

Ingredients

  • 2 pounds russet potatoes, peeled and thinly sliced
  • 1/4 cup unsalted butter
  • 1/4 cup all purpose flour
  • 2 cups whole milk
  • 1 cup shredded sharp cheddar cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder

Instructions

  1. 1

    Preheat your oven to 375 degrees Fahrenheit and grease a standard casserole dish with a little butter or oil.

  2. 2

    Melt the butter in a saucepan over medium heat, then whisk in the flour and cook for one minute.

  3. 3

    Slowly pour in the milk while whisking constantly to prevent any lumps from forming.

  4. 4

    Add the salt, pepper, and garlic powder, then cook the sauce until it thickens enough to coat the back of a spoon.

  5. 5

    Arrange half of the potato slices in your prepared baking dish.

  6. 6

    Pour half of the white sauce over the potatoes and sprinkle with half of the cheese.

  7. 7

    Repeat the layers with the remaining potatoes, sauce, and cheese.

  8. 8

    Cover the dish with foil and bake for 40 minutes.

  9. 9

    Remove the foil and bake for another 20 minutes until the potatoes are tender and the top is bubbly and golden brown.

💡 Tips

Let the casserole rest for ten minutes after taking it out of the oven so the sauce can settle and thicken. You can keep leftovers in the fridge for up to three days, and they reheat beautifully in the microwave or the oven.
