Create the ultimate comfort food with this recipe for creamy and cheesy scalloped potatoes. This classic side dish features tender potato layers baked in a rich, velvety cheese sauce, perfect for holiday feasts or weeknight dinners.

Ingredients

Scale
  • 3 lbs Russet potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 4 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 3 cups whole milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 2 cups shredded sharp cheddar cheese, divided
  • 1/2 cup shredded Gruyère or Parmesan cheese

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. Place the thinly sliced potatoes in a large bowl of cold water to prevent browning while you prepare the sauce. Drain well before using.
  3. Make the cheese sauce: In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for one minute, stirring constantly.
  4. Gradually whisk in the milk until the mixture is smooth. Continue cooking, stirring often, until the sauce thickens enough to coat the back of a spoon, about 5 to 7 minutes. Do not let it boil rapidly.
  5. Remove the saucepan from the heat. Stir in the salt, pepper, and nutmeg. Add 1 1/2 cups of the cheddar cheese and all of the Gruyère or Parmesan cheese. Stir until the cheese is completely melted and the sauce is smooth.
  6. Layer the potatoes: Arrange one-third of the drained potato slices evenly in the bottom of the prepared baking dish. Pour one-third of the cheese sauce over the potatoes.
  7. Repeat the layering process twice more: potatoes, then sauce, ending with a final layer of potatoes.
  8. Pour any remaining sauce over the top layer of potatoes, ensuring most slices are covered. Sprinkle the remaining 1/2 cup of cheddar cheese evenly over the top.
  9. Bake uncovered for 50 to 60 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown and bubbly.
  10. Let the scalloped potatoes rest for 10 minutes before serving. This allows the sauce to set for a richer texture.

Notes

  • For a richer flavor, use half-and-half instead of whole milk in the sauce.
  • If you want to add ham, layer in 1 cup of diced cooked ham between the potato layers.
  • To achieve the perfect thin slice, use a mandoline slicer if you have one.
