Appliances and Special Utensils

Ingredients

  • 4 large russet potatoes, peeled and thinly sliced
  • 1 medium onion, thinly sliced
  • 3 cups shredded cheddar cheese
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon paprika
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C).

  2. Prepare Baking Dish: Grease a 9×13-inch baking dish with butter or nonstick cooking spray.

  3. Make Cheese Sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until smooth and bubbly. Gradually whisk in the milk, continuing to whisk until the mixture is smooth and starts to thicken, about 3-5 minutes. Add the salt, black pepper, garlic powder, and paprika. Stir in 2 cups of the shredded cheddar cheese until melted and smooth. Remove from heat.

  4. Layer Potatoes and Onions: Arrange half of the sliced potatoes in an even layer in the prepared baking dish. Top with half of the sliced onions. Pour half of the cheese sauce over the potatoes and onions. Repeat the layers with the remaining potatoes, onions, and cheese sauce.

  5. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes. Remove the foil and sprinkle the remaining 1 cup of shredded cheddar cheese over the top. Continue baking, uncovered, for an additional 20-25 minutes, or until the potatoes are tender and the top is golden and bubbly.

  6. Cool and Serve: Let the cheesy scalloped potatoes cool for a few minutes before serving. Garnish with fresh parsley if desired. Enjoy your delicious, homemade Cheesy Scalloped Potatoes!
