Ingredients

  • 4 cups thinly sliced russet potatoes about 3–4 medium
  • 2 tbsp butter
  • 2 tbsp all-purpose flour
  • 1 1/2 cups milk
  • 1 cup shredded cheddar cheese
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/4 cup grated Parmesan cheese optional

Instructions

  • Preheat oven to 375°F. Grease a 9x9-inch baking dish with butter or cooking spray.
  • In a medium saucepan over medium heat, melt butter. Whisk in flour and cook for 1–2 minutes to form a roux.
  • Slowly whisk in milk, stirring constantly until the sauce thickens (about 4–5 minutes).
  • Stir in cheddar cheese, garlic powder, onion powder, salt, and pepper. Remove from heat once cheese is melted and sauce is smooth.
  • Arrange half of the sliced potatoes in the baking dish. Pour half of the cheese sauce over the potatoes.
  • Layer the remaining potatoes on top and pour the rest of the cheese sauce evenly over them.
  • Sprinkle Parmesan cheese on top if using.
  • Cover with foil and bake for 40 minutes.
  • Remove foil and bake for another 20–25 minutes until the top is golden and bubbly and potatoes are fork-tender.
  • Let sit for 10 minutes before serving.
