  • 2.5 pounds Yukon gold potatoes peeled and thinly sliced
  • 1/4 cup butter
  • 1/4 cup all-purpose flour
  • 2 cups milk
  • 1 cup sharp cheddar divided
  • 1 cup gouda divided
  • 1/2 cup grated Parmesan
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon dried mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper


  • Preheat oven to 350F. In a small saucepan, melt the butter over medium heat. Once the butter is melted, whisk in the flour.
  • Slowly whisk in the milk. Once the milk is warm, stir in 1/2 cup of cheddar, 1/2 cup gouda, and the Parmesan. Then stir in the garlic powder, dried mustard, salt, and pepper.
  • Layer half the potatoes in a greased 2-quart baking dish. Pour half the cheese sauce over the potatoes. Then layer the other half of the potatoes and top with the remaining cheese sauce Sprinkle with the rest of the shredded gouda and cheddar cheese.
  • Cover with foil and bake for 45 minutes. Then remove foil and bake for an additional 15 minutes.
  • Once done, remove and allow to rest for 10-15 minutes before serving.


  • Stir the sauce together using a whisk. This will quickly help the dry ingredients to incorporate into the milk.
  • The potatoes should be sliced as finely as possible. Thicker sliced potatoes will take longer to cook through.
  • Add more salt to taste if desired
  • Check the potatoes for doneness around the 45-minute mark. If they are not tender, cover the potatoes with foil and continue to bake until tender.
