A creamy, cheesy potato casserole perfect for family gatherings and holiday dinners.

Ingredients

Scale
  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 3 cups whole milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon nutmeg
  • 2 cloves garlic, minced
  • 1 cup shredded Gruyère cheese
  • 1 cup shredded cheddar cheese
  • 2 1/2 pounds Yukon Gold potatoes, peeled and thinly sliced
  • 1/2 cup thinly sliced yellow onion

Instructions

  1. Preheat your oven to 375°F (190°C). Butter a 9×13 inch baking dish.
  2. In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly.
  3. Gradually whisk in the milk until smooth. Bring to a simmer, stirring, and cook until thickened, about 5 minutes.
  4. Remove from heat. Stir in salt, pepper, nutmeg, and minced garlic. Stir in 1/2 cup of the Gruyère and 1/2 cup of the cheddar cheese until melted and smooth.
  5. Arrange half of the sliced potatoes in the prepared baking dish. Top with half of the sliced onions. Pour half of the cheese sauce over the potatoes and onions.
  6. Repeat the layers with the remaining potatoes, onions, and sauce. Sprinkle the remaining 1/2 cup Gruyère and 1/2 cup cheddar cheese over the top.
  7. Cover the dish with foil. Bake for 45 minutes.
  8. Remove the foil and bake for another 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
  9. Let stand for 10 minutes before serving.

Notes

  • For uniform slices, use a mandoline.
  • You can prepare this casserole up to the point of baking and refrigerate it. Add about 10-15 minutes to the covered baking time if baking from cold.
  • This dish pairs well with roast meats and is a popular choice for holiday meals.
