Ingredients

Scale
  • 4 large russet or Yukon gold potatoes, peeled and thinly sliced
  • 2 cups heavy cream
  • 1 cup milk
  • 4 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 2 cloves garlic, minced
  • 2 cups shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • Salt and pepper to taste
  • 1/4 teaspoon nutmeg (optional)
  • 1 teaspoon chopped fresh thyme (optional)
  • 1/4 cup breadcrumbs (optional, for topping)
  • Fresh parsley for garnish

Instructions

  • Preheat oven to 375°F (190°C).
  • In a saucepan, melt butter over medium heat. Add minced garlic and sauté until fragrant.
  • Stir in flour to form a roux. Gradually whisk in heavy cream and milk, cooking until the mixture thickens.
  • Remove from heat and stir in cheddar cheese, Parmesan cheese, salt, pepper, and nutmeg.
  • In a greased baking dish, arrange a layer of thinly sliced potatoes. Pour a portion of the cheese sauce over the potatoes. Repeat layers until all potatoes and sauce are used.
  • Sprinkle breadcrumbs and fresh thyme over the top, if using.
  • Cover with foil and bake for 45 minutes. Remove foil and bake for an additional 15 minutes or until golden and bubbly.
  • Garnish with fresh parsley before serving.

Notes

  • For an extra creamy sauce, use a combination of half-and-half instead of milk and cream.
  • Adjust seasoning to taste.
  • Leftovers can be reheated in the oven to retain crispness.
