Ingredients

  • 4 large russet potatoes, peeled and thinly sliced

  • 2 tablespoons unsalted butter

  • 1 small onion, finely chopped

  • 2 cloves garlic, minced

  • 1 1/2 cups heavy cream

  • 1 cup whole milk

  • 1 teaspoon salt

  • 1/2 teaspoon black pepper

  • 1/2 teaspoon dried thyme

  • 1/4 teaspoon ground nutmeg (optional)

  • 2 cups shredded sharp cheddar cheese

  • 1/2 cup grated Parmesan cheese

  • Fresh parsley or thyme for garnish (optional)

Instructions

  • Preheat the oven: Preheat to 375°F (190°C) and grease a 9×13-inch baking dish with butter or cooking spray.

  • Prepare the sauce: In a saucepan, melt butter over medium heat. Add onion and cook for 3-4 minutes, then add garlic and cook for 30 seconds.

  • Make the creamy sauce: Stir in cream, milk, salt, pepper, thyme, and nutmeg (if using). Simmer for 5-7 minutes until it slightly thickens.

  • Layer the potatoes: Arrange a layer of sliced potatoes in the baking dish. Pour some sauce over the potatoes and sprinkle with cheddar and Parmesan. Repeat the layering process until all ingredients are used.

  • Top with cheese: After the final layer of potatoes, top with remaining cheddar and Parmesan cheese.

  • Bake the potatoes: Cover with foil and bake for 45 minutes. Remove foil and bake for an additional 20-25 minutes, until golden and bubbly.

  • Let it rest: Allow the dish to rest for 10 minutes before serving to help thicken the sauce.

  • Serve: Garnish with fresh parsley or thyme and serve warm.

Notes

You can mix in different cheeses such as Gruyère or mozzarella for a richer flavor.Use Yukon Gold potatoes for a creamier texture or red potatoes for a firmer bite.
