Ingredients:
- 4 large Yukon Gold or Russet potatoes, thinly sliced
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- 1/2 cup grated Parmesan cheese
- 2 cups heavy cream
- 1 cup whole milk
- 3 cloves garlic, minced
- 1 teaspoon fresh thyme (optional)
- Salt and pepper to taste
- 2 tablespoons unsalted butter
- 1 tablespoon flour
Instructions:
- Preheat the oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
- Prepare the cheese sauce: In a medium saucepan, melt the butter over medium heat. Stir in the minced garlic and cook for 1-2 minutes until fragrant. Add the flour, whisking constantly to create a roux. Slowly whisk in the heavy cream and milk, stirring until the mixture begins to thicken.
- Add the cheeses: Remove the saucepan from heat and stir in 1 1/2 cups of cheddar, 1/2 cup of Gruyère, and half of the Parmesan. Season with thyme (if using), salt, and pepper. Continue stirring until the cheese is fully melted and the sauce is smooth.
- Layer the potatoes: Spread a third of the sliced potatoes evenly in the prepared baking dish. Pour a third of the cheese sauce over the potatoes. Repeat this process for two more layers, finishing with the remaining cheese sauce on top.
- Top with cheese: Sprinkle the remaining cheddar, Gruyère, and Parmesan cheeses evenly over the top of the gratin.
- Bake: Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly, and the potatoes are tender when pierced with a fork.
- Serve: Let the gratin cool for 5-10 minutes before serving to allow the sauce to set.
This Extra-Cheesy Potato Gratin is rich, creamy, and decadent—an irresistible dish for any cheese lover!
