Ingredients
Scale
Potatoes:

Cheese Sauce:
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 2 garlic cloves, minced
- 1 teaspoon salt
- ½ teaspoon black pepper

Instructions
- Preheat the oven: Preheat the oven to 375°F and lightly grease a 9×13-inch baking dish.
- Prepare the sauce: In a medium saucepan, melt the butter, stir in flour to form a roux, then gradually whisk in milk and cream. Cook until thickened, about 5 minutes. Stir in garlic, salt, pepper, and thyme.
