Ingredients
Units
Scale
- 2 pounds russet potatoes, peeled and thinly sliced
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 2 cups shredded sharp cheddar cheese
- 1/2 teaspoon garlic powder
- 1/4 teaspoon onion powder
- Salt and black pepper, to taste
- 1/4 cup grated Parmesan cheese
- Fresh parsley, chopped (optional, for garnish)
Instructions
- Preheat oven to 375°F (190°C) and grease a 9×13-inch baking dish.
- In a medium saucepan, melt butter over medium heat. Stir in flour and cook for 1 minute to make a roux.
- Gradually whisk in milk and cream, cooking until the mixture thickens, about 3-5 minutes.
- Stir in garlic powder, onion powder, salt, pepper, and cheddar cheese. Cook until cheese is melted and sauce is smooth.
- Layer half of the sliced potatoes in the prepared dish. Pour over half the cheese sauce.
- Repeat with remaining potatoes and sauce. Sprinkle Parmesan cheese over the top.
- Cover with foil and bake for 45 minutes. Remove foil and bake an additional 20-25 minutes until golden and bubbly.
- Let cool slightly before serving. Garnish with chopped parsley if desired.
Notes
- Use a mandoline slicer for evenly thin potato slices.
- Yukon Gold potatoes can be used as a substitute for russet potatoes.
- You can add a pinch of nutmeg to the sauce for extra depth.
