Ingredients Method Notes

Ingredients
  

For the sauce
  • 2 cups heavy cream Provides a luscious and velvety sauce; opt for high-quality for best flavor.
  • 3 tablespoons unsalted butter Enhances richness without added salt, perfect for sautéing onions.
  • 1 clove garlic Contributes aromatic flavor; use fresh for the best taste.
  • 1 teaspoon salt Season to taste; adjust less if using salted butter.
  • 1/2 teaspoon black pepper Adds a gentle heat; freshly cracked enhances flavor.
  • 1/8 teaspoon ground nutmeg Optional; adds a warm, spicy undertone, elevating the dish.
  • 2 cups shredded cheese Cheddar is classic, but feel free to mix in Gruyère for extra flavor.
  • 2 tablespoons all-purpose flour Helps thicken the cheese sauce for a perfect texture.
For the potatoes
  • 2 medium russet potatoes Peeled and very thinly sliced; a mandoline is ideal for even slices.
  • 2 medium onions Finely chopped; add sweetness and depth to the sauce; fresh or frozen work well.

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C).
  2. In a skillet over medium heat, melt the butter. Add the chopped onions and sauté until they are soft and translucent.
  3. Stir in the minced garlic and cook for another minute until fragrant.
  4. Sprinkle the flour over the onions and garlic. Mix well and cook for about 1-2 minutes.
  5. Gradually pour in the heavy cream, stirring constantly to avoid lumps. Cook until the mixture thickens slightly.
  6. Add the salt, black pepper, and nutmeg (if using). Remove from heat and stir in the shredded cheese until melted and smooth.
Assembly
  1. In a greased baking dish, layer half of the sliced potatoes. Pour half of the cheese sauce over the top.
  2. Repeat with the remaining potatoes and cheese sauce.
Baking
  1. Cover the dish with foil and bake for 45 minutes.
  2. Remove the foil and bake for an additional 20-25 minutes until the top is golden and bubbly.
  3. Let the dish cool for a few minutes before serving.

Notes

These scalloped potatoes are best served hot and bubbling right out of the oven. They make an excellent side dish for roasted meats, holiday dinners, or as a satisfying main dish. Pair them with a simple green salad for a complete meal. For tips, use a mandoline slicer for perfectly even potato slices, experiment with different cheeses, and for extra crispiness, broil the top for a few minutes after baking.
