A comforting and cheesy scalloped potatoes au gratin recipe perfect for Easter or any special occasion, featuring tender potato layers with a golden cheesy crust and a homemade béchamel sauce.

Ingredients

Scale
  • 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 4 tablespoons unsalted butter, plus extra for greasing the dish
  • 3 tablespoons all-purpose flour
  • 2 cups whole milk, warmed
  • 2 cloves garlic, minced
  • 1/4 teaspoon freshly grated nutmeg (optional)
  • 1 cup sharp cheddar cheese, shredded
  • 1 cup Gruyère or Swiss cheese, shredded
  • Salt and freshly ground black pepper, to taste
  • Fresh thyme or parsley for garnish (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Butter your 9×13-inch baking dish generously to prevent sticking and add richness.
  2. Peel and slice the potatoes thinly—about 1/8 inch (3 mm) thick. Rinse the slices under cold water and pat dry with a clean towel to remove excess starch.
  3. In a medium saucepan over medium heat, melt 4 tablespoons of butter. Add the minced garlic and cook for about 1 minute until fragrant but not browned.
  4. Stir in 3 tablespoons of all-purpose flour and whisk continuously for 2-3 minutes to cook out the raw flour taste.
  5. Gradually add 2 cups of warmed whole milk, pouring slowly while whisking to avoid lumps. Keep stirring until the sauce thickens to a creamy consistency, about 5 minutes.
  6. Add 1/4 teaspoon of freshly grated nutmeg, salt, and black pepper to taste. Remove from heat.
  7. Place a layer of potato slices evenly in the buttered baking dish. Pour a third of the béchamel sauce over the potatoes, then sprinkle a third of the shredded cheese (a mix of cheddar and Gruyère). Repeat layering two more times, finishing with cheese on top.
  8. Cover the dish with foil and bake in the preheated oven for 45 minutes.
  9. Remove the foil and bake uncovered for an additional 15-20 minutes, or until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
  10. Let the scalloped potatoes rest for about 10 minutes before serving to set up and meld flavors.

Notes

Use a mandoline for even potato slices or a sharp knife if patient. Butter the baking dish well and consider lining with parchment paper for easier cleanup. Tent foil if the top browns too fast. If sauce is too thick before layering, whisk in a splash of milk to loosen. For extra flavor, add smoked paprika on top before baking. Resting the dish before slicing helps it set and improves texture.
