A comforting and creamy scalloped potatoes recipe featuring nutty Gruyère cheese, perfect for family dinners and busy weeknights.

Ingredients

Scale
  • 2 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 8 ounces Gruyère cheese, shredded
  • 1 ½ cups heavy cream
  • ½ cup milk (whole or 2%)
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves, finely chopped (or ½ teaspoon dried thyme)
  • Pinch of nutmeg, freshly grated
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly butter a 9×13 inch baking dish and set aside.
  2. Peel and slice potatoes about 1/8 inch (3 mm) thick. Rinse slices briefly in cold water to remove excess starch, then pat dry.
  3. In a medium saucepan, melt butter over medium heat. Add minced garlic and cook for about 1 minute until fragrant.
  4. Whisk in flour and stir continuously for 1-2 minutes to cook off raw flour taste.
  5. Slowly add cream and milk while whisking to avoid lumps. Bring to a gentle simmer and cook until sauce thickens enough to coat the back of a spoon, about 4-5 minutes.
  6. Remove from heat and stir in thyme, nutmeg, salt, and pepper. Adjust seasoning as needed.
  7. Gradually stir in Gruyère cheese until melted and smooth.
  8. Arrange a single layer of potato slices in the prepared baking dish. Spoon 1/3 of the cheese sauce over the potatoes and spread gently to cover. Repeat layering two more times, finishing with sauce on top.
  9. Bake uncovered for 50-60 minutes until potatoes are tender and top is golden and bubbling. Tent with foil if top browns too quickly.
  10. Let the scalloped potatoes rest for 10 minutes before serving to thicken and make slicing easier.

Notes

Use a mandoline for uniform potato slices to ensure even cooking. Season each potato layer lightly with salt and pepper for better flavor. For a crispier top, sprinkle extra shredded Gruyère or Parmesan cheese before baking. Avoid covering the dish during baking to get a golden crust; tent with foil if browning too fast. Sauce should be thick to prevent a soupy dish. Dairy-free and gluten-free substitutions are possible but will alter texture and flavor.
