Scalloped Potatoes au Gratin


  • Author: kelsey nixon
  • Yield: 6 servings 1x

Ingredients

Scale
  • 1 tablespoon unsalted butter
  • 1 yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 1 1/2 cups heavy cream
  • 1/2 cup low-sodium chicken broth
  • 2 teaspoons fresh thyme leaves
  • 1 1/2 teaspoon kosher salt
  • 1/2 teaspoon ground black pepper
  • 2 pounds russet potatoes, peeled and sliced into 1/8-inch slices
  • 1/2 cup shredded Cheddar
  • 1/2 cup shredded gruyere cheese

Instructions

Preheat the oven to 375 degrees F. Melt the butter in a large pot over medium-high heat. Add the onions and saute until softened and beginning to brown. Add the garlic and continue cooking 1 minute longer. Stir in the cream, broth and thyme, and season with the salt and pepper. Add the potatoes and bring to a simmer. Continue cooking until the potatoes are fork-tender, 10 to 15 minutes. 

Transfer the potatoes and cream to a shallow baking dish. Sprinkle the cheeses evenly over the potatoes. Bake until bubbly and the surface begins to brown, 15 to 20 minutes. Let sit 10 minutes before serving.
