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