These easy scalloped potatoes come together quickly and are rich and decadent.
- 2 tablespoons unsalted butter
- 1 small onion (minced)
- 2 garlic cloves (minced)
- 3 cups heavy cream
- 1 cup whole milk
- 4 sprigs fresh thyme
- 2 bay leaves
- 2 teaspoons salt
- ½ teaspoon ground black pepper
- 4 pounds russet potatoes (peeled and cut into 1/8-inch-thick slices)
- 1½ cups shredded cheddar cheese
- Heat oven to 400 degrees F.
- Meanwhile, melt butter in large Dutch oven (or large, heavy-bottomed saucepan) over medium-high heat until foaming subsides, about 1 minute. Add onion and saute until it turns soft and begins to brown, about 4 minutes. Add garlic and saute until fragrant, about 30 seconds. Add cream, milk, thyme, bay leaves, salt, pepper, and potatoes and bring to a simmer. Cover, adjusting heat as necessary to maintain a light simmer, and cook until potatoes are almost tender (paring knife can be slipped into and out of center of potato slice with some resistance), about 15 minutes, gently stirring occasionally to ensure the potatoes don't stick to the bottom of the pot.
- Remove and discard thyme sprigs and bay leaves. Transfer potato mixture to a 3-quart baking dish and sprinkle with cheese. Bake until the cream has thickened and is bubbling around sides and the top is golden brown, about 30 minutes. Allow to sit for 10 minutes before serving.
