Dauphinoise (potatoes au gratin)
Elevate your potato skills by making this classic French dish.
Ingredients:
- 2 1/2 pounds starchy potatoes (Idaho)
- 2 tablespoons unsalted butter (room temperature)
- 1 1/2 cups heavy cream
- 1/2 cup full-fat milk
- 1 teaspoon salt
- 1/4 teaspoon black pepper
- 2 1/2 cups Gruyère cheese
- 2 cloves garlic, minced
- 2 teaspoons thyme leaves
- Peel the potatoes and slice them into 1/4-inch thick slices.
- Rub your baking dish with 2 tablespoons of unsalted butter.
- Preheat your oven to 350°F.
- Arrange the sliced potatoes by stacking them next to each other and filling the center.
- In a measuring cup, stir together the heavy cream, milk, salt, and black pepper. Pour this mixture over the potatoes.
- Top the potatoes with the minced garlic and thyme leaves.
- Cover the dish with parchment paper and bake in the oven for 1 hour, or until the potatoes are soft. I recommend placing the baking dish on a baking sheet to prevent any spills at the bottom of your oven.
- Remove the parchment paper and top the potatoes with the Gruyère cheese. Bake for another 5-10 minutes, or until the top is golden brown. You can also broil the dish for a few minutes.
- Let the dauphinoise rest for 10 minutes before serving.
Note: There is no substitute for Gruyère cheese. If you have leftovers, add a little more milk, cover the dish, and heat it in the oven.
