Description

This Potatoes Au Gratin is the king of comfort food, featuring layers of thinly sliced potatoes, a silky garlic-herb cream sauce, and a perfectly bubbly, golden-brown cheese crust. It is a versatile dish that works just as well for a fancy holiday dinner as it does for a cozy Tuesday night at home.

Ingredients

Scale
  • 3 pounds Yukon Gold or Russet potatoes, sliced 1/8-inch thick
  • 4 cloves garlic, minced
  • 1 small yellow onion, sliced into paper-thin rings
  • 1 tablespoon fresh thyme leaves
  • 1 teaspoon chopped fresh rosemary
  • 2 cups heavy cream
  • 1 cup whole milk
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups shredded Gruyère cheese
  • 1 cup sharp Cheddar cheese
  • 1.5 teaspoons salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/4 teaspoon nutmeg

Instructions

  1. Prepare the Potatoes: Wash potatoes and use a sharp knife or mandoline to cut into 1/8-inch thick rounds.
  2. Make the Garlic Herb Roux: Melt butter in a saucepan over medium heat. Sauté garlic and onions for 3 minutes until soft. Whisk in flour for 1 minute to create a roux.
  3. Create the Cream Sauce: Slowly whisk in milk and heavy cream. Add salt, pepper, nutmeg, thyme, and rosemary. Simmer for 5 minutes until thickened, then stir in 1 cup of Gruyère until melted.
  4. Assemble the Dish: Grease a 9×13 inch baking dish. Layer one-third of the potatoes, then one-third of the sauce. Repeat layers until finished.
  5. Bake: Top with remaining Gruyère and Cheddar. Cover tightly with foil and bake at 375°F for 40 minutes.
  6. Finish and Rest: Remove foil and bake for another 20-30 minutes until bubbly and brown. Let rest before serving.

Notes

For the best texture, resist the urge to slice potatoes too thick or they will stay crunchy. You can assemble the entire dish a day in advance and store it in the fridge until ready to bake. If reheating, use the oven at 325°F to keep the cheese from getting oily.
