Ingredients

  • 4 large russet potatoes thinly sliced
  • 2 cups shredded cheddar cheese
  • 1 cup grated Parmesan cheese
  • 3 cups heavy cream
  • 3 cloves garlic minced
  • 1 teaspoon salt
  • 0.5 teaspoon black pepper
  • 0.5 teaspoon paprika
  • 1 tablespoon olive oil for greasing the baking dish
  • 1 tablespoon fresh thyme leaves

Instructions

  • Start by washing and peeling your russet potatoes. Using a mandoline slicer or a sharp knife, slice them into thin, uniform rounds—about 1/8 inch thick.
  • In a medium bowl, whisk together the heavy cream, minced garlic, salt, black pepper, and paprika to create the cream sauce.
  • Grease your baking dish with olive oil. Arrange a single layer of potato slices on the bottom, then sprinkle with a mix of cheddar and Parmesan cheese and fresh thyme leaves. Pour some cream sauce over the layer. Repeat layers ending with cheese on top.
  • Cover the dish tightly with aluminum foil and bake in a preheated oven at 350°F (175°C) for about 60 minutes.
  • Remove the foil and bake uncovered for another 15-20 minutes until the top is golden brown and bubbly. Optionally broil for 2-3 minutes for extra crispiness, watching carefully.
  • Let the gratin rest for 10 minutes before serving warm as a decadent side dish.

Equipment

  • Mandoline slicer or sharp knife
  • Large Mixing Bowl
  • 9x13-inch baking dish
  • Whisk
  • Aluminum foil
  • Oven mitts

Notes

  • For a creamier texture, swap russet potatoes with Yukon Golds.
  • Try different cheeses like Gruyère or mozzarella for varied flavors.
  • Store leftovers in an airtight container in the fridge for up to 4 days and reheat covered in the oven.
