Mashed Potatoes au Gratin combines the creamy, buttery, comfort of mashed potatoes with the golden cheesy crust of au gratin.

Ingredients

  • 4 pounds Yukon gold potatoes, 10 medium size (peeled and diced)
  • 1/2 cup heavy cream or half and half
  • 1/2 cup unsalted butter
  • 5 garlic cloves (measure with your heart)
  • 1 teaspoon sea salt (adjust to taste)
  • 1/2 heaping cup gruyere
  • Thyme (optional)
  • 4 Yukon gold potatoes, thinly sliced
  • 1/2 heaping cup parmesan
  • 1/2 heaping cup gruyere

Directions

  1. 1

    Set your oven to 400°F / 204°C.

  2. 2

    Wash, peel and cut potatoes into equal cubes. Boil for 20-25 minutes until fork tender. Strain the water and return back to the pot.

  3. 3

    Add the heavy cream, butter, salt and garlic to a small saucepan. Heat up over low heat until steaming.

  4. 4

    Lightly spread the mashed potatoes in a medium size, shallow casserole dish with the back of a spoon. I used an oval, 11 inch long dish. Top with a layer of thinly sliced potatoes and gruyere. Cover with foil.

  5. 5

    Bake for 25 minutes. Then, remove the foil and add parmesan on top. Bake for an additional 20 minutes uncovered or until golden and bubbly. Broil in the last 2-3 minutes for extra crisp. Best served hot. Keep covered in the oven until ready to serve.
