  • 11/2 cups heavy cream
  • 2 cloves garlic, finely chopped
  • 1 pound sweet potatoes, peeled and thinly sliced
  • 1 teaspoon dried thyme
  • 11/2 teaspoons salt
  • 3/4 teaspoon black pepper
  • 4 ounces smoked gruyere cheese, shredded


  1. Preheat oven to 400 and lightly spray a 2 quart casserole dish or large baking dish with oil.
  2. In a small sauce pan, gently heat the cream with the garlic over low heat. Remove from heat as soon as it starts to bubble.
  3. Start your layering by arranging your sweet potato slices in an overlapping shingle-type configuration. Then sprinkle the potatoes with a third of the thyme, salt, and pepper. Finally spread a third of the cheese over the sweet potatoes. Repeat this with two more layers, making three layers in all.
  4. Pour your warm, garlic infused cream over the sweet potato, cheese layers.
  5. Cover the dish with foil and bake for 30 minutes. Remove the foil and continue to bake for another 20 minutes or until the cheese is lightly brown, and you can easily slide a sharp knife all the way to the bottom.
  6. Allow the gratin to cool for at least 30 minutes before serving. Watch your guests go crazy.


  • This will probably taste good with cheap shredded Swiss if you don’t want to splurge on the fancy cheese.
