  1. Preheat the oven to 400 degrees F (200 degrees C). Grease a baking dish with cooking spray.
  2. Combine cream, butter, and garlic in a saucepan. Bring to a simmer; remove from heat and mix in parsley, thyme, sage, rosemary, salt, and pepper.
  3. Arrange 1/2 of the sweet potato slices in the prepared baking dish; cover with 1/2 of the Gruyere cheese. Pour cream mixture on top. Arrange remaining sweet potato slices over the cream. Sprinkle remaining cheese on top.
  4. Bake in the preheated oven until golden brown and bubbly, about 30 minutes.


  • Please note that the magazine version uses 3/4 cup each cream and milk instead of 2 cups cream and is baked for an extra 15 minutes.
