Sweet Potato Gratin

Step 1

Preheat the oven to 400 degrees F (200 degrees C). Grease a baking dish with cooking spray.

Step 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.

Step 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.

Step 4

Bake in the preheated oven until golden brown and bubbly, about 30 minutes.
