Ingredients

3 pounds medium sweet potatoes, peeled and sliced 1/8-in. thick
2 tablespoons butter
1/2 medium onion, finely chopped
3 garlic cloves, minced
2 tablespoons all-purpose flour
1 cup whole milk
3/4 cup heavy whipping cream
1 teaspoon salt
1/4 teaspoon pepper
1/8 teaspoon cayenne pepper
1/8 teaspoon ground cinnamon
1/2 cup shredded Parmesan cheese
2 cups shredded Gruyere cheese, divided

Directions

Preheat oven to 400°. In a greased 13x9-in. baking dish arrange sweet potato slices in rows; set aside.
In a small saucepan, melt butter over medium heat. Add onion; cook until tender, 4-5 minutes. Add garlic; cook one additional minute longer. Stir in flour until blended; gradually whisk in milk and cream. Bring to a boil, stirring constantly; cook and stir 3-4 minutes or until thickened. Stir in salt, pepper, cayenne, cinnamon, Parmesan and 1 cup Gruyere. Remove from heat; stir until cheese is melted.
Pour cheese sauce over sweet potatoes; sprinkle remaining 1 cup Gruyere on top. Bake, covered, 30-35 minutes. Remove covering; bake until cheese is bubbly and golden brown on top, 10-15 minutes longer.
