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

  1. Preheat oven to 400°. In a greased 13x9-in. baking dish arrange sweet potato slices in rows; set aside.
  2. 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.
  3. 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. Let rest 10 minutes before serving.
