My grandmother always served this sweet potato casserole at Thanksgiving. The puffy marshmallow topping gives the dish a festive look, and spices enhance the sweet potato flavor. —Edna Hoffman, Hebron, Indiana

  • 4 pounds sweet potatoes (about 5 large), peeled and cut into 1-inch pieces
  • 1 cup 2% milk
