Yes, hushpuppies can be made ahead of time and reheated in the oven or on a stovetop. To reheat them in the oven, place them on a baking sheet and bake at 350°F for 10-15 minutes, or until heated through. To reheat on the stovetop, place them in a skillet over medium heat and cook for 5-7 minutes, or until heated through and crispy.
