While hush puppies are best enjoyed fresh, leftovers can be refrigerated in an airtight container for up to 2 days or frozen for up to 3 months. To freeze, start by letting the cooked hush puppies cool completely at room temperature. Once cool, arrange them in a single layer on a baking sheet, ensuring they don't touch, and then place the sheet in the freezer for a few hours until solid. After they're frozen, transfer the hush puppies to a freezer-safe bag or container, squeezing out as much air as possible, and freeze for up to 3 months. When you're ready to enjoy them, reheat the hush puppies directly from the freezer in 300°F-oven.
