To Freeze. Place the waffles on a parchment paper-lined baking sheet. Freeze until frozen (about 2 hours). Once the waffles are completely frozen, put them in an airtight freezer-safe container. The waffles will stay good for up to 4 months.
To Reheat. Preheat the oven or toaster oven to 350 degrees F. Bake frozen or refrigerated waffles for 10–15 minutes, or until hot. You can also heat them up in a toaster.
