To reheat it, you can use either microwave, air fryer, or oven bake. For Microwave: Use high setting for 60 seconds. The only downside to using a microwave is that it makes your corn dog soggy. For Air Fryer: Adjust the setting to 400 F / 200 C and heat it for 5 minutes. For Oven Bake: Baked for 10-15 minutes in 400 F.
