For the best texture, use pork belly with a balance of meat and fat and be sure not to overcrowd the pan, air fryer basket, or skillet so that the bites render fat and crisp instead of steaming. Leftover pork belly bites can be cooled completely and stored in an airtight container in the refrigerator for up to 5 days or in the freezer for up to 2 months. Reheat in a 350°F oven or air fryer until hot and crisp, avoiding the microwave if you want to preserve the crunch. Serve as a stand alone snack, on top of salads, with roasted low carb vegetables, or alongside eggs for a hearty keto breakfast.
