Preheat the air fryer to 400°F. Ensure the air fryer is ready to cook for even, crispy results.
In a large bowl, whisk together the avocado oil, maple syrup, garlic powder, salt, and pepper until well combined.
Toss the pork belly pieces in the oil mixture until each piece is evenly coated with the seasoning.
Arrange the pork belly pieces in a single layer in the air fryer basket, ensuring they are not overcrowded for optimal air circulation.
