Begin by cutting the pork belly into bite-sized cubes, ensuring uniformity for even cooking.
In a mixing bowl, combine soy sauce, hoisin sauce, olive oil, Chinese five-spice powder, garlic powder, ginger powder, salt, and black pepper.
Add the pork belly cubes to the marinade, ensuring each piece is thoroughly coated. Allow the pork to marinate for a minimum of 30 minutes, or for a richer flavor, refrigerate overnight.
Preheat the air fryer to 400°F (200°C) for approximately 5 minutes.
Arrange the marinated pork belly cubes in a single layer in the air fryer basket, avoiding overcrowding to promote even cooking.
Air fry the pork belly for 15-20 minutes, flipping the cubes halfway through the cooking process. The goal is to achieve a golden brown and crispy exterior.
Once cooked to perfection, carefully remove the pork belly bites from the air fryer, allowing any excess oil to drain on a paper towel.
Garnish the pork belly bites with chopped green onions and sesame seeds for an added burst of freshness and texture.
Present the Air Fryer Pork Belly Bites as a delightful appetizer or snack, celebrating the harmonious blend of flavors and the satisfying crispiness of the exterior.
