Using kitchen shears, cut the pork belly slices into uniform 1½-inch pieces.
1 pound pork belly
In a medium bowl, stir together the ground ginger, garlic salt, brown sugar, and hoisin sauce until well combined. Add the pork belly pieces and toss to coat evenly.
½ teaspoon ground ginger, 1 teaspoon garlic salt, 1 Tablespoon brown sugar, ½ cup hoisin sauce
Arrange the pork belly in a single layer in the air fryer basket, making sure the pieces are not overlapping.
Cook at 385°F for 12–15 minutes, or until caramelized and lightly crispy on the edges.
Serve with additional hoisin sauce, sliced green onions, and sesame seeds, if desired.
Depending on the size of your air fryer, you may need to cook in batches to keep the pork belly in a single layer.
