Partially freeze the pork: Place the trimmed pork in the freezer for 45–60 minutes. You want it firm, not rock solid. This makes thin slicing easier and more even.
Slice thinly: Using a sharp knife, slice the pork against the grain into 1/8-inch to 1/4-inch slices.
Thinner slices dry faster and more evenly. Aim for uniform thickness.
Mix the marinade: In a bowl, combine soy sauce, fish sauce, brown sugar, vinegar, Worcestershire, smoked paprika, garlic powder, onion powder, black pepper, red pepper flakes, and sesame oil. Stir until the sugar dissolves.
Marinate: Add pork slices to the marinade and toss to coat.
Cover and refrigerate for at least 4 hours, ideally overnight. Longer marinating means deeper flavor.
Drain and pat dry: Remove pork from the marinade and shake off excess liquid. Pat the slices dry with paper towels. Dry surfaces dehydrate faster and reduce burning.
Preheat the air fryer: Set to 180–200°F (80–93°C) if your model allows.
If the lowest setting is 200°F or higher, use that and monitor closely.
Arrange the slices: Lay pork in a single layer in the basket or on air fryer racks. Do not overlap. Work in batches if needed.
For basket models, use a perforated parchment liner to prevent sticking, leaving plenty of holes for airflow.
Air fry low and slow: Cook at 180–200°F for 45 minutes. Flip or rotate racks, then continue 20–45 more minutes. Total time varies by thickness, air fryer model, and humidity.
Check for doneness: Jerky is ready when it’s firm, dry to the touch, and bends slightly before cracking but doesn’t snap. No visible moisture should squeeze out when pressed.
Optional finish: If you prefer a touch more caramelization, increase the heat to 230°F for 3–5 minutes at the very end.
Watch closely to avoid burning.
Cool completely: Transfer to a wire rack and let cool to room temperature. Cooling allows residual steam to escape, preventing sogginess in storage.
Condition the jerky (recommended): Place cooled jerky loosely in a large jar or container for 24 hours, shaking once or twice. If condensation forms, return jerky to the air fryer at 180°F for 10–15 minutes to dry further.
