Trim the beef: Use a sharp knife to remove as much surface fat and silverskin as possible. Fat doesn’t dry well and can go rancid during storage.
Partially freeze for easy slicing: Place the beef in the freezer for 45–60 minutes.
You want it firm, not rock solid. This helps you cut even, thick slices.
Slice against the grain for tender chew: Cut strips about 1/4 to 3/8 inch thick. Thicker slices give that hearty, thick cut jerky feel while still drying through.
For more chew, slice with the grain.
Mix the marinade: In a bowl, combine soy sauce, Worcestershire, brown sugar or maple, salt, pepper, garlic powder, onion powder, smoked paprika, red pepper flakes, vinegar, and liquid smoke if using.
Marinate: Add beef strips to a bag or dish. Pour in the marinade, press out air, and massage to coat. Refrigerate at least 6 hours, ideally 12–18 hours for full flavor.
Rotate once or twice.
Prep the air fryer: Line the bottom tray with parchment or foil and poke holes for airflow. Lightly oil the air fryer grate or use a perforated parchment liner to prevent sticking.
Blot excess marinade: Lay strips on paper towels and pat dry. Removing surface moisture helps the jerky dry faster and prevents steaming.
Arrange in a single layer: Place strips on the air fryer rack with space between pieces.
Avoid overlapping.
Set the temperature low: Air fry at 175–185°F (80–85°C) if your model allows. If the lowest setting is 200°F (93°C), use that and check earlier. You’re aiming to dehydrate, not cook.
Dry the jerky: Cook for 2 to 3.5 hours, flipping every 30–45 minutes.
Timing depends on thickness and your air fryer. Thicker cuts often land around 3 hours.
Test for doneness: A finished piece should be dry to the touch, darkened, and flexible. Bend it; it should crack slightly along the surface but not snap cleanly.
If it’s wet or spongy, continue in 15–20 minute increments.
Optional safety step: For food safety, you can preheat the marinated slices in a 275°F (135°C) oven for 10 minutes to quickly bring internal temp above 160°F before dehydrating. Then transfer to the air fryer to finish drying.
Cool before storing: Let jerky cool completely on a rack. This prevents condensation in storage containers.
