1. Trim the beef: Start by trimming any excess fat from the beef. This helps prevent spoilage and ensures even drying.

2. Slice beef for jerky: For best results, slice the beef against the grain into thin strips, about 1/4 inch thick. Uniform slices ensure even cooking and texture.

Marinating the Beef:

3. Prepare the beef jerky marinade: In a mixing bowl, combine soy sauce, Worcestershire sauce, honey, garlic powder, onion powder, smoked paprika, black pepper, cayenne pepper, and red pepper flakes (if using).

4. Marinate beef: Place the beef strips into a ziplock bag or shallow dish. Pour the marinade over the beef, ensuring all pieces are well-coated.

5. Overnight marination: Seal the bag or cover the dish, and let it marinate in the refrigerator for at least 4 hours, preferably overnight, for optimal flavor.

Air Frying the Jerky:

6. Arrange the beef: Lay the marinated beef strips in a single layer in the air fryer basket. Avoid overlapping to ensure even cooking.

7. Air fryer settings: Set the air fryer to 160°F (71°C) and cook for 1-2 hours. Check the jerky halfway through and rotate the strips for even drying.
