Partially freeze the beef: Place the meat in the freezer for 45–60 minutes until firm but not rock hard.
This makes thin slicing much easier.
Trim and slice: Remove all visible fat, which can turn rancid during storage. Slice against the grain for a tender bite or with the grain for a chewier texture. Aim for 1/8 to 1/4 inch thick slices.
Pat dry: Use paper towels to blot excess moisture.
Drier surfaces mean faster, more even dehydrating.
Mix the dry rub: Combine salt, pepper, smoked paprika, garlic powder, onion powder, and optional red pepper flakes and sugar in a small bowl.
Season thoroughly: In a large bowl, toss the beef slices with the dry rub, coating both sides. If using Worcestershire or soy, brush a very light layer on the meat first so the spices adhere. Don’t soak—this is not a marinade.
Preheat the air fryer: Set to 175–180°F (80–82°C) if your model goes that low.
If not, use the lowest setting (often 200°F/93°C) and prop the lid/door slightly ajar with a heat-safe utensil to increase airflow and reduce heat buildup.
Arrange the slices: Lightly oil the racks or basket. Lay strips in a single layer without overlap. Work in batches if needed.
For basket models, consider a perforated parchment liner to reduce sticking, but keep airflow in mind.
Dry the jerky: Cook for 2–3 hours at 175–180°F, flipping every 45–60 minutes and rotating racks if your unit has multiple levels. If your lowest temp is 200°F, start checking at 1.5 hours and reduce time as needed.
Check for doneness: Jerky is ready when it’s dry to the touch, darker in color, and bends without snapping. When bent, it should crack slightly but not break clean through.
If it feels damp or spongy, keep drying in 15-minute increments.
Cool and condition: Let jerky cool completely on a rack. Then place it loosely in a clean jar or bag at room temperature for 24 hours, opening once to release excess moisture. This “conditioning” helps equalize moisture so pieces store safely and consistently.
Store properly: Transfer to airtight containers.
