How To Make Biltong In Air Fryer Dehydrator | 4-6 Hours

Biltong looks like jerky at first glance, but its texture is different — softer inside, with a tang from vinegar and cracked coriander. Traditional biltong takes days of air-drying in a cool, breezy spot. That works if you have the climate and the patience, but most kitchens don’t.

An air fryer with a dehydrate function can drop that time from days to a single afternoon. The key is getting the temperature low enough to dry without cooking the meat, and managing airflow so the outside doesn’t seal too fast. Here’s how to do it right.

Ingredients and Beef Selection

Start with a lean cut of beef — topside or silverside works well. Excess fat can spoil during drying and shorten shelf life. Slice the beef into strips roughly 1–2 cm thick; thicker pieces need more time and raise the risk of case hardening.

For the marinade, combine brown or malt vinegar with Worcestershire sauce. Crack coriander seeds, salt, and black pepper in a food processor for about ten seconds — whole seeds don’t release as much flavour. Coat the strips, cover, and rest in the fridge for 24 hours.

After marinating, drain the liquid before placing the meat in the air fryer. Any extra moisture will steam the beef rather than dry it, which changes the texture completely.

Why the Air Fryer Works for Biltong

Traditional biltong relies on moving air and low humidity — exactly what an air fryer’s dehydrate setting provides. The main advantage is speed: what takes five to ten days in a traditional setup finishes in a few hours. The trade-off is airflow control. Biltong can suffer from case hardening — the outside dries into a tough shell while the inside stays moist. An air fryer’s fan can be aggressive, so keeping the temperature moderate helps.

• Time savings: Traditional drying takes 5–10 days; an air fryer dehydrator cuts this to 4–6 hours.
• Consistent environment: No need to worry about weather changes or flies. The air fryer keeps temperature and airflow steady.
• Adjustable settings: Many models let you control temperature and fan speed, helping you reduce the risk of case hardening.
• Small batch convenience: You can make just one or two strips without firing up a full dehydrator.

The catch is that not every air fryer dehydrates the same way. Lower-end models may run hot, so always check the actual temperature with an oven thermometer if you’re unsure.

Step-by-Step Recipe for Air Fryer Biltong

Set your air fryer to the dehydrate function at 70°C (160°F) if you want a faster result. An alternative is temperature for 55°C (130°F) for five hours — gentler and less likely to cook the meat. Some manufacturers recommend their own presets; the dehydrator preset temperature on the DNA air fryer guide suggests 55°C for 5 hours for a tender finish.

Place the drained, marinated strips in a single layer on the air fryer tray — no overlapping. Overcrowding blocks airflow and leads to uneven drying. Run the dehydrate cycle for 4 to 6 hours, flipping the strips after about 1.5 to 2.5 hours so both sides dry evenly.

Test doneness by pinching a thick strip after 4 hours. It should feel firm but still have a little give when squeezed. If it still feels too wet, continue in 30-minute increments. Biltong that comes out leathery has been dried too long or at too high a heat — adjust timing next batch.

The table shows that time varies widely based on appliance and meat thickness. The 55°C/5-hour method is a safe starting point if your air fryer has a precise dehydrate preset.

Tips for Perfect Texture and Avoiding Common Mistakes

Getting biltong right on the first try is possible with a few precautions. The most frequent issues are leathery texture and case hardening. Here’s how to prevent both:

1. Use a lean cut of beef. Fat doesn’t dry well and can turn rancid. Trim visible fat before marinating.
2. Don’t skip the 24-hour rest. The vinegar needs time to penetrate and cure the meat. Shorter marinating leads to less flavour and a raw interior.
3. Reduce fan speed if possible. Some air fryers let you lower the fan setting for dehydrating. Slower airflow helps avoid the outer layer drying too fast.
4. Flip at the right interval. Flipping after 1.5–2.5 hours is critical. For thicker strips, flip again near the end.
5. Test texture by feel, not time. Biltong is done when it bends and cracks rather than snaps. If a thin strip snaps cleanly, it may be overdone.

If your first batch turns out leathery, check your drying time and strip thickness. Next time you cut the strips a little thicker or lower the temperature by 5°C and see if the texture improves.

How to Store and Enjoy Your Homemade Biltong

Once your biltong reaches the desired texture, let it cool completely before storage. If it’s still warm, condensation can form and encourage mould. A traditional biltong definition from Greedyferret notes that biltong stored in a paper bag in a cool, dry place keeps for up to two weeks. For longer storage, move it to an airtight container in the fridge, where it can last several weeks.

Slice biltong thinly across the grain for snacking, or cut thicker pieces for a chewier bite. It’s naturally high in protein and low in carbs, which makes it a popular snack for keto and gluten-free diets. Many people enjoy it straight, but it also works sliced over salads or mixed into trail mix.

If you make a large batch, portion it into smaller bags so you only open what you need. Each time you open the bag, you introduce moisture and oxygen, which speeds spoilage.

The Bottom Line

Making biltong in an air fryer dehydrator is faster than the traditional method and requires only a few ingredients and a little patience. Focus on strip thickness, a 24-hour marinade, and a moderate temperature around 55–70°C to avoid drying problems. Flip the meat halfway and test by feel rather than setting a hard timer.

If you’re new to curing meat at home, start with a small batch using topside beef and the 55°C/5-hour method. Your local butcher can confirm the beef is fresh, and your air fryer’s manual will tell you if your dehydrate setting runs at the temperatures listed here.
