That subtle bend in a strip of jerky without a clean snap isn’t a sign it’s almost ready—it’s the hallmark of under-drying. Many mistake this pliability for ’nearly there’, but it means moisture remains trapped inside. The times and temperatures detailed here are specifically calculated to push every batch of UK beef past that deceptive point to achieve both safety and the right texture.
Many US recipes quote drying times that run short for a UK kitchen, because they are written for different dehydrators, climates and cuts. Following them blindly leads to jerky that isn’t just subpar; it’s potentially unsafe because dehydrators alone don’t get hot enough to eliminate pathogens.
This guide covers the UK-adjusted drying framework and the non-negotiable thermal step that ensures safety.
The Critical Safety Step Often Overlooked
Dehydrators operate at temperatures around 60–70°C, which is ideal for drying but insufficient to reliably destroy bacteria like Salmonella and E. coli. The crucial, often-missed step is a post-drying oven bake. After the dehydrator has done its work, the jerky should go into a preheated oven for a short bake: around 10 minutes at roughly 135–150°C is the usual advice, and a probe thermometer should read about 71°C in the thickest strip.
This thermal treatment is the definitive safety measure. It firms the texture slightly but, more importantly, guarantees the jerky is safe to eat. Skipping it because a guide didn’t mention it is a common reason batches fail safety checks. Making this oven step a routine part of your process transforms uncertain results into reliably shelf-stable jerky.
Drying Times for UK Beef
For jerky made in a dehydrator set to 60°C, expect these timeframes:

- 5mm strips: 4–6 hours
- 8mm strips: 6–8 hours
These are starting estimates. The final time depends on your specific dehydrator’s airflow, the fat content of the beef, and your kitchen’s humidity. Budget dehydrator models often require times at the upper end of these ranges, especially with thicker strips.
Resist the temptation to open the dehydrator door to check progress. Each time you do, heat escapes and the total drying time stretches. Trust the timer and only check when the initial window has passed.
Using an oven on its lowest setting is possible but less consistent. It demands more frequent temperature checks and isn’t as suitable for overnight drying.
Choosing the Right Equipment
The right tools simplify the process and improve consistency.
Digital Scale Accurate weighing is fundamental for correct marinade ratios. The Salter 1036 Digital Kitchen Scale (paid link) is a 5kg scale with tare. Its listing does not state 0.1g, and the platform is small. The Etekcity EK9000 Food Kitchen Scale (paid link) is the one whose title states 0.1g, with a larger platform. Stock on that listing was not confirmed on this check.

Meat Thermometer Essential for verifying the oven step reaches a safe core temperature. The ThermoPro TP516 Instant Read Meat Thermometer (paid link) is a spot-check with a 12cm probe, which is what a short bake needs. A leave-in Bluetooth thermometer is unnecessary for a ten-minute process.

Dehydrator The Excalibur 5 Tray Stackable Food Dehydrator (paid link) is the larger unit. Some users report noise and durability issues. The Aigostar 5 Tier Food Dehydrator (paid link) is 240W, with a 35–70°C range and a 99-hour timer. It is the budget option; thicker cuts can dry unevenly.

Pitfalls That Can Ruin a Batch
Success hinges on avoiding a few common errors.
Inconsistent Slicing and Weighing Using volume measures for marinades instead of a digital scale leads to uneven flavour and curing. Consistent strip thickness is equally important for even drying.
Omitting the Oven Bake This is the safety-critical step. Skipping it is a mistake you may not notice until too late. The ten-minute bake is a simple, non-negotiable safeguard.
Frequent Checking Peeking inside the dehydrator significantly extends drying time. Use the machine’s viewing window if it has one, and rely on the timer as your primary guide.
Frequently Asked Questions
Is it possible to make jerky using just an oven?
Yes, but it requires careful temperature management. Set your oven to its lowest stable setting and expect it to take many hours, usually longer than a dehydrator, and longer again for thicker cuts. The short safety bake still applies afterwards. A dehydrator is far more efficient for anyone making jerky regularly.
How can I tell if the jerky is dry enough?
Jerky should be dry to the touch and pliable. It should bend without snapping cleanly, but it should not feel soft, sticky, or damp. If there’s any tackiness or noticeable give, it needs more time in the dehydrator.
Can I use the same dehydrator for making biltong?
Biltong and jerky require different processes. Biltong is air-dried at cool room temperatures, while dehydrators apply heat. Using a dehydrator will cook the meat, producing a result closer to jerky than traditional biltong. A dedicated biltong box is the appropriate tool for that craft.
Drying Time Reference
| Factor | Condition | Effect on Drying Time |
|---|---|---|
| Strip Thickness | 5mm | 4–6 hours at 60°C |
| Strip Thickness | 8mm | 6–8 hours at 60°C |
| Method | Oven on its lowest setting | Add several hours |
| Safety Step | Short hot oven bake | About 10 minutes (mandatory) |
| Ambient Humidity | High | Adds time |
| Dehydrator Door | Opened during cycle | Adds time with every check |
Final Adjustments and Next Steps
The provided drying times are your baseline. You’ll likely need to adjust them based on your machine’s performance and the thickness of your slices. Treat the first batch as a calibration run, noting how your specific setup performs.
Once you’ve dialled in your process, the results are consistent and safe. The key is recognising that UK kitchens often need more time than a US recipe suggests, and that the final oven step is essential.
