There’s no single magic number, because drying time follows the meat, not the timer. But the window is tight and predictable once you fix the two things that decide it: how thick you sliced, and how hot you’re running. Nail those and everything else is just fine-tuning.
That’s worth saying plainly up front, because half the frustration with homemade jerky comes from treating a recipe’s “dry for 5 hours” as gospel. Your kitchen isn’t the recipe writer’s kitchen; your slices, your machine, and today’s humidity are all different. The charts below give you the right ballpark, and the doneness test at the end gives you the real answer.
Time by slice thickness
Lean beef, single layer, at 160°F. This is the range to plan your afternoon around, and you can see how quickly thickness swings it.
| Slice | Time | Doneness |
|---|---|---|
| 1/8" | 2-3 h | Snappy, cracker-crisp |
| 1/4" | 4-5 h | Bend & crack (classic) |
| 3/8" | 6-7 h | Chewy, jaw-work |
Run your exact batch
Your meat, thickness and temperature → the drying time and a safe kill-step check, on one screen.
Open Time & TempTime by meat
Same 1/4" slice, different meats. Poultry runs hotter to clear its own kill-step; leaner game like deer and elk can take a touch longer even though it’s dry to begin with, because there’s less fat to conduct heat.
| Meat | Temp | Time (1/4") |
|---|---|---|
| Beef (1/4") | 160°F | 4-5 h |
| Venison / deer (1/4") | 160°F | 4-6 h |
| Ground beef (1/4") | 160°F | 4-6 h |
| Turkey / chicken (1/4") | 165°F | 4-6 h |
| Elk / other game (1/4") | 160°F | 4-6 h |
The timer starts the check. The bend test ends it.
What moves the clock
Four things stretch or shrink the drying time, and once you can see them you can control them. None are complicated, they’re just the difference between a batch that finishes on schedule and one that’s still tacky at hour seven.
Thickness
The biggest lever by far. Every extra 1/8" adds hours, because the moisture has farther to travel out of the strip. Uniform slices finish together; uneven ones leave you picking done strips off a half-dry tray for the rest of the afternoon.
Load & airflow
Crowded trays trap the moisture the meat gives off and slow everything down. Lay strips in a single layer with space between them, and if your machine has hot or cold spots, rotate the trays once or twice through the run.
Humidity & weather
A damp kitchen or a rainy day genuinely adds drying time, the drier the air, the faster water leaves the meat. There’s no fixed clock that survives the seasons, which is exactly why the meat, not the timer, tells you when it’s done.
Fat & marinade
Any fat left on the strip slows drying and beads on the surface. Wet, sugary marinades take longer than dry rubs because that surface moisture has to go first, so always pat strips dry before they go on the tray.
The doneness test
This is the only test that actually matters, so trust it over any clock. Pull a strip, let it cool for a minute (warm jerky lies about its texture), then bend it. Done jerky cracks and shows white fibers at the fold but doesn’t break clean through. Too soft and bendy? Give it more time. Snaps in half? A little over, still perfectly good, just slice a hair thicker or pull earlier next batch. After it’s cool, condition it in a jar for a day to even out any last moisture before storing.
