To make beef jerky at home safely, heat the meat to 160°F before drying it at 130°F to 140°F.
Most people skip the most important step when making jerky at home. They slice the meat, marinate it, and toss it straight into the dehydrator. That works for texture, but it can leave bacteria alive in the finished snack.
The reliable way to make beef jerky at home follows USDA food safety guidance: get the meat to a safe internal temperature first, then dry it at controlled low heat.
Start with Lean Meat and Safe Handling
Trim all visible fat before slicing. Fat shortens shelf life and can turn rancid during storage, so lean cuts like top round or flank steak are the best starting point.
Keep the meat refrigerated at 40°F or below from the moment you buy it until you start prepping. If the meat is frozen, defrost it in the refrigerator — never on the counter.
- Slice meat evenly so all strips dry at the same rate.
- Thin strips dry faster; exact thickness depends on your recipe and equipment.
- Marinate in the refrigerator, not at room temperature.
- Never reuse marinade that has touched raw meat.
Pre-Heat the Meat Before Drying
This is the step most home recipes leave out. Drying alone does not make jerky safe — the meat must reach a lethal temperature to kill pathogens first.
Pre-heat beef to an internal temperature of 160°F and poultry to 165°F before you start dehydrating.
Do not rely on the dehydrator to do both jobs. The dehydrator should hold the drying temperature, not replace the pre-heat step. Pre-cook the meat in an oven or on a stovetop until it hits the target temperature, then transfer it to the dehydrator.
Dry at the Right Temperature, Store the Right Way
After pre-heating, set your dehydrator to hold between 130°F and 140°F for the entire drying process. If you use an oven or smoker, the same temperature rules apply.
Drying time varies by thickness and equipment, so check regularly rather than trusting a fixed clock. The jerky is done when it bends and cracks but does not snap.
Store finished jerky in an airtight container.
Freezing jerky extends its shelf life further, though freezing does not kill all microbes — it only stops their growth. If you prefer equipment designed for even drying, browse our roundup of the best beef jerky makers before you buy.
FAQs
Can I skip the pre-heating step if my dehydrator runs hot?
Even a hot dehydrator is not a reliable substitute for pre-heating. The USDA guidelines recommend pre-heating meat to 160°F for beef or 165°F for poultry before drying, and a meat thermometer is the only way to confirm the meat reached that temperature.
How long does homemade beef jerky last?
Refrigeration can extend that window slightly, and freezing stops microbial growth entirely. However, freezing does not kill microbes already present, so the safety of your jerky still depends on reaching the correct pre-heat temperature before drying.
Why does my jerky turn out hard or brittle?
Jerky becomes brittle when it is overdried or sliced too thin. Strips that are cut unevenly also dry at different rates, leaving some pieces tough while others are still moist. Slice meat evenly and check the jerky frequently during the last hour of drying — it should bend and crack but not snap cleanly in half.
