How to Make Jerky Using a Dehydrator | Custom Dried Beef

For the full breakdown, see our best Dehydrator for Jerky Under $100 guide.

Homemade beef jerky saves money over store-bought, and a dehydrator gives you total control over flavor and texture.

The Essential Step Sequence

Each step matters, and skipping one creates a failure point. Before you start, confirm you have a lean cut (eye of round, top round, or sirloin tip) because fat turns rancid during drying. A partially frozen roast slices much more cleanly than a thawed one—freeze it about 1–2 hours first.

• Slice ⅛ to ¼ inch thick. Cutting across the grain gives tender jerky; cutting with the grain gives chewier strips. Consistency matters for even drying, so use a slicer or a sharp knife.
• Marinate refrigerated 8–24 hours. The Cosori recipe allows as little as 30 minutes, but the Virginia Beef Industry Council recommends overnight. Shake the sealed bag occasionally to coat every strip.
• Pat strips dry before loading them on dehydrator trays. Surface moisture extends drying time and can breed bacteria.
• Arrange in a single layer with space between pieces. Overlapping traps moisture and creates soggy spots that spoil.

Temperature and Time That Actually Works

Modern dehydrator recipes lean toward 160°F because it brings the meat to a safe internal temperature during the drying cycle. The UC ANR safety guidance suggests 145°F–155°F for at least 4 hours, followed by a 275°F oven step.

Whichever temperature you choose, the real measure is the jerky’s feel: it should bend and crack but not snap completely in half. Typical drying times run 4–10 hours depending on thickness, humidity, and your dehydrator model.

Safety Step Everyone Should Take

Dehydrators alone may not kill all pathogens because the drying temperature can hover in a danger zone too long. University of California ANR guidance and the Virginia Beef Industry Council both agree on a post‑dry oven finish: preheat to 275°F, place the dried jerky on a baking sheet, and heat for 10 minutes. This brings beef to 160°F internal temperature, killing bacteria without cooking the jerky further. For poultry jerky, the target is 165°F.

How to Tell It’s Done (And What Ruins It)

Cool a test strip on the counter for a few minutes, then bend it. Done jerky flexes and cracks at the surface but does not snap in half. If it is still soft or tacky, run the dehydrator longer and test again every 30 minutes. Common failures include:

• Too much moisture on strips before drying (always pat dry).
• Overcrowded trays that trap steam (leave finger‑width gaps).
• Fatty meat that smells rancid after a week (stick to lean cuts).
• Stopping too early while the jerky still feels soft (it will mold).

Cool jerky completely before storing it in an airtight container or vacuum bag. Refrigerated, it keeps several months; pantry storage works only if the jerky is very dry and properly salted.
