How to Make Beef Jerky Safely at Home (2026)

The one rule: the meat must hit a safe internal temperature

Drying concentrates meat and pulls out the moisture that spoilage needs, but it does not, on its own, kill E. coli O157:H7 or Salmonella. USDA FSIS is explicit that a dehydrator will not heat the meat to a lethal temperature before the jerky dries, because evaporative cooling keeps the surface cooler than the air, and drying can actually make some bacteria more heat-resistant. So the safe process adds a real heat treatment. You have two ways to do it:

• Pre-heat: bring the marinated strips to 160F internal (beef) or 165F (poultry) first, by steaming or roasting them, then dry at 130F to 140F. This is the USDA-preferred order.
• Post-heat: dry the jerky first, then finish it in a 275F oven until the meat reaches 160F internal (about 10 minutes). This is the easier retrofit if your dehydrator cannot do the heating.

Either way, the number that matters is the meat's internal temperature, checked with a thermometer, not the dehydrator's air setting. A machine that runs at 160F air is not the same as meat at 160F internal, which is exactly the mistake to avoid.

Cure or no cure?

For jerky you will keep in the fridge and eat within a week or two, a curing salt is optional; the heat step is what makes it safe to eat. For jerky you want shelf-stable at room temperature, a nitrite cure (often sold as Prague Powder #1 or pink curing salt) adds a real margin of safety against bacteria during the low-and-slow drying, and it gives that classic cured flavor and color. If you use one, weigh it to the meat per the package, never eyeball it.

Owners who cure note the box directions differ by prep, ground versus whole muscle:

If you look at the instructions provided with the box, they give different instructions for ground (water+rub+cure) vs muscle (rub+cure). For muscle you sprinkle the dry rub liberally using the provided shaker on both sides of the meat. It’s not a marinade like what you’re thinking

Slicing and marinade

Start with a lean cut, eye of round, top round, or flank, and trim every bit of fat you can, because fat goes rancid and shortens shelf life. Slice thin and even, about 1/8 to 1/4 inch. Slicing with the grain gives a chewier chew; against the grain is more tender. Partially freezing the meat for an hour makes clean, even slices far easier, and a jerky slicer makes uniform strips that dry at the same rate.

A shortcut worth knowing for both the cut and the slicing:

Look at a Hispanic market for various lean cuts that are already thinly sliced, my favorite is one called Cecina.

Marinate 6 to 24 hours in the fridge (never on the counter). A basic marinade is soy sauce, Worcestershire, and your spices; the salt in it also helps preservation. Pat the strips dry before they go on the trays so they dry instead of steam.

Your first batch, step by step

• Trim and freeze the lean beef for about an hour, then slice 1/8 to 1/4 inch, with or against the grain.
• Marinate 6 to 24 hours in the fridge.
• Do the heat step. Preferred: bring the strips to 160F internal by steaming or a hot oven, then dry. Or dry first and post-heat (below).
• Lay strips in a single layer, not touching, and dry at 160F until leathery: it should bend and crack but not snap, with no soft or wet spots, usually 4 to 8 hours depending on thickness.
• If you did not pre-heat, finish the dried jerky in a 275F oven until it reaches 160F internal, about 10 minutes, checked with a thermometer.
• Cool completely, then store.

Storing jerky (and how long it lasts)

Let jerky cool fully, then condition it: pack it loosely in a jar for a day and shake it; if moisture beads on the glass, it was under-dried, so dry it a little more. Properly dried, unrefrigerated homemade jerky keeps about 1 to 2 months in an airtight container, longer in the fridge or freezer. If you did not use a cure, treat it as a fridge product for best safety. A vacuum sealer and an oxygen absorber extend that; see our take on vacuum sealers.

Under-drying is the classic beginner mistake, and it shows up fast:

I’ve made jerky this way and it’s very difficult to get all the moisture out. Mine molded within a week. Dehydrator is the way to go!

So what should you buy?

You need a dehydrator that holds a steady 160F with good airflow, a meat thermometer to verify the internal-temperature step (the single most important tool here), and, optionally, a slicer for even strips. The picks below cover all three.

If you are on the fence, the payoff tends to win beginners over quickly:

Ah, just found your post. I'm thinking of making my own beef jerky in a couple of months, (I'm currently into foie gras and sausages, still learning) and came across this little beginners pearl. Thanks!
