The short answer
- How to make beef jerky in a food dehydrator in one line: slice lean beef 1/4 inch thick, marinate 8-24 hours, dry at 135-165°F for about 4-8 hours until it bends and cracks without snapping.
- Safety first: USDA guidance says to bring beef to 160°F at some point in the process, either before drying or by running the dehydrator at that temperature, because a low-heat dehydrator alone may not kill bacteria.
- Lean and cold wins: trim visible fat, then partly freeze the meat for 1-2 hours so it slices evenly.
- Beef loses most of its weight as water when dried, so a pound of raw beef yields only a small bag of jerky, which makes it a high-protein snack you make in bulk.

How to make beef jerky in a food dehydrator: slice lean beef about 1/4 inch thick, marinate it overnight, heat it to a safe 160°F, then dry the strips at a steady temperature for roughly 4-8 hours until they bend and crack without snapping. The dehydrator does the slow, even drying, and the one thing that changes by model is the temperature ceiling, which is why our best food dehydrator picks for jerky list the maximum heat of each unit.
This guide walks through the whole process, from choosing the cut to storing the finished jerky, with the temperatures and times that matter for a high-protein snack.
What is the best cut of beef for jerky?
The best cuts for homemade beef jerky are lean, boneless and cheap: eye of round, top round, bottom round and flank steak. Fat does not dry and goes rancid in storage, so the leaner the cut, the longer the jerky keeps. Brisket and ribeye taste great but carry too much marbling for a dried product.
| Cut | Fat level | Notes |
|---|---|---|
| Eye of round | Very lean | Even grain, easiest to slice uniformly |
| Top round | Lean | Widely available and reasonably priced |
| Bottom round | Lean | Slightly tougher, chewier jerky |
| Flank steak | Lean | Long grain, strong beefy flavor |
Trim every visible strip of fat and silver skin before slicing. A pound of trimmed raw beef is the usual unit for planning marinade quantities.
How do you slice beef for jerky?
Freeze the beef for 1-2 hours until firm but not solid, then slice it into strips about 1/4 inch thick with a sharp knife. Slice with the grain for chewy, traditional jerky or against the grain for a more tender bite. Uniform thickness matters more than the exact number, because thin and thick strips dry at different speeds.
Slice thin, not paper-thin
Strips under 1/8 inch dry fast but turn brittle. Strips over 3/8 inch take much longer and stay moist in the center. A 1/4 inch slice is the sweet spot for most home dehydrators.
What is a good beef jerky marinade for a dehydrator?
A good jerky marinade is salty, a little sweet and acidic, with enough liquid to coat the strips. A reliable starting ratio per pound of beef is 1/2 cup soy sauce, 2 tablespoons Worcestershire sauce, 1 tablespoon brown sugar, 1 teaspoon each of garlic powder, onion powder and black pepper, and a pinch of paprika. Marinate in the refrigerator for 8-24 hours.
Use a zip bag or a covered glass dish so every strip touches the liquid, and turn it once. After marinating, pat the strips with paper towels. Excess surface liquid slows drying and can leave a sticky skin on the finished jerky.
Salt in the marinade is not just flavor: it pulls moisture out and helps preserve the meat. If you cut the soy sauce for a lower-sodium version, expect a shorter shelf life and store it in the freezer.
Do you have to cook beef before dehydrating for jerky?
USDA food-safety guidance says the meat should reach 160°F for beef, either before drying or by drying at a temperature that gets it there. Many home dehydrators run at 135-145°F, a range that can dry meat without reliably killing bacteria such as Salmonella and E. coli. Heating first closes that gap.
You have two safe routes:
- Pre-heat, then dry. Simmer the marinated strips in a pan or bake them on a rack at 275°F until an instant-read thermometer reads 160°F, then move them to the dehydrator at 130-140°F.
- Dry at 160°F or higher. Use a dehydrator whose top setting reaches at least 160°F, and verify with a probe thermometer that the strips themselves hit 160°F.
Know your dehydrator's ceiling
Some units top out at 165°F, others at 176°F or 195°F. If the maximum on your model is close to 160°F, the pre-heat route is the safer default because air temperature inside the box and meat temperature are not the same thing.
What temperature should a dehydrator be for beef jerky?
For beef jerky, set the dehydrator between 135°F and 165°F. Lower temperatures dry gently and give a chewier texture; temperatures near 160°F satisfy the safety target in one step but can harden the outside if the airflow is weak. If you pre-heated to 160°F, 130-140°F is plenty for drying.
| Setting | Typical drying time | Best for |
|---|---|---|
| 130-140°F | 6-12 hours | Strips already heated to 160°F |
| 145-155°F | 5-8 hours | Thin, evenly sliced strips |
| 160-165°F | 4-6 hours | One-step safety and drying |
How long does it take to dehydrate beef jerky?
Most batches take 4-8 hours, and 6-12 hours at the lowest temperatures. Check at the 4-hour mark, then every 30 minutes. Humidity, thickness, the number of trays and how much marinade stayed on the meat all shift the total, so a clock is only a rough guide.
How do you know when jerky is done?
Take one strip out, let it cool for a few minutes, and bend it. Done jerky bends and shows white cracks on the surface but does not snap in two. If it stays soft and pliable with no cracks, dry it another 30-60 minutes. If it snaps cleanly, it is over-dried.
Rotate the trays halfway through, since the trays nearest the fan or heating element finish first. Lay strips in a single layer with a little gap so air can move.
How do you store homemade beef jerky?
Let the jerky cool completely, then blot any fat beads with a paper towel and seal it in an airtight container or zip bag with the air pressed out. Home-dried jerky keeps for a short time at room temperature, longer in the refrigerator and longest in the freezer; USDA and extension guidance gives specific limits, so check them for your recipe, and when in doubt, refrigerate or freeze it. Warm jerky sealed in a bag sweats and can grow mold.
If you plan to make jerky in bulk, a vacuum-sealed freezer stash is the most reliable approach, and it helps to portion it by serving before sealing. Beef jerky is a concentrated protein source because the water is gone, though the exact protein per ounce depends on your recipe and cut.
How much jerky does 1 lb of beef make?
One pound of raw trimmed beef makes well under half a pound of finished jerky. Meat loses most of its weight as water, which is why jerky is expensive to buy by the pound and why a full dehydrator load of several pounds of beef produces a good stash of snacks.
What are common jerky mistakes to avoid?
- Leaving fat on the meat. It turns rancid and shortens storage life.
- Uneven slices. Thin pieces over-dry while thick ones stay soft.
- Overloading the trays. Strips that touch trap moisture and dry unevenly.
- Skipping the 160°F step. This is the safety step, not an optional one.
- Not checking early. Over-dried jerky is dry and brittle, and it cannot be fixed.

Temperature guidance here follows USDA Food Safety and Inspection Service recommendations for making jerky at home. Always confirm doneness with a food thermometer rather than by color or time.

Frequently asked questions
How long does it take to make beef jerky in a dehydrator?
Plan on 4-8 hours at 145-165°F, or 6-12 hours at lower settings around 135°F. Time depends on slice thickness, marinade moisture, tray load and humidity. Start checking at 4 hours: finished jerky bends and cracks without snapping in half.
Do you have to cook beef before dehydrating for jerky?
Not as a separate step if your dehydrator can hold 160°F, but USDA guidance says the meat should reach 160°F for safety. If your unit runs cooler, heat the marinated strips in the oven or a pan until they hit 160°F, then move them to the dehydrator at 130-140°F to dry.
How much jerky will 1 lb of beef make?
Expect well under half the raw weight: beef is mostly water, and most of it leaves during drying. Exact yield varies with the cut, how closely you trim and how dry you take it, so plan on a pound of raw beef filling a small bag and buy more beef than you think you need.
What are common jerky mistakes to avoid?
Leaving fat on the meat, slicing unevenly, overloading trays so air cannot move, skipping the 160°F safety step, and pulling jerky before it is dry. Over-drying is the other mistake: jerky that snaps and crumbles has gone too far.
