How Much Protein in Beef Jerky? | Per-Ounce Numbers

A 1-ounce serving of beef jerky contains roughly 9.4 grams of protein, with most brands landing between 9 and 12 grams.

Beef jerky earns its reputation as a protein-heavy snack because dehydration strips out water and concentrates the meat’s nutrients. The exact protein in beef jerky varies by brand, cut, and processing, but the typical range stays consistent enough to plan around. For a 1-ounce (28 g) serving, most commercial options deliver between 9 and 12 grams of protein — a solid return for a portable snack.

That protein density is the whole reason jerky beats fresh cooked beef ounce-for-ounce. Cooked steak contains roughly 7 grams of protein per ounce, while jerky’s dried state pushes that number higher. But protein isn’t the only number worth checking, because sodium and serving sizes complicate the label.

Protein Per Ounce By Brand

The most reliable way to judge any jerky is the nutrition label, since “per bag” and “per serving” often differ. Here’s how common brands stack up per 1-ounce serving:

If you’re shopping specifically for the highest protein-to-calorie ratio, the leaner brands win. House of Jerky packs 12 g of protein into just 73 calories, which beats most competitors on density. Jack Link’s lands near the middle of the pack, with about 10 g per ounce and 80 calories in its single-piece example serving.

Why Do Protein Numbers Vary So Widely?

Several factors shift the protein count between one jerky and the next. The cut of beef matters first — a lean eye of round dries differently than a fattier chuck. Marination adds sugar and sodium that dilute protein percentage, while drying time removes more or less water. The result is a range from roughly 7 g per ounce on the low end to 14–15 g for homemade or very lean recipes.

Processing also plays a role. Chopped-and-formed jerky and beef sticks often contain binders or added moisture that lower protein density compared to solid-muscle strips. Check the ingredient list: if you see sugar, honey, or modified food starch early, expect protein per ounce to drift lower.

One more label trap: “per bag” vs. “per serving.” Always compare products on equal footing using the 1-ounce serving size.

What About Sodium And Other Nutrition?

Jerky’s protein strength comes with a sodium catch. USDA-derived data shows 627 mg of sodium in a single ounce, and brand examples range from roughly 410–580 mg. That’s 18–27% of the daily recommended 2,300 mg limit in one small serving. For anyone watching blood pressure, portion control matters more than the protein math.

The full USDA picture for 1 oz of beef jerky: about 116 calories, 7.26 g fat, 3.12 g carbohydrates, and 9.41 g protein. The calorie count stays modest because the serving size is small, but the nutrient density is what makes jerky a reasonable high-protein snack — as long as you’re not eating the whole bag.

Jerky is protein-dense because dehydration removes water, concentrating nutrients; this is why protein per ounce is much higher than cooked fresh beef. When you want a portable protein source that survives a backpack or desk drawer, jerky delivers — just read the serving size first.

Homemade vs. Store-Bought Protein

Making jerky at home changes the numbers substantially. Homemade recipes let you control the cut, trim visible fat, and skip added sugar, which can push protein toward 14–15 g per ounce. The trade-off is moisture: home dehydrators often leave more water in the final product, so the per-ounce protein lands wherever your drying time and meat choice take it.

Store-bought jerky wins on consistency. Commercial manufacturers standardize their recipes, so the label protein reflects what you actually get. The range stays tight at 9–12 g per ounce for most mainstream options, with leaner premium brands hitting 12 g or slightly above.
