High-protein snacks, ranked by grams per serving

Biltong, Greek yogurt, cottage cheese, and tuna pouches deliver 15-25 g of protein per serving, far more than a protein bar for the money. The grams-per-serving ranking, the leucine threshold that makes a snack count, and why whole foods beat the packaged aisle.

1. 01

   Greek yogurt: ~17-20 g per single tub

   A single 170 g tub of plain nonfat Greek yogurt delivers ~17-20 g of complete, high-leucine protein, more than double regular yogurt because the straining that removes whey concentrates the casein (USDA FoodData Central). It is the highest-protein snack most people already keep in the fridge, and the casein digests slowly, which is part of why it holds off hunger well. Plain is the better buy: the protein is identical to flavored versions while the added sugar is not, and folding in frozen berries or a scoop of whey is a faster way to sweeten it without the sugar load.

2. 02

   Tuna and salmon pouches: ~17-20 g per pouch

   A standard 2.6 oz foil pouch of tuna or salmon carries ~17-20 g of complete protein and needs no draining or refrigeration, which makes it the most portable serious protein on this list (USDA). Salmon pouches add the omega-3s EPA and DHA on top. Chunk light tuna is the lower-mercury choice over albacore per EPA guidance, a distinction our guide to mercury in fish spells out, so pouches are a snack you can repeat several times a week without the mercury math becoming a concern.

3. 03

   Biltong and beef jerky: ~9-16 g per ounce

   Air-dried biltong leads at ~16 g of protein per ounce and beef jerky follows at ~9-11 g, because drying removes water and concentrates the protein into a dense, shelf-stable bite (USDA). Both are complete, high-leucine animal protein and need no refrigeration, which is their real advantage as a travel or desk snack. The one number to watch is sodium: a single ounce can carry several hundred milligrams, so a serving is a genuine protein hit but not something to graze on all afternoon.

4. 04

   Cottage cheese: ~12-14 g per half cup

   A half-cup of low-fat cottage cheese supplies ~12-14 g of protein and a full cup ~24-28 g, most of it slow-digesting casein (USDA). That slow release is why cottage cheese is a common pre-sleep protein, since it drip-feeds amino acids for hours (Res et al. 2012). It pairs well with fruit for a sweet snack or tomatoes and pepper for a savory one, and the protein density per calorie is among the best on this list, which makes it a strong choice when the goal is protein without many extra calories.

5. 05

   Roasted edamame and soy snacks: ~11-13 g per ounce

   Dry-roasted edamame delivers ~11-13 g of protein per ounce, the strongest plant-based option here because soy is one of the few plant proteins that is complete, carrying all essential amino acids in useful amounts (USDA). Roasted chickpeas and other roasted legumes trail at ~6 g per ounce. Edamame stacks fiber alongside the protein, so it does more per serving than a comparable nut, and it is the snack that lets a plant-based eater reach a real protein dose without an animal source.

6. 06

   Hard-boiled eggs and cheese: ~6-12 g per serving

   Two hard-boiled eggs supply ~12 g of complete protein and a single string-cheese stick ~6-7 g, both cheap, portable, and needing no preparation once cooked (USDA). Eggs are the reference protein for amino-acid quality, and a batch boiled at the start of the week is a grab-and-go primitive. Cheese adds calcium along with the protein but also saturated fat and sodium, so a stick or two is a sensible top-up rather than a base. Neither is the densest option alone, but paired they build a quick ~18 g snack.

7. 07

   Nuts, seeds, and nut butter: ~6-9 g per serving

   An ounce of pumpkin seeds carries ~9 g of protein, an ounce of almonds or two tablespoons of nut butter ~6-7 g (USDA). These are the lightest protein sources here and the most calorie-dense, since most of their energy is fat, so they read as protein snacks but are really fat-and-fiber snacks with protein attached. Their value is as an accompaniment, a spoon of nut butter on Greek yogurt or a scatter of pumpkin seeds over cottage cheese, rather than as the protein anchor of a snack on their own.
