How much protein is in cottage cheese?

A complete dairy protein — with a slow-release twist

Cottage cheese earns its reputation for one straightforward reason: it is a complete protein, supplying every essential amino acid in the proportions your body can actually use. That puts it in the same top tier as eggs, milk, and meat — no food-combining tricks required.

What makes it genuinely different from other high-protein dairy is how that protein behaves. Cottage cheese is overwhelmingly casein — the slow-digesting milk protein — rather than the fast-absorbing whey that dominates a typical protein shake. Casein curdles in the stomach and releases its amino acids in a slow drip over several hours instead of one quick burst. That single property is why cottage cheese has been the classic pre-bed protein for decades: a bowl before sleep keeps a trickle of amino acids flowing through the overnight fast, exactly when muscle repair is happening and you’d otherwise go 7–8 hours with nothing coming in. Greek yogurt is excellent too, but it skews toward whey; if you specifically want a slow, overnight protein, cottage cheese is the more deliberate pick.

Reading the number on this page (and the catch)

The figures here are the USDA reference for 1% lowfat cottage cheese — about 12.4 g of protein per 100 g, or roughly 14 g in a half cup (113 g). The first thing worth knowing is that fat percentage barely moves the protein: 2% and 4% (full-fat) cottage cheese carry very similar protein to the 1% shown here. What changes is the fat and the calorie count — the 4% style is creamier and richer, with more saturated fat, for essentially the same protein payload. So “lowfat vs. regular” is a texture-and-calorie decision, not a protein one.

The real variable to watch is sodium, and it doesn’t show up in the protein column. Salt is added during production, and brands are all over the map. This reference sits at a moderate ~406 mg per 100 g, but plenty of tubs run saltier than that, and a handful are sold no-salt-added for people managing blood pressure. The macro table above is a faithful baseline; your actual tub can swing meaningfully on salt, so the label is the final word. (One more quirk: most of the modest carbohydrate here is lactose, which matters if you’re sensitive to it.)

Hitting your protein goal with it

For planning, anchor everything to ~14 g per half cup. A full cup gets you to roughly 25 g — more than most protein bars — and a cup and a half clears 35 g, which is a serious dent in a day’s target from a single, inexpensive food. Stir in fruit or a swirl of honey for breakfast, spoon the savory version over toast or into eggs, or keep a bowl for the last thing you eat at night. To turn these per-serving numbers into a daily number that fits your body weight and training, see how much protein per day. And if you want the convenience without guessing on salt, the branded picks below are the easy route to high-protein, lower-sodium tubs — already graded so you can skip the label-reading.
