Protein in Cottage Cheese per Cup, ½ Cup and 100 g

The protein in cottage cheese is the main reason it's back in fashion. A cup of regular 2% cottage cheese has about 23.5 g of protein for around 183 calories, and low-fat 1% has about 28 g. That puts it alongside Greek yogurt and egg whites as one of the easiest high-protein foods you can eat straight from the tub. This guide breaks down the numbers by serving size and fat level, compares it with other proteins, and covers the one real drawback: salt.

Nutrition values below come from USDA FoodData Central (SR Legacy entries for 1%, 2% and creamed 4% cottage cheese). Brands vary, so check your label.

Cottage cheese protein by serving

Per-serving figures are scaled from the per-100 g values and rounded.

1% vs 2% vs 4% cottage cheese

Per cup, that's about 28 g of protein for 1% (226 g), 23.5 g for 2% (226 g) and 23 g for full-fat 4% (210 g, since a cup of large curd weighs less).

The differences are small. Full-fat versions are creamier and a little more filling for some people, and they cost only about 20 to 25 extra calories per 100 g. Pick the one you'll actually eat. Large curd and small curd have the same nutrition; the difference is texture, and whipped versions are simply blended smooth.

Protein per calorie

Cottage cheese stands out when you compare protein to calories:

Low-fat cottage cheese gets close to chicken breast for protein per calorie, which is why it shows up on so many cutting diets. Compare other foods with the protein density calculator.

What kind of protein is in cottage cheese?

Cottage cheese is made by curdling milk and draining off the whey, so most of what's left is casein, the slower-digesting milk protein. That's one reason it's popular as an evening snack: the protein is released gradually. It's still a complete protein with all nine essential amino acids, and it's rich in leucine, the amino acid most associated with muscle protein synthesis.

The International Society of Sports Nutrition position stand on protein notes that casein before sleep can support overnight muscle protein synthesis. You don't need to time it, though; total daily protein matters most.

Sodium: the catch

Cottage cheese is salty compared with most dairy. USDA lists about 308 mg of sodium per 100 g for 2% and 406 mg for 1%, so a cup can provide 700 to 900 mg. For context, the Dietary Guidelines for Americans recommend limiting sodium to under 2,300 mg a day for adults.

Ways to manage it:

• Look for no-salt-added or reduced-sodium versions.
• Rinse it briefly in a sieve (this removes some sodium and a little of the creamy dressing).
• Pair it with low-sodium foods like fresh fruit, vegetables or oats instead of crackers and cured meats.
• Use a ½ cup serving rather than a full cup.

Other nutrients

Cottage cheese has less calcium than milk or yogurt because much of the calcium leaves with the whey during cheesemaking. If calcium matters to you, pair it with leafy greens or fortified foods. It's still a useful source of B12 and phosphorus.

Cottage cheese vs Greek yogurt

They're very close on protein. Greek yogurt is far lower in sodium; cottage cheese is often cheaper and a little more filling. The full comparison is in Greek yogurt vs cottage cheese, and Greek yogurt numbers are in protein in Greek yogurt.

How much cottage cheese to hit your protein target

Most adults who train do well with about 20 to 40 g of protein per meal. Work out your daily total with the protein intake calculator.

Easy ways to eat more cottage cheese

1. Sweet bowl: ¾ cup cottage cheese, berries, a spoon of honey and a sprinkle of oats. About 20 g protein.
2. Savoury bowl: cottage cheese with cucumber, cherry tomatoes, olive oil and black pepper.
3. Blended: blitz it smooth and use it like ricotta in pasta, or like a thick dip.
4. Eggs: stir 2 to 3 tablespoons into scrambled eggs for creamier, higher-protein eggs.
5. Pancakes: add it to the batter of protein pancakes.
6. Toast: spread on sourdough with sliced tomato or peach.
7. Dessert: blend with cocoa and a little maple syrup for a quick mousse; see high-protein desserts.

Cottage cheese for hikers and campers

Cottage cheese doesn't travel well: it's perishable and needs to stay cold. It's fine for a day hike in a cooler bag eaten within a few hours, but for anything longer use shelf-stable options. The cold food storage chart from FoodSafety.gov covers how long dairy keeps in the fridge. For trail protein, see high-protein hiking snacks.

Is it worth the cost?

Cottage cheese is often one of the cheaper protein sources in the dairy aisle. Compare it with eggs, chicken, tofu and protein powder in your local prices using the protein cost calculator, and see cheap high-protein foods.

Lactose

Cottage cheese contains some lactose, roughly 3 to 5 g per 100 g, more than hard cheese but less than milk. Many people with lactose intolerance tolerate a small serving. Lactose-free cottage cheese is available in some shops.

Bottom line

Cottage cheese gives you about 10 to 12 g of protein per 100 g and 23 to 28 g per cup, with low-fat versions offering some of the best protein per calorie of any food. Watch the sodium, choose the fat level you enjoy, and use it sweet or savoury to add an easy 15 to 25 g of protein to a meal.
