How much protein is in cheese? A guide by type
Cheese is an easy, everyday source of protein, but the amount varies widely depending on the type. A snack-size serving of parmesan and a bowl of cottage cheese can land in a similar range even though they look nothing alike.
Here is a practical breakdown of how much protein common cheeses provide, why the numbers differ so much, and how to fit cheese into a protein tracking routine without overthinking it.
Quick answer
Most common cheeses provide somewhere between 6 and 12 grams of protein per ounce, with hard, aged cheeses like parmesan near the top of that range and soft, fresh cheeses like cream cheese near the bottom. Cottage cheese stands out as a higher-protein option relative to its calories, at roughly 12 to 14 grams per half-cup serving. Proto can log a cheese-based meal or snack from a photo, so the protein counts without any manual entry.
Protein in common cheeses
These are typical values for common serving sizes. Exact numbers vary by brand and fat content, so check the label for a specific product if you want a precise figure.
| Cheese | Typical serving | Approximate protein |
|---|---|---|
| Cottage cheese | 1/2 cup (113 g) | 12 to 14 g |
| Parmesan | 1 oz (28 g) | 10 to 11 g |
| Swiss | 1 oz (28 g) | 7 to 8 g |
| Cheddar | 1 oz (28 g) | 6 to 7 g |
| Mozzarella, part-skim | 1 oz (28 g) | 6 to 7 g |
| Feta | 1 oz (28 g) | 4 g |
| Cream cheese | 1 oz (28 g) | 1 to 2 g |
Why cheese protein numbers vary so much
The biggest factor is water content. Soft, fresh cheeses like cream cheese and brie hold onto a lot of water, which dilutes the protein per ounce. Hard, aged cheeses like parmesan and aged cheddar lose most of their moisture during aging, which concentrates the protein into a smaller, denser serving.
Fat content plays a smaller role too. Full-fat versions of the same cheese usually have slightly less protein by weight than reduced-fat versions of the same type, since fat displaces some of the protein and moisture in the mix.
Fitting cheese into a protein tracking routine
Cheese works well as a quick way to round out protein at a meal or snack, especially paired with something higher in fiber like fruit, vegetables, or whole grains. Because the protein content varies so much by type, tracking what you actually ate matters more than assuming a flat number for cheese in general.
Proto reads a photo of your plate and estimates protein automatically, so a cheese board, an omelet, or a cottage cheese bowl logs quickly without weighing anything out by hand. If you want the bigger picture on tracking protein day to day, see our roundup of the best protein tracker app.
Takeaway
Cheese can be a genuinely useful protein source, but the amount depends heavily on the type. Harder, aged cheeses like parmesan pack the most protein per ounce, cottage cheese is a standout for its calorie to protein ratio, and softer cheeses contribute less protein than their size suggests.

Frequently asked questions
Is cheese a good source of protein?
Yes. Most cheeses provide a meaningful amount of protein per serving, though the exact amount varies a lot by type. Harder, aged cheeses tend to be more protein-dense per ounce than soft, fresh cheeses.
How much protein is in cottage cheese?
A typical half-cup serving of cottage cheese provides roughly 12 to 14 grams of protein, making it one of the higher-protein options among common cheeses relative to its calorie count.
Which cheese has the most protein per serving?
Hard, aged cheeses like parmesan tend to be the most protein-dense by weight, since they contain less water than soft cheeses. A small amount goes a long way, both in protein and in flavor.
Can Proto track protein from cheese and other foods together?
Yes. Proto reads a photo of your plate and estimates protein and fiber automatically, so a cheese-based meal or snack logs alongside everything else without manual entry.
