Demystifying Protein Content in Cheese
Cheese is a versatile and beloved food, but its nutritional profile, particularly its protein content, varies significantly by type. When asking, "Which cheese has the highest protein?" the answer depends on whether you're looking at protein concentration by weight or total protein per a typical serving. Hard, aged cheeses are protein powerhouses on a gram-for-gram basis, while soft, fresh cheeses like cottage cheese can provide a substantial amount of protein in a larger serving size.
The Hard Cheese Leaders: Protein by the Ounce
Hard cheeses have a low moisture content, concentrating their nutrients, including protein and fat. This is why they top the list when comparing protein per ounce.
Parmesan (Parmigiano-Reggiano)
Often considered the king of protein-rich hard cheeses, Parmesan contains around 10 to 11 grams of protein per ounce. This nutrient density is a result of its long aging process, which removes moisture and intensifies flavor. Though a serving size is typically small due to its strong, salty taste, a sprinkle over pasta, soup, or salad can significantly boost your protein intake.
Pecorino Romano
A close relative to Parmesan, Pecorino Romano is a hard Italian cheese traditionally made from sheep's milk. It offers approximately 9 grams of protein per ounce and is known for its saltier, sharper flavor. Like Parmesan, it is best used as a finishing cheese to add a potent burst of savory flavor and nutrition to dishes.
Gruyère and Swiss
These hard to semi-hard cow's milk cheeses are also excellent sources of protein. Swiss cheese, known for its mild, nutty flavor, offers around 7.7 grams of protein per ounce and is naturally lower in sodium than many other hard cheeses. Gruyère, with its rich, nutty profile, provides about 8.5 grams of protein per ounce and melts beautifully in dishes like fondue.
The Soft Cheese Contenders: Protein by Serving Size
While lower in protein per ounce than their hard counterparts, soft cheeses like cottage cheese and ricotta offer a greater amount of protein per typical serving, which is often a half-cup. This makes them ideal for building muscle or managing weight due to their high satiety factor.
Cottage Cheese
Cottage cheese is a standout for high protein and low calories. A half-cup of low-fat (1% milk fat) cottage cheese can contain around 12 to 14 grams of protein, often with less fat than a single ounce of hard cheese. It's incredibly versatile and can be enjoyed savory with vegetables or sweet with fruit and honey. For those who dislike the curds, blending it can achieve a smooth, yogurt-like consistency.
Ricotta Cheese
Made from the whey leftover from cheese-making, part-skim ricotta offers around 14 grams of protein per half-cup serving. Its mild, creamy texture makes it a great addition to both sweet and savory dishes, from lasagna and ravioli fillings to a dollop on toast with berries.
How to Choose the Right High-Protein Cheese
Your best choice depends on your specific nutritional goals and how you plan to consume the cheese. Consider the following factors:
- For maximum protein per portion: Soft cheeses like cottage cheese or ricotta are ideal because a standard serving size is much larger. This is particularly beneficial if you're looking for a satiating, protein-packed snack or meal.
- For boosting flavor with a protein kick: Hard cheeses like Parmesan and Romano are perfect as a garnish. A small amount adds significant flavor and a concentrated dose of protein, without a large volume of calories or fat.
- For lower calorie, higher protein: Low-fat or part-skim varieties of cheeses like cottage cheese and mozzarella are great choices. For instance, part-skim mozzarella has more protein than its whole-milk version because fat has been removed.
- For lower sodium options: Swiss cheese is known for its relatively low sodium content, making it a good choice for those monitoring their salt intake.
Comparison Table: High-Protein Cheeses
To provide a clear overview, here is a comparison of common high-protein cheeses based on typical serving sizes.
| Cheese Type | Serving Size | Approximate Protein | Approximate Calories | Notable Characteristics |
|---|---|---|---|---|
| Parmesan | 1 oz (28g) | ~10-11 g | ~111 | Hard, salty, concentrated protein; aged |
| Pecorino Romano | 1 oz (28g) | ~9 g | ~110 | Hard, saltier than Parmesan; made from sheep's milk |
| Swiss | 1 oz (28g) | ~8 g | ~111 | Semi-hard, nutty, lower in sodium |
| Cottage Cheese (low-fat) | 1/2 cup (~113g) | ~12-14 g | ~81 | Soft, low-calorie, high protein per serving |
| Ricotta (part-skim) | 1/2 cup (~113g) | ~14 g | ~186 | Soft, creamy, made from whey |
| Mozzarella (part-skim) | 1 oz (28g) | ~7 g | ~72 | Semi-soft, versatile, lower calorie than hard cheeses |
| Cheddar | 1 oz (28g) | ~6-7 g | ~115 | Hard to semi-hard, versatile, flavor varies by age |
The Impact of Processing and Aging
When milk is turned into cheese, the liquid whey is separated from the solid curds. For hard cheeses, more moisture is removed, and the remaining protein and fat become more concentrated. Soft cheeses like ricotta are actually made from the whey itself, while others like cottage cheese retain more moisture, which dilutes the protein concentration per ounce but allows for larger, more protein-rich serving sizes. The fermentation process in many aged cheeses also makes them lower in lactose, benefiting those with lactose intolerance.

Conclusion: Making the Right Cheese Choice
When it comes to answering "Which cheese has the highest protein?" the answer is nuanced. For raw protein density by weight, hard cheeses like Parmesan and Pecorino Romano are the winners due to their low moisture. However, for a high-protein, satiating snack or meal component, soft cheeses like low-fat cottage cheese or part-skim ricotta offer more protein per typical serving, often with fewer calories and less fat. Ultimately, the best choice depends on your specific dietary needs and how you want to use the cheese. By considering factors like fat content, serving size, and flavor profile, you can easily incorporate protein-rich cheese into a balanced nutrition plan.
