Mozzarella is one of the most popular cheeses for high-protein meals, but the protein content in your portion depends on the type of mozzarella and how you measure it. Fresh mozzarella contains more water than low-moisture varieties, so 100 g of fresh bocconcini supplies notably less protein than 100 g of part-skim shredded mozzarella. This calculator lets you enter the amount you actually eat in grams, ounces, cups of shreds, or slices, then picks the right protein value for the type you have.
Simply choose your mozzarella type, enter a portion size, and press Calculate Protein. You'll get total protein in grams, the calories that come from that protein, and the percentage of the reference daily value (50 g) covered by one serving. The tool also includes a quick breakdown so you can see exactly how portion size and moisture affect your macronutrient totals.
Whether you're counting macros, planning meals around muscle recovery, or just trying to hit a protein target for the day, this calculator gives you a fast, reliable estimate for mozzarella.

How to Use This Calculator
Start by selecting the mozzarella type that matches what you have in the fridge. If you're using pre-shredded low-moisture mozzarella, choose the part-skim shreds option; if you're using fresh mozzarella balls, choose the fresh/bocconcini option. Then enter the amount you plan to eat and select the matching unit.
- Choose the mozzarella type from the dropdown.
- Enter the amount in the number box.
- Pick the unit that matches your measurement: grams, ounces, cups of shredded cheese, or slices.
- Press Calculate Protein to see total protein, protein calories, and percent of the reference daily value.
Protein Content by Mozzarella Type
The table below shows approximate values based on USDA FoodData Central and common product labels. Different brands may differ, so check the nutrition panel when you need precision.
| Mozzarella Type | Protein per 100 g | Protein per 1 oz (28 g) | Protein per 1 cup shredded (112 g) |
|---|---|---|---|
| Whole milk mozzarella | 22.2 g | 6.3 g | 24.9 g |
| Low-moisture part-skim shreds | 28.0 g | 7.9 g | 31.4 g |
| Low-moisture whole milk | 27.5 g | 7.8 g | 30.8 g |
| Fresh mozzarella / bocconcini | 18.1 g | 5.1 g | 20.3 g |

How the Protein Calculation Works
Mozzarella's protein content is usually listed per 100 grams. The calculator first converts your portion into grams using these factors:
- 1 ounce = 28.3495 grams
- 1 cup shredded mozzarella = 112 grams
- 1 typical slice = 28 grams
Once your portion is in grams, the protein is calculated with this formula:
Because protein provides 4 kcal per gram, the calculator also estimates the calories coming from protein. The daily value percentage is based on the FDA reference of 50 g protein per day, which is a common target used on Nutrition Facts labels.
Mozzarella in a High-Protein Diet
Mozzarella is a convenient source of complete dairy protein. It contains all nine essential amino acids and is especially high in casein, a slow-digesting protein that helps with satiety and muscle maintenance. If you're aiming to increase protein without excess fat, low-moisture part-skim mozzarella is a strong choice because it offers roughly 28 g protein per 100 g with fewer calories than many aged cheeses.
Try these practical ways to include it:
- Fold shredded part-skim mozzarella into eggs, omelets, or breakfast burritos.
- Pair fresh mozzarella with tomatoes, basil, and olive oil for a caprese salad.
- Sprinkle low-moisture shreds over soups, roasted vegetables, or whole-grain pasta.
- Roll slices around turkey, ham, or roasted red peppers for a quick snack.
- Keep mozzarella string cheese on hand for a portable 6–8 g protein snack.
If you're comparing cheese with plant-based sources, the black bean protein calculator is a useful reference for a widely eaten vegetarian protein.
Common Questions
How much protein is in one slice of mozzarella?
A typical deli slice weighs about 28 g, so a whole milk mozzarella slice provides roughly 6 g of protein. Part-skim or low-moisture slices can provide around 7–8 g per slice.
Does fresh mozzarella really have less protein than shredded?
Yes. Fresh mozzarella contains more water, so its protein density is lower by weight. Fresh mozzarella averages about 18 g protein per 100 g, whereas low-moisture shredded mozzarella can reach 28 g per 100 g. If you typically eat fresh mozzarella, you may need a larger portion to hit the same protein target.
Is the protein in mozzarella a complete protein?
Yes. Dairy proteins are complete, meaning they provide all nine essential amino acids in adequate amounts. Mozzarella is rich in casein and also contains whey proteins that support muscle protein synthesis and recovery.
What if my package label does not match the calculator's values?
Brand differences are normal. To use your exact label, convert the listed protein to per 100 g by dividing protein grams by the serving size in grams and multiplying by 100. Then compare that value to the options in the calculator or use a custom calculation manually.
Limitations and Accuracy Notes
The calculator uses representative mozzarella values, not a lab analysis. Moisture content is the biggest variable: fresh handmade mozzarella can contain even more water than the 18.1 g/100 g value used here, while some low-moisture products exceed 28 g/100 g. Shredded cheese may also contain anti-caking powders that add a small amount of weight without adding meaningful protein.
Volume-based measurements are inherently less precise than weighing. A packed cup of shredded mozzarella weighs more than a loosely filled cup, so weighing in grams is the best way to stay consistent. For a broader look at protein density across foods, see the protein per cup calculator.
