The Average Protein Content in Cooked Steak
When calculating the protein in your steak, it is important to remember that cooking concentrates the nutrients, including protein, as the meat loses water. While a general rule of thumb suggests approximately 7 grams of protein per ounce for many cuts of cooked beef, more precise figures are available depending on the specific steak. For example, a 1-ounce serving of cooked, lean top sirloin contains around 8.32 grams of protein, while a very lean tenderloin may provide around 9 grams per ounce. These figures demonstrate that leaner cuts typically have a higher protein concentration per ounce after cooking.
Factors That Influence Protein Content
The amount of protein in your cooked steak isn't a fixed number. Several variables can cause the protein count to fluctuate slightly:
- Cut of Meat: The lean-to-fat ratio is the most significant factor. Leaner cuts, such as top round or sirloin, will have a higher protein content per ounce because fat is a non-protein component. Cuts with more marbling, like a ribeye, will have a higher fat and lower protein concentration per ounce.
- Cooking Method: The cooking method impacts how much moisture the meat loses, which in turn affects the density of the remaining protein. Gentle, moist-heat methods might retain more weight (water), resulting in a lower protein concentration per cooked ounce than high-heat, dry-cooking methods like grilling or broiling, which cause more water evaporation.
- Degree of Doneness: A steak cooked to well-done will have lost more moisture and will therefore have a higher protein concentration per ounce than one cooked rare. The total amount of protein remains the same, but it's distributed over a smaller mass. For consistent tracking, it's often recommended to calculate macros based on the raw weight.
- Trim: The amount of external fat trimmed before cooking can alter the final lean weight, which directly impacts the per-ounce protein calculation.
Comparison of Protein in Cooked Steak Cuts
To better illustrate the differences, here is a comparison table of the approximate protein, fat, and calorie content per 100 grams (about 3.5 ounces) of several popular cooked steak cuts. Note that the figures below are averages and can vary based on specific preparations and fat trimming.
| Steak Cut | Protein (g) per 100g | Fat (g) per 100g | Calories per 100g | Protein per Oz (approximate) |
|---|---|---|---|---|
| Top Round | ~29g | ~4g | ~160 | ~8.3g |
| Sirloin | ~27g | ~9g | ~200 | ~7.7g |
| Flank Steak | ~28g | ~7g | ~190 | ~8.0g |
| Tenderloin (Filet Mignon) | ~26g | ~7g | ~185 | ~7.4g |
| Ribeye | ~24g | ~20g | ~290 | ~6.9g |
| T-Bone | ~25g | ~18g | ~275 | ~7.1g |
From the table, it's clear that leaner cuts like Top Round and Sirloin are a more protein-dense choice on a per-ounce basis compared to fattier cuts like Ribeye. For those tracking macros closely, opting for leaner cuts can help meet protein goals with a lower fat intake.
The Importance of High-Quality Protein
Steak is not just a source of protein; it's a source of complete protein. This means it contains all nine essential amino acids that the human body cannot produce on its own. This makes beef an excellent choice for supporting muscle repair and growth, which is crucial for athletes and individuals on a strength training regimen. Beyond protein, steak also provides vital micronutrients like iron, zinc, and vitamin B12.
When considering steak's place in a healthy diet, the focus should be on balance and cut selection. Leaner cuts provide a significant protein boost without the high levels of saturated fat found in heavily marbled versions.

Conclusion
To conclude, the amount of protein per ounce of cooked steak can range, but for a typical cut, you can expect between 7 and 9 grams. The key takeaway is that cooking removes water, which concentrates the protein in the remaining mass, and leaner cuts will provide more protein per ounce than fattier cuts. By selecting leaner cuts and monitoring your portions, you can easily use steak as a cornerstone of a high-protein, nutritious diet. This knowledge empowers you to make informed decisions for your dietary goals, whether you are building muscle, managing weight, or simply eating healthier.
