How Much Protein is in Cooked Lean Ground Beef? An In-Depth Look at Different Ratios

January 7, 2026 •

3 min read

According to the USDA, a 3-ounce (85g) serving of cooked 90% lean ground beef contains approximately 22 grams of high-quality protein. The exact protein content can vary significantly based on the meat's initial lean-to-fat ratio and how it is prepared, as water and fat are cooked away.

Quick Summary

The protein content of cooked lean ground beef varies by its lean-to-fat ratio, with cooking concentrating the nutrients as moisture and fat are lost.

Key Points

Higher Lean-to-Fat Ratio = More Protein: Leaner ground beef options, such as 93/7, yield a higher protein content per ounce of cooked meat due to less fat and moisture.
Cooking Concentrates Nutrients: While the absolute protein mass doesn't significantly change, the removal of water and fat during cooking increases the protein concentration per gram of the final cooked product.
Standard 3oz Serving: A typical 3-ounce (85g) serving of cooked lean ground beef offers between 21 and 25 grams of protein, depending on the specific lean-to-fat ratio.
Complete Protein Source: Lean ground beef provides all nine essential amino acids necessary for muscle repair and growth, making it a valuable dietary protein.
Drain for Higher Concentration: For a more protein-dense meal with fewer calories from fat, it is recommended to drain the rendered fat after cooking.
Cooking Method Matters: Cooking methods that reduce more fat, like pan-browning, can result in a higher protein-to-fat ratio in the finished dish compared to methods that retain fat.

Understanding Ground Beef Ratios

When purchasing ground beef, you'll see a label with a numerical ratio, such as 93/7, 90/10, or 85/15. These numbers indicate the percentage of lean meat to fat by weight before cooking. For example, 93/7 ground beef is 93% lean meat and 7% fat. A higher lean percentage means less fat and water content, which affects the final protein concentration after cooking.

The Impact of Cooking on Protein Content

During the cooking process, ground beef loses water and renders fat, causing the overall weight to decrease. Because the protein itself is not lost (unless it drains with rendered fat, which is minimal), the remaining meat becomes more concentrated in protein. This is why the protein amount in a serving of cooked beef is higher per gram than in raw beef. For example, a 4-ounce serving of raw ground beef will yield roughly a 3-ounce serving once cooked.

Comparing Protein Across Different Ratios

For those tracking macronutrients, understanding the difference in protein yield from various ground beef ratios is crucial. The following table highlights the approximate protein content per 3-ounce (85g) serving of cooked, pan-browned, and drained ground beef based on USDA data.


Lean-to-Fat Ratio	Approximate Protein (per 3 oz / 85g cooked)
95/5 (Extra Lean)	~26 grams
93/7 (Lean)	~25 grams
90/10 (Lean)	~22 grams
85/15 (Lean)	~21 grams

Factors That Influence Protein Values

Several factors can influence the final nutritional profile of your cooked lean ground beef. While the lean-to-fat ratio is the most significant, consider these other variables:

Cooking Method: High-heat methods like pan-frying or broiling can render and drain more fat than slow-cooking, leading to a higher protein concentration.
Draining Practices: Thoroughly draining the rendered fat after browning can significantly increase the protein concentration and decrease the calorie count of the final product.
Meat Source and Preparation: The specific cut of beef used, the breed of cattle, and the grinding process can all lead to slight variations in nutritional content.
Added Ingredients: If you add any binders or seasonings, the overall protein and calorie count will be affected.

The Nutritional Benefits of Lean Ground Beef

Beyond its high-quality protein, lean ground beef offers a wealth of essential nutrients that support a healthy diet. It's a complete protein source, meaning it provides all nine essential amino acids that your body cannot produce on its own.

A Nutritious Powerhouse

Here's a breakdown of some of the key nutrients found in lean ground beef:

Iron: An essential mineral for oxygen transport throughout the body. A 3.5 oz serving of cooked lean beef can provide a significant portion of your daily iron needs.
Zinc: Crucial for immune function, wound healing, and cell division.
Vitamin B12: Important for nerve function and the production of DNA and red blood cells. Lean beef is an excellent natural source of this vitamin.
Niacin (B3): Plays a role in energy metabolism and cellular function.

How to Maximize Your Protein Intake

If your goal is to consume more protein with less fat, choose leaner ratios like 93/7 or 95/5. Always cook the beef to a medium or medium-well doneness and drain the rendered fat thoroughly. Pair your ground beef with nutrient-dense vegetables and whole grains to create a balanced, high-protein meal. For an easy way to estimate your protein needs, consider consulting a nutritionist or online calculators, but remember that individual needs vary based on age, weight, and activity level.

Conclusion

In summary, cooked lean ground beef is a fantastic source of high-quality protein and other essential nutrients. The final protein content per serving depends directly on the initial lean-to-fat ratio, with leaner options offering a higher concentration. By understanding the effects of cooking and choosing the right ratio for your dietary goals, you can effectively incorporate this versatile and nutritious meat into a balanced meal plan. The key is to select the leanest option available, cook it appropriately, and drain excess fat to maximize its protein density per serving.

Frequently Asked Questions

Cooked ground beef has a higher concentration of protein per ounce or gram than raw. This is because cooking removes water and renders fat, causing the meat to shrink and concentrating the protein that remains.

The lean-to-fat ratio significantly impacts the protein content. A higher lean percentage (e.g., 93/7) results in more protein per gram of cooked beef compared to a lower lean percentage (e.g., 85/15), as there is less fat to displace the protein.

For a high-protein diet aiming to minimize fat intake, 93/7 ground beef is the better choice. It is a leaner option and will provide a higher concentration of protein per gram of cooked meat.

A 100-gram (3.5 oz) serving of cooked 90/10 ground beef contains approximately 25 grams of protein, based on USDA-reported data for pan-broiled patties.

Nutrition labels can list different protein values depending on whether they are based on raw or cooked weight. This is why it's important to check if the label specifies 'raw' or 'cooked' in its calculations.

Lean ground beef is a nutrient-dense food that provides not only protein but also significant amounts of iron, zinc, and Vitamin B12, among other minerals.

Draining the rendered fat after cooking does not remove the protein. It increases the protein concentration per serving by removing excess fat, making the final product leaner and more protein-dense.
