Cooked beef provides about 21–31 g of protein per 3 oz serving, depending on cut and fat level.
Beef is one of the most reliable protein foods on the table. Still, the numbers swing with cut, fat %, and cooking method. This guide breaks it down with clear tables, real-world portions, and simple rules you can use at the store or in your kitchen.
Protein In Beef At A Glance
Most lean steaks sit near the top of the range. Fattier cuts edge lower because fat displaces lean tissue. Ground beef varies the most because fat % varies. Use the table below as your quick map.
Protein By Beef Cut (Cooked)
| Beef Cut (Cooked, Lean Where Shown) | Protein / 100 g | Protein / 3 oz (85 g) |
|---|---|---|
| Top Sirloin Steak, lean | ~31 g | ~26 g |
| Top Round (London Broil), lean | ~29 g | ~24 g |
| Flank Steak, lean | ~27–28 g | ~23–24 g |
| Tenderloin/Filet, lean | ~26–27 g | ~22–23 g |
| Ribeye, trimmed | ~24–26 g | ~20–22 g |
| Brisket (flat), trimmed | ~26–27 g | ~22–23 g |
| Ground Beef 90% Lean, pan-browned | ~26–27 g | ~22–23 g |
| Ground Beef 85% Lean, pan-broiled patty | ~24–25 g | ~20–21 g |
| Ground Beef 80% Lean, pan-broiled patty | ~23–24 g | ~19–20 g |
These figures reflect common cooked values drawn from standard nutrient datasets used by dietitians and labels. Steaks trimmed to less visible fat trend higher. Ground beef shifts with fat %, drain-off, and how firmly patties are cooked.
Beef- How Much Protein? By Cut And Cooking
Two things set your number: the cut and what happens in the pan. Lean steaks such as top sirloin and top round pack the most protein per bite. Fattier cuts like ribeye carry more fat, so the protein per 100 g drops a bit. Ground beef follows its lean-to-fat ratio.
Raw Vs Cooked Weight
Cooked meat loses water and some fat. That shrink means the same piece weighs less after cooking, so protein appears concentrated per 100 g. When you compare values, make sure you compare cooked to cooked or raw to raw. Kitchen rule: 4 oz raw steak often lands near 3 oz cooked lean. Portion planning gets much easier once you use cooked weights on your plate.
How Cooking Style Changes The Number
Grilling, broiling, air frying, and pan searing drive off moisture. Braising keeps more water in the muscle fibers. Sear-and-rest methods can keep yields high without drying out the lean tissue. The protein itself stays; the water around it shifts. That’s why a drier steak can show a higher protein number per 100 g than the same steak cooked gently.
Ground Beef Protein: Read The Label Like A Pro
Ground beef wears its truth on the label: 80/20, 85/15, 90/10. Those pairs tell you lean % and fat %. The higher the lean number, the higher the protein per bite. A 3 oz cooked patty from 85% lean ground beef lands near 21 g of protein; 90% lean lands closer to 22–23 g. Pan-broiling and draining remove some fat, which nudges the per-serving protein a touch higher compared with a patty cooked in its own drippings.
Quick Picks For Common Goals
- High protein, lower fat: top sirloin, top round, eye of round, 90–93% lean ground beef.
- Balanced flavor and protein: strip steak, tenderloin, flank steak, 85% lean ground beef.
- Richer cut, moderate protein per gram: ribeye, short ribs, brisket point.
How Much Protein Does Beef Add To Your Day?
Most labels and diet tools use a reference value of 50 g protein per day for adults. That comes from U.S. label law and helps you judge % Daily Value. You can read the FDA’s plain guide to DVs on its site, including the 50 g value and how %DV works on packages. Linking it here helps you match the math you see on labels in stores.
Check: Daily Values for Nutrients (FDA).
Simple Serving Math
A 3 oz cooked portion of lean steak gives about 24–26 g of protein, close to half of that 50 g reference. Two such servings across the day push you near the full Daily Value before you add eggs, yogurt, beans, or grains. That’s why a modest steak can anchor a full plate without overshooting your total.
Choosing Cuts: Taste, Budget, And Protein
Protein is only part of the story. Cost, flavor, and tenderness matter too. Top sirloin and top round win on price per gram of protein. Tenderloin brings a luxury texture with slightly lower protein per 100 g than top sirloin, but it still sits high. Ribeye brings marbling and a buttery bite; protein per bite is a bit lower due to fat.
Shopping Pointers That Keep Protein High
- Pick cuts labeled “lean” or trimmed to 1/8" fat when protein density matters.
- For ground beef, choose 90% lean or higher when you want more protein per calorie.
- Plan portions by cooked weight. A kitchen scale once or twice pays off fast.
- Save money: buy a larger roast (top round or sirloin tip), roast once, slice for several meals.
Beef Protein Quality
Beef protein contains all essential amino acids in a pattern the body can use easily. That’s why labels often show a strong %DV for protein on modest portions. Research on retail cuts shows the lean portions of common steaks qualify as a good or excellent source of protein under U.S. labeling rules, and also bring B12, zinc, selenium, and niacin in helpful amounts.

Portion Guide You Can Use Tonight
Here’s a plain view of common servings. Use these as rough kitchen targets when you plan a plate or track macros.
Protein By Serving Size
| Serving | Typical Choice | Protein |
|---|---|---|
| 3 oz cooked steak | Top sirloin, lean | ~26 g |
| 3 oz cooked steak | Top round, lean | ~24 g |
| 3 oz cooked patty | Ground beef 90% lean | ~22–23 g |
| 3 oz cooked patty | Ground beef 85% lean | ~20–21 g |
| 4 oz cooked steak | Flank, lean | ~31–33 g |
| 6 oz cooked steak | Strip or tenderloin | ~44–48 g |
| 8 oz cooked steak | Top sirloin, lean | ~69–70 g |
Label Law Notes That Help You Read Packages
U.S. labels use a 50 g Daily Value for protein on the Nutrition Facts panel. That figure appears in FDA rules that govern how %DV is shown. If a package makes a protein claim, the %DV can reflect protein quality tests used for labeling. This is background info for packagers, yet it helps explain why %DV sometimes shows up on meat labels and sometimes does not.

Beef Protein Vs Other Proteins (Quick Context)
Per cooked ounce, lean beef sits near the same band as pork loin and a touch below skinless chicken breast. Beans and tofu can match a steak across a full plate by weight, though the portion sizes look different. Mixing beef with beans, grains, and vegetables rounds out a plate and stretches budget while keeping protein intake steady.
Smart Ways To Hit A Target Protein Intake
Start with your plate, not a calculator. Many adults land near 50 g protein per day using common meals: yogurt or eggs in the morning, a protein food at lunch, and a 3–6 oz cooked portion of beef, chicken, fish, or tofu at dinner. If you track macros, set beef portions based on cooked weights from the tables above. Round portions up or down to match appetite, goals, and the rest of the menu.
Seven Easy Plate Ideas
- Top sirloin strips, roasted potatoes, green beans.
- Flank steak tacos with pico and cabbage slaw.
- Lean ground beef chili with beans and peppers.
- Tenderloin medallions, garlic mushrooms, salad greens.
- Beef and broccoli stir-fry over rice.
- Stuffed peppers with 90% lean ground beef and quinoa.
- Open-face steak sandwich on whole-grain toast with arugula.
Storing And Cooking For Best Protein Yield
Keep steaks cold, cook within a safe window, and rest meat a few minutes before slicing. Slice across the grain to keep bite size friendly, which can help with portion control. Use a thermometer for doneness: 145°F for whole cuts with a short rest is a common target for tenderness and food safety best practice at home.
Final Take: Beef- How Much Protein?
Use this as your quick anchor: 3 oz cooked lean steak gives about 24–26 g of protein; 85% lean patties sit near 20–21 g; 90% lean patties land closer to 22–23 g. Choose leaner cuts when you want more protein per calorie. Choose richer cuts when flavor is the goal and balance the rest of the plate.
