Cooked beef delivers about 22–26 g of complete protein per 3-oz (85 g) serving; lean cuts reach the high end.
Beef is a dense source of high-quality protein with all nine indispensable amino acids. This guide shows how much protein you get by cut and serving, how cooking changes numbers, and how to plan portions that fit your day.
Beef Protein Nutrition Facts: Per 100 Grams And Per Serving
Protein numbers vary with cut, fat trim, and cooking method. To keep things consistent, the values below use cooked weight. Three ounces cooked equals about 85 grams. That is the portion listed on many labels and diet trackers.
| Cut (Cooked) | Protein / 100 g | Protein / 3 oz (85 g) |
|---|---|---|
| Top Sirloin (broiled) | 31 g | 26 g |
| Tenderloin / Filet (broiled) | 28 g | 24 g |
| Flank Steak (broiled) | 27 g | 23 g |
| Top Round (broiled) | 31 g | 27 g |
| Ribeye (grilled) | 23–25 g | 20–22 g |
| Brisket, Flat (roasted) | 26 g | 22 g |
| Ground Beef 85% Lean (broiled) | 26 g | 22 g |
| Ground Beef 80% Lean (broiled) | 24 g | 20 g |
These figures are drawn from U.S. reference datasets for cooked beef. The 3-oz serving lands near one deck of cards in size and often yields about 20–27 grams of protein, with leaner steaks trending higher.
What Drives The Differences By Cut
Protein concentration tracks with leanness and moisture. Trims with less marbling and lower fat retain a bigger share of protein per bite. Cooking style matters too: grilling or broiling drops water, which nudges protein per 100 grams upward.
Planning Servings For Daily Needs
Many adults target about 0.8 grams of protein per kilogram of body weight per day. That is a common baseline. Spread protein across meals so each plate carries a steady dose for muscle repair and appetite control.
Beef Protein Facts By Cut And Serving Size
For a quick plan, pair a lean cut with a portion that reaches your meal target. A 3-oz serving of top sirloin hits the mid-20s in grams. If you need a larger bump, a 4–5-oz cooked portion usually lands near 30–40 grams, depending on cut.
Ground Beef: 80%, 85%, 90% Lean
Lean-to-fat ratio shapes the numbers. At the same cooked weight, 90% lean patties carry more protein than 80% lean because less space is taken by fat. Draining rendered fat does not remove protein; the patty’s protein stays in the meat.
Cooked Weight Vs. Raw Weight
Labels and trackers sometimes list raw values. Beef loses water and fat during cooking, so 4 ounces raw may shrink to about 3 ounces cooked. That is why many reference tables report both raw and cooked weights side by side.
Beef Protein Nutrition Facts For Popular Meals
Use these meal-level estimates to plan quickly. They stack common cuts with typical cooked portions you might plate on a weeknight.
| Meal Portion | Cut | Protein (g) |
|---|---|---|
| 3 oz fajita strips | Flank steak | ~23 |
| 4 oz steak bites | Top sirloin | ~33 |
| 5 oz grilled medallions | Tenderloin | ~40 |
| 1 patty (85 g cooked) | Ground beef 85% lean | ~22 |
| 1 cup chopped roast | Top round | ~35 |
| 3 oz smoked slices | Brisket flat | ~22 |
| 4 oz steak | Strip or ribeye | ~28–30 |
What Else You Get With The Protein
Beef brings iron, zinc, and B-vitamins. Heme iron is well absorbed. Zinc supports enzymes. B12 appears only in animal foods. Trim choice shifts fat and calories, but the protein stays consistently high across lean cuts.
Simple Ways To Keep Protein High
- Pick leaner trims like top sirloin, eye of round, or top round.
- Use dry-heat methods such as broiling or grilling to keep moisture loss predictable.
- Weigh cooked portions for accurate tracking.
- Slice across the grain for pleasant texture at smaller portions.
How To Match Portions To Daily Goals
The common baseline for adults is 0.8 g/kg/day; you can find that value in the National Academies’ Dietary Reference Intakes. Many meal plans also use the MyPlate ounce-equivalent system where 1 ounce of cooked meat counts as one unit; see the USDA’s Protein Foods guidance.
Quick Math For A Day
Take your body weight in kilograms and multiply by 0.8 to get a daily gram target. Split that across three meals. If your target is 70 grams, two 3-oz servings of lean steak plus yogurt or beans at another meal can meet it.
Clarifying Common Tracking Questions
Is Beef A Complete Protein?
Yes. Beef supplies all indispensable amino acids in amounts that support muscle repair. That is why small portions still deliver a meaningful hit of protein.
Does Marbling Change Protein?
Fat displaces protein by weight. A marbled ribeye can show fewer grams per 100 grams than a lean round steak. If you match protein grams, the lean cut will usually come with fewer calories.
What About Sodium?
Fresh beef carries little sodium. Seasoning and sauces add more than the meat itself. If tracking sodium, measure the add-ons, not just the steak.
Use the tables above whenever you need a quick check on beef protein nutrition facts. The cut list lets you compare like-for-like portions at a glance.
For label work or menu planning, keep beef protein nutrition facts handy. It shortens the path from cut choice to grams on the plate.
Smart Ways To Shop And Prep
Shop Lean For Protein Density
Look for labels reading 90–95% lean on ground beef. For steaks, choose trims from round or sirloin when you want the most protein per bite.
Prep Steps That Keep Portions Honest
- Chill cooked steak before slicing to capture juices instead of losing them on the board.
- Use a kitchen scale for cooked weights; note that 85 grams cooked is 3 ounces.
- Batch-cook portions and label containers with cut, weight, and grams.
Cooking Loss Is Normal
Expect water and fat loss as heat rises. That loss concentrates protein per 100 grams, which is why cooked tables look higher than raw tables, even though total protein for the piece stays tied to its final cooked weight.
Protein Density Tiers By Cut
When you want the most grams in the fewest bites, choose cuts where lean muscle dominates. Here is a simple way to sort the case at the butcher.
Higher Protein Per 100 Grams
- Top sirloin, eye of round, top round
- Sirloin tip, tri-tip, knuckle
- Lean ground beef at 90–95% lean
Middle Of The Road
- Tenderloin medallions
- Flank and skirt for quick sauté strips
- Ground beef at 85% lean
Lower Protein Per 100 Grams
- Ribeye and strip with heavy marbling
- Short ribs and chuck short ribs
- Ground beef at 80% lean
Protein Per Calorie: Quick Ratios
Lean steaks often deliver about one gram of protein for 5–6 calories. A marbled ribeye can drift closer to one gram for 9–10 calories. If you track calories tightly, move up the leanness scale and trim exterior fat after cooking.
Cooking Choices That Keep Protein Targets On Track
Dry-Heat Methods
Broiling and grilling heat the surface hard and fast. The steak sheds some water and fat, so protein per 100 grams edges up. Pat steaks dry, salt evenly, and rest on a rack after cooking to keep juices in the meat.
Moist-Heat Methods
Braising keeps moisture around the meat. Total protein in the portion stays the same, but the cooked weight can be higher from liquid uptake. Track the meat portion itself when you log protein.
Grinding And Patties
Grinding blends lean and fat. Choose the lean level that matches your goals. Pan-broiled patties shed fat as they cook. Weigh after cooking, then read the table for the matching lean level.
Sample Day Using Beef And Other Proteins
Balanced days mix beef with dairy, eggs, and plants. Here is a simple template that spreads protein from morning to night while keeping prep easy.
- Breakfast: Greek yogurt bowl (15–20 g) with fruit and oats.
- Lunch: 3-oz top sirloin strips over salad greens (about 26 g).
- Snack: Cottage cheese cup or soy smoothie (12–20 g).
- Dinner: 4-oz tenderloin with vegetables and potatoes (about 30+ g).
This spread places 20–35 grams at each meal, a range many lifters and walkers like because it helps muscle protein turnover and satiety through the day.
Label Notes When You Buy Packaged Beef
- Check whether the panel lists raw or cooked values; match your log to that basis.
- Ground beef must display lean percentage; the higher the number, the more protein per 100 grams.
- Some labels add serving tips. Portion marks like “3 oz cooked” map cleanly to the tables above.
Storage, Reheat, And Food Safety Basics
Refrigerate cooked beef within two hours. Store in shallow containers to chill quickly. Reheat to a steaming hot center. These steps protect quality while you batch-prep portions for the week.
Do Resting And Marinades Change Protein?
Resting keeps juices inside the steak, which helps texture and yield, but the protein count per cooked weight stays the same. Marinades can add flavor and a little moisture, yet they do not raise protein unless you add a dairy base or blended legumes. Even then, the bump is tiny compared with the meat itself.
Keep a small note on your fridge with two lines: 3-oz cooked steak ≈ mid-20s grams; 4-oz cooked steak ≈ low-30s grams. With that, planning becomes quick math at the stove.
