Angus steak delivers about 24–28 grams of protein per 100 grams cooked, with the cut, trim, and doneness shaping the final count.
Shopping for beef and trying to hit a protein target? Angus beef is a breed label, not a separate food group. That means the grams you get come down to the steak cut, how much fat you trim, and how you cook it. This guide shows realistic protein ranges for popular Angus cuts, how serving size maps to grams, and simple ways to get a predictable number on your plate.
Angus Steak Protein By Cut: Quick Reference
The numbers below reflect cooked values from USDA-based datasets and industry labeling tools. They land in a tight band because muscle protein doesn’t swing wildly between cuts; fat and moisture are the big movers.
| Cut (Cooked) | Typical Prep | Protein (g/100 g) |
|---|---|---|
| Top Sirloin | Broiled or grilled, lean trim | 26–27 |
| Tenderloin/Filet | Broiled or grilled, lean trim | 25–26 |
| Strip (New York) | Grilled, lean trim | 25–27 |
| Ribeye | Grilled, trimmed to reduce surface fat | 24–26 |
| Flank | Broiled or grilled, sliced across grain | 27–28 |
| Skirt | Quick sear or grill | 26–27 |
| Chuck/Chuck Eye | Braised or grilled to medium | 25–26 |
Why a range and not a single number? Raw steaks lose water and some fat as they cook. The leaner the cut and the drier the finish, the greater the protein density by weight. You’ll see the same pattern across breeds, including Angus.
Does Angus Change The Protein?
Short answer: breed doesn’t overhaul the protein in muscle tissue. Angus is known for marbling and grading outcomes, which mainly shift fat content and juiciness. When two steaks of the same cut are cooked the same way and trimmed to the same leanness, the protein grams sit in the same neighborhood. USDA nutrient references and retail labeling tools treat beef on a cut-by-cut basis, not by breed, which is why you’ll see values listed for sirloin, strip, ribeye, and so on rather than a separate “Angus” row.
How To Predict Your Grams From A Steak On The Plate
You don’t need a lab. Pick the cut style, weigh the cooked portion, and multiply by the typical protein density for that cut. Here’s a simple way to ballpark it at home:
Step-By-Step Quick Math
- Pick your baseline from the table above. Say 26 g per 100 g for top sirloin.
- Weigh the cooked portion. A 6-ounce cooked steak weighs about 170 g.
- Multiply: 170 g × 0.26 ≈ 44 g protein.
Don’t have a scale? A deck-of-cards–size cooked piece is roughly 3 ounces (about 85 g) and lands near 22–23 g protein for lean cuts.
Serving Size Conversions You’ll Use A Lot
These cooked conversions make menu math easy when you’re tracking protein targets or planning meals for a week.
Everyday Portions And Protein
- 3 oz cooked (≈85 g): ~21–23 g protein on leaner cuts; ~20–22 g on ribeye.
- 6 oz cooked (≈170 g): ~42–46 g protein on leaner cuts; ~40–44 g on ribeye.
- 8 oz cooked (≈227 g): ~54–61 g protein on leaner cuts; ~50–57 g on ribeye.
These ranges reflect normal kitchen outcomes, not perfect lab control. A trim pass that removes edge fat won’t dent protein much but will change total calories.
What Actually Moves The Protein Number
Cut And Leanness
Round and sirloin live on the leaner side and carry slightly more protein per bite. Ribeye brings more intramuscular fat, so the protein per 100 g runs a touch lower. The muscle protein in steak is still dense, which is why all cuts land near the mid-20s per 100 g cooked.
Cook Level And Moisture Loss
Cooking to medium or beyond drives off more water, concentrating nutrients per 100 g. A steak pulled at medium-rare can show a gram or two less protein per 100 g than the same steak cooked longer, even though the total protein in that piece of meat hasn’t changed; the weight did.
Trimming And Surface Fat
Surface fat doesn’t carry protein. Trimming the cap on a ribeye lowers calories and leaves the muscle protein intact, so your grams per serving may look higher once you re-weigh the cooked portion without that fat.
How This Guide Sources Numbers
Protein values come from U.S. datasets used for retail labels and diet analysis. For cut-level nutrient data by raw/cooked state, the industry tool based on USDA SR Legacy is a handy reference; see the nutrient database for fresh meat labeling. USDA’s FoodData Central SR Legacy search lists dozens of cooked steak entries that cluster around 24–28 g protein per 100 g. If you’re building meal plans or printing labels, those are the primary places to verify a specific cut and cooking method.
Practical Targets For Training And Meal Prep
Many lifters shoot for 30–40 g of protein per meal. With Angus cuts, that’s simple:
- Lean route (sirloin/top round): Serve 5–6 oz cooked to land around 35–45 g.
- Marbled route (ribeye/strip): Serve 6–7 oz cooked to land around 40–48 g.
Pairing with eggs, Greek yogurt, cottage cheese, or a small whey shake lets you keep steak portions moderate while still hitting a daily goal.
Nutrition Beyond Protein
Steak brings iron, zinc, selenium, and vitamin B12. Those nutrients don’t vanish with breed changes. The big swing is fat and calories with fattier cuts, not protein. If you’re trimming calories, pick sirloin or round more often and save ribeye for days when you want extra flavor and don’t mind a richer plate.
Cook Smart For Consistent Results
Pick A Doneness And Stick With It
Changing doneness week to week makes the cooked weight bounce. Lock in a target—say, medium-rare—and your grams per 100 g will stay steadier.
Salt Early, Rest After
Season 30–60 minutes before cooking. Rest 5–10 minutes after the sear so juices redistribute. You’ll carve cleaner slices and waste less moisture on the board, which keeps your portion weight stable.
Trim After Cooking
Trim visible surface fat after resting. Then weigh your serving so your protein math matches what you’re actually eating.
Protein Planning: From Cuts To Plates
Use the table below to turn common cooked serving sizes into grams for two everyday profiles: a leaner steak pattern and a ribeye/strip pattern. The numbers land inside the cut-level ranges shown earlier.
| Cooked Portion | Lean Cuts (Sirloin/Round) | Marbled Cuts (Ribeye/Strip) |
|---|---|---|
| 3 oz (≈85 g) | 22–23 g protein | 20–22 g protein |
| 6 oz (≈170 g) | 44–46 g protein | 40–44 g protein |
| 8 oz (≈227 g) | 58–61 g protein | 50–57 g protein |
Raw Weight vs. Cooked Weight
Most food logs and nutrition labels reference cooked values. If you buy by the pound and portion raw, expect 25–35% weight loss by the time the steak hits your plate, depending on trim and cook level. A raw 8-ounce sirloin often lands near 5.5–6 ounces cooked. That’s one reason two people can both say “I ate an eight-ounce steak” yet record different protein numbers—their raw and cooked points differ.
Angus Choices For Different Goals
Lean Cut, High Protein
Top sirloin, eye of round, and bottom round keep protein dense with fewer calories. Great for meal prep bowls, steak salads, and sliced wraps.
Balanced Cut For Steak Night
Strip brings a friendly fat-to-protein ratio and takes well to a quick sear. Good pick when you want flavor without going all-in on richness.
Richer Cut For Flavor
Ribeye shines when you want a buttery bite. Protein stays strong, but calories run higher. Trim the outer cap after cooking if you want to tighten the macros.
Method Notes And Limits
Values here come from cooked, trimmed steak records used in labeling and dietary analysis. Different but normal kitchen choices—like a heavy marinade, generous butter basting, or leaving the fat cap on—shift calories and weight more than protein in the muscle. If you need a precise number for medical tracking or clinical research, look up the exact cut and cooking method in a primary database and weigh your cooked serving to match.
Quick Reference Tips
- Think in hundreds: most cooked steaks land near 25–27 g protein per 100 g.
- Lean cuts give slightly more protein per bite; marbled cuts give more calories per bite.
- Weigh cooked portions, not raw, for the cleanest log entries.
- Trim after resting, then slice. Your plate weight will be closer to what you eat.
Bottom Line For Meal Planning
Angus steak is a dependable protein source across cuts. Pick the style you like, measure the cooked serving, and use the cut-level band to plan the rest of the plate. With a steady cook method and a scale, your protein math stays tight week after week.
