The highest-protein beef cuts are eye of round, top round, and tri-tip, delivering roughly 30–31 g protein per 100 g cooked, trimmed lean.
You’re here to pin down a clear answer, not sift through vague charts. In cooked beef, protein density varies by cut and by how much surface fat gets trimmed. When you compare equal cooked weights, very lean “round” and some sirloin cuts rise to the top. Below, you’ll see exactly which cuts pack the most protein per 100 g, plus what matters in the fine print—grade, trimming, and cooking method.
Quick Ranking: Highest Protein Per 100 G (Cooked)
This snapshot lists common steak and roast cuts prepared with visible fat trimmed and cooked with dry heat. Values are per 100 g cooked (not raw).
| Cut (Cooked, Trimmed) | Typical Prep | Protein (g/100 g) |
|---|---|---|
| Top Round Steak | Grilled, 0″ fat trim | ≈30.2 |
| Eye Of Round Roast | Roasted, 0″ fat trim | ≈29.9 |
| Tri-Tip Steak (Bottom Sirloin) | Broiled | ≈31.3 |
| Top Sirloin Steak | Broiled, 0″ fat trim | ≈29.2 |
| Tenderloin/Filet | Broiled | ≈26–27 |
| Ribeye Steak | Broiled | ≈23–24 |
| Brisket (Flat) | Braised | ≈24–25 |
These figures come from USDA-linked datasets compiled by MyFoodData and represent cooked weights with explicit trim levels. You can verify each number on the specific pages for top round and eye of round.
What “Most Protein” Really Means
Two ideas matter: protein per 100 g (protein density) and protein per serving. Per-100-g numbers show which cut is densest. Per-serving numbers depend on the size you eat. If your portion is larger, total protein rises even if the cut is slightly less dense. Here we stick to per-100-g cooked values so you can compare apples to apples.
Why Leaner Cuts Score Higher
Protein content is diluted by fat. Round and sirloin muscles are naturally lean and stay dense after fat trimming. Marbled steaks like ribeye carry more fat, so protein per 100 g drops even though they’re still rich in protein by absolute grams per steak.
Cooked Weight Versus Raw Weight
Cooking drives off water and renders fat. That concentrates protein per gram of cooked meat. Databases usually list separate entries for raw and cooked. The numbers in this guide use cooked weights so they reflect what lands on the plate.
Which Cut Of Beef Has The Most Protein? (Tied At The Top)
Among widely sold cuts prepared lean with dry heat, three stand out for protein density per cooked 100 g: top round steak, eye of round roast, and tri-tip steak. Depending on grade and exact trim, they cluster at roughly 30–31 g protein per 100 g cooked—making them reliable winners when someone asks which cut of beef has the most protein?
Top Round: Consistently Dense
Top round is a workhorse cut from the rear leg. It’s very lean and holds ~30 g protein per 100 g cooked when grilled and trimmed. Sliced thin against the grain, it stays reasonably tender for the macros you get.
Eye Of Round: Lean Roast Champion
Eye of round is even leaner. Roasted and trimmed to 0″ fat, it lands near 30 g protein per 100 g cooked. It’s best carved thin after a rest to keep chew in check.
Tri-Tip: Big Flavor With Strong Macros
Tri-tip sits under the sirloin and delivers ~31 g protein per 100 g when broiled. It has more beefy flavor than round, and it slices beautifully. Trim off surface fat after cooking if you want to stick close to the database values.
Beef Cuts With The Highest Protein Per 100 G (Cooked)
This section answers the close variant search while keeping real-world context. Here’s how to confirm the leaders using authoritative data and labels.
Confirm With USDA-Linked Tables
The public USDA FoodData Central database and its partner views at MyFoodData list cut-by-cut entries with “separable lean,” trim level, grade, and cooking method. Use the exact match and cooking style (like “grilled” or “broiled”) to pull the number you need.
Grades, Trimming, And Cooking Style Change The Math
Prime carries more marbling than Choice or Select. More marbling means more fat and a small drop in protein per 100 g cooked. Likewise, leaving edge fat on lowers protein density. Dry-heat methods that don’t add fat (broil, grill, roast) keep the numbers consistent; wet braises can vary a bit with moisture pickup and rendered fat.
Serving Planning Tips
- For muscle gain on a calorie budget, pick round or sirloin cuts and weigh cooked portions.
- For maximum tenderness with decent protein density, tri-tip and top sirloin hit a nice middle.
- When slicing for meal prep, rest roasts, then slice thin across the grain to keep chew down.
Practical Picks At The Butcher
Labels can be confusing. Use this plain-English map to spot high-protein options fast.
Round Primes For Protein
Look for “top round,” “eye round,” and “sirloin tip.” These are the leanest choices on most cases. Ask for 0″ trim, or trim edge fat at home after cooking.
Sirloin Standbys
“Top sirloin” and “tri-tip” bring big protein per 100 g with a little more marbling than round. They grill well, slice clean, and fit a weekly prep routine.
Cuts To Treat As Occasional
Ribeye, short ribs, and brisket are delicious, but they carry more fat. You’ll still get a large protein dose per steak; you’ll just get fewer grams per 100 g cooked compared with round and sirloin.
How To Read Labels And Entries Correctly
Database entries include tiny details that change the number on the line. Here’s a quick decoder.
| Label Detail | What It Means | Why It Matters For Protein |
|---|---|---|
| “Separable Lean Only” | Visible fat removed before analysis | Raises protein per 100 g by removing diluting fat |
| “Trimmed To 0″ Fat” | Edge fat trimmed off | Yields leaner, denser macros |
| Grade (Prime/Choice/Select) | Marbling level | More marbling lowers protein per 100 g |
| Cooked: Broiled/Grilled/Roasted | Dry-heat methods | Stable numbers; moisture loss concentrates protein |
| Cooked: Braised | Moist-heat method | May shift moisture/fat; density can differ slightly |
| Raw Vs Cooked | Weight basis for the entry | Cooked values run higher per 100 g than raw |
Sample Day: Hitting 120–160 G Protein With Beef
Here’s a simple template that favors lean cuts. Tweak portions to your calories.
Lunch
150 g top round slices, salt and pepper, with a big salad and vinaigrette (~45 g protein).
Dinner
200 g tri-tip, grilled and sliced thin, plus roasted potatoes and asparagus (~62 g protein).
Prep Box
150 g eye of round roast, chilled and sliced for sandwiches or rice bowls (~45 g protein).
Cooking Notes For Tenderness
Marinate Select Grades
Acidic marinades or a salt-only dry brine help round steaks. Give them time to rest, then slice thin across the grain.
Pull Early, Rest Well
Stop at medium-rare to medium for the best texture on sirloin and tri-tip. A 5–10 minute rest keeps juices in the meat and makes slicing cleaner.
Ground Beef And Protein Density
Ground beef varies by lean percentage. A 95% lean label beats an 80% lean label for protein per 100 g cooked. The reason is the same: less fat displaces less protein. If you want burger patties with round-like macros, aim for 93–96% lean and grill or broil them so rendered fat drips away.
That said, even 80% lean delivers a solid protein dose per patty; it’s just less dense per 100 g than round or sirloin steaks. If your goal is hitting a gram target on moderate calories, the leaner grinds win.
Mistakes That Lower Protein Per 100 G
Leaving Edge Fat On
Those white caps look small, but they tip the macros. Trim before or after cooking to keep protein density high.
Butter Bastes And Heavy Oils
Added fat coats the surface and counts toward the 100 g you weigh. Use a light spray, then finish with compound butter on the plate if you want flavor without diluting protein density.
Overcooking Lean Cuts
Well-done round turns dry and chewy. Pull at medium-rare to medium and slice thin. Texture matters if you plan to eat it often.
Protein Per Calorie: Who Wins?
On a calorie budget, top round and eye of round shine because they pair ~30 g protein per 100 g with relatively low calories. Tri-tip runs close. Once you shift to ribeye or short ribs, calories climb faster than protein.
Shopping Checklist For High-Protein Beef
- Look for cut names: top round, eye of round, sirloin tip, top sirloin, tri-tip.
- Prefer “trimmed” or ask the butcher for 0″ trim when possible.
- If choosing ground, pick 93–96% lean for protein density.
- Plan dry-heat cooking (grill, broil, roast) for clean numbers.
- Buy by weight with cooking in mind; cooked yields are smaller than raw.
Why Amino Acids Aren’t A Worry Here
Beef protein includes all essential amino acids in good balance. You don’t need to combine complementary foods to “complete” it. If you’re mixing meals, target produce and fiber for fullness and micronutrients; the meat handles the protein job on its own.
How I’d Decide For Different Goals
Lean Bulk Or Cut
Pick top round or eye of round for repetitive meals. Season assertively, rest, and slice thin for sandwiches, rice bowls, or salads. The macros are easy to budget, and you can add carbs or fats as needed.
Flavor With Strong Macros
Go tri-tip or top sirloin. They’re still dense, with a little more intramuscular fat for tenderness. Grill over high heat and rest well.
Special Dinner
Tenderloin is soft and mild, but it’s not the densest. If that’s the mood, enjoy it—just know a 200 g serving brings less total protein than the same weight of round.
Answer Recap: which cut of beef has the most protein?
For protein density per cooked 100 g, your best bets are top round, eye of round, and tri-tip. Top sirloin runs close. Choose dry-heat cooking, trim visible fat, and slice across the grain. That’s how you get the most protein bite for bite.
