Among common cuts, beef shank and top round deliver the highest protein per 100 grams when cooked, with very lean round cuts close behind.
Shopping for steak or roast and want the best protein bang per bite? The answer lives in lean, hard-working muscles. On a cooked-weight basis, shank crosscuts and top round usually sit at the top, with eye of round, sirloin tip, and flank right behind. Ribeye and brisket taste rich, but their extra fat lowers protein density gram for gram. When people ask about the beef part with most protein, they usually mean a cooked-weight comparison across common retail cuts. Below, you’ll see clear rankings, the reasons they win, and simple ways to hit the numbers in your kitchen.
Beef Part With Most Protein By 100 Grams
Protein varies with trim and cooking loss, so the fairest way to rank is per 100 grams of cooked meat. Using reference values compiled from nutrient databases, these cuts lead on protein density. Links in the table go to detailed nutrient pages where available.
| Cut (Cooked) | Protein/100 g | Notes |
|---|---|---|
| Shank Crosscuts, Simmered | 34 g | Very lean working muscle; top protein density.MyFoodData |
| Top Round Steak, Grilled | ~30 g | Lean round subprimal; strong per-gram protein.MyFoodData |
| Eye Of Round Roast, Roasted | ~28 g | Lean roast that stays high in protein per 100 g.Data summary |
| Flank Steak, Broiled | ~28 g | Thin, lean cut; quick to cook, easy to slice.MyFoodData |
| Sirloin Tip (Side) Steak | ~27–28 g | Very lean sirloin region option.Cut info |
| Ribeye (Trimmed Filet), Grilled | ~29 g | Trimmed lean center can test near 29 g/100 g.MyFoodData |
| Tenderloin, Broiled | ~26–27 g | Very tender; moderate fat; strong amino profile. |
| Brisket, Cooked | ~27 g | Rich collagen and fat reduce protein density.MyFoodData |
Why Lean Working Muscles Top The List
Protein density rises when a cut carries little intramuscular fat and little external fat. Muscles that do steady work—like the shank and round—fit that profile. When water evaporates during cooking and fat renders, the remaining portion holds a higher share of protein by weight. That’s why a lean roast from the round often outruns a buttery ribeye on a per-gram basis.
Trim And Cooking Loss Change The Math
Protein per 100 grams is a cooked-weight metric. Two things shift it: how much fat you trim and how much moisture cooks off. A fully trimmed steak broiled to medium-rare keeps more water and stays heavier, which slightly lowers protein per 100 grams even if the total protein per steak is the same. A well-done slice sheds more water, so the same absolute protein is packed into fewer grams of meat, nudging the figure upward.
Why “Per 100 Grams” Beats “Per Serving” For Ranking
Serving sizes hide differences. A 3-ounce portion from a fatty cut can show a similar protein number as the same portion from a lean cut. Per-100-gram values level the field so you can compare cuts without portion games. For definitive nutrient references, the USDA’s database and derivative tools present values you can sort and compare by cut and cook method.USDA FoodData Central
How To Pick The Right Cut For Your Goal
Choose based on where you want the protein to come from in your day. For the beef part with most protein in a calorie-aware plan, lean round cuts fit best. If your calories are tight, the round family shines. If you prefer a little more marbling, sirloin or a trimmed ribeye filet delivers strong protein with more fat. If you slow-cook, shank gives standout protein density and deep beef flavor for soups and braises.
Leanest High-Protein Picks For Meal Prep
Top round, eye of round, and sirloin tip slice well when chilled. Roast or grill, rest fully, then carve thin across the grain. Pack portions by weight so your macro math stays consistent across lunches. Keep slices thin, pack with greens or grains you like, and stash a jar of pan juices for moist reheats. Label sauces and dates too.
Cooking Moves That Protect Protein Yield
Protein does not burn off, but you can lose juices that carry dissolved proteins. Small tweaks keep more goodness on the plate.
Salt Early, Heat Smart
Dry-brine with salt at least 45 minutes ahead; it draws salt into the meat and helps retain moisture during searing. Use a thermometer to stop at your target doneness. Medium-rare to medium (130–140°F, 54–60°C) protects juiciness while keeping chew friendly for lean cuts.
Slice Against The Grain
Round and shank run with long fibers. Keep bites tender by slicing thin against the grain. That cut angle shortens the muscle fibers, so lean steaks eat better without extra fat.
Protein Per Serving Size (3 Oz / 85 g)
If you track by serving, these are typical cooked values from the same high-protein cuts. Exact numbers move with trim and doneness, but the pecking order holds.
| Cut (Cooked) | Protein/85 g | Kitchen Notes |
|---|---|---|
| Shank Crosscuts, Simmered | ~29 g | Great in soups and stews; skim fat after chilling.MyFoodData |
| Top Round Steak, Grilled | ~25–26 g | Marinate briefly; thin slices boost tenderness.MyFoodData |
| Eye Of Round Roast, Roasted | ~24 g | Roast low and slice thin for sandwiches. |
| Flank Steak, Broiled | ~24 g | Quick cook; rest 5 minutes; carve across the grain.MyFoodData |
| Sirloin Tip (Side) Steak | ~23–24 g | Lean stir-fry or fajitas after a short marinade.Cut info |
| Ribeye (Trimmed Filet), Grilled | ~24–26 g | Ask for a tight trim; sear hot, finish gentle. |
| Brisket, Cooked | ~23 g | Chill and slice; reheat gently to keep slices intact. |
Shopping Tips That Keep The Numbers On Your Side
Read The Cut Name Carefully
Words like “eye,” “top,” and “tip” in the round family point to leaner pieces. “Cap,” “deckle,” and heavy external fat signal lower protein density per 100 grams. If a package lists trim level, “0-inch fat” or “well trimmed” improves protein per gram.
Choose Cooking Method To Match The Cut
Lean steaks like top round and flank need fast heat and a short rest. Tougher lean cuts like shank reward time and moisture. Low-and-slow breaks collagen into gelatin, which coats fibers and helps lean meat feel juicier without adding fat.
Batch Cook, Then Portion By Weight
Roast a whole eye of round or top round, chill, then portion into weighed packs. Label the weight on each bag. When you log meals, you’ll know exactly how many grams of cooked meat—and protein—you’re getting.
Weigh cooked portions after resting to capture true yield accurately. Keep a scale on the counter to make this step painless.
Quick Takeaways
- Shank crosscuts and top round lead for protein per 100 grams cooked.
- Eye of round, sirloin tip, and flank are close and easy to portion.
- Trim level and doneness shift per-gram protein but not the pecking order.
- Use per-100-gram numbers for clean comparisons, then pick a cut that matches your cooking style.
