A 100 g serving of cooked beef delivers about 26 g of protein; cut and cooking method shift the number.
Looking for straight answers on cooked beef protein? This guide sticks to cooked weights, gives table-ready numbers, and explains why the grams move after heat. You’ll see how cuts, fat levels, and kitchen choices change the final protein on your plate—so you can pick a steak, roast, or burger with confidence and plan meals that actually hit your target.
Beef Cooked Protein Per 100 Grams: Benchmarks
The figures below draw from USDA-linked datasets and reflect the food you eat after cooking. Treat them as anchor points; then scale up or down for your portion size.
| Cooked Beef Item (per 100 g) | Protein (g) | Notes |
|---|---|---|
| Ground beef 85% lean, patty, cooked, broiled | 25.93 | 3 oz cooked patty ≈ 22 g |
| Top sirloin steak, cooked, broiled | 27.12 | Separable lean + fat |
| Ribeye steak, cooked, broiled | 23.69 | More marbling lowers grams per 100 g |
| Top round (trimmed), cooked | 22.06 | Lean, firm bite |
| Top sirloin cap, lean only, cooked, grilled | 28.00 | Lean-only basis |
| Chuck, arm pot roast, cooked, braised | 30.00 | Trim level changes result |
| Chuck, blade roast, cooked | 16.82 | Fattier roast depresses protein per 100 g |
| Ground beef 90% lean, patty, cooked | 26.00 | Leaner grinds concentrate protein |
Across common cooked cuts and grinds, lean beef sits near 26–28 g protein per 100 g, while fattier choices read lower. The swing comes down to fat content and water loss. Heat drives off moisture; fat may render or remain. That reshapes the weight on your plate and the grams per 100 g, even when total protein in a full portion stays strong.
Why Cooking Changes The Protein Number
Two forces move the needle: moisture loss and fat change. Lean cuts like top sirloin shed water but still show a dense protein figure per 100 g. Marbled cuts keep more fat in the edible portion, so protein per 100 g looks smaller even if your 6–8 oz steak still delivers plenty of protein overall.
Food databases handle this with cooking yields and retention factors that convert raw values to cooked equivalents. In short, plan with cooked data when you care about accurate grams.
Quick Math For Real Plates
Want a fast rule you can use at the table? Keep “about 7 g per ounce” in mind for lean cooked beef. That gets you close without a calculator. A 3 oz cooked patty lands near 22 g; a 6 oz steak lands near 42 g. If your cut is fattier, shave a few grams from the per-ounce estimate.
| Cooked Portion | Protein (g) | Use Case |
|---|---|---|
| 2 oz (56 g) | ~14 | Small slider or taco filling |
| 3 oz (85 g) | ~22 | “Deck of cards” patty or steak piece |
| 4 oz (113 g) | ~28 | Single patty or compact steak |
| 5 oz (142 g) | ~35 | Hearty salad or bowl topping |
| 6 oz (170 g) | ~42 | Restaurant steak entree |
| 8 oz (227 g) | ~56 | Large steak or double patty |
| 12 oz (340 g) | ~84 | Shareable or bulk prep |
Beef Cooked Protein By Cut And Fat Level
Cut and trim decide how concentrated your grams look per 100 g. Lean roasts and sirloin steaks pack more protein into each bite. Ribeye and some chuck cuts trade gram-for-gram density for tenderness and flavor from marbling. Ground beef lets you steer the ratio with the lean percent on the label.
Ground Beef: Reading The Lean Number
Labels like 90/10 or 85/15 describe lean-to-fat. After cooking, 90/10 patties sit near 26 g per 100 g. An 85/15 patty lands in the same neighborhood, while fattier grinds drift down. Total protein per patty still tracks with cooked weight: a 3 oz cooked patty averages around 22 g.
Steaks And Roasts: Lean Versus Marbled
Top sirloin and top round skew lean and protein dense. Ribeye and blade roasts carry more fat; your per-100 g reading drops, but a normal steak portion still contributes a strong chunk of daily protein. Trimming visible fat before cooking pushes the gram density up in what you actually eat.
Protein Quality: Complete Amino Acids
Beef supplies all nine essential amino acids in amounts that qualify as complete protein. In meals that mix sides, sauces, and buns, beef still anchors the plate with full-spectrum amino acids and strong bioavailability.
Daily Needs And Where Beef Fits
Food labels use a Daily Value of 50 g protein. Many adults set targets by body weight using 0.8 g per kg as a baseline. Active lifters and older adults often pick higher personal targets. Plug cooked numbers from the tables into your plan so every steak, roast, or patty helps you land the total you want without guesswork.
Doneness, Method, And What Changes On The Plate
Grilling And Broiling
High heat drives moisture out fast, shrinks the piece, and concentrates protein per 100 g. Expect more cook loss by weight, which can make your portion look smaller even when the grams per bite rise.
Pan Searing
A hot pan behaves like grilling, though you can control fat by draining or basting. Sear, then finish to your preferred doneness; the final per-100 g figure mirrors the cut’s fat level and the moisture you lose in the pan.
Braising And Stewing
Moist heat keeps more water in the dish. The per-100 g reading of the meat itself may look lower unless you skim fat from the liquid. As a whole meal with broth and meat together, total protein still adds up well.
Portion Planning That Keeps Grams Honest
Cook With The End Weight In Mind
Raw weight overshoots protein because beef sheds water and fat. If you portion raw patties, plan for notable shrink on the grill or in a pan. Weigh a cooked piece once and note how it looks; your eye will learn that size for quick repeats.
Trim And Drain When It Helps
For ground beef, browning and draining trims fat in the finished meat. That nudges the protein percentage up in what you serve, even if the cooked weight looks similar. With roasts, chilling and lifting the fat cap from the juices gives a cleaner macros picture for leftovers.
Practical Examples You Can Copy
Simple 100 g Protein Day Built Around Beef
Lunch—4 oz cooked sirloin (≈28 g). Snack—2 oz leftover roast (≈14 g). Dinner—6 oz burger patty (≈42 g). Total ≈84 g. Add a protein-rich breakfast like strained yogurt or eggs and you’ll clear 100 g with room to spare.
Macro Tracking Without A Scale
Use visual cues: a palm-size steak near 4 oz cooked lands around 28 g; a deck-of-cards patty near 3 oz cooked lands around 22 g. Cross-check once in a while with a scale, then return to visuals for daily cooking.
Food Safety And Smart Prep
Buy fresh beef with good color and clean aroma. Keep cold, avoid cross-contamination, and cook ground beef to a safe internal temperature. Rest steaks before slicing to hold juices. Cut across the grain for tender bites, which makes protein-dense lean cuts easier to enjoy.
Key Takeaways For Tonight’s Meal
- Plan with cooked numbers. That’s what you eat.
- Lean cuts cluster near 26–28 g protein per 100 g; fattier cuts read lower per 100 g.
- Handy rule: 1 oz cooked beef ≈ 7 g protein.
- Pick flavor and budget first, then dial portion size to hit your target.
Use the phrase beef cooked protein in your meal notes if you track by theme; writing beef cooked protein reminds you to log cooked weights, not raw.
Label math uses the FDA’s protein Daily Value figure; see the Daily Value reference.
