A cooked 3-oz serving of Angus steak delivers about 22–26 g protein; the cut and fat level set the exact number.
Shopping for Angus steaks or burgers and wondering how much protein you’ll get per serving? You’ll see strong numbers across the board. Breed affects marbling and marketing more than protein grams; the real swing comes from cut, fat percentage, and cooking loss. This guide shows typical protein ranges per serving, explains why numbers vary, and helps you choose portions that match your goals.
Angus Beef Protein Per Serving: Cut And Cooking Matter
Protein density in cooked beef clusters in a tight band. Leaner, denser cuts come out near the top. Fattier, more marbled cuts slide a little lower per 100 g because fat displaces lean tissue. The table below summarizes common retail choices with cooked, edible portions.
| Cut Or Style (Cooked) | Typical Serving | Protein |
|---|---|---|
| Top sirloin, trimmed lean | 3 oz (85 g) | ~23–26 g |
| Tenderloin (filet), lean | 3 oz (85 g) | ~22–25 g |
| Ribeye, lean portion | 3 oz (85 g) | ~22–25 g |
| Chuck roast, shredded lean | 3 oz (85 g) | ~21–24 g |
| Brisket, trimmed | 3 oz (85 g) | ~20–23 g |
| Ground beef 90% lean | 3 oz (85 g) | ~22–25 g |
| Ground beef 80% lean | 3 oz (85 g) | ~20–23 g |
Why Protein Numbers Shift From Cut To Cut
Protein grams track with how much lean tissue makes it onto your plate. Fat has zero protein, so a steak with more marbling yields fewer grams per 100 g of cooked weight. Trimming external fat and choosing “lean only” portions raises protein density. Even within one cut, retail grades and trimming practices change the math a bit.
Cooked Weight Beats Raw Weight For Real-World Portions
Water and fat render during searing, grilling, and roasting. That moisture loss concentrates the protein that remains. Labels and databases often list both raw and cooked values; use the cooked values for what you actually eat. A raw 4-oz sirloin might land near 3 oz cooked, which is why many databases present results per 3 oz cooked.
Ground Beef: Fat Percent Tells The Story
Lean blends pack more protein per bite because less of the patty is fat. A cooked 100 g portion of 80% lean ground beef often shows about 24 g protein, while 90% lean sits higher. Patties still vary with press loss, griddle heat, and doneness.
How Angus Compares With “Regular” Beef
Angus is a breed label, not a separate food category in nutrient databases. When you scan official data, beef entries list cut, grade, and fat trim rather than breed. That’s a handy signal that protein grams in Angus cuts align with the same cut from other common breeds when trimmed and cooked the same way.
Serving Size Tips That Make Tracking Easy
Most folks track steak in two ways: ounces cooked or grams cooked. Three ounces cooked fits a deck-of-cards visual and lands near a quarter pound raw. If you slice steak, weigh the edible lean portion after trimming caps and big seams of fat so your protein math stays honest.
Quick Estimating Shortcuts
- Per ounce cooked steak: ~7 g protein for lean cuts, ~6 g for well-marbled cuts.
- Per 100 g cooked steak: ~24–30 g protein for lean portions; ground 80% sits near ~24 g.
- Two thin slices from a roast (about 2 oz): ~12–14 g protein.
Evidence Backing The Ranges
Lab-tested nutrient databases report tight protein ranges across popular cuts. You’ll see ribeye filet near 30% protein by weight when trimmed to lean portions, and cooked ground beef 80% lean showing just under 24 g protein per 100 g. Peer-reviewed work on retail steaks also confirms that the biggest swing between cuts is fat content, not the protein fraction of the lean. You can review the raw numbers in the USDA’s retail beef nutrient tables and the FAO’s report on protein scoring systems. These sources are detailed and transparent.

Cooking Method And Doneness Change Yield
Searing and grilling lose more moisture on the surface. Braising trades some render loss for broth-bound juices, but the lean you eat still concentrates. Higher doneness drives more water loss. That’s why a well-done burger of the same raw weight can look smaller yet show similar protein grams per cooked ounce.
Marinating And Resting
Salted marinades pull in a little water pre-cook and help retain juices. Resting after heat lets juices redistribute so less spills on the board. Neither step adds protein; they simply change how much moisture stays in the meat, which affects the final weight you place on the scale.
Practical Ways To Hit Protein Targets With Angus Cuts
Build plates around a cooked portion that suits your day. A 3-oz lean steak lands in the low-20s for grams. A hearty 6-oz portion doubles that. Burgers make tracking simple: one cooked quarter-pound patty from a 90% lean blend reaches the mid-20s in grams; a fattier blend lands a touch lower.
Smart Pairings
- Serve sliced steak over grains and vegetables to round out iron, zinc, and fiber.
- Add eggs or dairy at breakfast on lighter steak days to balance intake across meals.
- Plan a lean cut the day after a rich ribeye so your weekly totals stay steady.
Protein Quality: Beef Delivers Complete Amino Acids
Beyond grams, beef ranks high for amino acid profile and digestibility. Modern scoring systems like DIAAS place meat well above many plant sources, with scores near or above 1.00. That reflects strong levels of indispensable amino acids and high digestibility of the protein in cooked beef. Processing and added ingredients can shift scores a bit, yet plain steak and plain ground beef remain strong choices for complete protein.
How To Read Nutrition Numbers For Steak At Home
Kitchen scales, a quick glance at cut type, and a reliable database are all you need. Weigh the edible portion after cooking and trimming. Match the cut in a trusted table. Then log either per ounce or per 100 g, keeping the same method from meal to meal so your records compare cleanly.
Label Clues In The Meat Case
- Look for grade and trimming notes like “lean only” or fat thickness.
- Ground beef lists lean percentage; higher lean means more protein per bite.
- Steaks with big fat caps and seams cook down more; the lean center gives you the protein.
Portion Planning For Different Goals
Active days or heavier training can call for larger servings at one meal. Rest days might use a smaller piece paired with beans or dairy to keep daily totals steady. Since beef is rich in B-vitamins, iron, and zinc, even modest servings can pull weight in a balanced menu.
Cooked Serving Guide (Handy Reference)
Use this quick table when you’re portioning steak or burgers at the stove. The grams assume typical cooked yields from lean portions.
| Cooked Portion | Estimated Protein | Use Case |
|---|---|---|
| 2 oz (57 g) | ~12–14 g | Taco or salad topper |
| 3 oz (85 g) | ~20–26 g | Standard plate serving |
| 4 oz (113 g) | ~27–34 g | Higher-protein lunch |
| 6 oz (170 g) | ~40–50 g | Single-plate dinner |
| 8 oz (227 g) | ~54–66 g | Shareable steak |
| Quarter-pound burger (113 g cooked) | ~22–28 g | Classic burger night |
Common Portion Questions Answered Briefly
Bone-in steaks: log the edible lean after slicing. Braises and stews: weigh the meat pieces; track the broth separately. Marinades and seasonings: add taste and water, not protein. Resting drip: mostly water and fat; the protein stays in the lean.
Putting It All Together
Pick the cut you enjoy, trim to your liking, and track by cooked weight. Lean portions such as sirloin and tenderloin sit at the higher end of protein density per ounce. Richer cuts like ribeye bring great flavor with a small drop in protein per 100 g. Ground blends follow the lean percentage on the label.
Sources And Data Notes
Numbers in the tables reflect cooked, edible portions from standard nutrient databases and peer-reviewed work on retail steaks. Databases group beef by cut, fat trim, and cooking method rather than breed labels. That’s why Angus entries mirror other beef entries when the cut and trim match.
