Ground beef provides about 7 grams of protein per ounce, making a standard quarter-pound patty worth roughly 28 grams of protein when cooked. The exact amount shifts depending on the fat content and whether you’re measuring raw or cooked, but ground beef is one of the most protein-dense everyday foods available.
Protein by Serving Size
The simplest rule of thumb, based on Johns Hopkins Medicine data: one ounce of cooked beef contains about 7 grams of protein. From there, the math is straightforward for common portions.
- 3-ounce cooked serving (roughly the size of a deck of cards): ~21 grams of protein
- Quarter-pound patty (4 oz raw): ~22–28 grams of protein after cooking
- Third-pound patty (5.3 oz raw): ~28–33 grams of protein after cooking
- Half-pound patty (8 oz raw): ~40–44 grams of protein after cooking
That range exists because ground beef loses moisture and fat during cooking. A raw quarter-pound patty shrinks to roughly 3 ounces once it’s done, concentrating the protein per ounce in the finished product. When tracking protein intake, always weigh or measure after cooking for the most accurate count.
How Fat Content Changes the Numbers
Leaner ground beef contains more protein per serving because protein replaces some of the fat. A 4-ounce raw portion of 93/7 ground beef (93% lean, 7% fat) has noticeably more protein than the same weight of 73/27 ground beef. The difference works out to a few grams per serving, which adds up across a full day of eating.
Here’s what to expect from 4 ounces of raw ground beef at common lean-to-fat ratios:
- 96/4 (extra lean): ~24–25 grams of protein
- 93/7 (lean): ~22–24 grams of protein
- 85/15 (regular): ~20–22 grams of protein
- 73/27 (higher fat): ~18–19 grams of protein
If your main goal is maximizing protein while keeping calories low, 93/7 or 96/4 gives you the best ratio. But even the fattier options still deliver a substantial amount of protein per serving.
Ground Beef vs. Other Ground Meats
Ground beef holds up well against other popular ground meats. At the same lean percentage (93/7), ground beef actually contains about 2.4 more grams of protein per 4-ounce serving than ground turkey, according to USDA data analyzed by the University of Illinois Extension. Ground beef also provides more iron and zinc than turkey at the same fat level.
Ground chicken tends to be slightly lower in protein than both beef and turkey, partly because it’s often sold at higher fat percentages. Ground bison is comparable to lean ground beef in protein content, ounce for ounce, though it typically runs leaner overall. For pure protein per dollar, ground beef is hard to beat given its wide availability and frequent sales.
Protein Quality in Ground Beef
Not all protein sources are equal in how well your body can absorb and use them. Nutritional scientists measure this with a score called DIAAS (Digestible Indispensable Amino Acid Score), which rates how completely your body can use the amino acids in a food. A score above 100 means the protein is high quality and can help compensate for lower-quality proteins eaten alongside it.
Beef scores between 99 and 130 on this scale, consistently outperforming plant protein sources like beans, rice, and wheat. Research published in the British Journal of Nutrition confirmed that meat products generally provide high-quality protein with DIAAS above 100, regardless of how they’re processed. This means the protein in your ground beef, whether it’s in a burger, taco meat, or meat sauce, is efficiently absorbed and contains the full range of amino acids your muscles need.
Getting the Most Protein From Ground Beef
Cooking method matters less than you might think. Whether you grill, pan-fry, or bake ground beef, the protein content stays roughly the same. What changes is how much fat renders out. Draining the fat after browning ground beef removes calories but doesn’t significantly reduce the protein.
If you’re portioning ground beef for meal prep, a useful shortcut: one pound of raw ground beef (16 ounces) yields about 12 ounces of cooked meat and delivers approximately 80–90 grams of total protein. Split that into four servings and you get around 20–22 grams of protein each, enough to make ground beef a strong anchor for any high-protein meal.
