A standard beef burger patty contains roughly 20 to 28 grams of protein, depending on the size of the patty and the leanness of the meat. A 3-ounce cooked patty made from 90/10 ground beef delivers about 22 grams, while larger quarter-pound (4-ounce) patties push closer to 28 to 30 grams. That single patty covers a significant chunk of most people’s daily protein needs.
Protein by Patty Size and Lean Ratio
Most of the protein variation in a beef burger comes down to two things: how big the patty is and how lean the meat is. Leaner beef packs more protein per ounce because there’s less fat taking up space. A 3-ounce cooked patty of 90% lean beef has about 22 grams of protein. Scale that up to a 4-ounce patty and you’re looking at roughly 29 grams. A thick half-pounder (8 ounces raw, which cooks down to around 6 ounces) can deliver 40 grams or more.
Fattier blends like 80/20 ground beef have slightly less protein per ounce because fat replaces some of the muscle tissue. The difference isn’t dramatic, typically a few grams less per patty, but it adds up if you’re tracking closely. For most people eating a single burger at dinner, either blend provides a substantial protein serving.
Raw Weight vs. Cooked Weight
One detail that trips people up is the difference between raw and cooked measurements. Cooking doesn’t destroy protein. A patty that starts at 4 ounces raw will shrink to roughly 3 ounces after cooking as moisture and some fat cook off, but the total grams of protein stay the same. The meat just becomes more protein-dense per ounce. If you’re weighing your food for tracking purposes, use the nutrition data that matches the state the meat is in when you put it on the scale: raw numbers for raw weight, cooked numbers for cooked weight.
How Other Burger Meats Compare
Beef isn’t the only option, and some alternatives actually pack more protein per serving. Based on 3.5-ounce servings of cooked meat:
- Ground turkey: 26 grams of protein
- Ground chicken: 23 grams of protein
- Ground bison: 20 grams of protein
Turkey burgers come out on top here, offering a few more grams of protein than a similarly sized beef patty while typically being leaner. Bison lands slightly lower in protein but is very lean, making it a popular choice for people watching their fat intake. Chicken burgers fall in the middle and tend to have a milder flavor that takes well to seasoning.
Plant-Based Burgers
The Impossible Burger and Beyond Burger both deliver respectable protein for plant-based options. A 4-ounce Impossible Burger patty has 19 grams, and a same-sized Beyond Burger has 20 grams. That’s a bit less than a comparable beef patty but still a meaningful serving.
There’s a quality difference worth knowing about, though. Research from the University of Illinois compared how well the body can absorb and use the protein in these burgers using a score called DIAAS, which measures how completely your body digests the protein and how well its amino acid profile matches what you need. Lean beef and pork burgers scored highest. The Impossible Burger scored close to 80% lean beef for adults and older children, meaning your body uses its protein almost as efficiently. The Beyond Burger scored notably lower than all the other burgers tested. This doesn’t mean plant-based burgers are a poor protein source, but gram-for-gram, your body may extract less usable protein from them compared to meat.
What a Burger Contributes to Your Daily Needs
The baseline recommendation for protein is 0.8 grams per kilogram of body weight, which works out to about 0.36 grams per pound. For a 140-pound person, that’s around 53 grams per day. A single quarter-pound beef burger patty covers more than half of that minimum in one sitting. For a 180-pound person, the target is closer to 65 grams, and one patty still gets you roughly 40 to 45% of the way there.
Keep in mind that this baseline is really a floor, the minimum to prevent deficiency rather than an ideal target. Active people, older adults working to maintain muscle mass, and pregnant women (who are advised to aim for 75 to 100 grams daily) all benefit from higher intakes. If you’re strength training or trying to build muscle, many nutrition experts suggest 1.2 to 1.6 grams per kilogram, which puts daily targets between 95 and 130 grams for a 180-pound person. In that context, a burger patty is a solid contribution but far from a full day’s worth.
The Full Burger, Not Just the Patty
The patty is the protein star, but the rest of the burger adds a bit too. A standard white hamburger bun contributes about 4 to 5 grams of protein. A slice of American cheese adds roughly 4 grams, while cheddar or Swiss can add 5 to 7 grams per slice. So a complete cheeseburger on a bun can easily reach 35 to 40 grams of protein total, even before adding extras like bacon (another 3 to 4 grams per slice).
A fast-food single patty burger typically lands on the lower end because chains often use smaller patties, around 2 to 3 ounces cooked. A basic McDonald’s hamburger, for example, has about 12 to 14 grams of protein. Double patties and quarter-pounders bring those numbers much closer to what you’d get from a homemade burger.
