A 1/4 lb hamburger patty made from 80% lean ground beef and cooked provides roughly 20 grams of protein, with a small variation of 1–2 grams depending on the specific cut and cooking method.
You grab a burger after a workout, or you’re tracking macros and wondering if that quarter-pounder fits your daily numbers. The protein count seems like it should be simple — meat equals protein — but the answer changes depending on the fat ratio, whether the patty is raw or cooked, and even which brand you buy.
Here’s the straightforward version: a standard quarter-pound patty (80% lean, 20% fat) delivers about 19 to 20 grams of protein once it’s cooked. The rest of this article breaks down where that number comes from, how it shifts with different beef blends, and what fast-food burgers add to the equation.
The Baseline Protein Number
The most reliable starting point comes from the University of Rochester Medical Center’s nutrition database. It lists a 1/4 lb patty made from 80% lean ground beef and cooked pan-broiled at 19.95 Grams of Protein. That’s essentially 20 grams — a clean number to remember.
The same database shows that patty also contains 13.23 grams of total fat and 288 calories. Those numbers shift when you change the lean-to-fat ratio. An 85% lean patty, for instance, pushes protein up closer to 22 grams while dropping the fat content noticeably.
The Cooking Factor
Raw ground beef and cooked ground beef don’t weigh the same amount. Moisture evaporates during cooking, so the protein concentration per ounce goes up. A raw quarter-pound patty (4 ounces raw) will shrink to roughly 3 ounces cooked, which is why some sources report 19 grams of protein for the raw weight and 21 grams for the cooked version of the same beef.
The URMC figure uses the cooked weight, which is the more practical number for anyone logging food after the burger is on the plate.
Why The Fat Ratio Matters More Than You Think
Ground beef labeling tells you the lean-to-fat split. 80/20 means 80% lean meat and 20% fat by weight. That fat content affects both the calorie count and, indirectly, the protein density.
Here’s how different ratios change the protein picture for a quarter-pound patty:
- 80/20 (80% lean / 20% fat): The standard burger blend. Approximately 19–20 grams of protein and around 288 calories. Most common in grocery stores and casual burger joints.
- 85/15 (85% lean / 15% fat): Often labeled as ground chuck. Provides roughly 22 grams of protein with less fat — a good middle ground for flavor and macros.
- 93/7 (93% lean / 7% fat): Leaner and drier. Protein content can reach about 24 grams per quarter-pound patty, though the texture is less juicy for traditional burgers.
- Grass-fed 80/20: Some brands, like Strauss Brands, report 19 grams of protein per quarter-pound grass-fed patty — essentially the same as conventional 80/20 beef.
The takeaway: unless you’re using a very lean or very fatty blend, the protein number hovers around 20 grams. The fat content is the bigger variable for calories and mouthfeel.
Fast Food Quarter Pounders Add More Protein
Ordering a Quarter Pounder from McDonald’s adds cheese, a bun, and sometimes extra patties, which push the protein count notably higher. A standard McDonald’s Quarter Pounder contains around 28 grams of protein, according to some nutrition databases.
That extra 8 grams over a plain patty comes from the bun (which contributes a small amount of protein), the cheese (another 4–5 grams), and possibly a slightly larger or differently formulated patty. McDonald’s uses 100% fresh beef for its Quarter Pounders and cooks to order.
Comparatively, a Five Guys Cheeseburger can land closer to 40 grams of protein, largely because of the double-patty build. A frozen beef burger like a Bubba Burger 1/3 lb patty provides about 27 grams.
| Burger Type | Approx. Protein | Notes |
|---|---|---|
| Plain 1/4 lb patty (80/20, cooked) | 19–20 g | Baseline, no bun or cheese |
| McDonald’s Quarter Pounder | ~28 g | Includes bun and cheese |
| Five Guys Cheeseburger | ~40 g | Double patty with bun and cheese |
| Frozen 1/3 lb burger (e.g., Bubba) | ~27 g | Larger patty, often 85/15 blend |
| 85/15 homemade patty | ~22 g | Leaner blend, still quarter-pound |
The table helps you compare across categories, but the real variable is whether you count the bun, cheese, and extra patties as part of your meal. A plain patty gives you the straight protein number; a fully dressed burger adds 30–50% more.
How To Fit A Burger Into Your Daily Protein Target
Daily protein recommendations vary, but a common guideline is 0.36 grams per pound of body weight for a sedentary adult and 0.6 to 0.8 grams per pound for someone who exercises regularly or wants to build muscle. That means a 180-pound active person might target 108 to 144 grams of protein per day.
A quarter-pound patty at 20 grams would cover about 14–18% of that daily goal. Here’s how to think about it:
- Check the blend: An 80/20 patty gives you 20 grams; a 93/7 patty can push closer to 24. The difference matters if you eat multiple burgers per week.
- Account for toppings: A slice of American cheese adds about 5 grams of protein. A standard white bun adds 4–5 grams. That can boost a plain 20-gram patty to nearly 30 grams in a full burger.
- Consider the serving size: Some restaurants serve 1/3 lb or 1/2 lb patties. A 1/3 lb patty at 80/20 would deliver roughly 26–27 grams of protein, and a 1/2 lb patty would be around 40 grams. Adjust your tracking accordingly.
For most people, a single quarter-pound burger fits comfortably into a standard meal’s protein allocation, especially when paired with a side of vegetables or a salad rather than fries.
What The Numbers Mean For Your Meal Planning
The consistency across sources is reassuring. Whether you’re looking at the URMC academic database or the USDA-backed numbers from FatSecret, the protein figure for a cooked 80/20 quarter-pound patty consistently lands between 19 and 20 grams. The McDonald’s Quarter Pounder protein total climbs to 28 grams when you include the full sandwich, a figure from a consumer health site that aligns with broader fast-food nutrition expectations.
One nuance worth noting: raw-to-cooked weight loss means a quarter-pound of raw beef produces less than a quarter-pound of cooked meat. If you’re weighing raw ingredients before cooking, expect the final patty to be about 3 ounces and the protein to concentrate slightly.
| Beef Type | Cooked Protein (per 1/4 lb raw) |
|---|---|
| 80/20 ground beef | ~19–20 g |
| 85/15 ground beef | ~22 g |
| 93/7 ground beef | ~24 g |
| Grass-fed 80/20 | ~19 g (brand-dependent) |
The table confirms that even across different blends, the protein range is narrow — roughly 19 to 24 grams for a quarter-pound patty. The bigger choice is fat content, not protein yield.
The Bottom Line
A 1/4 lb hamburger patty made from standard 80/20 ground beef delivers about 20 grams of protein once cooked. That number moves up to 22 grams with a leaner 85/15 blend and can hit 28 grams or more when you add a bun and cheese in a fast-food sandwich. For macro tracking, the plain patty is the cleanest reference point.
If you’re balancing protein targets against other nutritional needs — like saturated fat or calorie limits — your registered dietitian can help fit that quarter-pound patty into your specific daily numbers without guesswork.
