A large egg contains about 6.3 grams of protein. That number holds remarkably steady whether you boil, fry, or poach it. But the total you get depends on the size of the egg, which part you eat, and whether you cook it at all.
Protein by Egg Size
Most nutrition labels and recipes refer to a “large” egg, which weighs roughly 50 grams. According to the USDA, a large raw egg provides 6.28 grams of protein. A jumbo egg (63 grams) bumps that up to about 7.9 grams. If you’re buying medium or small eggs, expect something closer to 5 to 5.5 grams each.
Egg sizes also vary by country. A “large” egg in the UK weighs about 68 grams, noticeably heavier than its US counterpart, and delivers around 7.5 grams of protein. If you’re following a recipe or nutrition plan from another country, the size label alone can throw your count off by a gram or more per egg.
Egg White vs. Yolk
A common assumption is that all the protein lives in the white. The white does carry the majority, roughly 60 to 65 percent of the total, but the yolk contributes a meaningful 35 to 40 percent. For a large egg, that works out to about 3.6 grams in the white and 2.7 grams in the yolk.
Gram for gram, the yolk is actually more protein-dense. Egg yolk contains 15.6 grams of protein per 100 grams, compared to 10.2 grams per 100 grams for egg white. The white just happens to make up a larger portion of the egg’s total weight. If you’re tossing yolks to “save protein,” you’re doing the opposite. People skip yolks to cut calories and fat, not because the white is nutritionally superior for protein.
Cooking Barely Changes the Number
Cooking method has almost no effect on how much protein ends up on your plate. A large fried egg contains 6.26 grams. A poached egg has 6.25 grams. A hard-boiled egg comes in at 6.3 grams. The differences are negligible and mostly reflect small variations in water loss during cooking rather than any breakdown of the protein itself.
What cooking does change, dramatically, is how much of that protein your body can actually use. Protein digestion from raw eggs is around 40 percent lower than from cooked eggs. Heat unfolds the tightly wound protein structures, making them far easier for your digestive enzymes to break apart. So while a raw egg and a cooked egg contain the same protein on paper, your body absorbs significantly more from the cooked version. If you’re blending raw eggs into smoothies for the protein, you’re leaving nearly half of it on the table.
How Egg Protein Compares to Other Foods
Eggs are one of the highest-quality protein sources available. They contain all nine essential amino acids in proportions that closely match what the human body needs. This is why eggs have long served as a reference standard in protein quality research.
In practical terms, two large eggs give you about 12.5 grams of protein for around 140 calories. That’s comparable to roughly 2 ounces of chicken breast, a cup of milk, or half a cup of cooked lentils. Eggs won’t single-handedly meet your daily protein needs (most adults need 50 to 70 grams per day), but they’re a convenient, inexpensive building block. A three-egg omelet gets you close to 19 grams before you add any cheese or meat.
Quick Reference by Count
- 1 large egg: 6.3 g protein
- 2 large eggs: 12.6 g protein
- 3 large eggs: 18.8 g protein
- 4 egg whites only: ~14.4 g protein
- 1 jumbo egg: 7.9 g protein
If you’re tracking protein intake for fitness or weight management, eggs are one of the easiest foods to count. The protein content barely shifts across cooking methods, the per-egg number is consistent, and they pair well with other high-protein foods at any meal.
