How Much Protein Is in an Egg? Fewer Grams Than You Think

A large egg holds about 6 grams of protein — solid, complete, but smaller than most people assume. Where it sits in the egg, how cooking changes nothing, and what your omelette actually adds up to.

Eggs have a reputation as the protein food. The grams are more modest than the reputation.

Short answer: one large egg (~50 g without shell) carries about 6.3 grams of protein — roughly 3.6 g in the white and 2.7 g in the yolk, per USDA FoodData Central. One caveat for European shoppers: EU eggs are graded by in-shell weight, so a size M sits nearer 6 g and a size L nearer 7–8 g. Complete, high-quality protein, yes. A protein bomb, no: a two-egg breakfast delivers about 12.5 g, which is less than half of what most people aim for in a main meal.

Where the protein actually sits

The folk wisdom says “the white is the protein, the yolk is the fat.” Half right.

Part of a large eggProteinWhat else
White (~33 g)~3.6 galmost nothing else
Yolk (~17 g)~2.7 g~4.5 g fat, most vitamins
Whole egg (~50 g)~6.3 g~72 kcal

The yolk holds over 40% of the egg’s protein — plus nearly all of its iron, choline, B12 and vitamin D. Tossing yolks throws away protein too, not just fat.

Cooking changes the texture, not the grams

Heat denatures egg proteins — unfolds and sets them — which is why a fried white is solid and an omelette holds shape. That structural change slightly improves digestibility of the white. What it doesn’t do is remove protein. Boiled, scrambled, fried: still ~6 g per egg.

What a real egg meal adds up to

This is where “eggs = protein” quietly under-delivers, and where seeing the whole meal helps:

BreakfastProtein
2 eggs, plain~12.5 g
3-egg omelette~19 g
2 eggs + 2 slices rye bread~19 g
2 eggs + 150 g cottage cheese (serek wiejski)~29 g

The cottage-cheese row is the honest lesson: the egg is a solid contributor, but the meal only approaches 30 g because of what sits next to it.

That’s also the difference between counting protein and placing it. In 3sense Food, a logged breakfast doesn’t just say “19 g protein” — it shows 13 g came from the eggs and 6 g from the bread, so you know which part of the plate is doing the work. If you’re building meals around a daily target, start with how much protein per day actually makes sense.

Quick answers.

How much protein is in one egg?

A large egg (about 50 g without shell) holds roughly 6 grams of protein — around 3.6 g in the white and 2.7 g in the yolk, per USDA FoodData Central figures.

Is egg protein complete?

Yes. Egg protein contains all nine essential amino acids in strong proportions, which is why it has long been used as a reference protein in nutrition research.

Do you lose protein by cooking eggs?

No meaningful amount. Cooking changes the protein's structure (that's why the white turns solid) and can improve digestibility — the grams stay put.

How many eggs do I need for 30 g of protein?

About five large eggs — or two eggs plus another protein source. Most people pair eggs with dairy, bread or meat rather than eating five.
