One large egg white has about 3.6 grams of protein and 17 calories, based on USDA data.
You came here for a straight answer on the protein in egg whites. Here it is, plus clear charts and tips so you can plan meals without extra tabs. All figures below use standard “large” eggs unless noted.
Protein In One Egg White, By Size And Measure
The numbers below come from nutrient data for raw egg whites. The first row is the figure most people need for a single large white. The others help when you’re working with cups or grams.
| Serving | Protein (g) | Calories |
|---|---|---|
| 1 large egg white (33 g) | 3.6 | 17 |
| 100 g egg whites | 10.9 | 52 |
| 1 cup liquid whites (≈243 g) | ≈26–27 | 126 |
| 1 oz liquid whites (28 g) | ≈3.0 | ≈15 |
Why the range in a cup? A cup is heavier than three large whites, so it carries more protein. It’s a simple scale-up from the 100 g line.
Where These Values Come From
The per-serving figures match the “egg, white, raw, fresh” entry used by dietitians and food labels. One large white shows 3.6 g protein and 17 kcal; 100 g shows 10.9 g protein and 52 kcal. You can view the full panel on Raw Egg Whites nutrition facts. For context on the whole egg, see the Egg Nutrition page from the American Egg Board.
What Counts As A “Large” White?
In the U.S. retail pack, a “large” egg averages about 50 g in shell. The white portion weighs close to 33 g. That’s the size behind the 3.6 g number. If you crack a dozen and the whites look smaller or bigger, the protein will slide a bit with weight, but not by much per egg.
Is Egg White Protein “Complete”?
Yes. Egg proteins deliver all nine required amino acids in good balance. That’s why eggs are used as a quality benchmark in textbooks and sports nutrition guides. The yolk carries a chunk of the total, but the white still gives you a lean source that mixes easily into breakfasts, shakes, and bakes.
Raw Vs Cooked Whites
Heat doesn’t remove protein; it changes structure (the clear liquid turns opaque). When you cook, some water steams off, so the same white can feel firmer and a touch denser by weight, but the grams of protein per egg stay about the same.
Foams, Omelets, And Bakes
Whipping traps air, not extra protein. A fluffy meringue still carries the same grams you started with. In omelets and bakes, oil and fillings add calories, not protein in the egg itself.
How Many Egg Whites Do You Need?
Use this quick math. One large white gives about 3.6 g protein. Want roughly 15 g? Use four. A 25 g target? Seven works. For bigger batches, a cup of liquid whites lands around 26–27 g.
Simple Targets For Meal Planning
- Light snack protein (≈10–12 g): 3 whites.
- Breakfast protein (≈15–18 g): 4–5 whites.
- Post-workout bump (≈20–25 g): 6–7 whites, or 1 cup liquid whites.
Egg Whites Vs Whole Eggs
Whole eggs bring more than protein. A large whole egg averages about 6 g protein in total, with roughly 3.6 g from the white and about 2.4–2.7 g from the yolk. The yolk also delivers choline, fat-soluble vitamins, and carotenoids. If you’re trimming calories or managing fat, whites are handy. If you want nutrients beyond protein, add some yolks to the mix.
Portion And Sodium Notes
A single large white carries about 55 mg sodium. That’s small on its own, but it adds up when you’re using many whites plus salty seasonings. Taste first, then salt. For sauces and foams, use acid (lemon or vinegar) for structure instead of heavy salt.
What About Liquid Cartons?
Cartoned whites are usually pasteurized and filtered. The label often reads “5 g protein per 3 tbsp” or similar. Check the panel; brands differ slightly. For baking and scrambles, they behave like fresh whites and make measuring by cup simple.
Amino Acids In Egg White Protein
Egg whites are rich in leucine, lysine, and valine—amino acids that support muscle repair. They’re also a handy way to add protein without extra fat. Here’s a quick view of the balance per large white, rounded for clarity.
| Amino Acid (per large white) | Amount (mg) | Notes |
|---|---|---|
| Leucine | ≈305 | Branched-chain |
| Lysine | ≈242 | Common shortfall in grains |
| Valine | ≈267 | Branched-chain |
| Isoleucine | ≈218 | Branched-chain |
| Methionine | ≈132 | Pairs with cystine |
| Histidine | ≈96 | Higher needs in growth |
| Phenylalanine | ≈226 | Aromatic amino acid |
| Threonine | ≈148 | Common in dairy and eggs |
| Tryptophan | ≈41 | Small dose, still present |
Totals vary a bit by hen diet and egg size, but the pattern holds: egg whites bring a well-rounded amino acid spread.
Simple Ways To Hit Your Number
Breakfast Ideas
- Scramble 4–5 whites with spinach and tomatoes. Add one whole egg for color and flavor.
- Microwave mug scramble: 3 whites, a pinch of cheese, and leftover veggies. Stir once mid-cook.
- Overnight oats plus 1 cup cooked whites folded in while warm. The heat sets the mix and bumps protein without heavy texture.
Lunch And Dinner Swaps
- Sauté 6–7 whites with peppers, onions, and taco spice for a quick protein filling.
- Stir 1 cup liquid whites into soup near the end and swirl to form soft ribbons.
- Build a rice bowl with 4–6 whites, steamed greens, and a sesame splash.
Baking And Smoothies
- Whites add structure to muffins and pancakes. Start by swapping in 2–3 whites for part of the liquid.
- Blend pasteurized liquid whites into a fruit smoothie for a clean protein boost.
Allergies, Safety, And Storage
Egg allergy is real. If that’s part of your history, skip this ingredient and work with a clinician. For everyone else, use fresh, clean eggs. Keep shells cold, separate raw whites from ready-to-eat foods, and cook to a safe set when serving kids, older adults, or anyone with a fragile immune system.
Fridge Time
Fresh shell eggs keep for weeks when chilled. Once separated, store whites in a clean, sealed container and use within a couple of days. For cartons, follow the printed date and keep them cold after opening.
Freezing Tips
Yes, you can freeze raw whites. Portion them in an ice cube tray, then bag the cubes. Thaw in the fridge and use in cooked dishes. Avoid whipping previously frozen whites for glossy meringue; the foam isn’t as stable.
Buying Tips And Label Clues
- Grade and size: Grade AA or A gives tighter whites; “large” keeps recipes predictable.
- Cartoned whites: Look for “100% egg whites” on the ingredient line. Flavored or seasoned versions can add sodium.
- Dates: “Sell by” differs from “use by.” When in doubt, crack into a cup first; a clean smell and firm white are good signs.
Handy Conversions For The Kitchen
When a recipe calls for eggs by count but you’d rather pour from a carton, these quick swaps keep protein close to target.
- 1 large whole egg ≈ 3 tbsp liquid egg (white + yolk).
- 1 large white ≈ 2 tbsp liquid whites.
- 8 large whites ≈ 1 cup liquid whites.
How This Article Was Compiled
Figures are drawn from nutrient databases used by dietitians and labeled products. You can verify the core numbers on the Raw Egg Whites nutrition facts page (which sources USDA records), and compare whole-egg context on the American Egg Board nutrition page. Minor calculations, like the cup and ounce rows, were scaled from the 100 g line on that same dataset.
