Half a cup of raw egg whites contains about 63 calories (≈122 g), based on USDA’s 52 kcal per 100 g.
Why You’re Asking
If you cook with egg whites, a quick, reliable calorie number saves time in the kitchen and on your tracker. Here’s a clear answer plus easy conversions you can use on the fly.
What Counts As 1/2 Cup Egg Whites
In home cooking, 1/2 cup equals 8 tablespoons. The American Egg Board’s guide puts 1 large egg white at 2 tablespoons, so 1/2 cup is usually 4 large whites. By weight, 1/2 cup of raw whites lands near 121–122 grams.
Half-Cup Egg White Calories: Quick Reference
Use these numbers when you need a fast estimate or when a recipe gives volume only.
| Portion | Weight (g) | Calories |
|---|---|---|
| 1 large egg white | 33 | 17 |
| 1/4 cup egg whites | 61 | 32 |
| 1/2 cup egg whites | 122 | 63 |
| 1 cup egg whites | 243 | 126 |
| 100 g egg whites | 100 | 52 |
How We Calculated The Numbers
USDA-based data lists raw egg whites at 52 calories and 10.9 g protein per 100 g. One cup of raw whites weighs about 243 g, which aligns with kitchen charts that equate 8–10 large whites per cup. Halving that cup gives roughly 121.5 g, so 121.5 g × 0.52 kcal/g ≈ 63 calories for the half-cup.
Small Swings You May See
Egg size varies. Large whites are the usual baseline, but medium or extra-large can change the count by a few grams per white. Carton egg whites are pasteurized; plain versions match raw whites closely, while flavored or seasoned versions can add sodium or tiny carb amounts. Any number on a label wins for that specific product.
Protein In 1/2 Cup Egg Whites
This is the main reason many people choose whites. Using the same USDA data, 1/2 cup (≈121.5 g) provides around 13.2 g of protein. A single large white has about 3.6 g, so four whites sit near 14–15 g in practice. Both views tell the same story: lean protein with very little fat.

Conversions You Can Trust
When a recipe lists “egg whites” by count, these swaps help you hit the same ballpark without stopping to weigh:
- 1 large egg white = 2 tablespoons
- 4 large egg whites ≈ 1/2 cup
- 8 large egg whites ≈ 1 cup
Practical Ways To Measure
- For shakes: pour 1/2 cup from a carton, then add fruit or yogurt.
- For omelets: crack 4 large eggs and keep the whites, or use 1/2 cup from a carton.
- For baking: weigh 122 g on a digital scale if precision matters.
Flavor And Texture Tips
- A pinch of salt tightens and brightens the foam for meringues.
- For scramble-style whites, start on medium heat and move the pan often; pull them when glossy, not dry.
- A teaspoon of olive oil or butter adds moisture with a small calorie bump; count it.
Sodium Heads-Up
Raw whites bring natural sodium. If you’re watching salt, season late and taste first. Carton products may carry a bit more sodium; check the label.
Half Cup Egg Whites Calories — Everyday Uses
That single 1/2-cup measure fits in loads of meals. It slides into a breakfast burrito, bulks up fried rice, or lightens pancakes. It also folds into cottage cheese or Greek yogurt for a protein lift with no yolk.
Ideas That Start With 1/2 Cup
- Veggie scramble: 1/2 cup egg whites, chopped spinach, tomato, scallion, black pepper.
- Egg-white wrap: Pour 1/2 cup into a small skillet, cook thin like a crepe, fill with hummus and cucumber.
- Quick fried rice: Fold 1/2 cup whipped whites into day-old rice with peas and soy sauce; stir until set.
When Volume Beats Grams
Some days you don’t want to weigh food. For most home recipes, using the count or spoon-measure conversions above keeps you within a few calories. Save the scale for baking or for tight macro goals.
Who Might Prefer Whole Eggs
If you want more vitamins and choline in the same portion, keep a yolk or two. For those on a low-fat plan, egg whites give flexibility: you can add fat from olive oil, cheese, or avocado in amounts that fit your target.
Storage And Safety
Keep raw whites cold. If you separate eggs, use the whites within a couple of days or freeze them in ice-cube trays for quick portions. Carton whites stay fresh to the printed date once opened if they’re kept chilled; always follow the label.
Equivalents For 1/2 Cup (Handy Table)
| Portion | Equals | Notes |
|---|---|---|
| 1/2 cup egg whites | ≈4 large whites | 1 large white = 2 tbsp (see AEB) |
| 1/2 cup egg whites | ≈8 tablespoons | Measure by spoon when no scale |
| 1/2 cup egg whites | ≈122 grams | Weigh for tight macros |
Cooking Losses And Pan Residue
Calories don’t vanish in the pan. You may see a small change on a kitchen scale after cooking due to water loss and bits that cling to the skillet. The nutrition in the portion you serve stays in the same range as the raw weight above.
Carton Egg Whites Vs. Fresh
Both give the same basic nutrition when unflavored. Carton whites are pasteurized, which is handy for no-cook uses like shakes. For whipping, fresh cold whites often give better volume; carton whites can whip well too, but they may take longer.
Simple Step-By-Step: Measure A Half Cup Fast
- Grab a liquid measuring cup with clear markings.
- Crack 4 large eggs and separate, or open a carton.
- Pour to the 1/2 cup line (or weigh 122 g).
- Cook right away, or cover and chill for later.
Calorie Math You Can Reuse
Want a custom portion? Multiply grams by 0.52 to get calories, or multiply by 0.109 to get protein grams. Example: 90 g of whites → 90 × 0.52 ≈ 47 calories and 90 × 0.109 ≈ 9.8 g protein. Once you try this shortcut a few times, it sticks.
Smart Pairings For Balance
On their own, egg whites bring protein without much else. Round out the plate with color and texture so the meal feels complete. Sauté peppers, onions, and zucchini in a slick of olive oil, then fold in your 1/2 cup of whites for a quick pan scramble. Add a spoon of salsa or a few slices of avocado for a fresh finish. For a carb source, try a small tortilla, a slice of whole-grain toast, or a cup of diced potatoes cooked in an air fryer. Each choice changes calories, so pick the one that fits your day…
Baking With Only Whites
Switching a recipe to whites can change structure, moisture, and browning. Whites set fast and dry out if heat runs high. When a cake calls for whole eggs, replacing one or two with 1/4 cup whites keeps volume while trimming calories. If a batter feels tight, whisk a tablespoon of neutral oil or plain yogurt into the wet mix. That keeps the crumb tender while your calorie line stays lean.
Label Reading Tips For Carton Whites
Plain cartons list only egg whites in the ingredient line. Some brands add a touch of calcium or a thin stabilizer to improve pour; these don’t change calories by much. Watch for flavored blends that include herbs, spices, or veggies in a base; the label will show a small bump in carbs or sodium. Serving sizes vary too: some use 3 tablespoons, others 1/4 cup. Match your log entry to the grams on the label to keep tracking clean.
Portion Control For Different Goals
Meal planning gets easier when you map one scoop to one outcome. Here are simple moves that start with the same half-cup base. Need a snack that carries you through the afternoon? Make an egg-white wrap and fill it with cottage cheese and sliced tomatoes. Want a bigger breakfast? Pair 1/2 cup of whites with 1 whole egg and a sprinkle of shredded cheese. Need a post-workout plate? Cook 1/2 cup of whites with leftover rice and edamame for a fast protein-carb combo.
Texture Tweaks Without Many Calories
Whites love moisture. Stir in a tablespoon of milk, kefir, or stock for softer curds in the pan. For a fluffy omelet, cover the skillet for the last minute so steam lifts the surface. Cheese adds flavor fast; a teaspoon of Parmesan carries strong taste for a minor calorie cost. Fresh herbs go a long way too. Chives, dill, parsley, and basil all fit right in.
Why Your Count Might Not Match An App
Nutrition apps pull from different databases. Some list 1 cup at 240 g, others at 250 g. That small gap shifts the half-cup calorie line a point or two. If you want every log to match, pick one source and stick to it. The method used in this guide comes from a gram-based approach tied to USDA numbers, so it stays steady across brands and recipes.
Recipe Ideas That Respect The Numbers
Five-Minute White Omelet
Heat a nonstick skillet with a light spray. Pour in 1/2 cup of whites. When the edges set, scatter chopped herbs, a spoon of feta, and a few cherry tomato halves. Fold and slide to a plate. Serve with toast or fruit for a fuller plate.
Bottom Line
For logging and meal prep, use this default: 1/2 cup of raw egg whites = about 63 calories and about 13 g protein. That single line will cover nearly every home recipe you’ll cook.
