Chicken and corn soup
This is the takeout favourite made lighter and brothier. Restaurant chicken and corn soup is usually thickened with a cornstarch slurry; this version skips it, so you get a clear, gingery broth packed with sweet corn and tender chicken, at about 300 kcal and 34 g of protein a bowl. Eight ingredients, one pot, 20 minutes.

The science hook is how fast egg sets. Egg proteins firm up well below boiling point, so a hot broth turns a thin pour of beaten egg into soft strands in seconds. The minute of simmering afterwards makes sure every ribbon is fully cooked through.
The science: why this works
- Egg whites begin to set around 62–65°C (144–149°F) and yolks around 65–70°C (149–158°F). Simmering broth sits far above that, so thin threads firm up within seconds, and the extra minute carries them past 71°C (160°F), the safe point for egg dishes.
- The ginger goes in with the cold broth, so it infuses the whole pot as it heats. As it simmers, some of ginger's sharp gingerols turn into zingerone, a milder, sweeter compound, which gives a rounded warmth rather than a raw bite.
- Without cornstarch, the broth stays thin and clear, and the egg ribbons drift and settle instead of hanging suspended the way they do in takeout versions. Starch-thickened broth also cushions the egg into fluffier clouds, which is why the variation below changes the texture so much.
- Frozen sweetcorn is usually a high-sugar variety frozen within hours of picking. As it simmers, some of that sugar dissolves into the broth, balancing the salty soy sauce and giving the soup its gently sweet character.
- Soy sauce's toasty, fermented aroma comes from volatile compounds that fade with long boiling, so stirring it in at the very end means you actually smell it in the bowl.
Why the egg forms ribbons
Egg proteins set quickly in hot broth. Pouring the egg in a thin stream while stirring in one direction spreads it into thin strands before it can clump, which makes silky ribbons. Slow, gentle heat gives soft, silky results, while harsh heat makes proteins tight and dry.

Tiny pieces of chicken cook through in just 8 minutes and stay tender in the broth. Cooking to 165°F (74°C) with no pink keeps it safe without drying it out. Even pieces mean even cooking, so nothing is raw while something else is overdone.
Learn: Cut food the same size →Why the broth just simmers
A gentle simmer cooks the chicken while keeping the broth clear. A rolling boil would toughen the meat and break the egg into small bits. Keep the heat low enough that only small bubbles rise. This also makes the broth taste cleaner and look clearer.

Ingredients
Makes 2 servings
- 200 gchicken breast, finely diced
- 200 gfrozen corn
- 750 mlchicken broth
- 2eggs
- 1 tspgrated ginger
- 1 tbspsoy sauce
- 2green onions, sliced
- Black pepper
Method
Tips for the best result
- Beat the eggs with a fork for a good 30 seconds, until no stringy streaks of white remain, so they pour in a smooth, even stream.
- Pour the egg through the tines of a fork held over the pot for the finest, most delicate threads.
- After pouring, count to 10 before you stir again so the ribbons have time to set.
- Slice the green onions on a thin diagonal and keep the white and green parts separate: stir the whites in with the soy sauce and scatter the greens on top.
- Grate the ginger on a fine grater straight over the pot so none of its juice is lost.
- Dice the chicken while it's still very cold, or after 15 minutes in the freezer, for neat 1 cm cubes.
Mistakes to avoid
- Under-beating the eggs — streaks of white set into rubbery clumps; beat until the egg is one even yellow colour.
- Stirring straight after the egg goes in — it shreds the strands into cloudy specks; wait about 10 seconds first.
- Pouring the egg into broth that has stopped bubbling — lukewarm broth sets it slowly into murky, soft blobs; make sure the soup is gently simmering first.
- Leaving the soup bubbling after the egg has set — the ribbons shrink and toughen; serve as soon as the minute is up.
Variations and swaps
- Make it restaurant-thick: stir 1 tbsp cornstarch into 2 tbsp cold water and add it to the simmering soup before the egg.
- Finish with a few drops of toasted sesame oil and a pinch of white pepper for a classic takeout flavour.
- Use shredded leftover roast chicken instead of raw, adding it with the corn just to heat through.
- Add cubes of silken tofu or a handful of baby spinach in the last 2 minutes.
- Use tamari labelled gluten-free, and check the broth label, for a gluten-free bowl.
- Swap the chicken breast for shrimp, cooked until pink for about 3 minutes.
Storing and reheating
Refrigerate within 2 hours (1 hour above 32°C/90°F) at 4°C (40°F) or below for 3–4 days. Reheat on the stove to a rolling boil, stirring gently, and expect the egg ribbons to firm up a little. Add fresh green onion after reheating, since the old ones go limp and dull. For freezing, set some aside before the egg goes in: frozen at −18°C (0°F) it keeps 2–3 months, then thaw in the fridge, bring to a boil and pour in freshly beaten egg. Frozen egg ribbons turn spongy, so avoid freezing the finished soup.
Chicken and corn soup: questions
Is this a Cantonese dish?
It's in the style of Cantonese chicken and sweetcorn soup, a Chinese restaurant classic. This version is lighter because it skips the usual cornstarch thickener.
Can I use canned corn instead of frozen?
Yes. Drain canned sweetcorn well and add it with the chicken; it only needs to heat through.
Why is my broth cloudy?
Usually the soup was stirred too soon or too hard after the egg went in, breaking it into tiny specks. Wait a few seconds after pouring, then stir gently.
How do I make it thick like takeout?
Add a cornstarch slurry: 1 tbsp cornstarch mixed into 2 tbsp cold water, stirred into the simmering soup before the egg. It thickens within a minute.
Is it gluten-free?
Not as written, because soy sauce contains wheat. Use gluten-free tamari and a broth labelled gluten-free to make it so.
Can I freeze it?
Freeze it before adding the egg, for up to 3 months. Finished soup with egg ribbons turns spongy after thawing.
How do you make egg drop soup ribbons?
Pour beaten egg slowly into simmering broth while stirring in one direction. A thin stream makes thin, silky ribbons.
Can I use cream corn?
Yes, cream-style corn makes it thicker and sweeter. Use less broth if you do.
Is the soup safe with just 1 minute of egg cooking?
Yes, as long as the broth is simmering hot and the egg is fully set. The strands should look firm and opaque.
