Chinese Corn Soup: Easy, Silky Egg-Drop Soup

Chinese corn soup is a gently savory, slightly sweet soup made with corn, broth, and delicate ribbons of egg. This Chinese-style version uses ginger, scallions, and a little sesame oil for fragrance, and comes together quickly as a light starter or a simple meal; recipes vary across households and restaurants.

Ingredients

1 tablespoon neutral oil (15 ml), such as canola or vegetable oil
1 teaspoon finely grated fresh ginger (2 g)
2 scallions (about 30 g), thinly sliced; keep the white and green parts separate
4 cups low-sodium chicken broth (950 ml); vegetable broth works for a vegetarian soup
1 can cream-style corn, about 14.75 ounces (418 g)
1 cup corn kernels, fresh, frozen and thawed, or drained canned corn (165 g)
1 tablespoon regular or light soy sauce (15 ml)
⅛ teaspoon ground white pepper (about 0.3 g)
2 tablespoons cornstarch (16 g)
¼ cup cold water (60 ml), for the cornstarch slurry
2 large eggs (about 100 g without shells), lightly beaten
1 teaspoon toasted sesame oil (5 ml)
¼ teaspoon fine salt (about 1.5 g), plus more to taste

Instructions

Prepare the ingredients, about 15 minutes. Grate the ginger and slice the scallions, setting the green tops aside for serving. Measure the broth, corn, soy sauce, and seasonings. In a small bowl, whisk the cornstarch with the cold water until smooth. Beat the eggs in a separate bowl just until the whites and yolks are combined; avoid whipping in lots of air, which can make the ribbons foamy.
Soften the aromatics, 2 minutes. Set a medium saucepan or soup pot over medium heat and add the neutral oil. Add the grated ginger and the white parts of the scallions. Stir for about 2 minutes, until fragrant and softened, without letting the ginger brown. If it starts to sizzle sharply or darken, lower the heat.
Simmer the corn and broth, about 12 minutes. Pour in the broth, cream-style corn, corn kernels, soy sauce, white pepper, and salt. Stir to combine, then bring the mixture to a gentle simmer over medium-high heat, which takes about 4 minutes. Lower the heat and simmer for 8 minutes, stirring occasionally so the corn does not settle and catch on the bottom. Keep it at a steady, gentle bubble rather than a hard boil.
Thicken the soup, 2 minutes. Stir the cornstarch slurry again, since it can settle quickly, then pour it into the simmering soup while stirring steadily. Cook for about 2 minutes, until the broth looks glossy and lightly thickened. It should coat a spoon but still pour easily. If you prefer a thinner soup, use only part of the slurry; you can add more after mixing it again.
Make the egg ribbons, about 3 minutes. Reduce the heat to low so the soup is barely simmering. Stir the soup in one direction to create a slow-moving current, then pour in the beaten egg in a thin, steady stream. Wait a few seconds before stirring gently once or twice; this gives the egg time to form soft ribbons instead of breaking into tiny flecks. Continue cooking and stirring until the egg is fully cooked. For food safety, egg dishes should reach 160°F (71°C); the USDA FSIS safe minimum temperature applies here, so check the soup with a food thermometer after stirring.
Finish and taste, 1 minute. Turn off the heat and stir in the sesame oil and most of the scallion greens. Taste the soup and add a little more salt or soy sauce if needed. Ladle into warm bowls and scatter the remaining scallions over the top.

Tips

Stir the slurry immediately before using it. Cornstarch sinks to the bottom of the bowl within minutes. If it goes into the pot separated, the soup may thicken unevenly or leave a starchy layer behind. Keep stirring as you pour it in.
Keep the simmer gentle when adding egg. A rolling boil breaks the egg into small, tough pieces and can make the broth cloudy. A slow circular current and a thin stream of egg create more distinct, tender ribbons.
Choose the broth to suit the soup. Low-sodium broth makes it easier to control salt, especially because soy sauce also seasons the pot. For a vegetarian version, use vegetable broth and confirm that the soy sauce is suitable for your needs; the result is a little less savory but still full of sweet corn flavor.
Adjust thickness gradually. Cream-style corn adds body, and the slurry thickens the soup further. Start with the listed amount, then decide whether you want more body before adding extra. Adding too much cornstarch can make the soup feel gluey, particularly after it cools.

Serving Suggestions

Serve Chinese corn soup hot in small bowls as a first course alongside a larger Chinese-style meal. It pairs well with steamed rice, vegetable stir-fry, dumplings, or noodles, and its mild sweetness balances dishes with chili, garlic, or a more assertive soy-based sauce. For a light lunch, make the soup the main dish and add a side of rice or a simple plate of greens.

Finish each bowl with a few scallion greens and, if you like, a small extra drop of toasted sesame oil. A pinch of white pepper gives it a warm, quiet heat without changing the soup’s pale color. Put chili crisp or sliced fresh chili on the table rather than adding it to the whole pot, so everyone can season their own portion.

Variations

Make it vegetarian. Replace the chicken broth with vegetable broth. For extra substance, add ½ cup (about 80 g) of diced soft tofu during the final few minutes of simmering. The tofu makes the soup more filling while keeping its gentle flavor; add it carefully so the cubes remain intact.

Add chicken. Stir in 1 cup (140 g) of cooked, shredded chicken after thickening the soup and let it heat through before adding the egg. If cooking raw chicken specifically for this recipe, cook it separately or in the broth until a food thermometer registers 165°F (74°C), the USDA FSIS safe minimum for poultry, then shred it. Using already-cooked chicken is a convenient way to use leftovers.

Use fresh or frozen corn. Cream-style corn gives the soup its familiar thick, sweet base. If it is unavailable, blend 1½ cups (about 250 g) of corn kernels with ½ cup (120 ml) of broth until mostly smooth, then add another ½ cup (80 g) of whole kernels. This homemade substitute is less creamy and may need a little more slurry to reach the same consistency.

Change the seasoning. White pepper is traditional in many Chinese-style soups because it adds warmth without visible dark flecks. If you cannot find it, use a small pinch of black pepper; the taste is slightly sharper and the specks will show. A few drops of rice vinegar at the table can brighten a bowl, but add it to individual servings rather than the pot.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. The soup keeps for 3 to 4 days in the refrigerator. Its texture may become thicker as the cornstarch cools, and the egg ribbons may soften, but this is normal. Stir in a splash of broth or water when reheating if it has thickened more than you like.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring often, until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS safe temperature for reheated leftovers. Avoid a vigorous boil, which can toughen the egg and make the soup less smooth. You can also microwave a serving in a covered, microwave-safe bowl, stirring once or twice during heating and checking the temperature in several places. Freezing is possible, but the egg and cornstarch can turn grainy or watery after thawing, so refrigeration is better for this recipe.

Frequently Asked Questions

Can I make Chinese corn soup without cream-style corn?

Yes. Blend some regular corn with broth to create a thick base, as described in the variations, then add whole kernels for texture. Cream-style corn is convenient and contributes sweetness and body, so a homemade blend may taste less sweet and need a little extra thickening. Add cornstarch slurry a little at a time until the soup is lightly glossy.

How do I get long egg ribbons instead of tiny pieces?

Keep the soup at a gentle simmer, stir it into a slow current, and pour the beaten egg in a thin stream. Give it a few seconds to set before stirring gently. If the soup is boiling hard, the egg will break apart more readily; if you stir vigorously as soon as it lands, the ribbons will also fragment.

Is Chinese corn soup usually made with chicken broth?

Chicken broth is a common choice for a savory base, but recipes vary. Vegetable broth works well when you want a vegetarian soup, and some versions include cooked chicken while others rely on corn and egg alone. Use a low-sodium broth if possible so you can adjust the final seasoning without the soup becoming too salty.

Can I prepare it ahead of time?

You can make the soup a day ahead and refrigerate it promptly, but the texture is best when freshly made. If planning ahead, you can prepare the sliced scallions, measured ingredients, and slurry ingredients in advance; whisk the cornstarch and water together just before adding them. Reheat the finished soup gently to 165°F (74°C), stirring as it warms.

Why did my soup turn out too thick?

It may have simmered longer than intended, or the slurry may have been added all at once when a thinner texture would suit you better. Stir in warm broth or water a few tablespoons at a time until it loosens. Remember that cornstarch thickens more as the soup cools, so judge the consistency while it is hot and still easy to stir.
