Chinese Soup Cups: Easy Egg Drop Soup in Small Servings

Chinese soup cups are individual servings of egg drop soup, a light Chinese-style broth with silky egg ribbons, ginger, and scallions. This version is quick to make and easy to portion as a starter; recipes for egg drop soup vary from household to household and restaurant to restaurant.

Ingredients

6 cups (1.42 L) low-sodium chicken broth or stock
1 tablespoon (6 g) finely grated fresh ginger
2 scallions (about 30 g), thinly sliced; separate the white and green parts
2 tablespoons (16 g) cornstarch
¼ cup (60 ml) cold water
3 large eggs (about 150 g without shells)
1½ tablespoons (22 ml) regular or light soy sauce
2 teaspoons (10 ml) toasted sesame oil
¼ teaspoon (about 0.5 g) ground white pepper, or to taste
¼ teaspoon (1.5 g) fine salt, plus more only if needed

Instructions

Prepare the ingredients. Grate the ginger and slice the scallions, keeping their white and green parts separate. In a small bowl, whisk the cornstarch into the cold water until smooth. In another bowl, beat the eggs just until the yolks and whites are combined; a few streaks are fine. Having the slurry and eggs ready before the broth gets hot makes the final steps easier to manage.
Heat the broth and aromatics. Pour the broth into a medium saucepan and add the ginger and scallion whites. Set over medium-high heat and bring to a gentle simmer, which should take about 5 minutes. Avoid a vigorous boil: a steady simmer is enough to infuse the broth and helps prevent it from reducing too quickly.
Thicken the broth lightly. Stir the cornstarch mixture again, since it settles quickly, then slowly pour it into the simmering broth while stirring. Continue stirring for about 1 minute, then simmer for 2 minutes so the broth loses its chalky, raw-starch taste and becomes lightly silky. The soup should remain pourable, not thick like gravy.
Add the eggs in ribbons. Reduce the heat so the broth is barely simmering. Stir the soup in one direction to create a gentle current, then slowly drizzle in the beaten eggs in a thin stream over about 30 seconds. Let the eggs set for about 1½ minutes without vigorous stirring. Egg dishes should reach 160°F (71°C); check the soup with a food thermometer. This is the USDA FSIS safe minimum temperature for egg dishes.
Season and finish. Stir in the soy sauce, sesame oil, white pepper, and salt. Taste before adding extra salt, because broth and soy sauce vary in sodium. Take the pan off the heat and let the soup stand for 1 minute, then ladle it into six small heatproof cups or bowls and top with the scallion greens. The listed cooking time includes the broth heating, simmering, and brief finishing rest.

Tips

Keep the egg stream thin. Pour slowly while the broth moves gently; this makes delicate ribbons. If you pour in all the egg at once or boil the soup hard, you are more likely to get clumps or tough pieces. A fork or chopstick can help guide a fine stream from the bowl.
Use cold water for the slurry. Cornstarch mixes smoothly into cold water. If you stir it directly into hot broth, it can form lumps. Give the slurry another stir immediately before adding it, as the starch settles to the bottom while it waits.
Adjust the seasoning gradually. Low-sodium broth gives you more control. Add soy sauce first, taste, and then decide whether the measured salt is needed. White pepper has a distinct warm, earthy flavor; black pepper works as a substitute but tastes sharper and is more visible in the clear broth.
Plan the texture around serving. The soup thickens slightly as it stands, and the egg ribbons continue to firm up. If it gets thicker than you like, stir in a little hot broth or water. For serving guests, keep the soup in the saucepan and ladle it into warmed cups just before serving.

Serving Suggestions

Serve the soup hot in small cups as a first course or light side. Six portions are based on cups holding about 6 to 8 fluid ounces (180 to 240 ml), with a little room at the top to make carrying and sipping easier. If you are serving it alongside a full meal, smaller cups are practical; for a light lunch, use bowls and offer a larger portion.

Pair it with steamed rice, vegetable fried rice, or noodles, and add a plate of stir-fried greens, dumplings, or steamed vegetables for a more substantial spread. Keep the soup’s delicate flavor in mind when choosing other dishes: strongly seasoned or very spicy foods can overwhelm it. Put extra sliced scallion, a small dish of soy sauce, and chili oil on the table so guests can season their own portions. Use heatproof cups, and remind diners that the broth will be hot even when served in small amounts.

Variations

Make it vegetarian: Replace the chicken broth with vegetable broth. Choose a mild, savory one so it does not compete with the egg and ginger. The flavor will be a little less rounded than chicken-broth soup; a few drops of additional soy sauce can help, but taste before adding it.

Add vegetables: Stir in ½ cup (75 g) thawed corn or finely sliced mushrooms while the broth simmers. Allow mushrooms a few extra minutes to soften before thickening the soup. For quick-cooking spinach, add a small handful just before the eggs so it wilts without becoming too soft.

Use a different thickener or omit it: Arrowroot can replace cornstarch in the same amount, though it may produce a slightly clearer, more slippery texture. For a brothier cup, leave out the starch and water entirely; the egg ribbons will still add body, but the soup will be thinner.

Change the aromatics: A small pinch of ground white pepper can be omitted for a very mild soup, or a thin slice of fresh ginger can be simmered and removed before serving for a subtler ginger note. If toasted sesame oil is unavailable, use a neutral oil and finish with a few toasted sesame seeds; the soup will lose some of the oil’s pronounced nutty aroma.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered, shallow container. Keep the soup refrigerated at 40°F (4°C) or colder and use it within 3 to 4 days. The egg ribbons may become firmer and the broth may thicken as it sits, so stir gently before reheating. For best texture, store the soup in one container rather than dividing it into cups that may cool at different rates.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring gently until it reaches 165°F (74°C); check with a food thermometer. Avoid a hard boil, which can make the eggs rubbery. Add a splash of broth or water if the soup has thickened. You can freeze the soup in a freezer-safe container for up to 2 months, though the egg and cornstarch texture may change after thawing. Thaw it in the refrigerator and reheat to 165°F (74°C). Do not leave the soup at room temperature for more than 2 hours.

Frequently Asked Questions

What does “Chinese soup cups” mean in this recipe?
This recipe uses “Chinese soup cups” to describe individual cup-sized servings of Chinese-style egg drop soup. The soup itself is cooked in a saucepan, then ladled into small heatproof cups or bowls; the cups are serving vessels, not an edible wrapper.

Can I make the soup without cornstarch?
Yes. Skip both the cornstarch and the water, and follow the remaining steps as written. The broth will be thinner, but the egg ribbons still make it satisfying to sip. Do not add dry cornstarch directly to the hot soup if you change your mind; mix it with cold water first.

How do I get thin, wispy egg ribbons?
Beat the eggs until just combined and pour them slowly into broth that is gently simmering, not boiling. Stir the broth in one direction to form a mild current and drizzle the egg into that current. Leave it alone briefly to set; repeated stirring breaks the ribbons into smaller pieces.

Can I prepare it ahead for a party?
You can make the broth base, including the ginger, scallion whites, cornstarch, and seasonings, a day ahead and refrigerate it. Reheat the base, then add freshly beaten eggs shortly before serving and cook until the soup reaches 160°F (71°C). This keeps the egg ribbons fresher in texture than making the complete soup far ahead.

What can I use instead of soy sauce?
Use a gluten-free tamari if you need to avoid wheat, checking the label for the specific product. Coconut aminos can also work, but they are usually milder and sweeter, so add them gradually and taste the broth before adjusting salt. Avoid using both the full soy sauce amount and a full replacement amount at once.

Why did my egg drop soup turn cloudy or lumpy?
A little cloudiness is normal when cornstarch and eggs are in the broth. Large lumps usually mean the starch slurry was not smooth, was not stirred again before pouring, or the eggs were added too quickly. Next time, whisk the slurry just before use and stream the egg slowly into a gentle simmer rather than a rolling boil.
