This egg drop soup uses a cornstarch slurry to lightly thicken the broth, which is what gives the egg ribbons somewhere to float instead of sinking and clumping. A finishing drizzle of scallion–ginger oil adds real fragrance without a separate cooking step. The whole thing is done in 25 minutes and dirties one pot and one small bowl.
About the ingredients
- White pepper: This is worth buying if you don’t have it. Black pepper works in a pinch, but white pepper has a sharper, more aromatic heat that’s standard in this soup — a small jar lasts months.
- Cornstarch: The slurry is what creates that slightly glossy, thickened broth. Don’t skip it or substitute flour; flour makes the broth cloudy and starchy-tasting rather than silky.
- Broth: Chicken broth is the standard base here. Low-sodium gives you more control over the final salt level, which matters because soy sauce and seasoning get added later.
- Scallion–ginger oil: This is just oil warmed with aromatics — it’s not a separate recipe. Use a neutral oil like avocado or vegetable; olive oil will compete with the ginger.
The technique that matters
The egg pour is the one step that determines whether you get silky ribbons or rubbery scrambled eggs. The broth needs to be hot but not at a rolling boil — a gentle simmer with small bubbles is right. Stir the broth in a slow circle before you pour, then stream the beaten eggs in a thin, steady drizzle from a liquid measuring cup with a spout. Moving the cup slowly around the edge of the pot as you pour gives you longer, more even ribbons. Once the eggs hit the broth, stop stirring immediately and let them set for about 15 seconds before you touch them. Stirring too soon breaks the ribbons into small bits.
Mistakes to avoid
- Adding the slurry to cold broth: The cornstarch needs hot liquid to activate. Bring the broth to a simmer first, then stir in the slurry — not the other way around. If the broth isn’t hot enough, the soup will stay thin.
- Skipping the slurry stir right before pouring: Cornstarch settles fast. Give the slurry a quick re-stir in the bowl right before you add it to the pot, or you’ll pour in mostly water and leave a starch paste behind.
- Overcrowding the pot with eggs too fast: Dumping the eggs in all at once drops the broth temperature and produces thick, uneven curds. A slow, thin pour is the fix.
- Seasoning before tasting: Broth brands vary a lot in sodium. Add soy sauce and salt gradually at the end and taste as you go — it’s easy to over-salt this soup because the volume is small.
- Reheating on high heat: The egg ribbons tighten and turn rubbery fast. Use low heat and warm the soup slowly, or use short 30-second microwave intervals.
Leftovers and make-ahead
Leftover soup keeps in a sealed container in the fridge for up to 3 days. The broth will thicken as it sits because of the cornstarch — that’s normal. Thin it with a splash of broth or water when reheating. Skip the freezer; egg ribbons turn spongy and grainy after freezing and thawing, and it’s not worth it for a soup this quick to make fresh. If you want to get ahead on a busy night, you can mix the cornstarch slurry and beat the eggs up to a day in advance and keep them covered in the fridge — that cuts the active cook time to under 10 minutes.
Silky Egg Drop Soup with Scallion–Ginger Drizzle
Equipment
- 3–4 qt saucepan or soup pot
- Ladle
- Whisk
- Small bowl (for slurry)
- Liquid measuring cup with spout
- Measuring cups and spoons
- Chefs Knife
- Cutting board
- Fine-mesh strainer or slotted spoon
- Heatproof bowl (for oil drizzle)
- Instant-read thermometer (optional)
Ingredients
For the Soup
- 2 tbsp cornstarch For a clear, lightly glossy broth; Argo or Bob’s Red Mill work well.
- 3 tbsp cool water To make the cornstarch slurry; cool water prevents clumping.
- 3 large eggs Room temperature yields smoother ribbons.
- 1 tsp toasted sesame oil Whisked into eggs for aroma; plus more to finish if desired.
- ½ tsp fine sea salt Adjust to taste, especially if broth is unsalted.
- 6 cups low-sodium chicken broth Homemade if possible; quality boxed broth like Kettle & Fire or Pacific.
- 1 inch piece fresh ginger, thinly sliced No need to peel if the skin is smooth and clean.
- 2 cloves garlic, lightly smashed Adds a soft background warmth.
- 4 whole scallions, trimmed (whites and greens separated) Whites for the broth; greens for garnish.
- 1 tbsp low-sodium soy sauce Kikkoman Less Sodium or Pearl River Bridge light soy.
- 1 tbsp Shaoxing wine (optional) Adds depth and a touch of sweetness.
- ½ tsp ground white pepper Classic peppery fragrance; use freshly ground if possible.
- 1 pinch ground turmeric (optional) Purely for a warm golden hue; keep light.
Scallion–Ginger Drizzle (Optional)
- 2 tbsp neutral oil (grapeseed or canola) Heat for a quick aromatic oil.
- 1 tsp fresh ginger, finely grated Use a microplane for a fine grate.
- 1 whole scallion, very thinly sliced Green parts preferred for color.
- 1 pinch red pepper flakes (optional) For a gentle heat.
Instructions
- Mix the slurry (2 minutes). In a small bowl, whisk together the cornstarch and cool water until perfectly smooth and no powder remains. Set aside; it should look slightly milky and pourable.
- Beat the eggs (2 minutes). In a spouted measuring cup, whisk the eggs with the toasted sesame oil and a small pinch of the salt just until combined—avoid frothy bubbles for the most delicate ribbons.
- Build an aromatic broth (5 minutes). In a 3–4 qt pot, combine the chicken broth, ginger slices, smashed garlic, and the white parts of the scallions. Bring to a lively simmer over medium-high heat (about 190–200°F / 88–93°C). You should smell ginger’s citrusy perfume and see gentle bubbles at the edges.
- Strain or remove aromatics (30 seconds). Use a slotted spoon to lift out the ginger, garlic, and scallion whites, or strain the broth through a fine-mesh strainer back into the pot. Return to medium heat.
- Season the broth (1 minute). Stir in the soy sauce, Shaoxing wine (if using), white pepper, and the optional pinch of turmeric for color. The aroma should be savory with a peppery lift.
- Lightly thicken (1–2 minutes). Bring the broth back to a gentle simmer (185–195°F / 85–90°C). While whisking in a smooth circle, slowly drizzle in the cornstarch slurry. Simmer just until the broth is lightly glossy and coats the back of a spoon. If it thickens too much, whisk in 1–2 tbsp hot water.
- Create silky egg ribbons (2 minutes). Reduce heat to low so the surface is steaming but not boiling (about 175–185°F / 80–85°C). With a ladle, gently stir the broth in one direction to form a slow whirlpool. From 8–10 inches above the pot, pour the beaten eggs in a thin, steady stream, maintaining the swirl. Pause 10–15 seconds to set, then give a gentle stir to reveal long, delicate strands.Technique alternatives: Pour eggs through the tines of a fork or chopsticks for extra-fine threads; or use a measuring cup with the smallest stream you can manage. Avoid vigorous stirring, which breaks the ribbons.
- Finish and season (1 minute). Taste and adjust with the remaining salt as needed. Off the heat, swirl in an extra few drops of sesame oil if you love its aroma. Ladle into warmed bowls and top with the green scallion slices.
- Optional scallion–ginger drizzle (3 minutes, can be done while the broth simmers). Place the grated ginger and thinly sliced scallion in a heatproof bowl. In a small pan, heat the neutral oil over medium until it shimmers and a scallion test slice sizzles on contact (about 320–335°F / 160–170°C). Carefully pour the hot oil over the aromatics—they should hiss and release a vivid fragrance—then stir in a pinch of red pepper flakes. Spoon 1/2 to 1 tsp over each bowl.
Notes
Lisa’s Tips
- Broth quality rules: A clean, flavorful broth is everything. If using boxed, choose low-sodium and finish with salt yourself.
- Slurry smoothness: Whisk the cornstarch right before adding—starch settles quickly. Arrowroot works in a pinch; use 1 tbsp + 1.5 tbsp water for a similar light body.
- Heat control: Silk, not scramble—keep the broth just below a boil when streaming eggs.
- Color cues: A tiny pinch of turmeric adds a restaurant-golden hue without altering flavor.
- Dietary swaps: Use vegetable broth and a dash of mushroom powder for a vegetarian version. For gluten-free, swap tamari for soy sauce and verify broth is gluten-free.
- Extras: A handful of sweet corn kernels or silken tofu cubes are classic, fast add-ins.

Serving Suggestions
- Ladle into warmed white bowls to showcase the golden broth and jade-green scallions. The ribbons should be pale and distinct, floating like petals.
- Finish with a few drops of sesame oil and the scallion–ginger drizzle. Serve with quick smashed cucumber salad or steamed jasmine rice. Pair with jasmine tea or a crisp Riesling.
Culinary Context
Known as “egg flower soup,” this dish is a weeknight staple across Chinese households and restaurants alike—humble, restorative, and endlessly adaptable. I first learned the ribbon technique from a Cantonese cook who swore by pouring from high for the longest strands—he was right.Optional Advanced Instructions
- Make-ahead: Infuse and strain the broth up to 2 days ahead; reheat to a gentle simmer before thickening and adding eggs.
- Parallel prep: While the broth infuses (Step 3), slice scallions and grate ginger; make the drizzle (Step 9) as the slurry sets (Step 1).
- Beginner alternative: If streaming from a height feels risky, let the broth sit still and pour the eggs through a fork held just above the surface, moving slowly in a spiral.

Frequently asked questions
Can I make this vegetarian?
Yes — swap the chicken broth for a good vegetable broth and the soup is fully vegetarian. Look for a vegetable broth that isn’t too sweet; mushroom-based broths work especially well here because they have a savory depth that holds up to the ginger and white pepper.
Why did my eggs turn into chunks instead of ribbons?
The broth was most likely too hot or you poured the eggs too fast. Pull the pot off direct heat for 30 seconds before you pour, and drizzle the eggs in a slow, thin stream while stirring the broth gently in one direction — skip the garnish and focus on the pour, it’s the only part that needs your full attention.
Do I have to use a liquid measuring cup to pour the eggs?
No, but it helps because the spout gives you a controlled, thin stream. A ladle with a small pour or even a zip-lock bag with a tiny corner snipped off works fine — the goal is just a slow, steady drizzle rather than dumping the eggs in all at once.
