Egg Drop Soup with Bok Choy and Mushrooms
I make this soup when I want something light, restorative, and fast enough for a weeknight. It’s a clear, gently fragrant broth brightened by tender baby bok choy, browned mushrooms, and silky ribbons of egg. The aromatics—lemongrass, ginger, garlic—give it a subtle lift without turning it fussy.
What I love most is how adaptable the bowl is. It reads elegant at the table and humble at the stove. The technique is simple: build a flavorful broth, sauté the veg, thicken gently, and introduce eggs so they form fine ribbons. There’s comfort in the straightforwardness of that process.
Below you’ll find the exact ingredients and steps I use, practical equipment notes, allergy-friendly swaps, and quick troubleshooting. If you follow the order here you’ll have a clean, fragrant soup that’s great as a starter or a light main.
Gather These Ingredients
Ingredients
- 2 tablespoons olive oil — split into two portions; one for the broth aromatics and one for sautéing the vegetables.
- 2 cinnamon sticks — adds warm, background sweetness to the broth.
- 1 star anise — imparts a faint licorice note that rounds the aromatics.
- 2 inch stalks lemongrass, halved and chopped into 3 pieces — crushed and simmered for citrusy fragrance.
- 1 (2-inch) piece ginger, sliced into rounds — sharp, warming flavor; remove before serving.
- 3 cloves garlic, minced — builds savory depth in the broth.
- ½ teaspoon red pepper flakes — optional; adds a gentle heat if you like a touch of spice.
- 2 bulbs baby bok choy — trimmed and roughly chopped; the tender greens and stems add texture and color.
- 4 mushrooms, chopped — I use cremini or button; they brown nicely and add umami.
- 4 cups low-sodium chicken broth — the base of the soup; low-sodium lets you control seasoning.
- 2 tablespoons liquid aminos — to taste; provides umami and saltiness without overpowering the aromatics.
- 3 large eggs — beaten and turned into ribbons for silkiness.
- 1 ½ tablespoons cornstarch — separated; used to make a slurry and to bind with the eggs for texture.
- 1 bunch green onion, chopped — for finishing; adds freshness and a mild bite.
Method: Egg Drop Soup with Bok Choy and Mushrooms
- Prepare ingredients: halve and chop each lemongrass stalk into 3 pieces, slice the ginger into rounds, mince the garlic, trim and roughly chop the baby bok choy, and ensure the mushrooms are chopped. Measure out 1 tablespoon cornstarch and 1/2 tablespoon cornstarch separately; beat the 3 eggs in a small bowl and set aside.
- Heat 1 tablespoon olive oil in a large saucepan or pot over medium-high heat. Add the 2 cinnamon sticks, 1 star anise, the prepared lemongrass, the sliced ginger, the minced garlic, and the optional ½ teaspoon red pepper flakes. Cook, stirring frequently, until the spices are very fragrant, about 3 minutes.
- Add the 4 cups low-sodium chicken broth and 2 tablespoons liquid aminos to the pot and stir. Bring the mixture to a full boil, then reduce the heat to low, cover, and simmer for 15 to 20 minutes.
- While the broth simmers, heat the remaining 1 tablespoon olive oil in a separate skillet over medium-high heat. Add the chopped mushrooms and the prepared baby bok choy and sauté until browned and softened, about 5 to 8 minutes. Transfer the cooked vegetables into the simmering broth.
- Taste the broth and add more liquid aminos if desired. Use a slotted spoon to remove and discard the ginger rounds, cinnamon sticks, star anise, and lemongrass pieces.
- Make the cornstarch slurry: stir 1 tablespoon cornstarch into a small bowl, add about 1/3 to 1/2 cup of the hot broth from the pot, and whisk until fully dissolved. Return the pot to a very gentle simmer and stir the slurry into the broth.
- Add the remaining 1/2 tablespoon cornstarch to the beaten eggs and whisk until combined.
- With the broth at a gentle simmer, slowly pour the egg-and-cornstarch mixture into the pot through the tines of a fork (or a small sieve), pouring a little at a time and whisking the broth gently between pours to create thin egg ribbons.
- Keep the soup at low heat and whisk occasionally for a couple of minutes, until the egg is fully set and the soup has slightly thickened. Turn off the heat.
- Ladle the soup into bowls, garnish with the chopped green onion, and serve.
What You’ll Love About This Recipe
This bowl is surprisingly complex for how little time it takes. The slow-simmered aromatics—lemongrass, ginger, star anise—transform plain broth into something fragrant without any hard work. Browning the mushrooms and softening the bok choy in a skillet first builds caramelized flavor that the broth alone can’t achieve.
The egg technique is forgiving. Combining a little cornstarch into the beaten eggs helps produce thin, stable ribbons rather than wispy, fragile threads. The resulting texture is silky and satisfying. It’s a great weeknight solution when you want comfort without heaviness.
Finally, it scales easily. Double the broth and vegetables for guests, or make a concentrated version for a quick lunchtime bowl. It’s both elegant and everyday—rarely do you get both.
Allergy-Friendly Substitutes
- Chicken broth — substitute low-sodium vegetable broth to make the recipe vegetarian; the broth will be lighter, so increase mushrooms for more umami.
- Liquid aminos — use low-sodium soy sauce or tamari if you need a gluten-free option; tamari keeps it gluten-free but preserves the deep flavor.
- Eggs — for an egg-free variation, skip the egg step and use the full 1 ½ tablespoons cornstarch as a slurry to slightly thicken the broth; the result will be a silky vegetable soup rather than an egg-drop texture.
- Cornstarch — arrowroot can replace cornstarch at a 1:1 ratio; it gives a clearer finish if you prefer that look.
Before You Start: Equipment
- Large saucepan or pot — for simmering the aromatics and broth. Choose one with a lid so you can control simmer time.
- Separate skillet — for sautéing the mushrooms and bok choy to build flavor before adding them to the broth.
- Small bowl and fork/whisk — to beat the eggs and mix each cornstarch portion. A fork also doubles as a tool when pouring the egg for ribbons.
- Slotted spoon — handy for removing lemongrass, ginger slices, star anise, and cinnamon sticks before serving.
- Measuring spoons/cups — precise amounts matter for the cornstarch and liquid aminos; have them ready.
Steer Clear of These
- Boiling when adding eggs: If the broth is boiling hard the moment you add the egg mixture, the ribbons will break into small bits. Keep it at a gentle simmer.
- Skipping the slotted spoon step: Forgetting to remove whole aromatics—lemongrass, ginger rounds, star anise, cinnamon—can leave a chunkier, bitter mouthfeel or an overly intense spice bite in the finished soup.
- Over-thickening: Adding too much cornstarch or not dissolving it properly results in a pasty texture. Mix with hot broth first and add slowly.
Spring to Winter: Ideas
- Spring: Add a handful of thinly sliced snow peas or pea shoots at the end for a bright, fresh crunch.
- Summer: Swap mushrooms for a mix of shiitake and oyster, and finish with a squeeze of lime for brightness.
- Fall: Use a richer broth, add sliced shallots with the mushrooms, and stir in a touch of toasted sesame oil for warmth.
- Winter: Increase the ginger and red pepper flakes slightly for heat, and add thinly sliced carrots to the sauté for extra body.
Little Things that Matter
Timing matters with the aromatics. Give the lemongrass, cinnamon, and ginger those initial three minutes in oil so they bloom properly—this step is cheap effort for huge payoff. When browning mushrooms, resist overcrowding the pan. Work in one or two batches if needed so they caramelize instead of steam.
When you make the slurry, use hot broth rather than cold water; it dissolves the cornstarch more smoothly. And when pouring the egg, a fork gives a finer stream than pouring directly from a bowl. If you want slightly thicker egg ribbons, pour a bit more slowly and let each addition settle before you whisk.
Refrigerate, Freeze, Reheat
Refrigerate
- Storage: Cool the soup to room temperature, then store in an airtight container for up to 3 days. The bok choy will soften over time.
Freeze
- Not ideal: Egg ribbons change texture after freezing and thawing. If you must freeze, omit the eggs and freeze the broth with vegetables for up to 2 months. Add freshly beaten eggs when reheating.
Reheat
- Gently: Reheat on low to medium heat. If the soup thickened in the fridge, add a splash of water or broth and bring to a gentle simmer. If you froze without eggs, whisk fresh eggs with the remaining ½ tablespoon cornstarch and add them using the ribbon method when the soup is warm.
Reader Questions
- Q: Can I use dried lemongrass or lemongrass paste?
A: Dried lemongrass will work but is less vibrant. Use a smaller quantity and taste as you go. Paste is more concentrated—start with half the amount and adjust. - Q: My eggs clumped—what went wrong?
A: That usually happens if the broth is boiling or if the egg mixture is poured too quickly. Keep a gentle simmer and pour slowly through a fork or small sieve, whisking lightly between pours. - Q: Can I make this vegan?
A: Yes—use vegetable broth, replace liquid aminos with tamari or coconut aminos, and skip the eggs. Stir in extra cornstarch slurry to reach a silky texture or add silken tofu at the end for protein. - Q: How to adjust saltiness?
A: Liquid aminos are salty and savory. Start with the 2 tablespoons listed and taste after simmering the aromatics. Add more in small increments if needed.
