Ingredients for chinese scallop soup
A delicate balance of fresh aromatics and premium sea scallops creates this restaurant-worthy soup.
| Ingredient | Amount | Notes |
|---|---|---|
| Dry Sea Scallops 🦪 | 1 ½ lb | Pat dry, side muscles removed |
| Fresh Ginger Root 🧅 | 3 tbsp | Thinly sliced, peeled |
| Lemongrass Stalks 🌿 | 4 whole | Bruised, cut into 2-inch pieces |
| Star Anise Pods 🌶️ | 2 whole | Lightly crushed |
| Green Onions 🧅 | 2 whole | White and green parts separated |
| Garlic Cloves 🧄 | 4 cloves | Minced |
| Light Soy Sauce 🍶 | 2 tbsp | Kikkoman preferred |
| Sesame Oil 🫒 | 1 tbsp | Toasted, for finishing |
| Water 💧 | 4 cups | Filtered or spring water |
| Cornstarch 🌾 | 1 tbsp | For velvety scallop texture |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Peppercorns 🌶️ | ¼ tsp | Freshly cracked |
| Sesame Seeds 🥜 | 1 tsp | Toasted, for garnish |
The scallops are the star, so buy them fresh—look for plump, translucent ones with no fishy odor. Asian markets often carry the best quality, but high-end grocery stores like Whole Foods or Trader Joe's usually have good options too. Pat them dry thoroughly before cooking to prevent broth cloudiness. For lemongrass, grab the thick stalks—they're more flavorful. Star anise should be whole and aromatic; if it smells stale, replace it. Ginger should be firm with no soft spots, and garlic cloves should be plump and free of sprouts.
No fresh lemongrass? Lemongrass paste works in a pinch (use half the amount), though fresh is ideal. Substitute 1 tsp lemongrass powder if needed, but the flavor won't be as vibrant. For star anise, 1/2 tsp ground anise can replace one pod, but the whole pods infuse better. The cornstarch is crucial—it creates that signature silky texture. If you don't have it, arrowroot powder works too. For soy sauce, tamari is a gluten-free alternative. The sesame oil should be toasted—regular sesame oil lacks that nutty depth.
This soup reheats beautifully, but scallops are best served fresh. Store leftovers in an airtight container for up to 2 days—the broth actually improves overnight. For longer storage, freeze for 3 months. Garnish with fresh green onions and sesame seeds just before serving to preserve their freshness. The soup pairs perfectly with steamed jasmine rice, which absorbs the fragrant broth beautifully. Double the recipe for a crowd—just scale all ingredients proportionally.
Why You'll Love This Recipe
- No-Chop Needed: I swear, the scallops just need a quick soak—no dicing, no fuss. The ginger and lemongrass get a rough chop, but even that’s optional if you’re in a rush. Honestly, I’ve made this with pre-minced ginger from a jar and it still tastes like a Michelin-starred moment.
- Umami Bomb: That star anise and ginger? They turn this soup into pure flavor gold. The scallops soak up the aroma while staying tender, and the lemongrass adds this bright, citrusy kick that cuts through the richness. It’s the kind of taste that makes you go back for seconds without even thinking.
- Weeknight to Dinner Party: Same recipe, different vibes—serve it steaming in mugs for a lazy Tuesday, or pour it into a pretty bowl with crispy wonton strips for guests. Between us, I’ve had this at both my kitchen table and a holiday spread, and no one ever questions how little effort it took.
- Leftovers That Don’t Suck: Unlike so many soups, this one actually improves the next day. The scallops get even more tender, and the broth deepens in flavor. I keep a batch in the fridge for those nights when I’m too tired to cook—just reheat, garnish with green onions, and boom. Instant dinner, no guilt.
Step-by-step instructions for Chinese scallop soup
Here's how to create a velvety ginger-lemongrass broth with perfectly silky scallops.
Prepare the Aromatics and Scallops
Start by thoroughly cleaning the 1.5 lb dry sea scallops under cold water and patting them completely dry with paper towels. Remove any side muscles if they haven't been prepped. In a small bowl, combine the 3 tbsp fresh ginger root (thinly sliced) and 4 whole lemongrass stalks (bruised and cut into 2-inch pieces). Lightly crush the 2 whole star anise pods and set aside.
Separate the 2 whole green onions into white and green parts, mincing the white portions. Peel and mince the 4 cloves garlic cloves. This preparation ensures all aromatics are ready to infuse the broth simultaneously, creating a harmonious flavor base.
Build the Fragrant Broth
In a large pot, combine the 4 cups water, ginger-lemongrass mixture, star anise, minced green onion whites, garlic, 2 tbsp light soy sauce, 1 tsp salt, and 0.25 tsp black peppercorns. Bring to a boil over medium-high heat, then immediately reduce to a simmer. Let it cook uncovered for 15 minutes to allow the aromatics to fully infuse the broth.
Strain the broth through a fine-mesh sieve into a clean pot, pressing gently on the aromatics to extract maximum flavor. Discard the solids. The broth should now have a vibrant golden color and a rich, aromatic scent—this is your foundation for the soup.
Create the Velvety Scallop Texture
In a small bowl, whisk together the 1 tbsp cornstarch with 2 tablespoons of the strained broth until completely dissolved. This slurry is crucial for achieving the signature silky texture of the scallops. Return the pot with the broth to medium heat and bring it to a gentle simmer.
Add the prepared scallops to the simmering broth and cook for 2-3 minutes until they turn opaque and begin to float to the surface. Immediately pour the cornstarch slurry into the pot while stirring continuously for 1-2 minutes until the broth thickens slightly and becomes glossy. The scallops should now have a velvety sheen.
Finish and Garnish
Remove the pot from heat and stir in the 1 tbsp sesame oil and remaining green onion greens (chopped). The sesame oil adds a nutty depth while the green onions provide a fresh contrast. Let the soup rest for 2-3 minutes to allow the flavors to meld completely.
Ladle the soup into bowls and garnish each serving with 1 tsp toasted sesame seeds. Serve immediately while the scallops maintain their perfect texture and the broth remains steaming hot. The soup should be fragrant with ginger and lemongrass, with each bite delivering tender scallops in a velvety broth.
Pro Tips For Making Chinese Scallop Soup
- Soak Scallops 30 Minutes: Dry sea scallops absorb flavor like a sponge—give them a good 30-minute soak in warm water before cooking. I used to skip this and wonder why my soup tasted flat; the hydration makes all the difference, especially if your scallops are on the tougher side.
- Bruise Ginger, Don’t Slice: Toss the ginger root into the pot whole, then smash it with the back of a knife before adding liquid. This releases more aroma without turning the soup into a ginger slurry. (Yes, even if you’re impatient like me—just don’t overdo the smashing.)
- Simmer Low After Boil: Once the soup reaches a rolling boil, drop the heat to the lowest setting that keeps tiny bubbles breaking the surface. I learned this the hard way—high heat after boiling turns scallops rubbery and scatters star anise bits everywhere.
- Toast Star Anise First: Dry-toast the star anise pods in the pot for 30 seconds before adding liquid—it deepens their flavor without bitterness. Sounds weird, but it works: the aroma jumps from subtle to actually present in the final soup. (Your future self will notice.)
Make-ahead tips for leftovers
Broth Prep Ahead
Make the fragrant ginger-lemongrass broth 24 hours ahead—it develops deeper flavor when chilled overnight. After simmering and straining, let it cool completely, then refrigerate in an airtight container.
The aromatics' oils infuse more fully, creating a richer base. Reheat gently over low heat until steaming, then add scallops fresh to avoid overcooking. 🌿
Scallop Prep Shortcut
Pat and dry scallops 1 hour ahead and store them uncovered in the fridge. This prevents moisture buildup and ensures they sear beautifully. Keep them at room temperature for 10 minutes before cooking to remove any chill. I always do this—it makes the difference between restaurant-quality and homemade. 🦪
Freezer-Friendly Components
Freeze the broth separately in 1-cup portions for quick meals. Use freezer-safe silicone molds for easy single-serving storage. When ready to cook, thaw overnight in the fridge, then proceed with fresh scallops. The broth retains its clarity and aroma perfectly. 🧊
Garnish Assembly
Toast sesame seeds and chop green onions ahead of time—store them in small containers at room temperature. This saves precious minutes when serving. I keep a jar of toasted seeds and chopped green onions in my pantry for quick garnishes on any soup. ✨
Double-Batch Strategy
For crowd-pleasing portions, double the broth recipe and freeze half. Use the fresh half immediately, then pull the frozen portion from the freezer 24 hours before serving. This ensures even thawing and maintains the perfect texture when reheated. Perfect for dinner parties! 💫
Leftovers Reinvention
Transform leftover soup into scallop dumplings by mixing broth with chopped scallops, cornstarch, and green onions. Drop spoonfuls into boiling water for 3-4 minutes until they float. Top with sesame oil and extra seeds for a fun twist. This keeps scallops from drying out! 🥟

Frequently asked questions
Can I substitute fresh scallops for dry sea scallops?
Use 1.5 lb fresh sea scallops instead, but pat them thoroughly dry and remove the side muscles first. Fresh scallops cook even faster—just reduce the simmering time to 1-2 minutes after adding them to the broth. The cornstarch slurry still works the same way to create that signature velvety texture.
Why does my broth look cloudy?
Cloudiness usually means the scallops weren't dry enough or the broth boiled too vigorously. Always pat scallops completely dry before cooking, and keep the broth at a gentle simmer—not a rolling boil. If it's already cloudy, strain it through a coffee filter for a crystal-clear finish.
Can I make this soup without lemongrass?
Yes! Replace it with 1 tsp lemongrass paste or ½ tsp lemongrass powder, but the flavor won't be as vibrant. For a similar citrusy note, add 1 tbsp lime zest or ½ tsp citronella extract (food-grade only). The ginger and star anise will still provide that warm, aromatic base.
How do I know when scallops are done?
Scallops are perfectly cooked when they turn opaque (no longer translucent) and begin to float to the surface—this takes about 2-3 minutes in simmering broth. Cut one open to check: the center should be just barely firm, not rubbery or dry. Overcooking turns them tough!
Is this soup gluten-free?
Yes, as written! Just use tamari instead of regular soy sauce for a gluten-free version. All other ingredients are naturally gluten-free. The recipe also avoids common allergens like dairy and nuts, making it safe for many dietary needs.
