Hi everyone, Lin here! If you’ve ever traveled to Xiamen in Fujian province, you’ve likely encountered their famous street food: Sha Cha Mian (Shacha Noodles). When I visited Xiamen, I tried several highly-rated local spots. While the authentic street versions have a very distinct, slightly funky flavor profile that locals adore, I found it a bit too overpowering for my everyday palate.
When I got back home, I decided to grab a jar of Shacha sauce and experiment in my own kitchen. I wanted to unlock a simpler, homestyle version that captured the rich, savory essence of the broth without the overly complex, heavy notes. Although this might not be a strictly traditional Xiamen street recipe, it turned out unbelievably delicious—far better suited to my family’s taste buds! Today, I’m sharing this comforting, 30-minute seafood noodle soup that is perfect for a quick weeknight dinner.
What Is Seafood Shacha Noodles (Sha Cha Mian)?
Shacha Noodles is a signature noodle soup from Fujian province, China, particularly famous in Xiamen. The soul of the dish is the broth, which is heavily flavored with Shacha sauce (a savory, slightly spicy, and sweet umami paste made from soybean oil, garlic, shallots, chilis, brill fish, and dried shrimp). A bowl typically features a rich, opaque soup loaded with various toppings like fresh seafood, pork liver, fish balls, and tofu puffs. My homestyle version streamlines the ingredients, focusing on a clean, seafood-forward broth enriched with a touch of peanut and sesame paste.
Ingredients
For the Noodle Soup Base:
- Noodles: 1 bunch (about 200g / 7 oz) of fresh wheat noodles or alkaline noodles. If you aren’t sure which noodles to pick, understanding the Types of Chinese Noodles Explained can help you choose the best texture for soups.
- Stock or Water: 2 bowls (about 480ml / 2 cups) of chicken stock, seafood stock, or simply water.
- Lettuce: 3-4 leaves of fresh romaine or iceberg lettuce, for a crisp bite.
For the Flavorings & Aromatics:
- Cooking Oil: 1 tbsp (15ml) neutral oil (like canola or avocado).
- Minced Garlic: 1 tbsp (about 3 cloves), finely minced.
- Shacha Sauce (Sa Cha Sauce): 3 tbsp. This is one of the most Essential Chinese Sauces you can keep in your pantry for instant umami.
- Peanut Paste & Sesame Paste: 2 tbsp total (I use a 50/50 mix). Using authentic Chinese Sesame Paste provides a deep, roasted nutty flavor that thickens the broth.
- Chili Oil: 1 tbsp. You can use store-bought, or make your own Chinese Chili Oil for a fresher kick.
- Milk Powder: 1 tbsp. (A chef’s secret to adding a creamy, milky richness without diluting the flavor).
- Light Soy Sauce: 1 tbsp (15ml) to taste. A high-quality Light Soy Sauce is crucial for balancing the saltiness.
- Chicken Bouillon & Salt: To taste (about 1/2 tsp each).
For the Seafood:
- Fresh Shrimp: 250g (about 0.5 lb), head-on and shell-on.
- Assorted Seafood: A handful of fresh clams, squid rings, or fish balls (adjust to your preference).
Equipment Needed
- Wok or Deep Sauté Pan: For frying the shrimp heads and building the broth.
- Medium Pot: For boiling the noodles and blanching the vegetables.
- Spider Skimmer or Slotted Spoon: For removing the shrimp heads and transferring noodles.
- Instant-Read Thermometer: Optional, but highly recommended to ensure seafood reaches a safe internal temperature.
Prep & Mise en Place
- Prepare the Shrimp: Thoroughly wash the shrimp. Use kitchen shears to snip off the shrimp heads. Do not throw the heads away! Set them aside in a small bowl. Peel and devein the shrimp bodies.
- Clean the Clams: If using fresh clams, ensure they have been soaked in salted water to purge any sand, then scrub the shells clean.
- Mix the Pastes: In a small bowl, whisk together the Shacha sauce, peanut/sesame paste, and chili oil so they dissolve easier in the wok.
Cooking Process
Step 1: Extract the Shrimp Oil (3-5 minutes)
Heat 1 tbsp of oil in your wok over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Add the reserved shrimp heads. Use your spatula to press down on the heads gently as you stir-fry. Cook for 3-5 minutes until the oil turns a bright, beautiful orange.
💡 The Science of Flavor: Frying the shrimp heads in oil extracts astaxanthin (the pigment that turns shrimp pink) and fat-soluble flavor compounds. This step creates an incredibly rich, aromatic seafood base oil that plain water or stock simply cannot replicate.
Step 2: Build the Broth (5-7 minutes)
Lower the heat to medium-low to prevent burning. Add the mixed Shacha, sesame/peanut paste, and chili oil to the wok. Stir-fry for 1 minute until fragrant. Pour in the 2 bowls of stock or water. Add the 1 tbsp of milk powder. Bring the mixture to a gentle boil over medium-high heat. Season with light soy sauce, chicken bouillon, and salt to taste. Let it simmer for 3 minutes to allow the flavors to meld.
Step 3: Cook the Seafood (3-5 minutes)
Using a slotted spoon, scoop out and discard the cooked shrimp heads from the broth. Drop your cleaned shrimp bodies, clams, and fish balls into the boiling Shacha broth. Cook for 3-5 minutes. The clams should open up, and the shrimp should curl and turn pink.
(Food Safety Note: The FDA recommends cooking seafood to an internal temperature of 145°F / 63°C). Once cooked, turn off the heat.
Step 4: Prepare the Noodles (4-5 minutes)
While the seafood is cooking, bring a separate pot of water to a rolling boil. Add your noodles and cook according to the package directions (usually 3-4 minutes for fresh noodles). In the last 30 seconds of boiling, toss in the lettuce leaves to blanch them quickly.
Step 5: Assemble and Serve
Drain the noodles and lettuce, and place them into large serving bowls. Ladle the hot Shacha broth and the cooked seafood generously over the noodles. Serve immediately!
Why This Recipe Works
- Shrimp Head Oil: Sautéing the shrimp heads first lays down an umami-packed foundation that elevates the entire dish from a simple noodle soup to a restaurant-quality meal.
- The Paste Trio: Combining Shacha sauce with peanut and sesame pastes creates a complex, nutty, and savory flavor profile that thickens the broth slightly, helping it cling to the noodles.
- Milk Powder Trick: Adding a spoonful of milk powder mimics the traditional addition of evaporated milk, providing a creamy mouthfeel and rounding out the sharp spices.
Common Mistakes When Making Seafood Shacha Noodles
- Mistake: Boiling the paste mixture over high heat for too long.
- Why it happens: Trying to rush the cooking process.
- Solution: Nut pastes and Shacha sauce contain oils and solids that can easily separate or scorch. Simmer the broth gently on medium heat.
- Mistake: Chewy, overcooked seafood.
- Why it happens: Leaving the seafood in the broth while dealing with the noodles.
- Solution: Always prep your noodle boiling water simultaneously. As soon as the seafood is opaque and cooked through, remove the wok from the heat.
Frequently Asked Questions
Can I use evaporated milk instead of milk powder?
Yes! You can substitute the milk powder and a portion of the water with about 1/4 cup of evaporated milk added at the very end of cooking.
Can I make the broth ahead of time?
Absolutely. You can make the broth (without the seafood) up to 3 days in advance. Store it in the fridge, bring it to a simmer, and cook your fresh seafood right before serving.
Is it possible to make this vegetarian?
To make a vegetarian version, omit the shrimp and use vegetable stock. You can load it up with tofu, mushrooms, and greens.
How to Serve
This rich noodle soup is a meal in itself. However, if you are hosting a larger dinner, you can serve it alongside an Easy Shrimp and Tofu Stir-Fry for a complete seafood feast. If you love seafood, you might also want to check out my hearty Scallion Seafood Pot for another weekend project. To add a punchy side dish, whip up a quick cucumber salad tossed with a basic Garlic Sauce for Stir Fry.
Storage & Reheat
- Storage: It is best to store the broth/seafood and the noodles in separate airtight containers in the refrigerator for up to 2 days. Storing them together will cause the noodles to bloat and absorb all the soup.
- Reheat: Gently warm the broth and seafood in a saucepan over medium heat until it reaches a simmer. Re-warm the noodles by quickly dunking them in hot water or microwaving them briefly before pouring the hot broth over them. Do not freeze this soup, as the seafood texture will degrade.
Allergen Notice
- Shellfish: Contains shrimp and clams.
- Soy: Contains soy sauce and Shacha sauce (soybean oil).
- Peanuts/Sesame: Contains peanut paste and sesame paste.
- Dairy: Contains milk powder.
- Gluten: Contains wheat noodles and soy sauce.
