- One 2-inch piece ginger, peeled and thickly sliced
- 1 medium yellow onion, peeled and quartered
- 3 cloves garlic, peeled
- 2 tablespoons fish sauce

Preparing the Ingredients
Properly preparing the ingredients is essential for maximizing the flavor of the soup.
For the crab:
- Rinse the crab under cold water to clean.
- Pick through the meat gently to remove any stray shells or cartilage.
- Try not to break up the crab too much so it stays in nice chunks.
For the asparagus:
- Rinse the asparagus and trim off the tough, woody ends.
- The spears should snap easily when bent.
- Cut the spears on the diagonal into 2-inch segments.
For the aromatics:
- Peel the ginger and garlic.
- Cut the lemongrass stalks and bruise them.
- Quarter the onion with the root end intact to help hold shape during cooking.
For the tofu:
- Drain the excess water by wrapping in paper towels.
- Cut the block into even 1/2-inch cubes.
Making the Broth For Soup
The broth is simple to prepare but essential for infusing this soup with its signature Vietnamese flavor.
Here are a few tips:
- Char the aromatics – Char the ginger, onion, and garlic before adding to the pot to enhance flavor.
- Simmer the broth – Let it simmer for at least 30 minutes to extract all the flavors.
- Strain before using – Straining removes sediment so the broth stays clean.
Step-by-Step Instructions
- In a large pot, bring the water to a boil over high heat.
- Add the lemongrass, charred ginger, onion, and garlic. Reduce heat to medium-low and simmer for 30 minutes.
- Strain the broth through a fine mesh strainer into a clean pot. Discard solids.
- Add the fish sauce, sugar, and black pepper. Taste and adjust seasoning as needed.

- Bring the broth to a gentle simmer over medium heat.

- Turn off heat and add the green onions and cilantro.

How to make Súp Măng Cua (Vietnamese Crab and Asparagus Soup)
Notes
- You can adjust the amount of fish sauce to your preference.
- For a richer flavor, brown the crab meat in a pan with a little oil before adding it to the soup.
- If you don't have quail eggs, you can use regular chicken eggs, boiled and halved.
- Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently over low heat.
- Substitute dried white fungus (soaked and sliced) for asparagus for a different textural experience.
Ingredients
- • 6-8 cups chicken or vegetable broth
- • 1-2 cups fresh, canned, or imitation crab meat
- • 1 bunch (around 10 stalks) white or green asparagus
- • 1 can (around 10-12) quail eggs
- • 2-3 eggs (whites or whole, optional)
- • 2-3 tablespoons cornstarch
- • 1-2 tablespoons fish sauce
- • 1 shallot, thinly sliced (for garnish)
- • Chopped cilantro (for garnish)
- • White pepper (to taste)
- • Chicken bouillon (to taste)
- • Dried white fungus (soaked and sliced, substitute for asparagus)
Instructions
- Prepare the Broth: Bring the chicken or vegetable broth to a boil in a large pot.
- Prepare the Asparagus: Wash and trim the asparagus. If using white asparagus, peel the bottom third of the stalks. Cut the asparagus into bite-sized pieces.
- Prepare the Crab Meat: If using fresh crab, remove the meat from the shell and claws. Flake the crab meat into bite-sized pieces.
- If using canned crab meat, drain it well.
- Simmer the Soup: Add the asparagus to the boiling broth and simmer for 5-7 minutes, or until tender-crisp.
- Add Crab and Seasonings: Add the crab meat, quail eggs, and fish sauce to the pot. Season with white pepper (to taste) and chicken bouillon (optional, to taste). Simmer for another 2-3 minutes, just until the crab meat is heated through.
- Thicken the Soup (Optional): In a small bowl, whisk together cornstarch and a little cold water to make a slurry. Slowly drizzle the cornstarch slurry into the soup while stirring constantly. Bring the soup back to a simmer and cook for 1-2 minutes, or until the soup thickens to your desired consistency.
- Egg Swirls (Optional): If using eggs, lightly beat the eggs (whites or whole) in a separate bowl. Slowly pour the beaten eggs into the simmering soup while swirling the pot to create thin egg ribbons.
