Step‑by‑Step Instructions for Spicy Lemongrass Coconut Noodle Soup
Step 1: Build the Broth
In a large pot, heat up 2 tablespoons of neutral oil over medium heat. Once the oil is shimmering, add a halved small red onion, and char it until browned, about 3-4 minutes. Stir in minced garlic and chopped fresh lemongrass, cooking until fragrant, around 1-2 minutes. Add 2 tablespoons of chili garlic sauce, stir for a minute, then pour in 4 cups of water along with a vegetable bouillon cube. Simmer the broth for 15 minutes while you prep the next steps.
Step 2: Season the Broth
After 15 minutes of simmering, taste the broth and add about 2-3 tablespoons of vegan fish sauce, a pinch of salt, and 1 tablespoon of brown sugar to balance the flavors. Stir well and keep the broth warm over low heat. Finally, add one can of full-fat coconut milk, letting it gently heat through without boiling, while you prepare the tofu and noodles.
Step 3: Cook the Tofu
While the broth simmers, press and slice 14 ounces of extra firm tofu into cubes. Heat 2 tablespoons of neutral oil in a non-stick skillet over medium-high heat. Once hot, add the tofu cubes and fry until golden brown and crispy on all sides, approximately 5-7 minutes. In the last minute of cooking, drizzle in 2 tablespoons of soy sauce, 1 tablespoon of sake, and 1 teaspoon of sugar, tossing to coat the tofu evenly.
Step 4: Prepare the Noodles
In another pot, bring water to a boil and then remove it from the heat. Add 4 ounces of dry vermicelli noodles to the hot water, letting them soak for about 4-5 minutes or until softened. Drain the noodles and set them aside, ensuring they don’t clump together, ready for assembly into your Spicy Lemongrass Coconut Noodle Soup.
Step 5: Blanch the Vegetables
With the broth still warm, add chopped bok choy or your choice of greens into the pot. Cook for 1-2 minutes until the greens are tender yet still bright and crisp. This short cooking time helps retain their nutrition and vibrant color, enhancing the overall aesthetic and flavor of your soup.
Step 6: Assemble the Soup
In serving bowls, divide the soaked vermicelli noodles evenly. Ladle the hot, fragrant broth over the noodles, ensuring everyone gets a good mix of the rich coconut sauce and fresh greens. Top each bowl with crispy tofu cubes for added protein, then garnish generously with fresh cilantro, a squeeze of lime juice, and a sprinkle of fried shallots for that irresistible crunch. Serve hot and savor the cozy delight of your Spicy Lemongrass Coconut Noodle Soup!

How to Store and Freeze Spicy Lemongrass Coconut Noodle Soup
Fridge: Store any leftovers of your Spicy Lemongrass Coconut Noodle Soup in an airtight container for up to 3 days. Reheat gently on the stove, adding a splash of broth or water to refresh the flavors.
Freezer: If you’d like to keep it longer, freeze the soup without the noodles and vegetables in a suitable container for up to 2 months. Thaw overnight in the fridge before reheating.
Noodles: If possible, keep the vermicelli noodles separate until serving, as they absorb the broth and may become mushy. Cook fresh noodles when you’re ready to enjoy the soup.
Reheating: When reheating, always do so slowly over low heat to prevent curdling the coconut milk. Stir frequently and enjoy the aromatic flavors once more!

Spicy Lemongrass Coconut Noodle Soup Recipe FAQs
What type of fresh lemongrass should I use for this recipe?
For the best flavor, I recommend using fresh lemongrass stalks. Look for firm, plump stalks without any dark spots. If fresh isn’t available, you can substitute it with frozen minced lemongrass or lemongrass paste, which works well in a pinch.
How should I store leftovers of the Spicy Lemongrass Coconut Noodle Soup?
Absolutely! Transfer any leftovers to an airtight container and store them in the fridge for up to 3 days. When you’re ready to enjoy, reheat gently on the stove and add a splash of broth or water to bring back the lovely flavors.
Can I freeze this soup for later use?
Yes, you can! However, it’s best to freeze the broth without the noodles or vegetables. Store the cooled broth in a freezer-safe container for up to 2 months. Thaw it overnight in the fridge before reheating. When you’re ready to serve, cook fresh noodles and add them to the reheated broth.
What should I do if the soup turns out too spicy for my taste?
If you find the soup too spicy, don’t worry! You can temper the heat by adding more coconut milk or vegetable stock to dilute it slightly. This not only reduces the spice levels but also enhances the creamy texture. Another option is to serve it with a dollop of yogurt or sour cream for balancing heat.
Is this soup suitable for people with soy allergies?
If you or someone you’re serving has a soy allergy, you can still enjoy this delicious Spicy Lemongrass Coconut Noodle Soup! Simply substitute the soy sauce used in the tofu with coconut aminos or tamari, which is a gluten-free soy sauce alternative. Just keep an eye on any additional ingredients you choose to use for hidden soy content.
How do I know when the bok choy is cooked perfectly?
This is a great question! Add the chopped bok choy to the broth and cook it for about 1-2 minutes until it’s tender yet still bright green. You want to maintain a little crunch for texture. Overcooking can make it mushy, so keep an eye on it!
