Step‑by‑Step Instructions for Spicy Lemongrass Coconut Noodle Soup
Step 1: Build the Broth
In a medium pot, char the halved red onion over medium-high heat for about 5-7 minutes until browned and aromatic. Add 2 tablespoons of neutral oil, then sauté minced garlic and chopped lemongrass for another 2 minutes until fragrant. Stir in 2 tablespoons of chili garlic sauce, cooking briefly before pouring in 4 cups of water and adding a vegetable bouillon cube. Simmer for 15 minutes.
Step 2: Season the Broth
After simmering, season your broth by stirring in 2 tablespoons of vegan fish sauce, salt, and brown sugar to balance the flavors. Once the seasoning is to your taste, gently stir in a can of coconut milk for creaminess. Let the broth simmer on low heat while you prepare the other components of your Spicy Lemongrass Coconut Noodle Soup.
Step 3: Cook the Tofu
Drain and press your firm tofu for about 15 minutes, then slice it into rectangular pieces. In a skillet, heat 2 tablespoons of oil over medium heat, then add the sliced tofu. Cook for 5-7 minutes, flipping until both sides are golden brown. Add 2 tablespoons of soy sauce, 1 tablespoon of sake, and 1 teaspoon of sugar, cooking until the tofu becomes caramelized, about 3 minutes.
Step 4: Prepare the Noodles
While your tofu is cooking, soak 200 grams of vermicelli noodles in a bowl of hot water for about 10 minutes, or until they become chewy. Once softened, drain the noodles and set them aside, keeping them warm. This step ensures you have the delightful chewy texture that complements the broth perfectly.
Step 5: Blanch the Vegetables
With your broth still simmering, add the chopped bok choy or your choice of greens to the pot. Blanch the greens for just 1-2 minutes until they are bright and tender but still crunchy. This quick cooking method preserves their vibrant color and nutrients, enhancing your Spicy Lemongrass Coconut Noodle Soup’s freshness.
Step 6: Assemble the Soup
To serve, distribute the prepared vermicelli noodles equally into bowls. Using a ladle, pour the hot broth over the noodles, ensuring a generous amount of the aromatic broth. Top each bowl with the blanched bok choy and golden tofu for a beautiful presentation, making your Spicy Lemongrass Coconut Noodle Soup not just nourishing but visually appealing as well.
Step 7: Garnish and Serve
Finish your soup by garnishing each bowl with freshly chopped cilantro, a squeeze of lime juice, and crispy fried shallots for added texture and flavor. Serve hot for the best experience, inviting everyone to enjoy the comforting warmth and vibrant flavors of this delightful Spicy Lemongrass Coconut Noodle Soup!

Make Ahead Options
These Spicy Lemongrass Coconut Noodle Soup components are perfect for meal prep enthusiasts! You can prepare the broth up to 3 days in advance; simply store it in an airtight container in the refrigerator. Cook the tofu and store it separately for the best texture; this can also be done up to 3 days ahead. The vermicelli noodles can be soaked in hot water up to 2 hours prior to serving, ensuring they’re chewy and ready to incorporate. When you’re ready to serve, just reheat the broth and add the noodles and tofu. This allows you to enjoy a comforting, homemade meal with minimal effort on busy weeknights!
Spicy Lemongrass Coconut Noodle Soup Variations

How to Store and Freeze Spicy Lemongrass Coconut Noodle Soup
Fridge: Store any leftovers in an airtight container for up to 3 days. To maintain freshness, keep the broth and noodles separate until ready to serve.

Spicy Lemongrass Coconut Noodle Soup Recipe FAQs
What should I look for when selecting lemongrass?
Absolutely! When selecting lemongrass, look for stalks that are firm and plump with a vibrant green color. Avoid any that have dark spots or are dried out, as this indicates age. The more fresh the lemongrass, the more aromatic and flavorful it will be in your soup.
How should I store leftovers of the Spicy Lemongrass Coconut Noodle Soup?
To store leftovers, place them in an airtight container in the fridge for up to 3 days. For best results, keep the broth separate from the noodles and vegetables until you’re ready to reheat, as this prevents the noodles from getting soggy.
Can I freeze Spicy Lemongrass Coconut Noodle Soup?
Yes, you can freeze the broth! Pour the cooled broth into a freezer-safe container, leaving some space for expansion, and freeze for up to 2 months. Ideally, avoid freezing cooked noodles and vegetables, as they lose their texture when thawed.
What if my broth is too salty or sweet?
If your broth tastes too salty or sweet, you can adjust it! Add a splash of water to dilute the flavor and taste as you go. For a sweet counterbalance, try incorporating a bit more lime juice or adding fresh herbs to bring back the flavor balance.
Is this soup suitable for people with food allergies?
Always check the individual ingredients for allergens. This soup is naturally vegan and gluten-free (if using gluten-free noodles), making it a good option for many dietary restrictions. However, for those with soy allergies, substitute soy sauce with coconut aminos. Always check with your guests to ensure their dietary needs are met.
How can I enhance the creaminess of my soup?
For a creamier soup, you can add more coconut milk or a splash of almond milk while simmering the broth. Additionally, blending a portion of the soup can give it a luxurious creamy texture without losing the delightful noodle experience!
