Now that your Spicy Lemongrass Coconut Noodle Soup ingredients are ready, let’s move on to the instructions to bring this cozy bowl to life!
Step‑by‑Step Instructions for Spicy Lemongrass Coconut Noodle Soup
Step 1: Build the Broth
Start by halving the red onion and charring it cut-side down in a large pot over medium-high heat for about 3-4 minutes until softened. Add a tablespoon of neutral oil, then fold in minced garlic and finely chopped fresh lemongrass, sautéing for another 2-3 minutes until fragrant. Stir in 2 tablespoons of chili garlic sauce to incorporate the heat for your Spicy Lemongrass Coconut Noodle Soup.
Step 2: Simmer Broth
Pour in 4 cups of water along with a vegetable bouillon cube, then bring the mixture to a gentle simmer over medium heat for about 15 minutes; you’ll notice the tantalizing aromas filling your kitchen. Once simmered, season the broth with 2 tablespoons of vegan fish sauce, a teaspoon of salt, and a tablespoon of brown sugar before pouring in 1 can of creamy coconut milk, stirring well to combine.
Step 3: Cook Tofu
While the broth is simmering, drain and press the extra firm tofu to eliminate excess moisture. Cut the tofu into bite-sized cubes and heat a skillet over medium-high heat, adding a splash of oil. Fry the tofu for about 6-8 minutes, turning occasionally until golden and crispy. Toss it with 2 tablespoons of soy sauce, a splash of sake, and a teaspoon of brown sugar, allowing the flavors to meld perfectly.
Step 4: Prepare Noodles
For the dry vermicelli noodles, place them in a bowl and cover with hot water, allowing them to soak for about 5-6 minutes until tender. Drain well and give them a gentle stir to prevent sticking. These noodles will provide the perfect chewy base for your Spicy Lemongrass Coconut Noodle Soup.
Step 5: Blanch Vegetables
Once the broth has simmered, add chopped bok choy or your choice of greens directly into the pot. Cook for about 2-3 minutes until the greens are tender-crisp, infusing the broth with their vibrant flavor and nutrients. This step adds both nutrition and color to your Spicy Lemongrass Coconut Noodle Soup.
Step 6: Assemble Soup
To serve, divide the cooked vermicelli noodles among bowls and ladle the hot, aromatic broth over them. Top each bowl with the blanched bok choy, crispy tofu, and sprinkle with fresh cilantro and a drizzle of lime juice. Finally, enhance the texture by adding a generous sprinkle of fried shallots on top, creating the ultimate comforting finish to your Spicy Lemongrass Coconut Noodle Soup.
