Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 cups vegetable broth
2 stalks fresh lemongrass, chopped
1 tablespoon extra-virgin coconut oil
1 medium shallot, finely diced
1 small green chili, seeded and minced
1 piece fresh ginger, peeled and minced
3 cups shiitake mushrooms, trimmed and sliced
1 1/2 cups romanesco, cauliflower, or broccoli in bite-sized pieces
1 cup zucchini, sliced into rounds
1 cup full-fat coconut milk
1 cup tightly packed cilantro leaves
1 teaspoon tamari
2 tablespoons fresh lime juice
A handful of fresh basil leaves
Salt and pepper, to taste
4 ounces rice noodles, cooked according to package directions and rinsed in cool water
Lime wedges, for serving
Directions
Bring the vegetable broth and chopped lemongrass to a boil in a medium pot. Remove from the heat and let the lemongrass steep for about 10 minutes. Strain out the lemongrass and set the broth aside.
In a large pot, heat the coconut oil over medium heat. Add the shallot, green chili, and ginger, then sauté until softened and fragrant.
Add the shiitake mushrooms and cook until they begin to soften. If the pot seems dry, add a small splash of the reserved broth. Stir in the romanesco and zucchini, then pour in the lemongrass-infused broth. Bring everything to a gentle simmer and cook until the vegetables are just tender.
In a blender, combine the coconut milk and cilantro. Blend until completely smooth and bright green.
Pour the cilantro-coconut mixture into the soup. Add the tamari, lime juice, and basil leaves. Taste and season with salt and pepper as needed. Warm the soup gently just until steaming, taking care not to boil it too much.
Divide the cooked rice noodles among serving bowls. Ladle the hot soup over the noodles and serve with lime wedges on the side.

Variations
You can easily change up the vegetables in this soup based on what is in season or already in your kitchen. Broccoli, snow peas, carrots, bell peppers, asparagus, sweet corn, or even cubes of roasted winter squash all work well.
For extra protein, add tofu, edamame, or chickpeas. If you prefer a milder soup, reduce the chili or leave it out entirely. For more heat, add extra chili or a spoonful of chili paste when serving.
Any rice noodle can be used here, so feel free to swap in brown rice noodles, black rice noodles, or even wider rice sticks for a different texture. You can also finish the soup with extra basil, cilantro, sliced green onions, or toasted sesame seeds for more flavor and texture.
Storage/Reheating
This soup is best enjoyed freshly made, when the broth is at its brightest green color and freshest flavor. Leftovers can be stored in an airtight container in the refrigerator for 1 to 2 days.
For the best texture, store the noodles separately from the broth if possible. When reheating, warm the soup gently over low heat just until hot. Avoid boiling, since too much heat can dull the green color and fresh herbal flavor. Add a fresh squeeze of lime before serving to wake the flavors back up.
FAQs
Can I make this soup ahead of time?
Yes, but it is at its best when freshly made. If preparing ahead, store the broth and noodles separately and combine them when serving.
Is this soup spicy?
It has a mild to moderate kick from the green chili. You can easily adjust the spice level by using less chili or omitting it.
What kind of noodles work best?
Rice noodles are ideal for this soup. Black rice noodles, brown rice noodles, or standard rice noodles all work well.
Can I use other vegetables?
Absolutely. This recipe is very flexible, and vegetables like broccoli, snow peas, carrots, bell peppers, asparagus, and corn are all great choices.
Can I add protein to this recipe?
Yes. Tofu is an excellent addition, and edamame or chickpeas can also make the soup more filling.
Why do I steep the lemongrass instead of blending it?
Steeping gives the broth plenty of lemongrass flavor without leaving behind the tough, fibrous texture that lemongrass can have when blended.
Can I freeze this soup?
It is not the best candidate for freezing because the herbs and coconut mixture can lose their fresh flavor and bright color after thawing.
How do I keep the broth bright green?
Heat the soup gently after adding the blended cilantro and coconut milk. Avoid boiling it, which can make the herbs lose their vivid color.
Can I use light coconut milk?
You can, but the broth will be less rich and creamy. Full-fat coconut milk gives the soup its best texture and flavor.
What should I serve with this soup?
It works well on its own as a light main dish, but you can also serve it with spring rolls, a crisp cucumber salad, or extra lime and herbs on the side.
