Vegan Thai Lemongrass Coconut Curry Soup — Do This Next

Step 1: Sauté Aromatics
In a large pot or Dutch oven, heat the olive oil over medium heat. Once hot, add the finely chopped lemongrass, chopped onion, grated ginger, and minced garlic. Sauté for about 3-5 minutes, or until the onions become translucent and fragrant.
Step 2: Add Broth and Curry Paste
Pour in the vegetable broth (or water) and stir in the Thai red curry paste. Bring the mixture to a gentle simmer, allowing the flavors to meld together beautifully.
Step 3: Add Spiralized Vegetables
Toss in the spiralized sweet potato, zucchini, and celery root. Stir well to combine and let the soup simmer for an additional 10-15 minutes, or until the vegetables are tender.
Step 4: Stir in Coconut Milk
Once the vegetables are cooked to your liking, pour in the full-fat coconut milk and stir until well combined. Allow the soup to simmer for another 5 minutes, letting the creamy goodness infuse the broth.
Step 5: Season and Serve
Add the lime juice and season with salt and pepper to taste. Remove the pot from heat and stir in the torn basil. Serve hot with extra lime wedges and a sprinkle of fresh cilantro if desired.
