Ingredients

• MAKES: 4 servingsTIME: 40 minutes
• 2 tablespoons neutral oil, like grapeseed or corn
• 1 large onion, chopped
• 1 teaspoon minced garlic
• 1 tablespoon peeled and minced fresh ginger
• 1 small fresh chile, preferably Thai, stemmed, seeded, and minced (optional)
• 3 stalks lemongrass, tough outer layers removed, trimmed, and minced
• 1 tablespoon Curry Powder
• 1 cup sliced shiitake mushroom caps
• 1 quart (4 cups) vegetable stock
• 1 13-ounce can unsweetened coconut milk (or 2 cups homemade)
• 2 tablespoons soy sauce, or to taste
• Salt and freshly ground black pepper to taste
• Freshly squeezed lime juice, to taste
• 1/2 cup minced scallion, for garnish
• 1/4 cup minced fresh cilantro, for garnish

Instructions

1. Put the oil in a deep skillet or medium saucepan over medium-high heat. When hot, add the onion and cook, stirring occasionally, until it begins to brown, about 10 minutes. Lower the heat slightly and continue cooking for 5 more minutes until very tender. Add the garlic, ginger, optional chile, lemongrass, and curry powder. Cook, stirring constantly, for about 1 minute until fragrant. Add the mushrooms and cook for another minute, stirring to coat.
2. Pour in the vegetable stock and bring to a boil. Reduce the heat to maintain a steady simmer and cook for about 10 minutes to let the flavors meld. Stir in the coconut milk and cook for 5 minutes more, ensuring it does not boil. Season with soy sauce, then taste and add more soy sauce, salt, or pepper if needed. Stir in a couple of tablespoons of lime juice, taste again, and add more if you like. Serve hot, garnished with fresh scallions and cilantro.

Pro Tips

• for the Best Coconut Soup
• For the best flavor, use only the tender, pale inner part of the lemongrass stalks. Finely mincing it helps release its aromatic oils directly into the soup.
• To make this a substantial main course, add pan-fried tofu cubes, crumbled tempeh, a scoop of steamed sticky rice, or a handful of soaked mung bean noodles during the last few minutes of cooking.
• Use full-fat, canned coconut milk for the richest, creamiest texture. Light coconut milk will result in a thinner soup.
• Avoid boiling the soup after adding the coconut milk, as high heat can cause it to separate or curdle. Maintain a gentle simmer.
• Don’t skip the final squeeze of lime juice. The acidity is essential for brightening and balancing the rich, creamy flavors of the soup.

FAQ

Q: How can I add more protein to this vegetarian soup
A: To make this a more substantial and protein-rich meal, add pan-fried tofu cubes, crumbled tempeh, or edamame. For best results, add them during the last few minutes of cooking to allow them to warm through without becoming mushy.

Q: Is this Thai coconut soup recipe vegan
A: Yes, this recipe is naturally vegan as written. All ingredients, including the coconut milk, vegetable stock, and soy sauce, are plant-based. Just be sure to use a vegetable stock and curry powder that are certified vegan if you have specific dietary requirements.

Q: Can I make this soup gluten-free
A: Absolutely. The only ingredient that typically contains gluten is soy sauce. To make this recipe gluten-free, simply substitute the soy sauce with an equal amount of tamari or a certified gluten-free soy sauce alternative.

Q: What other vegetables can I add to this soup
A: This soup is a great base for more vegetables. Consider adding sliced bell peppers, broccoli florets, baby corn, or snap peas. Add heartier vegetables like carrots along with the stock, and quicker-cooking ones like bell peppers in the last 5-10 minutes of simmering.

Q: How do I store leftover coconut soup
A: Store any leftover soup in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop over low-medium heat, stirring occasionally. Avoid boiling, as it can cause the coconut milk to separate. The garnishes are best added fresh just before serving.
