How to Make Thai Coconut Sweet Potato Soup

Step 1: Prep Your Ingredients

Peel and dice the sweet potatoes into even chunks to ensure they cook uniformly. Mince the garlic and ginger, and bruise the lemongrass stalk by gently smashing it with the back of a knife to release its fragrant oils.

Step 2: Sauté Aromatics

In a large pot, heat a bit of oil over medium heat, then add garlic, ginger, and red curry paste. Cook for 2-3 minutes until fragrant, allowing the spices to bloom, which builds the foundation of flavor for the soup.

Step 3: Add Sweet Potatoes and Broth

Stir in the diced sweet potatoes, lemongrass stalk, kaffir lime leaves, and vegetable broth. Bring everything to a gentle boil, then lower the heat and simmer until the sweet potatoes are tender—roughly 15-20 minutes.

Step 4: Blend the Soup

Remove the lemongrass and lime leaves, then use an immersion blender to puree the soup until smooth and creamy. Alternatively, carefully transfer the soup to a blender in batches.

Step 5: Stir in Coconut Milk and Lime Juice

Add the coconut milk and fresh lime juice, stirring gently to combine. Heat the soup through but avoid boiling to preserve the creaminess and freshness of the flavors.

Pro Tips for Making Thai Coconut Sweet Potato Soup

• Use Fresh Ingredients: Fresh ginger, lemongrass, and lime leaves will drastically elevate the flavor compared to dried or powdered substitutes.
• Don’t Skip Simmering: Allow the sweet potatoes to fully cook to ensure a silky texture when blended.
• Adjust Consistency: Add more broth if you want a lighter soup or reduce it to thicken the texture.
• Balance Flavors Carefully: Taste as you go, especially when adding lime juice and curry paste, since each brand varies in intensity.
• Garnish Thoughtfully: Fresh herbs and a sprinkle of chili flakes or toasted nuts add exciting texture and brighten the bowl.

Freezing

This soup freezes wonderfully. Portion it out into freezer-safe containers and it will keep for up to 3 months. Thaw in the fridge overnight before reheating.

FAQs

Can I use regular potatoes instead of sweet potatoes?

While regular potatoes can work, sweet potatoes add unique sweetness and creaminess that define this recipe’s character, so they’re highly recommended.

Is this soup vegetarian or vegan?

Yes! Using vegetable broth and ensuring your curry paste is free from fish sauce makes this Thai Coconut Sweet Potato Soup completely vegan and vegetarian.

How spicy is this soup?

The heat level depends on the amount and type of curry paste you use; you can easily adjust it to be mild or spicy based on your preference.

Can I make this soup in a slow cooker?

Absolutely! Simply sauté the aromatics first, then add all ingredients to the slow cooker and cook on low for 4-6 hours until sweet potatoes are tender.

What can I use instead of lemongrass?

If you don’t have lemongrass, lemon zest and a splash of lime juice can mimic some of its citrusy brightness, though the flavor won’t be quite as authentic.
