Ingredients You’ll Need

These ingredients come together so nicely—sweet potatoes provide that comforting base, while the garlic, ginger, and lemongrass give the soup fresh, aromatic notes. A tip: using fresh lemongrass really makes a difference if you can find it, but you can also substitute with frozen or ground lemongrass in a pinch.

• Vegetable oil: Helps to saute the aromatics gently without burning.
• Garlic: Adds depth and a subtle pungency; fresh is best.
• Minced ginger: Brings warmth and a hint of spice, key for authentic flavor.
• Minced lemongrass: Bright, citrusy flavor that makes the soup feel truly Thai.
• Diced sweet potatoes: The star ingredient, peeled and cut into uniform pieces to cook evenly.
• Diced Bartlett pears: A surprising but delightful addition that adds natural sweetness and complexity.
• Red curry paste: Provides the spicy, savory backbone—adjust the amount based on how spicy you like it.
• Coconut milk: For luscious creaminess and that signature tropical flavor.
• Vegetable stock: Use a good-quality stock to deepen the soup’s flavor.
• Fish sauce: Adds umami and saltiness; can be substituted or omitted for a vegan version.
• Kosher salt and black pepper: Essential for seasoning and balancing all the flavors.

Variations

I love how flexible this Thai Coconut Sweet Potato Soup Recipe is—you can play around with the sweetness, spice level, or even protein additions to make it your own. I often tweak it depending on what’s in the fridge or the season.

• Add Protein: I’ve added chickpeas or shredded chicken for a heartier meal that keeps everyone full.
• Make it Vegan: Simply skip the fish sauce or replace it with a splash of soy sauce or tamari for that umami kick.
• Spice it Up: Add more red curry paste or a dash of chili flakes if you want extra heat; I learned this after wanting more heat without overpowering the soup.
• Seasonal Produce: Swap pears for apples or use pumpkin instead of sweet potatoes for a fall twist.

How to Make Thai Coconut Sweet Potato Soup Recipe

Step 1: Saute the Aromatics

First, heat your pot over medium heat and add the vegetable oil. When it’s hot, toss in the garlic, ginger, and minced lemongrass. Stir these for about 30 seconds—just until fragrant but definitely avoid browning them, or they’ll taste bitter. This is where the magic begins, so keep an eye on your pan!

Step 2: Cook the Sweet Potatoes and Pears

Next, add the diced sweet potatoes and pears to the pot and crank the heat up to medium-high. Sauté them for about 5 minutes, letting their flavors mingle with the aromatics. You’ll notice the kitchen filling with a wonderful, warm scent—the kind that makes you excited for dinner.

Step 3: Build the Soup Base

Now, stir in the red curry paste, coconut milk, and half a cup of the vegetable stock. Mix everything well so the curry paste dissolves completely. Bring the mixture to a boil briefly, then lower to a gentle simmer. Cover the pot and let it cook until those sweet potatoes are tender—about 20 minutes. This slow simmer is what softens the potatoes perfectly and allows all those flavors to marry.

Step 4: Puree the Soup for Silky Smoothness

Once the sweet potatoes are soft, blend the soup with the remaining vegetable stock and fish sauce until silky smooth. I recommend doing this in batches if your blender isn’t large. If the soup’s too thick for your liking, add more stock a splash at a time—blend in 30-second bursts until you hit your perfect consistency.

Step 5: Season to Taste and Serve

Finally, give the soup a taste and season it with salt and pepper to your liking. Sometimes I like a little extra fish sauce for depth, but be cautious as it’s quite salty. Serve this soup hot and get ready for compliments!

How to Serve Thai Coconut Sweet Potato Soup Recipe

Garnishes

I’m a big fan of topping this soup with fresh cilantro or Thai basil because the herbal notes brighten the rich coconut base. A squeeze of lime juice is a game changer—it adds just the right amount of acidity. Some toasted pumpkin seeds or chopped peanuts add a satisfying crunch if you’re feeling fancy.

Side Dishes

My family loves pairing this soup with simple jasmine rice or a side of steamed bok choy for balance. Sometimes I serve it with crispy spring rolls or fresh summer rolls if I want a full Thai-inspired meal that feels light but filling.

Creative Ways to Present

For a dinner party, I’ve served the soup in small coconut shell bowls to amp up the tropical vibe—it’s a great conversation starter! You can also swirl in a little coconut cream on top for a pretty, marbled effect and garnish with edible flowers if you want to impress your guests.

Make Ahead and Storage

Storing Leftovers

I’ve found the soup keeps well in an airtight container in the fridge for up to 4 days. Re-stir before serving as it tends to thicken overnight. The flavors actually deepen, so leftovers can be even better than fresh!

Freezing

I freeze this Thai Coconut Sweet Potato Soup Recipe regularly for busy weeks. Just make sure it’s cooled completely and use freezer-safe containers. When you thaw it, the texture holds up beautifully—just add a little water or stock when reheating if it’s too thick.

Reheating

Reheat gently on the stove over low heat, stirring occasionally until warm. I avoid microwaving because it can make the soup separate a bit, but if you do, stir well halfway through heating to keep it smooth and creamy.
