Ingredients List
Crafting the best sweet potato soup starts with fresh, vibrant ingredients. Here’s what you’ll need:
- 2 large sweet potatoes (about 600 grams), peeled and diced
- 1 can (400 ml) full-fat coconut milk, for creaminess and tropical aroma
- 1 medium yellow onion, finely chopped, to build a savory base
- 2 cloves of garlic, minced, adding depth and warmth
- 1-inch piece of fresh ginger, grated, for a subtle zing
- 3 cups vegetable broth or water, depending on your preference
- 1 tablespoon olive oil or coconut oil, for sautéing
- Salt and freshly ground black pepper, to taste
- Optional garnishes: fresh cilantro, toasted pumpkin seeds, or a squeeze of lime
Substitution ideas:
- Use low-fat coconut milk if you prefer a lighter soup.
- Swap sweet potatoes with butternut squash or carrots for seasonal twists.
- Chicken broth can be used as a substitute for vegetable broth to add extra savory richness.
Timing
Preparing this classic sweet potato soup with coconut milk takes about 40 minutes, broken down as follows:
- Preparation time: 10 minutes
- Cooking time: 30 minutes
- Total: 40 minutes
Interestingly, this is roughly 20% faster than many traditional simmer-and-blend recipes, which often take upwards of 50 minutes. This timing ensures vegetables stay tender without losing their vibrant flavor.
Step-by-Step Instructions
Step 1: Sauté the Aromatics
Heat your oil over medium heat in a large pot. Add finely chopped onions and sauté for 5 minutes, until they are translucent and fragrant. Stir in the garlic and grated ginger; cook for an additional 2 minutes. This foundational step unlocks deep, savory notes that elevate your soup.
Tip: To prevent bitterness, avoid browning the garlic, keeping the soup smooth and mellow.
Step 2: Add Sweet Potatoes and Broth
Add the diced sweet potatoes and pour in the vegetable broth or water. Bring the mixture to a boil, then reduce the heat and simmer gently for 20 minutes or until the sweet potatoes are tender. Perfect tenderness is key to a silky puree.
Tip: Cover the pot loosely to retain steam and cook evenly, while allowing some evaporation to achieve a concentrated flavor.
Step 3: Blend Until Silky Smooth
Remove the soup from heat and carefully transfer it to a blender or use an immersion blender directly in the pot. Blend until completely smooth and creamy. This step transforms chunks into a luscious texture that’s pleasing to both eyes and palate.
Tip: Blend in batches if using a standing blender, and always vent the lid slightly to avoid pressure build-up.
Step 4: Stir in Coconut Milk
Return the blended soup to the pot and gently stir in the coconut milk. Warm over low heat, but do not boil, preserving the delicate coconut aroma and silky texture. Season with salt and freshly ground pepper to taste.
Tip: Adjust the quantity of coconut milk to control the creaminess. Start with ¾ cup and add more if you want a richer bowl.
Step 5: Garnish and Serve
Ladle the soup into bowls and add your favorite garnishes, such as chopped cilantro, toasted pumpkin seeds, or a fresh lime wedge. These add contrasting textures and bright notes that balance the soup’s natural sweetness.
Tip: Serve with crusty bread for a wholesome meal or a crisp green salad for freshness.
