Ingredients
- 3 large sweet potatoes peeled and cut into wedges (~600 g)
- 2 tbsp (30 ml) olive oil, plus extra for roasting
- 1 medium onion diced (~150 g)
- 2 cloves garlic minced
- 1 tsp dried thyme, plus extra sprigs for garnish
- 1 tsp dried rosemary
- 1 tsp dried basil
- 4 cups (1 liter) vegetable broth
- 1 cup (240 ml) coconut milk or heavy cream
- Salt and pepper to taste
Instructions
- Step 1: Preheat your oven to 400°F (200°C). Arrange the sweet potato wedges on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast for 25-30 minutes until tender and caramelized at the edges. Set aside a few wedges for garnish if desired.
- Step 2: In a large pot, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté for about 5 minutes until softened.
- Step 3: Add the minced garlic, dried thyme, rosemary, and basil to the pot. Cook for 1-2 minutes until fragrant.
- Step 4: Add the roasted sweet potatoes to the pot along with the vegetable broth. Stir to combine and bring to a boil.
- Step 5: Reduce the heat and simmer for 10-15 minutes to let the flavors meld.
- Step 6: Use an immersion blender to blend the soup until smooth and creamy. For a finer texture, blend in batches using a regular blender.
- Step 7: Stir in the coconut milk or heavy cream and heat through for 5 more minutes. Season with salt and pepper to taste.
- Step 8: Ladle the soup into bowls and garnish with reserved roasted sweet potato wedges and a sprig of fresh thyme. Serve warm and enjoy!
Tips & Variations

- Swap vegetable broth for chicken broth if not vegetarian; it adds a savory depth.
- Use fresh herbs if available, adding them at the end of cooking to preserve brightness.

FAQs
Can I use regular potatoes instead of sweet potatoes?
Yes, but the flavor and natural sweetness will be different. Regular potatoes will create a more neutral taste, so consider adding a touch of honey or sugar to retain some sweetness.
Is this soup suitable for vegans?
It can be made vegan by using coconut milk and vegetable broth. Avoid heavy cream and choose plant-based alternatives to keep it fully vegan.
