Ingredients

Scale

Vegetables

  • 3 large sweet potatoes, peeled and cut into wedges (~600 g)
  • 1 medium onion, diced (~150 g)
  • 2 cloves garlic, minced

Herbs & Seasonings

  • 1 tsp dried thyme (plus extra sprigs for garnish)
  • 1 tsp dried rosemary
  • 1 tsp dried basil
  • Salt and pepper to taste

Liquids & Fats

  • 2 tbsp (30 ml) olive oil (plus extra for roasting)
  • 4 cups (1 liter) vegetable broth
  • 1 cup (240 ml) coconut milk or heavy cream

Instructions

  1. Roast the Sweet Potatoes: Preheat the 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.
  2. Sauté the Aromatics: 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. Stir in the minced garlic, dried thyme, rosemary, and basil, cooking for another 1-2 minutes until fragrant.
  3. Combine and Simmer: Add the roasted sweet potatoes to the pot along with the vegetable broth. Stir well to combine and bring the mixture to a boil. Reduce the heat and simmer for 10-15 minutes to meld the flavors.
  4. Blend the Soup: Use an immersion blender to puree the soup until smooth and creamy. For an extra fine texture, transfer in batches to a regular blender. Stir in the coconut milk or heavy cream and heat through for an additional 5 minutes. Season with salt and pepper to taste.
  5. Serve: Ladle the soup into bowls and garnish with the reserved roasted sweet potato wedges and a sprig of fresh thyme. Serve warm with crusty or garlic bread, if desired.

Notes

  • Roasting the sweet potatoes caramelizes their natural sugars, enhancing the soup’s sweetness and depth.
  • Blend thoroughly to achieve a silky, velvety texture.
  • Adjust salt and pepper only after blending and adding cream to ensure balanced flavor.
  • Add extra veggies like carrots or parsnips for more complexity.
  • For a spicy kick, sprinkle in red pepper flakes.
  • Use coconut milk for a vegan, dairy-free option or heavy cream for richer flavor.
  • Garnish with fresh herbs such as thyme or rosemary for brightness.
  • Store leftovers in an airtight container refrigerated up to 4 days, or freeze for up to 3 months.
  • Reheat gently, adding water or broth if soup becomes too thick.
