Ingredients

Scale

Sweet Potatoes

  • 3 large sweet potatoes, peeled and cut into wedges (~600 g)
  • Olive oil, for roasting
  • Salt and pepper, to taste

Sautéed Aromatics

  • 2 tbsp (30 ml) olive oil
  • 1 medium onion, diced (~150 g)
  • 2 cloves garlic, minced
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 1 tsp dried basil

Soup Base

  • 4 cups (1 liter) vegetable broth
  • 1 cup (240 ml) coconut milk or heavy cream
  • Salt and pepper, to taste

Instructions

  1. Roast the Sweet Potatoes: Preheat your oven to 400°F (200°C). Place 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 a few pieces aside for garnish if desired.
  2. Sauté the Aromatics: In a large pot, heat 2 tablespoons of olive oil over medium heat. Add diced onion and sauté for about 5 minutes until softened. Add 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 followed by the vegetable broth. Stir to combine and bring to a boil. Reduce heat and simmer gently for 10-15 minutes to meld flavors together.
  4. Blend the Soup: Use an immersion blender to puree the soup until smooth and creamy. For a finer texture, transfer 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 reserved roasted sweet potato wedges and a sprig of fresh thyme. Serve warm and enjoy!

Notes

  • For extra flavor and depth, add carrots or parsnips along with the sweet potatoes when roasting.
  • Spice it up with a pinch of red pepper flakes if desired.
  • Use coconut milk for a vegan, dairy-free version or heavy cream for a richer, traditional texture.
  • Fresh herbs like thyme or rosemary make great garnishes for an added vibrant touch.
  • Store leftovers in an airtight container refrigerated up to 4 days or freeze for up to 3 months. Reheat gently with water or broth if too thick.
