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 (plus extra sprigs for garnish)
  • 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 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 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 the diced onion and sauté for about 5 minutes until softened. Then add 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 to combine and bring to a boil. Reduce heat and let simmer for 10-15 minutes to meld flavors.
  4. Blend the Soup: Using an immersion blender, puree the soup until smooth and creamy. Alternatively, transfer in batches to a regular blender for a finer texture.
  5. Finish and Serve: Stir in the coconut milk or heavy cream and heat through for an additional 5 minutes. Adjust seasoning with salt and pepper to taste. Ladle into bowls and garnish with reserved roasted sweet potato wedges and fresh thyme sprigs. Serve warm and enjoy!

Notes

  • Use a baking sheet for roasting the sweet potatoes evenly.
  • A large pot is essential for sautéing aromatics and simmering the soup.
  • An immersion blender makes blending easier, but a regular blender works too.
  • Use a ladle to serve the hot soup cleanly.
  • For extra depth, add carrots or parsnips with the sweet potatoes when roasting.
  • Add a pinch of red pepper flakes if you desire a spicy kick.
  • For a vegan and dairy-free version, use coconut milk instead of heavy cream.
  • Garnish with fresh thyme or rosemary to enhance the herbal aroma and appearance.
