How to Make Roasted Italian Sweet Potato Soup

Step 1: Roast the Sweet Potatoes

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 a few wedges aside for garnish.

Step 2: Sauté Aromatics

In a large pot, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté for 5 minutes until softened. Add minced garlic, thyme, rosemary, and basil, cooking for another 1–2 minutes until fragrant.

Step 3: Combine and Simmer

Add the roasted sweet potatoes to the pot along with the vegetable broth. Stir and bring to a boil. Reduce heat and simmer for 10–15 minutes to allow flavors to meld.

Step 4: Blend the Soup

Use an immersion blender to puree the soup until smooth. For a finer texture, blend in batches using a regular blender. Stir in coconut milk or heavy cream and heat through for 5 more minutes. Season with salt and pepper to taste.

Step 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!
