This Roasted Italian Sweet Potato Soup is the cozy hug your weeknight dinner needs. Velvety smooth with a delicate balance of sweet and savory, this soup turns humble ingredients into something elegant and satisfying. The sweetness of roasted sweet potatoes is deepened in the oven, then blended with garlic, onion, herbs, and a touch of Parmesan for a silky, rustic bowl that warms you from the inside out.

What Kind of Sweet Potatoes Should I Use?

For the best flavor and texture, use orange-fleshed sweet potatoes. Varieties like Jewel or Garnet are ideal as they have a naturally creamy consistency once roasted and blend beautifully into soups. Their earthy sweetness contrasts perfectly with savory Italian herbs.

Ingredients for the Roasted Italian Sweet Potato Soup

Sweet Potatoes – The hero of this dish, roasted for enhanced sweetness and depth.

Olive Oil – Adds richness and helps caramelize the veggies during roasting.

Yellow Onion – Brings a subtle sweetness and savory backbone to the soup.

Garlic Cloves – Roasted along with the potatoes for a mellow, nutty flavor.

Vegetable Broth – Keeps the soup light yet flavorful; you can sub chicken broth if preferred.

Dried Italian Herbs – A blend of oregano, thyme, basil, and rosemary infuses the soup with comforting aroma.

Salt + Black Pepper – Enhances all the flavors; adjust to taste.

Parmesan Cheese – Adds umami and a creamy finish. Omit for dairy-free or use nutritional yeast.

Fresh Sage or Thyme (optional garnish) – For a fragrant and visually inviting topping.

How To Make the Roasted Italian Sweet Potato Soup

Step 1: Roast the Vegetables

Preheat your oven to 400°F (200°C). Peel and cube the sweet potatoes, slice the onion, and peel the garlic cloves. Spread everything on a baking sheet, drizzle with olive oil, sprinkle with salt, pepper, and half of the dried Italian herbs. Roast for 25-30 minutes until the sweet potatoes are tender and lightly caramelized.

Step 2: Blend the Soup Base

Once roasted, transfer the vegetables to a blender or a large pot if using an immersion blender. Add the vegetable broth and remaining herbs. Blend until completely smooth and velvety. Add more broth as needed to reach your desired consistency.

Step 3: Warm and Finish

Pour the blended soup into a pot over medium heat. Stir in the grated Parmesan and let it melt into the soup, adding extra salt and pepper to taste. If the soup feels too thick, add a splash more broth.

Step 4: Garnish and Serve

Ladle into bowls and garnish with fresh sage leaves, extra cracked black pepper, or a drizzle of olive oil. Serve hot with a slice of crusty bread or a grilled cheese for a complete meal.

How to Serve and Store Roasted Italian Sweet Potato Soup

This soup is best served hot, straight from the pot, topped with fresh herbs or a swirl of cream. It pairs beautifully with rustic sourdough bread, crostini, or a sharp green salad. For added texture, sprinkle with toasted pumpkin seeds or croutons.

To store, allow the soup to cool completely, then transfer it into an airtight container. It will keep in the refrigerator for up to 5 days. For longer storage, freeze in individual portions for up to 3 months. Reheat gently on the stovetop or in the microwave, adding a splash of broth or water if needed to loosen the texture.

Frequently Asked Questions

How can I make this soup vegan?

Simply omit the Parmesan or replace it with nutritional yeast for a cheesy flavor without dairy. Be sure to use vegetable broth instead of chicken.

What herbs work best in this soup?

Italian herb blends are ideal—think oregano, basil, thyme, and rosemary. Fresh sage or thyme as a garnish adds a fragrant finishing touch.
