Ingredients for the Roasted Italian Sweet Potato Soup

Sweet Potatoes: The hero of the dish. Roasting enhances their natural sugars, adding sweetness and silkiness to the soup.

Garlic: Roasted alongside the potatoes for a mellow, rich flavor that infuses every spoonful.

Yellow Onion: Sautéed until golden, it adds savory depth to the soup base.

Olive Oil: Used for both roasting and sautéing; brings that signature Mediterranean richness.

Vegetable Broth: Forms the body of the soup, carrying the flavors and keeping it vegetarian-friendly.

Tomato Paste: Adds acidity and umami, balancing the sweetness of the potatoes.

Italian Seasoning: A blend of oregano, basil, thyme, and rosemary for classic flavor.

Crushed Red Pepper Flakes: Optional, but just a pinch adds subtle heat that warms from within.

Salt and Black Pepper: Essential to enhance and balance all the other flavors.

Heavy Cream: Just a touch swirled in at the end for a silky, restaurant-quality finish.

How To Make the Roasted Italian Sweet Potato Soup

Step 1: Roast the Vegetables

Peel and cube 2 pounds of sweet potatoes. Toss with 4 cloves of garlic (peeled) and 2 tablespoons of olive oil. Spread on a baking sheet and roast at 400°F for 30 minutes, flipping halfway through.

Step 2: Sauté the Base

In a large pot, heat 1 tablespoon olive oil over medium heat. Add 1 chopped yellow onion and cook for 5–7 minutes until softened and golden.

Stir in 2 tablespoons of tomato paste and cook for 1 minute to deepen the flavor. Add 1 teaspoon Italian seasoning, a pinch of red pepper flakes (optional), 1 teaspoon salt, and ½ teaspoon black pepper.

Step 4: Add Broth and Roast Veggies

Pour in 4 cups vegetable broth. Add the roasted sweet potatoes and garlic. Bring to a simmer for 10 minutes to meld flavors.

Step 5: Blend Until Smooth

Use an immersion blender to puree the soup until completely smooth. Alternatively, blend in batches using a countertop blender.
