Introduction

This Roasted Italian Sweet Potato Soup is a cozy and comforting dish, perfect for chilly days. Roasted sweet potatoes provide natural sweetness and a velvety texture, while Italian herbs bring a fragrant Mediterranean twist. Easy to make and wonderfully creamy, it’s sure to warm you up from the inside out.

A white speckled bowl holds a thick, creamy soup with a light orange-beige color and small chunks of orange vegetable pieces scattered throughout. Three charred, golden-brown roasted vegetable sticks rest on one side of the bowl, partially dipping into the soup. A small green herb sprig with tiny leaves is placed delicately on top near the vegetable sticks. The bowl sits on a white marbled surface, and a silver spoon is visible inside the bowl next to the roasted sticks. photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 large sweet potatoes, peeled and cut into wedges (~600 g)
2 tbsp (30 ml) olive oil (plus extra for roasting)

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
4 cups (1 liter) vegetable broth
1 cup (240 ml) coconut milk or heavy cream

Salt and pepper to taste

Instructions

Step 1: 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 pieces aside for garnish if desired.
Step 2: 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. Add the minced garlic, dried thyme, rosemary, and basil, and cook for another 1-2 minutes until fragrant.

Step 3: Add the roasted sweet potatoes to the pot along with the vegetable broth. Stir well and bring to a boil. Reduce heat and simmer for 10-15 minutes to meld the flavors.
Step 4: Use an immersion blender to puree the soup until smooth and creamy. Alternatively, blend in batches using a regular blender. Stir in the coconut milk or heavy cream and heat through for 5 minutes. Season with salt and pepper to taste.
Step 5: Ladle the soup into bowls. Garnish with reserved roasted sweet potato wedges and a sprig of fresh thyme. Serve warm and enjoy.

Tips & Variations

Roast the sweet potatoes to caramelize their sugars, enhancing the soup’s natural sweetness and depth.
Add extra vegetables like carrots or parsnips with the sweet potatoes for more complexity.
For a spicy kick, sprinkle in a pinch of red pepper flakes.

Use coconut milk for a vegan option or heavy cream for a richer, traditional texture.
Garnish with fresh thyme or rosemary to brighten the flavors before serving.

Storage

Store the soup in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze it in a freezer-safe container for up to 3 months. Reheat gently on the stovetop or in the microwave, adding a little water or broth if the soup becomes too thick.

How to Serve

A creamy orange soup with small bits of darker and lighter orange vegetables spread evenly throughout fills a white speckled bowl. On top, there are three grilled orange sweet potato sticks with char marks, leaning slightly to the side. A small green sprig of thyme rests beside the potato sticks in the soup, adding a touch of freshness. The bowl sits on a white marbled surface with soft lighting highlighting the smooth, slightly thick texture of the soup. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use yams instead of sweet potatoes?

Yes, yams can be used, but they have a slightly different flavor and texture. True sweet potatoes offer the best natural sweetness for this soup.

Is there a substitute for coconut milk?

If you prefer a dairy-based option, heavy cream or half-and-half works well. For a dairy-free substitute without coconut flavor, almond or oat milk will give a lighter texture.
