How to Make Roasted Italian Sweet Potato Soup Recipe

Step 1: Roast the Sweet Potatoes

First things first: preheat your oven to 400°F (200°C). Arrange the sweet potato wedges on a baking sheet, drizzle them generously with olive oil, and sprinkle with salt and pepper. Roasting transforms these sweet potatoes, caramelizing their edges and concentrating their natural sugars, which is key to the soup’s signature deep flavor. Roast for about 25 to 30 minutes until tender and golden, then set a handful aside for a delightful garnish later.

Step 2: Sauté the Aromatics

While the sweet potatoes roast, warm 2 tablespoons of olive oil in a large pot over medium heat. Toss in the diced onion and cook for about 5 minutes, stirring occasionally until the onion softens and releases its gentle sweetness. Next, add the minced garlic along with the dried thyme, rosemary, and basil. Cook for another 1 to 2 minutes, letting those beautiful aromas fill your kitchen and awaken your appetite.

Step 3: Combine and Simmer

Now it’s time for the magic to come together. Add the roasted sweet potatoes to your pot, then pour in the vegetable broth. Give everything a good stir to combine the flavors, then bring the mixture to a boil. Once boiling, reduce the heat to a gentle simmer. Let all those flavors mingle intimately for 10 to 15 minutes, giving the herbs room to infuse their enchanting essence into the soup.

Step 4: Blend the Soup

Using an immersion blender right in the pot, puree the soup until it becomes luxuriously smooth and creamy. If you want a silkier texture, you can transfer the soup in batches to a regular blender for a finer blend. Once smooth, stir in the coconut milk or heavy cream and heat through for another 5 minutes. Don’t forget to season with salt and pepper to perfectly balance the flavors before serving.

Step 5: Serve

Ladle your warm soup into bowls, then decorate each serving with a few reserved roasted sweet potato wedges and a sprig of fresh thyme. This little flourish not only looks inviting but also adds a lovely texture contrast and burst of fresh herbal aroma. Now feast on this beautiful creation!

Garnishes

Garnishes are where you can get playful and elevate your soup visually and aromatically.

A drizzle of extra virgin olive oil or a sprinkle of chili flakes can introduce richness or gentle heat, making each bowl uniquely yours.

Side Dishes

A simple arugula salad with lemon vinaigrette or a light antipasto platter featuring olives, cheeses, and cured meats perfectly complements the soup’s smooth, earthy flavors without overpowering them.

Creative Ways to Present

Serve the soup in rustic bowls for a homey vibe or elegant white crockery for dinner guests. Swirl some cream or coconut milk on top for an inviting marbled effect, or top with toasted pumpkin seeds for added crunch. For a fun twist, turn it into a soup shooter or serve alongside grilled polenta squares as finger food at your next gathering.

Make Ahead and Storage

Storing Leftovers

If you find yourself lucky enough to have leftovers, store your soup in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen with time, making reheated portions just as delightful as when freshly made. Just give it a good stir before serving to recombine any separated cream or broth.

Freezing

This Roasted Italian Sweet Potato Soup Recipe freezes wonderfully. Let the soup cool completely, then transfer to freezer-safe containers or bags. It will keep for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating gently on the stove.

Reheating

Reheat your soup gently over medium-low heat, stirring occasionally until warmed through. If it feels a little thick after storage, add a splash of vegetable broth or water to loosen it up to your preferred consistency. Taste and adjust the seasoning if needed to refresh those beautiful herb notes.

FAQs

Can I use fresh herbs instead of dried for this recipe?

Absolutely! Fresh herbs can brighten the flavor even more. Use about three times the amount of fresh herbs compared to dried, and add some fresh sprigs toward the end of cooking or as garnish for maximum aroma.

Is there a vegan option for this soup?

Yes! Simply swap out the heavy cream for coconut milk, which adds a lovely creaminess while keeping the soup dairy-free and vegan-friendly without compromising flavor.

What can I do if I don’t have an immersion blender?

No worries if you don’t have an immersion blender. Carefully transfer the soup in batches to a regular blender, blend until smooth, and then return it to the pot for the final step. Just be mindful of hot liquid safety!

Can I add other vegetables to the soup?

Definitely! Carrots or parsnips roast beautifully with the sweet potatoes and add extra depth. Just chop them similarly and roast along with the potatoes before adding to the soup.

How spicy is this soup? Can I make it spicy?

This Roasted Italian Sweet Potato Soup Recipe is mild and comforting by default. You can easily spice it up by sprinkling in some red pepper flakes during the sauté step or adding a dash of hot sauce when serving.
