Sweet Potato Carrot Soup Recipe

This soup is a nod to those quiet evenings when I want something hearty but not heavy, with a touch of earthiness that feels like a warm hug. I love roasting the sweet potatoes and carrots until they’re caramelized—those little charred edges add a smoky depth I can’t resist. It’s the kind of dish that feels like a simple act of kindness, especially when the air gets crisper outside.

Growing up, I’d often help my mom peel and chop these roots, their vibrant orange and deep amber colors brightening up our kitchen. Now, I carry that nostalgic warmth into my own cooking, aiming for a bowl that’s smooth, sweet, and just a little rustic. It’s perfect for slowing down, for savoring each spoonful as a reminder of home, no matter where I am.

This recipe is inspired by my childhood summers in rural Vermont, where I learned to love the simple pleasure of digging into a warm bowl of soup after a long day outdoors. It’s not just about nourishment but capturing a moment of nostalgia—like the earthy sweetness of roasted carrots and sweet potatoes blending into a comforting, smoky broth. I want every spoonful to feel like a cozy memory, a quiet pause amid chaos.

Root Vegetable Comfort

• Making this soup always takes me back to summer evenings in my grandmother’s garden, where the scent of roasted carrots and sweet potatoes filled the air, warm and earthy.
• There’s a quiet pride I feel when I blend these humble roots into a silky, vibrant bowl—reminding me that simple ingredients can create something truly comforting.
• Sometimes, I get overwhelmed by the chaos of the week, but a bowl of this soup feels like a gentle reset, grounding me in a moment of warmth and familiarity.

The story behind this recipe

This soup came about one chilly weekend when I was rummaging through my pantry, trying to use up some forgotten sweet potatoes and carrots. I remembered how my grandmother used to roast root vegetables, filling the house with a sweet, smoky aroma that made everything feel a little cozier. I wanted a dish that captured that warmth, but with the simplicity of blending everything into a smooth, comforting bowl. It’s become a go-to when I need something honest and satisfying, with just a hint of nostalgia.

Trivia & Historical Notes

• This soup’s roots trace back to rustic European traditions, where root vegetables were a staple for winter sustenance.
• Sweet potatoes and carrots became popular in Western diets during the 20th century, often cooked together in hearty, humble dishes.
• The combination of sweet and earthy flavors in this soup echoes indigenous and colonial influences, blending native ingredients with European cooking methods.

Ingredient breakdown

• Sweet potatoes: I love their natural oozy sweetness when roasted, but you can swap in butternut squash for a milder, creamier texture that still keeps the soup vibrant.
• Carrots: Their bright, almost lemony aroma when cooked is what makes this dish special. If unavailable, parsnips bring a similar earthy sweetness with a slightly spicier undertone.
• Onion: Adds depth and a gentle sweetness—don’t skip it. If you’re out, leeks can be a lovely substitute, offering a milder, more delicate flavor.
• Garlic: I use a lot for that punch of warmth. If you’re sensitive to raw garlic, roasting it first mellows the flavor and adds a smoky nuance.
• Vegetable broth: I prefer homemade, but store-bought works fine. For richer flavor, a splash of coconut milk or a splash of apple cider vinegar can brighten it up.
• Olive oil: I use a good drizzle for roasting—if you only have neutral oil, the soup will still be flavorful, just a bit less fruity and rich.
• Seasonings: Salt and pepper are enough, but a pinch of smoked paprika or cumin can add a subtle smoky or warm spice note that enhances the earthy sweetness.

Equipment & Tools

• Baking sheet: Roast vegetables evenly
• Parchment paper: Prevent sticking and easy cleanup
• Sharp knife: Chop and prepare vegetables
• Large pot: Cook and blend soup
• Immersion blender: Puree soup smoothly directly in the pot
• Measuring cups and spoons: Measure liquids and seasonings accurately

Step-by-step guide to Sweet Potato Carrot Soup

1. Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper. Gather 2 large sweet potatoes and 4 carrots, peeled and cut into chunks about 3cm (1 inch) thick.
2. Toss the sweet potatoes and carrots with 2 tablespoons of olive oil, a pinch of salt, and a teaspoon of smoked paprika if using. Spread evenly on the baking sheet.
3. Roast in the oven for 30-35 minutes until caramelized around the edges and soft inside. The aroma should be sweet and smoky, and the vegetables should be easily pierced with a fork.
4. While roasting, finely chop 1 large onion and 3 cloves of garlic. Heat 1 tablespoon of olive oil in a large pot over medium heat (about 160°C/320°F).
5. Add onion and garlic to the pot. Sauté for 5-7 minutes until fragrant and translucent, stirring occasionally. It should smell sweet and slightly nutty.
6. Once vegetables are roasted, transfer them to the pot. Pour in 4 cups of vegetable broth. Bring to a gentle simmer, about 10 minutes, to meld flavors.
7. Use an immersion blender to purée the soup directly in the pot until smooth and velvety. If using a regular blender, blend in batches, then return to the pot.
8. Taste and adjust seasoning with salt and pepper. If too thick, add a splash more broth; if too thin, simmer a few more minutes until slightly reduced.
9. Ladle the hot soup into bowls. Garnish with a drizzle of olive oil, a sprinkle of fresh herbs, or a dollop of yogurt if desired.
10. Let the soup rest for 5 minutes before serving to allow flavors to settle. Serve hot, with crusty bread on the side.

Let the soup sit for 5 minutes to deepen flavors. Serve in warm bowls, garnished as desired. For a richer finish, swirl in a little coconut milk or olive oil before serving.

How to Know It’s Done

• Vegetables are caramelized and soft when roasted.
• Onion and garlic are fragrant and translucent when sautéed.
• Soup is velvety smooth with no lumps after blending.

Pro tips for perfect soup

• Use a high-quality olive oil for roasting—its fruity aroma enhances sweetness and adds depth.
• Ensure vegetables are evenly coated with oil and seasoning—this promotes uniform caramelization.
• When roasting, spread vegetables in a single layer—crowding causes steaming, not roasting.
• Sauté onions and garlic until fragrant and translucent—this builds a rich flavor base.
• Purée the soup while still warm—this helps achieve a silky, smooth texture without lumps.
• Taste and adjust seasoning at the end—salt and a splash of acid brighten the finished bowl.
• For a smoky twist, sprinkle a pinch of smoked paprika before blending—adds depth and warmth.

Common mistakes and how to fix them

• FORGOT to check vegetable caramelization—do it visually, not just timer.
• DUMPED the roasted vegetables directly into boiling broth—let them cool slightly first.
• OVER-TORCHED the garlic—roast at lower heat if it starts to burn.
• UNDERESTIMATED the seasoning—taste and adjust before blending.

Fast kitchen fixes

• If soup is too thick, splash in hot broth and stir well to loosen.
• When vegetables stick, turn up oven heat slightly or extend roasting time.
• Splash a bit of lemon juice if flavors are dull or flat.
• Patch burnt garlic by adding a few fresh cloves to boost aroma.
• Shield bubbling soup with a lid if it shimmers and splatters during reheating.

Prep, store, and reheat tips

• You can roast the sweet potatoes and carrots a day ahead; let them cool completely before refrigerating, which keeps flavors fresh and sweet.
• Store the roasted vegetables in an airtight container for up to 2 days in the fridge; they’ll develop a deeper caramelized flavor overnight.
• Reheat the roasted vegetables gently in the oven or microwave until warmed through, which helps preserve their texture and smoky aroma.
• The soup itself can be made a day in advance; store in an airtight container in the fridge for up to 3 days, with the lid slightly cracked for the first hour to prevent condensation buildup.
• Reheat on the stove over medium-low heat, stirring occasionally; check for even warmth and adjust seasoning if needed, ensuring it remains velvety and fragrant.

Top questions about Sweet Potato Carrot Soup

1. Can I skip peeling the vegetables?

Yes, peeling is optional if you prefer a more rustic look, but it helps achieve a smoother texture. The skin adds fiber and a slightly earthy flavor if left on.

2. Can I cook the vegetables differently?

Absolutely. Roasting brings out natural sweetness and smoky notes, but you can also boil or steam the vegetables if you prefer a quicker method.

3. Can I use different liquids instead of broth?

Yes, you can replace the vegetable broth with chicken broth or water, but the flavor will be less rich. For a vegan version, use mushroom broth for umami depth.

If the soup is too thick, add a splash of hot water or broth and blend again. If too thin, simmer a bit longer until it thickens to your liking.

5. How can I make it creamier?

You can add a splash of cream, coconut milk, or a dollop of yogurt for extra creaminess. These additions also enhance richness and flavor complexity.

6. How should I store and reheat leftovers?

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently over low heat, stirring often, until steaming hot and fragrant.

7. Can I spice up the soup?

Yes, adding a pinch of smoked paprika or cumin during blending elevates the earthy sweetness with smoky or warm spice notes, enriching the flavor profile.

8. Is this soup gluten-free?

For a gluten-free option, serve with crusty bread or a grain like quinoa on the side. Just check the bread ingredients if needed.

9. What are good toppings?

You can top the soup with toasted seeds, chopped herbs, or a drizzle of olive oil. These add texture and fresh flavor contrasts.

10. Can I use a blender instead of an immersion blender?

Yes, blending the soup in batches with a little water or broth works fine if your immersion blender isn’t available. Just be careful and blend carefully to avoid splashes.
