Key ingredients at a glance
- Sweet potatoes: I prefer a dense, oily variety like Beauregard for natural sweetness and creamy texture; swap with butternut squash if needed, but expect a softer, milder flavor.
- Carrots: Bright orange, crunchy when raw, but become tender and sweet when roasted. Use heirloom carrots for more complex flavor—substitute with parsnips for a rootier twist.
- Onion: Adds a savory base; I use yellow onions for sweetness. Red onions give a sharper bite, so consider milder shallots if you want a gentler start.
- Garlic: Roasting mellows garlic into a sweet, smoky note. Skip if sensitive to strong flavors, but don’t skip the garlic, it’s key for depth.
- Smoked paprika: Brings a subtle smoky warmth. Use regular paprika for a milder touch, or chipotle powder if you want more heat and smoky intensity.
- Vegetable broth: I use homemade or store-bought, but if you want richer flavor, a splash of miso or a dash of soy can add umami without overpowering.
- Olive oil: I love a good extra virgin for roasting; it crisps edges nicely and adds fruity undertones. Swap with coconut oil for a faint sweetness and tropical aroma.

Step-by-step guide to sweet potato carrot soup
- Gather your equipment: a large heavy-bottomed pot or Dutch oven, a chef’s knife, a cutting board, a baking sheet, and an immersion blender or regular blender.
- Preheat your oven to 200°C (400°F).
- Peel the sweet potatoes and carrots. Cut the sweet potatoes into 2-inch chunks, and the carrots into similar-sized pieces for even roasting.
- Spread the sweet potato and carrot chunks on a baking sheet. Drizzle with 2 tbsp olive oil, sprinkle with salt, and toss to coat.
- Roast in the oven for about 25-30 minutes, or until the edges are caramelized and the vegetables are tender when pierced with a fork. The smell should be sweet and smoky.
- While the veggies roast, dice 1 large onion and 3 cloves garlic.
- In the pot, heat 1 tbsp olive oil over medium heat (about 160°C/320°F).
- Add the diced onion and cook for about 5-7 minutes, stirring occasionally, until translucent and fragrant. It should smell sweet and earthy.
- Add the garlic and cook for another minute until fragrant but not burnt; if it turns bitter, reduce heat slightly.
- Once the roasted vegetables are ready, add them to the pot.
- Pour in 4 cups vegetable broth and bring the mixture to a gentle simmer over medium-low heat (about 85°C/185°F).
- Let simmer for 10 minutes to allow flavors to meld, stirring occasionally.
- Use an immersion blender to purée the soup directly in the pot, or transfer to a blender in batches. Blend until smooth and velvety. If the soup feels too thick, add a splash more broth or water.
- Taste and adjust seasoning with salt and a pinch of smoked paprika for extra smoky warmth.
- Pour the soup into bowls, garnish with a drizzle of olive oil or a sprinkle of herbs if desired, and serve hot.
Once blended, let the soup sit for a few minutes to settle. Serve hot in bowls, garnished as desired, and enjoy the warm, smoky aroma.

Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F) and prepare a baking sheet lined with parchment paper.
- Peel the sweet potatoes and carrots, then cut them into roughly 2-inch chunks for even roasting.
- Spread the chopped vegetables on the baking sheet, drizzle with 2 tablespoons of olive oil, sprinkle with a pinch of salt, and toss gently to coat everything evenly.
- Roast the vegetables in the oven for about 25-30 minutes, until they are golden around the edges and deeply caramelized, with a sweet, smoky aroma filling the air.
- Meanwhile, peel and dice the onion, then chop the garlic cloves.
- In a large pot, heat 1 tablespoon of olive oil over medium heat until it shimmers and smells slightly nutty.
- Add the diced onion to the pot and sauté for 5-7 minutes, stirring occasionally, until translucent and fragrant with a sweet aroma.
- Add the chopped garlic to the onion and cook for another minute, just until fragrant, taking care not to burn it.

- Pour in the vegetable broth and stir everything together. Bring to a gentle simmer over medium-low heat, and let cook for 10 minutes to meld the flavors.

Notes
Pro tips for perfect soup
- Use a high-quality smoked paprika to get a deep, smoky aroma that permeates the soup.
- Roast vegetables until edges are caramelized for a sweeter, richer flavor and a slightly crispy texture.
- Blend the soup while still warm to ensure a silky, velvety texture without lumps.
- Taste and adjust seasoning at the end—sometimes a pinch more salt or paprika makes a big difference.
- Keep an eye on the soup as it simmers—avoid boiling vigorously to prevent splattering and over-reduction.
- For a brighter flavor, add a squeeze of lemon juice just before serving to highlight the sweetness.
- Use an immersion blender for easy puréeing directly in the pot, but a regular blender works fine if careful with hot liquids.
Common mistakes and how to fix them
- FORGOT to adjust heat: Vegetables may burn; lower oven or pan heat accordingly.
- DUMPED too much liquid: Reduce simmering time or blend partially for thicker texture.
- OVER-TORCHED the vegetables: Remove early if edges burn; roasting time varies by oven.
- MISSED seasoning balance: Taste before blending; add salt or spices gradually for depth.
Quick fixes and pantry swaps
- When soup is too thick, splash in more broth and blend briefly for a smoother texture.
- If the aroma isn’t smoky enough, sprinkle a bit more smoked paprika on top before serving.
- Splash a teaspoon of lemon juice when the soup feels dull to brighten flavors instantly.
- Patch burnt edges by scooping out unburned vegetables and adding fresh ones to the mix.
- Shield delicate garlic from over-torching by adding it later in the cooking process if it browns too quickly.
Prep, store, and reheat tips
- Peel and chop the sweet potatoes and carrots a day ahead; store in an airtight container in the fridge for up to 24 hours. The natural sugars start to oxidize if left too long, so prep close to cooking time for best flavor.
- Roast the vegetables ahead of time and keep in a sealed container in the fridge for up to 2 days. Reheat in a low oven or microwave until warmed through. The caramelized edges may soften but still add depth to the soup.
- The soup can be made entirely a day in advance. Once cooled, store in an airtight container in the fridge for up to 3 days. Reheat gently on the stove, stirring occasionally, until it’s steaming hot and smells inviting—should be smooth and fragrant, not watery.
- For longer storage, freeze the cooled soup in portions for up to 3 months. Thaw overnight in the fridge and reheat as above. Expect some separation; give it a good stir to bring back the velvety texture and smoky aroma.
Frequently Asked Questions
1. Can I leave the skins on?
Peeling the sweet potatoes and carrots makes the soup smoother. You can skip peeling if the skin is thin and scrubbed well, but expect a slightly earthier texture.
2. Is roasting necessary?
Roasting enhances natural sweetness and adds a smoky flavor. If you skip roasting, just simmer the vegetables until tender, but you’ll miss out on that caramelized depth.
3. Should I add acid?
Adding a splash of lemon juice brightens the soup and balances the sweetness. If you don’t have lemon, a little vinegar works as a good substitute.
4. Can I use a blender instead of an immersion blender?
Use an immersion blender for quick, easy puréeing directly in the pot. If you prefer, transfer in batches to a regular blender, but be careful with hot liquids to avoid splashes.
5. Can I substitute smoked paprika?
Smoked paprika adds a subtle smoky warmth. For more heat and smoky intensity, try chipotle powder; for milder flavor, stick with regular paprika.
6. How long does it last in the fridge?
The soup keeps well in the fridge for up to 3 days. Reheat gently on the stove until steaming and fragrant, adjusting with a splash of broth if it thickens too much.
7. Can I freeze leftovers?
You can freeze the soup in airtight containers for up to 3 months. Thaw overnight in the fridge and reheat until hot, stirring well to restore its velvety texture.
8. What if the soup is too thick or thin?
If the soup turns out too thick, stir in a little more broth or water and blend briefly. If it’s too thin, simmer gently uncovered until it thickens to your liking.
9. How do I prevent garlic from burning?
Overcooking garlic can make it bitter. Add garlic towards the end of sautéing, just until fragrant, to keep its sweet, mellow flavor.
10. What ingredients should I look for?
Using high-quality, fresh vegetables makes a big difference. Look for sweet potatoes with firm, smooth skin and bright orange carrots for the best flavor and color.
