Roasted Sweet Potato Carrot Soup
Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F). Arrange the peeled and chopped sweet potatoes and carrots on a baking sheet, then toss them with a tablespoon of olive oil, salt, and pepper until evenly coated. Roast for 30-35 minutes, or until the vegetables are caramelized and tender, filling your kitchen with a sweet, roasted aroma.
- While the vegetables roast, peel a few garlic cloves and set them aside. Once the vegetables are done, add the garlic to the sheet and roast for an additional 10 minutes, allowing the garlic to mellow and develop a sweet, nutty flavor.
- Remove the roasted vegetables and garlic from the oven. Let the garlic cool slightly, then squeeze the softened cloves out of their skins. Place the roasted vegetables and garlic into a large pot, along with the vegetable broth.
- Heat the large pot over medium heat and add a splash of olive oil. Sauté chopped onion (if using) for about 5 minutes until translucent and fragrant—this step is optional but adds depth to the flavor.
- Bring the mixture to a gentle simmer and cook for 10 minutes, allowing the flavors to meld and the vegetables to soften further.
- Use an immersion blender directly in the pot to purée the soup until smooth and velvety. Alternatively, carefully transfer the hot mixture to a blender in batches, blending until silky, then return to the pot.
- Taste the soup and adjust the seasoning with salt and pepper. For brightness, add a squeeze of lemon or a splash of vinegar if desired.
- Serve the soup hot in bowls, garnished with a drizzle of olive oil or fresh herbs for added flavor and presentation.
Notes
Pro tips for perfect soup every time.
- Roasting at high heat caramelizes the sugars, boosting flavor.
- Use immersion blender for smooth texture—less mess and quicker cleanup.
- Add lemon juice or vinegar at the end to brighten the sweetness.
- Salt in stages—season during cooking and at the end for layered flavor.
- Keep a close eye on the garlic—burnt garlic turns bitter quickly.
Common pitfalls and how to fix them.
- FORGOT to roast enough vegetables? Add a splash of smoky paprika or chipotle powder for depth.
- DUMPED too much broth? Simmer uncovered longer to thicken or add a handful of cooked rice for creaminess.
- OVER-TORCHED the garlic? Remove the burnt bits quickly, and add fresh garlic to revive the aroma.
- SCOURED the soup while blending? Pass it through a fine sieve to remove lumps and bits.
Fast fixes to rescue your soup.

- When bland, add a squeeze of lemon or splash of vinegar.
- Splash a bit of cream or coconut milk for richness.

Preparing and storing leftovers without losing flavor.
- Roasted vegetables can be prepared up to 2 days in advance and kept in the fridge.
- Soup can be stored in the fridge for 3-4 days, or frozen for up to 3 months.
- Reheat on the stove over low heat, stirring occasionally, until steaming.
- Adding a splash of broth during reheating keeps the soup from drying out and enhances flavor.
