Spotlight on sweet potatoes and carrots
Sweet Potatoes:
- Their silky flesh becomes luxuriously smooth when pureed. Watch during roasting—they can burn easily if left too long.
- Carrots: They develop a caramelized flavor when roasted, adding a smoky note. Fresh ones are crisper and brighter in flavor.
Carrots:
- When cooked, they soften and release a sweet aroma. Larger carrots may need a longer roast.

Roasted Sweet Potato and Carrot Soup
Ingredients
Equipment
Method
- Preheat your oven to 200°C (390°F). Line a baking sheet with parchment paper for easy cleanup.
- Peel and chop the sweet potatoes and carrots into evenly-sized chunks for uniform roasting. Place them in a bowl, toss with a tablespoon of olive oil, and season with a pinch of salt and pepper.
- Spread the coated vegetables evenly on the prepared baking sheet. Roast for about 25-30 minutes until they are golden around the edges and caramelized, filling your kitchen with a sweet, smoky aroma.
- While the vegetables roast, chop the onion finely. In a large pot, heat a tablespoon of olive oil over medium heat. Sauté the onion until it becomes translucent and fragrant, about 5 minutes.
- Once the roasted vegetables are ready and cooled slightly, add them to the pot with the sautéed onion. Pour in the vegetable broth and bring the mixture to a gentle simmer.
- Let the soup simmer uncovered for about 10 minutes, allowing the flavors to meld and the vegetables to soften further. The aroma will deepen, hinting at smoky sweetness.
- Use an immersion blender to carefully blend the soup directly in the pot until smooth and velvety. Alternatively, transfer the soup in batches to a blender and purée until creamy.
- Taste the soup and adjust the seasoning with salt and freshly ground pepper. Stir in the lemon juice to add brightness and balance the sweetness of the vegetables.
- Warm the soup for another few minutes, then ladle into bowls. Garnish with fresh herbs or a swirl of coconut milk if desired, and serve hot.
