The Root of It All: Trivia and Context

Carrots were originally purple or white; the orange variety was developed in the Netherlands in the 17th century.

Tips & Tricks for a Flawless Soup
Use a heavy-bottomed pot for even heat distribution and to prevent scorching.

Roasted Sweet Potato and Carrot Soup
Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F). Spread the chopped sweet potatoes and carrots evenly on a large baking sheet, drizzling with olive oil and tossing to coat well. Roast for about 20 minutes, until the edges are golden and fragrant.
- While the vegetables roast, heat a tablespoon of olive oil in a large pot over medium heat. Add the diced onion and sauté for about 5 minutes until it becomes translucent and starts to smell sweet.
- Add the minced garlic to the onions, cooking for another 1-2 minutes until fragrant, taking care not to burn it.
- Remove the roasted vegetables from the oven once they are caramelized at the edges and soft inside. Carefully transfer them to the pot, adding any juices left on the baking sheet for extra flavor.
- Pour in the vegetable broth and bring the mixture to a gentle simmer. Reduce the heat to low, cover, and cook for about 20 minutes, allowing the flavors to meld and the vegetables to become very tender.
- Use an immersion blender to blend the soup directly in the pot until it is silky smooth. Alternatively, carefully transfer the hot mixture in batches to a blender and purée until velvety.
- Taste the soup and season with salt as needed. Add a splash of lemon juice for brightness if desired, stirring to combine.
