- They caramelize slightly during roasting, developing a sweet, nutty aroma.
Miso Paste:
- Miso: It’s salty, savory, and rich—adding a complex umami punch that transforms the soup.
- Different types have distinct flavors: white is mild and sweet, red is robust and earthy.
Ingredient substitutions for flexibility
- Sweet Potato: Swap with butternut squash for a slightly milder, nuttier flavor.
- Carrots: Use parsnips for a sweeter, more floral note.
- Miso: Tamari or soy sauce can add umami if miso isn’t available.
- Olive oil: Avocado oil for a neutral, high-smoke option.
- Vegetable broth: Water plus a teaspoon of miso for a lighter version.

Step-by-step guide to perfect sweet potato carrot soup
- Peel and chop 2 large sweet potatoes and 3 carrots into roughly 2 cm pieces.
- Heat 2 tbsp olive oil in a large pot over medium heat, about 160°C (320°F).
- Add the chopped vegetables, a pinch of salt, and cook, stirring occasionally, until they start to soften and turn golden—about 8 minutes.
- Pour in 4 cups vegetable broth and bring to a gentle simmer. Cover and cook until the vegetables are very tender—about 20 minutes.
- Remove from heat, and using an immersion blender or regular blender in batches, purée until smooth. Be careful—hot splashes happen.
- Return the soup to low heat, stir in 1 tbsp miso paste, and heat through for 2 minutes, but don’t boil—miso loses flavor.
- Taste and adjust salt or add a splash more broth if too thick. Serve hot, garnished with seeds or a dollop of yogurt.
Allow the soup to rest off the heat for 5 minutes before serving to let flavors meld. Finish with a drizzle of oil or a sprinkle of seeds.

Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F). Peel the sweet potatoes and carrots, then chop them into roughly 2 cm pieces. Spread them evenly on a baking sheet, drizzle with 1 tablespoon of olive oil, and toss to coat. Roast for about 20-25 minutes until they are tender and slightly caramelized, filling your kitchen with a sweet, earthy aroma.
- While the vegetables roast, heat the remaining 1 tablespoon of olive oil in a large pot over medium heat. Once warm, add the roasted vegetables and sauté gently for 2-3 minutes, allowing their flavors to meld and their edges to begin to soften.
- Pour in the vegetable broth, bringing the mixture to a gentle simmer. Cover the pot, and cook for another 10 minutes, giving the flavors time to deepen and the vegetables to become very tender.
- Remove the pot from heat. Use an immersion blender directly in the pot or carefully transfer the mixture to a blender in batches. Puree until the soup is completely smooth and velvety, with a bright, rich orange color. Be cautious of hot splashes during blending.
- Stir in the miso paste, blending thoroughly to incorporate. Warm the soup gently over low heat for 2 minutes—avoid boiling, as high heat can diminish miso’s flavor. Taste and add salt if needed.
- Serve the soup hot in bowls, garnished with a sprinkle of seeds or a dollop of yogurt. Drizzle with a little extra olive oil if desired, and enjoy the comforting, silky texture and layered flavors with every spoonful.
