Deep dive into the key ingredients.
- Sweet Potato: First-time I cooked it, I was surprised how sweet and starchy it becomes when roasted. Swap with butternut squash for a milder, nuttier flavor.
- Carrots: They add a bright, earthy sweetness. Use heirloom or purple carrots for color and a slightly different flavor profile.
- Onion: The base of any good soup—sauté until translucent, and it forms a sweet backdrop. Shallots can be a milder substitute.
- Vegetable Broth: The flavor foundation. Homemade broth adds depth, but store-bought works just fine.
- Citrus: Brightens everything. Lime or lemon zest can be used for a different zing.
Focus on sweet potato and carrots.
Sweet Potato:
- When roasting, it gets tender and develops a caramelized crust—think smoky-sweet aroma.
- It behaves well during blending—becomes velvety, almost buttery in texture.
- Choose firm, unblemished sweet potatoes for the best flavor and texture.
Carrots:
- They add a fresh, vegetal sweetness. During cooking, they soften and release their juice, enhancing the soup’s body.
- Opt for organic carrots if possible—they’re sweeter and more fragrant.
- Use a variety with deep orange color for maximum flavor and visual appeal.
Substitution options for different dietary needs or flavor tweaks.
- Dairy-Free: Use coconut milk or cashew cream for richness—adds a slightly sweet, nutty flavor.
- Vegan: Skip dairy; add extra spices or a splash of soy sauce for umami.
- Gluten-Free: No changes needed; this soup is naturally gluten-free.
- Low-Sodium: Use homemade broth or low-sodium stock to control salt.
- Extra Spicy: Add a dash of cayenne or chili flakes for heat.

Sweet Potato Carrot Soup
Ingredients
Equipment
Method
- Preheat your oven to 200°C (400°F). Chop the sweet potatoes into roughly 1-inch cubes and slice the carrots into rounds. Toss them with a tablespoon of oil and spread evenly on a baking sheet. Roast for 25-30 minutes until caramelized and fragrant.
- While the vegetables roast, peel and chop the onion. In a large pot, heat a tablespoon of oil over medium heat. Sauté the onion until translucent and soft, about 5 minutes, until it starts to smell sweet and turns a light golden color.
- Once the roasted vegetables are ready and cooled slightly, add them to the pot with the sautéed onions. Pour in the vegetable broth and bring the mixture to a gentle simmer. Let it cook for about 10 minutes to allow flavors to meld.
- Use an immersion blender directly in the pot, or carefully transfer the soup in batches to a blender. Blend until the soup becomes completely smooth and velvety, with no chunks remaining. Be cautious of hot splashes when blending.
- Taste the soup and season with salt and pepper. Add a splash of citrus juice or zest to brighten the flavors, stirring well to incorporate.
- Allow the soup to rest for 10 minutes off the heat, giving the flavors time to deepen and balance. Then, give it a final stir and check the seasoning again.
- Serve the soup hot, garnished with a drizzle of cream, herbs, or a sprinkle of extra citrus zest if desired. Enjoy the comforting, earthy goodness in every spoonful.
Pro tips for perfect soup every time.
- FLAVOR: Sear the vegetables until caramelized for richer taste.
- TEXTURE: Use an immersion blender for silky consistency—less mess.
- HEAT: Keep the simmer gentle—just a low bubble, to avoid breaking down the veggies too much.
- SPICE: Toast dried spices briefly in the pan before adding to release their aroma.
- BALANCE: Taste often—adjust acidity, salt, and sweetness as needed.
Common pitfalls and how to fix them.
- FORGOT TO roast the veggies? Roast longer or add a touch of smoked paprika for depth.
- DUMPED too much broth? Thicken with a potato or add a splash of cream.
- OVER-TORCHED the garlic? Start over or add a squeeze of lemon to brighten.
- SCOURED the soup? Use a fine sieve to strain and smooth it out again.
Fast fixes for common issues.
- When the soup is too thick, splash in hot water or broth and blend again.
- When bland, add a pinch of salt or a squeeze of citrus.
- Splash a little vinegar or lemon juice to brighten.
- Patch over burnt flavor by adding fresh herbs or a drizzle of good olive oil.
- Shield from overcooking by removing from heat once smooth and heated through.
Make-ahead and storage tips for flavors and convenience.
- Roast the vegetables and store in the fridge for up to 2 days before blending.
- Soup can be made a day ahead; reheat gently on the stove, stirring occasionally.
- Flavor deepens overnight, making the soup richer and more integrated.
- Store in airtight containers for up to 3 days in the fridge or freeze for 1 month.
