There’s something about roasting sweet potatoes and carrots until they’re deeply caramelized that makes this soup feel like a warm hug in a bowl. I love how the smoky, slightly charred edges bring out their natural sweetness, transforming simple ingredients into something unexpectedly complex. It’s a dish that feels both humble and special, perfect for those cozy evenings when you want comfort but also a bit of surprise.
I started playing with this recipe after a trip to a smoky mountain village where everything was roasted over open flames. The depth of flavor from that method stuck with me, and I realized I could recreate that at home with my oven. Now, every fall, I make a batch—filling my kitchen with the smell of caramelized sugar, toasted earth, and a hint of wood smoke—feeling a little nostalgic for simpler, slower days.

Ingredient breakdown: key components
- Sweet potato: I love their creamy texture and natural sweetness, but if you’re short on time, swap with butternut squash for a milder, nuttier flavor.
- Carrots: Their bright, earthy sweetness brightens the soup—try parsnips for a similar sweetness with a slightly spicier edge.
- Olive oil: I use a good drizzle for roasting—if you prefer a richer taste, swap with melted butter or coconut oil for a deeper, nutty aroma.
- Smoked paprika: Adds that smoky depth I crave—if you don’t have it, a pinch of chipotle powder gives a similar punch, but use less to avoid overpowering.
- Coconut milk: I love its creamy, slightly sweet finish—sub with heavy cream for richness, or for dairy-free, try almond milk for a lighter lift.
- Onion: It’s the backbone of flavor, sautéed until golden—if you’re out, shallots or leeks also work, adding their unique subtle sweetness.
- Salt & pepper: Essential for balancing and enhancing all those natural flavors—don’t skimp, but be cautious with salt if using broth with added sodium.

Step-by-step guide to sweet potato carrot soup
- Preheat your oven to 220°C (430°F). Line a baking sheet with parchment paper to prevent sticking.

Prep, store, and reheat tips
- Peel and chop sweet potatoes and carrots a day in advance; store in airtight container in the fridge for up to 24 hours. The smell of fresh, earthy roots makes the kitchen feel cozy even before cooking begins.
- Roast the vegetables ahead of time; once cooled, keep in an airtight container in the fridge for up to 2 days. Reheat in a warm oven or microwave, noticing the caramelized aroma intensify with each reheat.
