What You’ll Need to Make This Soup

  • Sweet Potatoes: The star of the dish, providing natural sweetness, a creamy base, and a dose of vitamin A.
  • Carrots: Add subtle sweetness and an earthy undertone, while enhancing the orange hue.
  • Red Onion: Brings mild sharpness and depth to balance the sweetness.
  • Garlic: Adds savory complexity and enhances the overall flavor.
  • Vegetable Broth: Forms the flavorful liquid base and ties all ingredients together.
  • Olive Oil: Used for roasting, adds richness and helps the vegetables caramelize.
  • Fresh Thyme: Infuses herbal notes that complement the root vegetables beautifully.
  • Ground Cumin: Offers warm, earthy spice that balances sweetness with depth.
  • Salt & Pepper: Essential for enhancing and balancing flavors.

Ingredient Swaps and Substitutions

  • White or Yellow Onion: Can be used in place of red onion for a slightly milder flavor.
  • Butternut Squash: A great substitute or addition to sweet potatoes for a different texture and sweetness.
  • Coconut Milk: Add for extra creaminess and a hint of tropical flavor; works well with the roasted profile.
  • Dried Herbs: If fresh thyme isn’t available, dried thyme or Italian seasoning can be used instead.
  • Spicy Kick: Add cayenne or smoked paprika if you prefer a spicier version of this roasted sweet potato soup.

How to Make Roasted Sweet Potato Soup

  1. Preheat the oven to 400°F (200°C). Line a large baking sheet with parchment paper.
  2. Chop the vegetables: Cut sweet potatoes, carrots, and red onion into chunks. Place them on the baking sheet along with peeled garlic cloves.
  3. Season and roast: Drizzle olive oil over the veggies. Sprinkle with salt, pepper, cumin, and thyme. Toss to coat evenly. Roast for 35–40 minutes until vegetables are tender and slightly caramelized.
  4. Blend the soup: Transfer the roasted vegetables to a blender or use an immersion blender in a large pot. Add vegetable broth gradually and blend until smooth. Adjust consistency by adding more broth if needed.
  5. Simmer and adjust seasoning: Pour the soup into a large pot and bring to a gentle simmer over medium heat. Taste and adjust salt, pepper, or cumin to your liking.
  6. Serve warm: Ladle into bowls and top with fresh thyme, a swirl of coconut cream, or toasted pumpkin seeds for crunch.

Expert Tips for the Best Flavor and Texture

  • Roast evenly: Spread veggies in a single layer for even caramelization. Crowded pans steam instead of roast.
  • Use hot broth: This keeps the soup warm and helps it blend more smoothly.
  • Blend in batches: If using a blender, work in small portions to prevent overflow and ensure creaminess.
  • Don’t skip the garlic: Roasted garlic gives a rich, mellow depth that makes the soup shine.
  • Storage: Keep leftovers in an airtight container in the fridge for up to 4 days. Freeze for up to 3 months.

Delicious Pairings and Fun Variations

  • Crusty Bread: A classic companion — sourdough or multigrain works best for texture contrast.
  • Grilled Cheese Sandwich: A comforting combo that turns soup into a full meal.
  • Toasted Nuts or Seeds: Pumpkin seeds or chopped pecans add crunch and protein.
  • Spiced Version: Add curry powder, ginger, or turmeric for a globally inspired variation.
  • Creamy Upgrade: Stir in coconut milk, oat cream, or cashew cream just before serving for extra richness.
  • Make Ahead: This roasted sweet potato soup tastes even better the next day as the flavors deepen. Make a big batch and reheat as needed.
