Smart Swaps and Substitutions

- Looking for more protein? Add a scoop of cooked red lentils before blending.

How to Make Roasted Sweet Potato Soup from Scratch
This soup is made by roasting the vegetables first, then blending everything into a silky, nourishing bowl of goodness.
- Preheat your oven to 400°F (200°C). Line a baking tray with parchment paper.
- Prepare the vegetables. Peel and cube the sweet potatoes, peel and roughly chop the red onion, and leave the garlic cloves unpeeled.
- Roast the vegetables. Spread the sweet potato cubes, onion, and garlic cloves on the baking sheet. Drizzle with olive oil and sprinkle with cinnamon, nutmeg, salt, and pepper. Roast for 30–35 minutes until golden and tender.
- Cool and peel. Let the roasted garlic cool slightly, then squeeze the softened garlic out of the skins.
- Blend the soup. Transfer all the roasted vegetables into a blender or soup pot. Add vegetable stock and blend until smooth. If you’re using a pot, use an immersion blender for ease.
- Heat and serve. Pour the blended soup into a large saucepan and warm over medium heat. Adjust salt, pepper, or spices as needed. Serve hot, optionally topped with seeds, herbs, or a swirl of non-dairy cream.
Tricks to Make It Perfect Every Time
Creating a flawless roasted sweet potato soup is easy, but here are a few expert tips to take it to the next level:
- Cut sweet potatoes evenly so they roast at the same rate.
- Don’t skip roasting – it’s the key to deep flavor.
- Blend in stages if you’re using a small blender to avoid spills.
- Add liquid gradually if you prefer a thicker or thinner consistency.
- Taste as you go – adjust spices to suit your preference.
For leftovers, store in an airtight container in the fridge for up to 4 days, or freeze for up to 3 months. Reheat on the stove or microwave, adding a splash of water or broth if it thickens too much.
Delicious Pairings and Fun Variations
Roasted sweet potato soup is satisfying on its own but can be elevated with the right sides and toppings:
- Serve with: Crusty sourdough, a fresh salad, or a vegan grilled cheese.
- Top with: Toasted pumpkin seeds, coconut cream, chopped chives, or a sprinkle of chili flakes for heat.
- Make it spicy: Add cayenne or harissa before blending.
- Make it creamy: Stir in coconut milk or cashew cream before reheating.
- For meal prep: Portion into jars for easy grab-and-go lunches.

Frequently Asked Questions About Roasted Sweet Potato Soup
Can I use boiled sweet potatoes instead of roasting them?
While you can use boiled sweet potatoes in a pinch, roasting them adds a deeper, more complex flavor due to caramelization. If you’re short on time, roasting is worth the extra effort for the best version of roasted sweet potato soup.
How do I make this soup thicker or thinner?
To thicken the soup, reduce the amount of vegetable stock or add a handful of cooked red lentils before blending. For a thinner consistency, simply add more vegetable broth or even water until the soup reaches your desired texture.
Is roasted sweet potato soup good for freezing?
Absolutely. This soup freezes beautifully. Let it cool completely, portion it into airtight containers, and store it in the freezer for up to 3 months. Reheat gently on the stove and stir well to restore its creamy texture.
