Ingredients for Roasted Sweet Potato Soup

Sweet potato: The star ingredient! Roasting caramelizes its natural sweetness, making the soup rich and velvety.  

Olive oil: For sautéing and adding richness. Swap with avocado or coconut oil if needed.

Yellow onion: Builds a savory base. Red onion or shallots work too.

Garlic: Adds warmth and depth. Not a garlic fan? Use just one clove or swap it for a pinch of garlic powder for a milder touch.

Full-fat coconut milk: Makes the soup ultra-creamy with a subtle sweetness. Use light coconut milk for a thinner version.

Vegetable broth: Helps blend everything. Swap with chicken broth or even water (just adjust seasoning).

Fresh ginger: Adds a zesty kick to balance the sweetness. No fresh ginger? Use ground, but fresh is best!

Yellow curry powder: Brings warmth and subtle spice. No curry powder? Try a mix of cumin, coriander, and a pinch of cinnamon.

Spices: Turmeric for color, sage for earthiness, red pepper for heat, and salt to enhance all the flavors. Swap sage with thyme, and red pepper with smoked paprika for a milder kick!

For serving:

Cooked quinoa: Adds protein and texture. Swap with brown rice.

Fresh cilantro: Brightens the flavors. Not a fan? Use parsley or green onions.

Plain yogurt or sour cream: Optional, for a creamy finishing touch. Use coconut yogurt for a dairy-free option.

Drizzle of oil: Olive oil, chili oil for spice, or toasted sesame oil for extra richness.

How to Make Roasted Sweet Potato Soup

Start by roasting the sweet potato. Poke a few holes in it with a fork, wrap it in foil, and pop it in a 400°F oven for about an hour. 

Roasting brings out its natural sweetness and makes blending a breeze. Once it’s fork-tender, let it cool a bit before handling.

While the sweet potato cools, sauté the onion in olive oil until translucent, then add the garlic, ginger, and spices, letting them bloom for extra flavor.

Scoop the sweet potato flesh into a blender (leave the skin on for extra fiber if you want) and add the sautéed mixture, vegetable broth, and coconut milk. Blend until smooth and creamy. If it’s too thick, add more broth to reach your desired consistency.

Pour the soup back into a pot and warm it up to your liking. Serve with a scoop of quinoa, fresh cilantro, and a swirl of yogurt if you like things extra creamy.

That’s it! Cozy, creamy, and packed with flavor – this soup is about to become your new favorite.

Frequently Asked Questions

Can I make this soup ahead of time?

Absolutely! It stores well in the fridge for up to 4 days and tastes even better as the flavors meld. Reheat on the stovetop or in the microwave.

How do I make this soup without a blender?

Use a potato masher or an immersion blender for a chunkier texture. You can also finely mash the sweet potatoes with a fork and whisk everything together.

Can I freeze it?

Yes! Let it cool completely, then store it in an airtight container in the freezer for up to 3 months. Thaw overnight in the fridge before reheating. 

How can I make it thicker/thinner?

To thicken, simmer it longer or stir in a spoonful of mashed sweet potato. To thin it out, add more water, broth or coconut milk until it reaches your desired consistency.

Can I make this without coconut milk?

Yep! Try cashew cream, or oat cream for a different kind of creaminess. Just keep in mind that lighter options may result in a thinner soup.

Recipe Adaptations & Additions

• Make it extra creamy – Stir in cashew cream, oat milk, or a splash of heavy cream for an ultra-smooth texture.
• Boost the protein – Add tofu, chickpeas, or blend in white beans for a heartier meal.
• Make it spicier – Extra red pepper flakes, sriracha, or a dash of cayenne will turn up the heat.
• Give it a Thai twist – Swap curry powder for Thai red curry paste and stir in peanut butter for a rich, nutty flavor.
• Turn it into a stew – Leave it chunky and add chickpeas, carrots, or kale for more texture.
• Brighten it up – A squeeze of lime or lemon at the end makes the flavors pop.
