How to Make Sweet Potato Soup with Roasted Cauliflower Crumbles (Step-by-Step)
This simple soup recipe is a joy to make and enjoy. Follow these steps to create the perfect dish.
Step 1: Prep the Cauliflower
Preheat your oven to 425°F (220°C). Toss the cauliflower florets with olive oil, salt, and pepper in a mixing bowl. Spread them on a baking sheet in a single layer. Roast for about 25-30 minutes or until golden and crispy, stirring halfway through. The nutty aroma of the roasting cauliflower will fill your kitchen, and the lemon zest added at the end gives it a bright finish.
Step 2: Cook the Base
In a large pot or Dutch oven, heat 2 tablespoons of olive oil over medium heat. Add the diced onion, stirring occasionally until translucent, about 5 minutes. The sweetness of the onion as it cooks adds depth to the soup. Next, add the minced garlic and sauté for another 1-2 minutes until fragrant, being careful not to brown it.
Step 3: Add Sweet Potatoes and Spices
Add the cubed sweet potatoes, ground cumin, and coriander to the pot. Stir to combine, letting the spices toast slightly for a minute or two until fragrant. Pour in the vegetable broth, and bring the mixture to a simmer. Cover and cook until the sweet potatoes are tender, about 15-20 minutes.
Step 4: Blend the Soup
Once the sweet potatoes are tender, remove the pot from heat. Use an immersion blender to puree the soup until smooth. If you don’t have an immersion blender, you can carefully transfer the soup in batches to a countertop blender.
Step 5: Add Coconut Milk
Stir in the coconut milk, and season with salt and black pepper to taste. Return the pot to low heat to warm through, whisking until the mixture is creamy and homogenous. The rich, creamy texture of the coconut milk should make it glossy and luscious.
Step 6: Serve and Garnish
Ladle the soup into bowls and top with the crispy roasted cauliflower crumbles. You may also wish to drizzle a little extra coconut milk or olive oil for added richness.

Common Mistakes to Avoid
- Avoid overcooking the garlic; it should be fragrant, not burnt.
- Don’t skip the roasting of the cauliflower; it adds essential flavor and texture.
- Be cautious with salt when adding it after blending; taste first to avoid over-salting.
Tips and Tricks for Success
- For an extra layer of flavor, consider adding a dash of smoked paprika or cayenne pepper for a touch of heat.
- Pair the soup with crusty bread or a light salad for a complete meal.
- This soup freezes beautifully; store it in airtight containers for up to three months.
Variations
- Try using butternut squash instead of sweet potatoes for a different flavor profile.
- Substitute coconut milk with almond milk for a lighter version.
- Incorporate different spices like nutmeg or cinnamon for a seasonal twist.
How to Serve
