Ingredients You’ll Need
These ingredients are wonderfully simple yet essential to building layers of flavor and texture in the soup. Each one plays a key role, from the sweet earthiness of the sweet potatoes to the nutty crunch of the roasted cauliflower crumbles.

- Macadamia nuts or cashews: Used for blending, these nuts create a luxuriously smooth texture and mild nutty undertone.
- Cauliflower florets: Roasted and crumbled for a delightful crunchy contrast on top.

How to Make Sweet Potato Soup with Roasted Cauliflower Crumbles Recipe
Step 1: Preheat the Oven
Start by heating your oven to 425 degrees. This high temperature ensures that the vegetables roast beautifully, developing caramelized edges that add deep flavor to the soup. A hot oven is critical for that perfect golden color and tender texture.
Step 2: Roast the Sweet Potatoes and Onions
On a baking sheet, spread out the sweet potato chunks and red onion slices. Drizzle them generously with avocado or olive oil and sprinkle with kosher salt. Roast for 30 to 45 minutes until they’re soft inside and have those gorgeous golden brown edges that bring out their natural sweetness.
Step 3: Roast the Cauliflower
While your sweet potatoes and onions are roasting, toss the cauliflower florets in one tablespoon of oil and one teaspoon of salt, then spread them out on a separate baking sheet. Roast the cauliflower for about 30 minutes, preferably tucking it on a rack beneath the other veggies so it picks up lovely oven flavors without overcrowding.
Step 4: Crumble and Brown the Cauliflower
Once roasted, use the back of a wooden spoon or spatula to gently break the cauliflower into smaller crumbles. Return these to the oven for another 10 to 15 minutes to get them extra crispy and browned, adding a fantastic texture contrast to the smooth soup.
Step 5: Blend the Soup
Let the roasted sweet potatoes and onions cool a little, then blend them in batches with the warm vegetable broth, fresh ginger knob, and macadamia nuts or cashews. Pulse the blend until ultra-smooth, velvety, and utterly inviting. This step transforms the roasted vegetables into a comforting, silky soup with just the right density.
Step 6: Season and Assemble
Taste the blended soup and adjust seasoning with more salt as needed. Ladle it into bowls, then generously sprinkle the roasted cauliflower crumbles on top for that irresistible crunch. Finish the look and flavor with a sprinkle of chopped chives, a drizzle of your favorite infused oil (like spicy chili oil), and a squeeze of fresh lemon juice for a bright, lively finish.
How to Serve Sweet Potato Soup with Roasted Cauliflower Crumbles Recipe
Garnishes
To elevate this soup visually and flavor-wise, don’t skip on the garnishes! The roasted cauliflower crumbles bring a smoky crunch, fresh chives add a splash of color and mild sharpness, while a swirl of infused oil lends that tantalizing spicy complexity. Lastly, a kiss of lemon juice instantly brightens each spoonful.
Side Dishes
This soup pairs beautifully with rustic bread, crunchy crackers, or a simple mixed green salad dressed in lemon vinaigrette. It can be a hearty standalone meal or a stunning starter for a more extensive dinner — either way, it always feels special.
Creative Ways to Present
Serve this soup in warm, rustic bowls or pumpkin-shaped soup dishes to amplify its cozy, seasonal vibe. For gatherings, offer a toppings bar with extra chives, nuts, and infused oils, letting guests customize their bowls to their taste. Adding a dollop of Greek yogurt or crème fraîche can also add a lovely cooling creaminess.
Make Ahead and Storage
Storing Leftovers
Store any leftover soup in an airtight container in the refrigerator for up to 4 days. Keep the roasted cauliflower crumbles separate to maintain their crunchy texture, adding them just before serving again.
Freezing
This sweet potato soup freezes beautifully! Pour the cooled soup into freezer-safe containers, leaving space for expansion. Freeze for up to 3 months. Since cauliflower crumbles can become mushy when frozen, freeze them separately or make fresh ones when ready to serve.
Reheating
Reheat the soup gently over medium-low heat on the stove, stirring occasionally until warmed through. Add a splash of vegetable broth or water if it has thickened too much. Reintroduce the crispy cauliflower crumbles after reheating to preserve their delightful texture.
FAQs
Can I use other nuts instead of macadamia nuts or cashews?
Absolutely! Almonds or walnuts can work, but keep in mind they may slightly alter the texture and flavor. Cashews and macadamia nuts offer the creamiest blend, which complements the soup perfectly.
Is this soup vegan-friendly?
Yes, it’s entirely vegan. Using vegetable broth and nuts for creaminess, this recipe contains no animal products, making it suitable for vegan and plant-based diets.
Can I use frozen cauliflower for the crumbles?
While fresh cauliflower is best for roasting and crisping up nicely, you can use frozen florets if fresh aren’t available. Just be sure to pat them dry thoroughly before roasting to avoid sogginess.
What can I substitute if I don’t have avocado oil?
Olive oil is a perfect substitute and works just as well to roast the vegetables, bringing its own lovely flavor that complements the soup.
Can I make this soup in a slow cooker?
You can roast the vegetables first to develop flavor and then add them with broth, ginger, and nuts to a slow cooker. Cook on low for 4-6 hours before blending. However, roasting first is key for that rich roasted flavor.
Final Thoughts
There’s something truly magical about this Sweet Potato Soup with Roasted Cauliflower Crumbles Recipe that feels like a warm hug in a bowl.
