Ingredients You’ll Need
Nothing complicated here—just simple, wholesome ingredients that work in harmony to create a soup that’s creamy, flavorful, and satisfying. Each item plays a crucial role: from the sweetness of the onion to the savory depth of Parmesan and the subtle heat from spices.
- Sweet onion: Finely chopped to add natural sweetness and a cozy base flavor.

- Garlic cloves: Crushed to release aromatic magic that elevates the whole soup.
- Butter or vegan butter: Adds richness and silky mouthfeel.
- Broth (chicken or vegetable): Creates a flavorful, savory base that ties everything together.
- Raw cashews: Blend seamlessly for extraordinary creaminess without dairy overload.
- Salt: Essential for balancing and enhancing all the flavors.
- Red pepper flakes: Just a pinch for a gentle kick and warmth.
- Paprika: Adds a subtle smoky note and lovely color.
- Dried sage: An earthy herbal touch that complements cauliflower beautifully.
- Parmesan cheese: The final flourish delivering sharp, nutty richness—swap with dairy-free cheese if preferred.
How to Make Creamy Cauliflower Soup with Cashews and Parmesan Recipe
Step 1: Sauté Onion and Olive Oil
Start by warming olive oil in a Dutch oven or large pot over medium heat. Add the finely chopped sweet onion and let it gently soften and release its natural sweetness for about 5 minutes. This simple step lays down a flavorful foundation that makes all the difference in the final soup.
Step 2: Add Cauliflower and Garlic
Next, toss in the cauliflower florets, continuing to sauté for another 5 minutes. This allows the edges to caramelize slightly, adding depth. Then add the crushed garlic, stirring it through for just 1 minute until fragrant—this quick burst of garlic aroma wakes up all the taste buds.
Step 3: Add Broth and Seasonings, Boil
Pour in the broth along with butter, raw cashews, salt, red pepper flakes, paprika, and dried sage. Bring everything to a vigorous boil, then reduce the heat slightly while maintaining that rolling boil for 20 minutes. This step softens the cauliflower and cashews perfectly, so they’ll blend into a silky soup later.
Step 4: Blend Until Smooth
Turn off the heat and stir in the grated Parmesan cheese. Now the magic happens—use a high-speed blender or an immersion blender right in the pot to puree everything until ultra creamy and smooth. The cashews lend a luscious, velvety texture that feels indulgent without heaviness.
Step 5: Serve and Enjoy
Ladle your soup into bowls and prepare for a little celebration. The Creamy Cauliflower Soup with Cashews and Parmesan Recipe is ready to wow you and anyone lucky enough to share it. Garnish and serve for maximum flavor and appeal.
How to Serve Creamy Cauliflower Soup with Cashews and Parmesan Recipe
Garnishes
Brighten each bowl with a sprinkle of fresh parsley and an extra shaving or two of Parmesan cheese for that salty punch. For a bit of crunch and elegance, add Parmesan cheese whisps or some toasted baguette slices. These little touches make every spoonful feel extra special.
Side Dishes
This soup pairs beautifully with crisp green salads or roasted vegetables. A crusty bread or garlic toast complements the creamy texture perfectly, helping to soak up every last drop. For a heartier meal, serve alongside a simple grilled chicken or your favorite plant-based protein.
Creative Ways to Present
For a fun twist, serve the soup inside hollowed-out mini sourdough loaves, turning dinner into an experience. You can also drizzle some chili oil or a swirl of cream on top for visual appeal and a flavor boost. Hosting guests? Serve the soup in small cups as a sophisticated appetizer.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer your soup to an airtight container and store it in the refrigerator for up to 3 days. The flavors actually deepen over time, so leftovers taste incredible the next day.
Freezing
This Creamy Cauliflower Soup with Cashews and Parmesan Recipe freezes very well. Pour into freezer-safe containers or bags, leaving a bit of headspace for expansion. Freeze for up to 3 months and thaw overnight in the fridge before reheating.
Reheating
Reheat gently on the stovetop over low heat, stirring occasionally to maintain that irresistible creamy texture. If the soup thickens too much during storage, simply add a splash of broth or water to loosen it up without losing any flavor.
FAQs
Can I make this soup vegan?
Absolutely! Just swap the butter for a vegan butter and use a dairy-free Parmesan alternative or nutritional yeast. The cashews provide plenty of creaminess, so it’s wonderfully adaptable.
What if I don’t have raw cashews?
You can substitute with soaked almonds or even cashew butter, but raw cashews work best for that smooth, creamy texture that’s signature to this recipe.
Is this soup gluten-free?
Yes, the Creamy Cauliflower Soup with Cashews and Parmesan Recipe is naturally gluten-free. Just make sure your broth and cheese alternatives (if using) are certified gluten-free to be safe.
Can I make this soup in a slow cooker?
While possible, sautéing the onions and garlic first really enhances flavor. You can sauté, then transfer everything to a slow cooker and cook until tender before blending.
How spicy is the soup?
The red pepper flakes add just a gentle warmth, not overwhelming heat. You can adjust the amount to suit your taste or omit if you prefer a milder soup.
