Cauliflower: Choose a medium head with tight florets and no brown spots for the best roast and flavor.
Yellow onion: Sliced thin, it caramelizes lightly during roasting and adds gentle sweetness.
Garlic: Using whole cloves to roast means mellow, buttery garlic that melts into the soup.
Avocado oil: Its high smoke point is perfect for roasting without burning.
Sea salt & black pepper: Essential for seasoning; adding bit by bit lets you control the flavor.
Raw cashews: Soaked to soften, they create that rich, creamy body once blended.
White beans (Cannellini or similar): They boost protein and help thicken the soup naturally.
Vegetable broth: Use a good quality one, or homemade if possible, for depth of flavor.
Water: To adjust the consistency without diluting taste.
Ground nutmeg: Just a hint adds warmth and subtle earthiness.
Lemon juice: Brightens the final soup, balancing the creamy richness.
Parsley, red pepper flakes, pine nuts, olive oil (for garnish): These optional toppings add freshness, heat, crunch, and extra flavor.

How to Make Creamy Roasted Cauliflower Soup Recipe

Step 1: Roast those gorgeous veggies

Preheat your oven to 400°F (204°C). Line a baking sheet with parchment paper to prevent any sticking or mess. Now, spread the cauliflower florets, sliced onion, and whole garlic cloves evenly on the sheet. Drizzle with avocado oil, sprinkle with sea salt and pepper, then toss everything until every piece is well coated. This roasting step is crucial — it caramelizes the veggies, which gives the soup a deeply satisfying flavor. Pop the tray into the oven and roast for about 30 minutes, stirring halfway through so everything browns nicely. You’ll want those edges to get golden and a bit crispy, trust me.

Step 2: Prep your cashews and beans

While your veggies roast, place the cashews in a bowl or measuring cup and cover them with boiling water to soften them. I usually set a timer for about 20-30 minutes — this soaking step is key for blending your soup into a dreamy silky texture. Meanwhile, rinse and drain your can of white beans so they’re ready to go when the cauliflower is done.

Step 3: Combine and simmer

Once the cauliflower, onion, and garlic come out of the oven, immediately transfer them to your stockpot or Dutch oven to keep the heat in. Don’t skip reserving a few florets for optional garnish — it adds a nice texture contrast and looks lovely. Add the rinsed beans, vegetable broth, water, and the tiny pinch of ground nutmeg to the pot. Give everything a good stir and bring it to a vigorous simmer over medium-high heat. Once bubbling, reduce heat to medium-low and let it simmer gently for 15-20 minutes. At this point, the cauliflower should be so soft it nearly falls apart with a fork — that’s when you know it’s perfect for blending.

Step 4: Blend to silky perfection

Turn off the heat and carefully transfer the hot mixture to your high-speed blender (make sure it’s safe for hot liquids to avoid accidents). Add the lemon juice and a pinch of salt, then blend until the texture is smooth and creamy. Pour about half the soup back into the pot. Drain the cashews and add them to the remaining soup in the blender. Blend that mixture until it’s pale, creamy, and velvety — this is what makes the soup taste indulgent. Pour the cashew blend back into the pot and stir gently to swirl the textures together. Give it a quick taste and adjust seasoning with salt, pepper, or more nutmeg if you want a nuttier note.

Step 5: Garnish and serve with love

Pour the soup into your favorite bowls and get creative with garnishes. I love using some of the reserved cauliflower florets, a sprinkle of fresh parsley, a dash of red pepper flakes for gentle heat, a handful of toasted pine nuts for crunch, and a swirl of good quality olive oil. It seriously turns this simple soup into a restaurant-worthy experience you’ll enjoy every time.

Pro Tips for Making Creamy Roasted Cauliflower Soup Recipe

Even Roasting: Make sure to stir the veggies halfway through roasting so that each piece gets those delicious golden spots, which adds a nice depth of flavor.
Cashew Soak Time: Don’t skip soaking your cashews — it’s a game changer for smooth blending and creamy texture that feels indulgent.
Blend in Two Stages: Blending part of the soup with cashews separately gives you the perfect balance of creaminess without overpowering the roasted cauliflower flavor.
Season Gradually: I taste as I go, adding salt and nutmeg slowly to keep the flavor just right and well balanced.

Garnishes

I personally love topping this soup with fresh parsley for brightness and a handful of toasted pine nuts for crunch—that combo adds a welcome contrast. A drizzle of extra virgin olive oil not only adds richness but also a luxurious finishing touch. When I’m feeling adventurous, red pepper flakes give just the right hint of warmth and spice, especially on chilly days.

Side Dishes

My go-to sides are crusty artisan bread or garlic naan to sop up every creamy drop. For a lighter meal, a crisp green salad dressed with lemon vinaigrette complements the soup nicely. Sometimes I pair it with warm roasted sweet potatoes or a simple baked potato for added heartiness.

Creative Ways to Present

For special dinners, I love serving this soup in mini pumpkin bowls or rustic bread bowls — it makes an instant impression. Swirling a vibrant pesto or beet puree on top also adds a colorful, gourmet flair that guests always ask about. Toasted sesame seeds or crispy shallots can boost both flavor and texture if you want to surprise your family with a fun twist.

Make Ahead and Storage

Storing Leftovers

I usually store this soup in airtight containers in the fridge, and it keeps beautifully for up to a week. The flavors mellow and deepen overnight, so leftovers taste even better the next day. Just give it a good stir before reheating.

Freezing

I’ve had great success freezing this soup in portioned containers or freezer bags for up to a month. Just thaw overnight in the fridge and give it a quick warm-up on the stove with a splash of broth or dairy-free milk to loosen it up if it thickens too much.

Reheating

I always reheat this soup gently on the stovetop, stirring often. If it feels a bit too thick, I add a little vegetable broth or unsweetened plant milk to return it to that delicious creamy consistency you loved the first time.

FAQs

Can I make Creamy Roasted Cauliflower Soup Recipe without cashews?

Absolutely! Cashews add a lovely creamy texture, but if you’re allergic or don’t have any, you can substitute with a can of full-fat coconut milk or omit them entirely and use extra white beans for creaminess. The soup will still be delicious, just slightly different in texture.
Is this soup suitable for meal prep?

Yes! This cream soup holds up well in the fridge and freezer, making it a fantastic option for meal prep. Portion it out in containers and enjoy easy, nutritious lunches or dinners all week long.
How can I make this soup spicier?

Adding red pepper flakes, cayenne pepper, or a few dashes of hot sauce during blending or right before serving will bring some heat. I recommend starting with a small amount and tasting as you go to avoid overpowering the natural flavors.
Can I use fresh herbs in this soup?

Definitely! Fresh parsley, thyme, or rosemary roasted with the cauliflower, or stirred in at the end, adds wonderful aroma and taste. Just be mindful not to overpower the soup’s delicate flavors.
