How to Make Creamy Cauliflower White Bean Soup with Roasted Parmesan Cauliflower Croutons Recipe
Step 1: Prepare the Vegetables and Sauté
Start by chopping your cauliflower into bite-sized florets and reserving about one cup for the roasted croutons. Don’t toss those stems—they’re full of flavor and help give the soup a wonderful texture. Heat your olive oil over medium heat in a pot, then toss in chopped onion, celery, and grated carrot. Sauté until everything is tender and fragrant, about five minutes. This step builds the flavorful base for your soup.
Step 2: Add Cauliflower, Garlic, and Beans
Stir in the cauliflower florets and smashed garlic, coating them in that savory mixture. Then, add the rinsed white beans, vegetable broth, fresh thyme, and the chunk of Parmesan cheese. Bring everything to a gentle simmer—the cozy moment where flavors begin harmonizing.
Step 3: Simmer Until Tender
Reduce the heat to low and let the soup simmer for 15 to 18 minutes. You’ll know it’s ready when the cauliflower becomes soft and all the flavors have mingled beautifully. This slow cooking also allows the Parmesan cheese wedge to infuse the broth with its signature umami.
Step 4: Blend to Creamy Perfection
Remove the Parmesan chunk, then use an immersion blender to purée the soup until silky smooth. If you don’t have one, carefully cool slightly and blend in batches in a stand blender. The white beans and cauliflower create an incredibly creamy texture that feels indulgent without any cream added.
Step 5: Roast the Parmesan Cauliflower Croutons
While the soup is simmering, preheat your oven to 450 degrees. Place the reserved cauliflower florets in an olive oil–coated baking dish. Drizzle with extra-virgin olive oil and toss to coat evenly. Roast for 15 to 20 minutes, stirring halfway, until tender and golden. Sprinkle with finely grated Parmesan, then broil for 3 to 5 minutes until beautifully crisp and browned. These croutons add a stunning contrast of texture and intense cheesy flavor that will have you sneaking tastes before serving.
Step 6: Season and Serve
Season the soup with salt and freshly ground black pepper to your liking, then ladle into bowls. Top generously with the roasted Parmesan cauliflower croutons and a sprinkle of chopped parsley for a fresh pop of color and flavor.

Garnishes
This soup shines with its roasted Parmesan cauliflower croutons, which provide a lovely textural counterpoint.

Creative Ways to Present
Serve in rustic bowls with a swirl of creamy yogurt or a sprinkle of chili flakes for a spicy kick. You can also add a few toasted pine nuts or chopped chives on top for added crunch and flavor complexity. For a stunning presentation, ladle the soup into edible bread bowls and nestle the Parmesan cauliflower croutons right inside.
Make Ahead and Storage
Storing Leftovers
Cool the soup completely before transferring it to airtight containers. It will keep in the fridge for up to four days, maintaining its creamy texture and vibrant flavor. Store the roasted Parmesan cauliflower croutons separately to avoid sogginess.
Freezing
This Creamy Cauliflower White Bean Soup with Roasted Parmesan Cauliflower Croutons Recipe freezes beautifully. Pour the cooled soup into freezer-safe containers, leaving some room for expansion, and freeze for up to three months. Freeze croutons separately in a sealed bag and add freshly roasted ones when ready to serve for the best texture.
Reheating
Reheat gently on the stove over low heat, stirring often to prevent sticking. If the soup thickens too much, add a splash of broth or water to loosen it up. Avoid microwaving croutons to keep their crispiness—roast a fresh batch or warm in the oven as needed.
FAQs
Can I use other types of beans instead of cannellini?
Absolutely! Great northern or navy beans work just as well and provide that creamy texture. Just be sure to rinse canned beans well to reduce sodium.
Is this soup vegan?
In its original form, the Parmesan cheese makes it non-vegan. However, you can substitute with a vegan Parmesan alternative and use vegetable broth to keep it completely plant-based.
Can I make the soup in a slow cooker?
Yes! Simply sauté the vegetables first, then add everything except the Parmesan wedge to the slow cooker and cook on low for 4 to 6 hours. Add the Parmesan near the end to infuse flavor, then blend before serving.
How crispy are the roasted Parmesan cauliflower croutons?
They become delightfully crisp on the outside thanks to the broiling step, while remaining tender inside, which adds a wonderful contrast to the creamy soup base.
What can I serve with this soup for a heartier meal?
This soup pairs wonderfully with a grilled cheese sandwich, roasted chicken, or a robust vegetable tart to round out the meal while keeping things balanced and flavorful.

Instructions
- Prepare the cauliflower: Chop the cauliflower into bite-sized florets and stems, discarding any tough parts. Reserve about 1 cup of florets for roasting as garnish.
- Sauté the vegetables: Heat 2 tablespoons of olive oil in a medium pot over medium heat. Add the chopped onion, celery, and grated carrot. Sauté for about 5 minutes until softened and fragrant.

- Simmer the soup: Reduce the heat to low and let the soup simmer gently for 15 to 18 minutes, or until the cauliflower is very soft.
