The Best Roasted Cauliflower Soup Recipe

Cauliflower is one of the most versatile vegetables on the market! Whether you’re making honey garlic baked cauliflower or roasted red pepper and cauliflower soup, it takes on the flavor of whatever it’s paired with fabulously. 

So, we knew we had to pair it with some of our favorite warm, Middle Eastern spices, and what better way to do that than in homemade soup? 

With minimal prep time and a quick cook time, this recipe turns out smooth and velvety in texture with a savory, slightly spicy taste that will make your tastebuds sing. Topped with a dash of heavy cream, crisp croutons, and zesty za’atar seasoning, it’s unlike anything you’ve ever tasted before and will leave you coming back again and again for more!

Ingredients for Easy Cauliflower Soup

  • Aromatics – Whole garlic cloves and shallots form the base of the soup, creating a pungent taste that’s savory and slightly sweet.  
  • Cauliflower – Use a whole head of cauliflower, and chop it yourself. Or, save time, and opt for pre-chopped cauliflower florets. 
  • Bone Broth – We recommend using chicken or turkey bone broth to add tons of flavor and nutrients to this recipe. Beef bone broth will also work, but the flavor will be slightly different. 
  • Seasonings – Salt, black pepper, oregano, smoked paprika, and cumin create the savory, slightly spicy flavor we’re looking to achieve. 
  • Olive Oil – This helps caramelize the veggies, enhancing their natural flavor and creating a subtle sweetness. 
  • Heavy Cream – A small splash helps create a creamy, velvety consistency and enhances the rich flavor. 

Ways to Customize

Feel free to experiment with different flavor combinations to suit your preferences! Some of our favorite ways to customize this soup include: 

  • Adding veggies Include carrots or celery when you cook the onion. Or, stir in kale or spinach at the end of cooking for even more fiber nutrients. 
  • Including protein – Add cooked sausage, beef, turkey, shredded chicken, or even crumbled turkey bacon for a boost of protein. 
  • Making it cheesy – Stir in freshly shredded cheddar, mozzarella, or parmesan cheese for extra depth. 
  • Amping up the spice – Include a splash of hot sauce or a dash of red pepper flakes to really amp up the heat.

How to Store and Reheat

Store leftover soup in an airtight container in the fridge for up to three to four days. 

Reheat in a pan on the stove over medium heat, and add a splash of broth as needed to thin out the consistency. Just be careful not to let the soup come to a boil! 

Can I Freeze Leftover Cauliflower Soup?

We don’t recommend freezing leftovers after the cream has been added. However, you can freeze it before adding the cream! 

To do so, allow the soup to cool. Then, transfer it to a freezer-safe container, and freeze for up to two months. 

To serve, thaw your soup in the fridge overnight. Then, warm it back up on the stove, add a splash of cream followed by the toppings, and enjoy! 

Serving Suggestions

This easy cauliflower soup can easily be enjoyed on its own. However, you can never go wrong with a side or appetizer like cheesy focaccia bread or a tomato and burrata salad with za’atar

Or, enjoy the soup as a starter with main courses like Mediterranean sun-dried tomato chicken meatballs, roasted chicken, or beef pot roast

    Unbelievable! Really easy to prepare and really flavorful. I used a Vitamix to puree and got a really velvety texture. I did garnish with za’atar but not croutons. Everyone agreed it needed more salt. Easily fixed. I will add more next time when roasting vegetables. Highly recommend this soup.

    1. Thank you for the feedback, Vivian! We’re so glad you were able to adjust it and enjoyed the recipe!
