Creamy Cauliflower Soup is the perfect comfort food for cold days. This easy vegetable soup is full of both flavor and nutrition!

Cauliflower Soup in a white bowl

This cauliflower soup is easy enough to make. You’ll start by sautéing your vegetables in a combination of butter and olive oil. We recommend using a combination of cauliflower, onion, celery, and carrots to build flavor. Don’t worry, cauliflower remains the star of the show here. Add in a hint of garlic flavor and thyme and oregano for our herb additions. This is all simmered in vegetable broth and milk for our creamy element and thickened slightly using cornstarch. The result is a creamy cauliflower soup the whole family will love!

  • Do I have to use vegetable broth? Can I use chicken broth instead?

    This cauliflower soup calls for vegetable broth as the main liquid ingredient to simmer our vegetables in, build flavor, and provide the basis for our soup. Vegetable broth is the preferred ingredient for this vegetable soup, but you CAN use chicken broth in its place. It will change the overall flavor from a lighter vegetable flavor, to a heavier meaty flavor even though there is no meat in this recipe.
  • How can I reduce the calories in this recipe?

    This recipe is fairly low in calories to begin with, but if you want an even lighter soup, it’s the milk that contains the majority of the calories. Milk is added in this recipe for that delicious creamy element. Instead of using milk, replace it with additional vegetable broth. Still want that creamy element? Remove 2 cups of the soup (including vegetables) and puree. Stir this pureed soup back into the pot and it will feel more creamy, without the additional calories from the milk.

This is delicious! I added a couple potatoes and an extra cup of broth. I also used my hand blender to make it smoother.?

Made this before, it’s awesome. Thinking of adding chicken?

I blended the soup to make it a cream (drinkable) soup. It was like velvet. Perfect texture and flavor.

Excellent recipe. I used flour because I didnt have corn starch and a little more olive oil and butter right before I added the flour…

This is delicious! I took the liberty of adding some diced ham and some shredded mild cheddar cheese, and that made it perfection! My husband thought it was the BEST!

Can this be frozen?

Yes, though you may experience some separation because of the milk. Dairy does not always freeze well.
