Here are all the ingredients needed to make your own cauliflower soup. Roasted cauliflower soup ingredients ready to be cooked!

What do I need to make roasted cauliflower soup?

Here is a quick list of ingredients. This recipe is very heavy on the vegetables like my Crock Pot Loaded Bacon Baked Potato Soup which I love. It is a new and fun way to serve up a lot of vegetables in one dish without having to twist anyone’s arm to eat them!

This image shows us the cauliflower in florets ready to be roasted for our soup recipe.

  • 1 large head of cauliflower, cut into florets
  • 1 yellow onion, diced
  • 2 cloves of garlic, minced
  • 3 tablespoons olive oil
  • 4 cups vegetable broth (32 ounces)
  • ½ cup heavy cream
  • 1 teaspoon cumin
  • ½ teaspoon coriander
  • Salt and pepper to taste

Next we have to saute the rest of the ingredients for our cauliflower soup.

Can I use pre-cut cauliflower?

You can use cauliflower that has already been cut into florets if you like. It will probably save you some time versus breaking down a head of cauliflower before you make the recipe. Whatever is easiest for you will work fine in the recipe.

Plenty of seasoning makes this roasted cauliflower recipe flavorful and delicious.

If you are cutting the cauliflower on your own, try to make sure the pieces are generally the same size. If they are the same size they will roast more evenly and the cooking time will be plenty to get them nice and soft, and roasted to perfection.

How to make the most delicious roasted cauliflower soup:

Enough talk about this beauty of a recipe. Let’s dive in! This is a really simple recipe. It comes down to a few easy steps. We need to roast the cauliflower, add some flavor with our sauteed veggies, and then build creaminess.

Making roasted cauliflower soup is easy with such a flavorful broth!

The texture will be perfect but you have to blend until it’s smooth, completely smooth…or you’ll have lumps. Which won’t really impact the flavor but it might be off putting for those of you who prefer a completely smooth texture.

This image shows the cream being added to the roasted cauliflower soup so it can be thinned out and served.

If you want to make this recipe even more flavorful you can top it off with something fresh. Add in some fresh scallions, chives, or parsley. A little pop of something green to really set it off!
