This Instant Pot Cauliflower Soup is QUICK, EASY, and hands-off thanks to the Instant Pot. Make it in under 30 minutes! Naturally gluten free – no flour required!

Everyone is raving about Zupa’s Wisconsin Cauliflower Soup, and for good reason! It is a healthy(er) soup made with a cauliflower base.

It is perfectly creamy and bursting with flavor – SO. GOOD. Well, the only thing better than that soup is this Instant Pot Cauliflower Soup that is every bit as tasty, but with much less prep!

We love to serve cauliflower soup with our Gluten Free Rolls or a loaf of fresh Gluten Free Sandwich Bread. If you’re looking for something quick you can pick up at the store, Against the Grain and  Udi’s both make a fantastic gluten free baguette!

You might also love the fact that we’ve adapted this recipe to require no flour, so you can enjoy it whether you’re gluten free or not and don’t have to worry about which flour to buy.

LET’S TALK ABOUT THE INGREDIENTS.

The Onions.

You’ll want to use a plain old yellow onion for this recipe. Since you’ll be blending the veggies after briefly cooking them, you don’t need to chop them finely, just give them a rough chop for sauteing and be on your way.

In the video, you’ll see that the onions and cauliflower are in fairly large pieces.

The Cauliflower.

We list specific weights in the recipe, but don’t be intimidated by that. If you have a kitchen scale and can weigh the cauliflower florets, GREAT. If you don’t, no stress.

Try to weigh the cauliflower before you buy it and then just remove the leaves, stem, and core. If it’s a little too much or too little, it shouldn’t affect the soup enough to be worrisome.

Our only advice here is, if you finish the instant pot cauliflower soup and it’s too thick for your taste, add more cream or broth to your liking. If it’s a little too thin, add an extra sprinkling of cheese to thicken it up.

If you like broccoli, we sometimes substitute half of the cauliflower for broccoli. Or, if you want to go all in, try this Instant Pot Broccoli Cheddar Soup recipe.

The Cheese.

Feel free to use your favorite combination of cheeses, just be sure that all of them are varieties that melt well. Sharp cheddar is perfect for this recipe, and you can absolutely use 100% sharp cheddar in this recipe if you want to keep it simple.

We’ve made this instant pot cauliflower soup a good half a dozen times now and so far, our favorite cheese combo is sharp cheddar/Gruyere/pepper jack.

Gruyere is a high quality cheese that is a little more expensive, and you’ll find it in the fresh cheese section of your favorite grocery store. It is similar in flavor to Swiss and melts incredibly, and it is this flavor/texture combo that make it ideal for this recipe.

Whenever you are making a recipe with melted cheese, use a block that has been freshly grated by you. Do not use pre-shredded cheese because it has added starch to prevent it from sticking. This starch will affect the consistency of the soup in a slimy sort of way…and no one wants slimy soup!

The Cream.

You might be wondering…”Can I make this instant pot cauliflower soup dairy free?“

The answer is…we’re not sure. We haven’t tried this recipe with any dairy free subs, but based on the amount of cheese and cream, we would suggest keeping this recipe as-is or finding another cauliflower soup recipe that is made specifically to be dairy free.

You might also ask “Can the cream can be swapped for half and half or even milk?“

We haven’t tried this either, but do have plans to give it a shot. The soup will, of course, be a thinner consistency so if you try it, please start out with a little less milk or half-and-half and add more if needed.
