Instant Pot Broccoli Cheese Soup

Thick and creamy Instant Pot Broccoli Cheese Soup is a quick and easy, naturally gluten free broccoli cheddar soup prepared in only 15 minutes!

It started with a simple craving for healthy, homemade, thick and creamy Broccoli Cheese Soup in the instant pot.

What should have been an easy task to find THE PERFECT RECIPE sent me down a Google rabbit hole with an overwhelming amount of recipes, ingredients, and soup consistencies.

My brain literally turned into Broccoli Cheese Soup mush and I still didn’t have one recipe I was entirely convinced of. They were either not gluten free, extremely unhealthy, looked too blah, or weren’t easy to throw together.

So our family consumed a virtually 100% Broccoli Cheese Soup diet for the following weeks while I tried my hand at making THE PERFECT Instant Pot Broccoli Cheese Soup RECIPE.

You Say This is THE BEST BROCCOLI CHEESE SOUP recipe???

Try it for yourself and see. But if you need some convincing first, I’ve come prepared.

1. It takes 15 minutes! If you don’t have 15 minutes to make soup, go to Panera. (However, I must point out it will take longer than 15 minutes to go to Panera.)
2. The recipe requires only a handful of basic, wholesome ingredients.
3. Don’t have an instant pot or still scared to use it? I’ve included stove top directions too. Equal-Opportunity-Equipment soup here.
4. The taste is spot-on Broccoli Cheese Soup heaven!

How To Make Instant Pot Broccoli Cheese Soup Recipe

1. Cut broccoli in small florets. This eliminates the need to process the soup with a blender.
2. On the SAUTE function, cook onions and garlic until soft and translucent.
3. Add broccoli, chicken broth, salt, and pepper. Cook on HIGH pressure in the Instant Pot 2 minutes for fresh broccoli, 1 minute for frozen broccoli.
4. Quick release the pressure and change back to SAUTE function. Add cornstarch slurry to pot and boil until thickened.
5. Stir in cheese to melt. Slowly stir in half and half.

Can I Use Pre-Shredded Cheddar Cheese?

I’m not going to call the shredded cheddar police if you’d rather save your arm strength, but hear me out.

Bagged shredded cheddar has a tendency to leave a grainy texture. Manufacturers add cellulose to prevent the cheese from clumping together. The additives make the cheese not melt as smoothly.

So, although both types of cheese can be used interchangeably in the recipe, I find shredding your own cheese yields better results and it’s cheaper to boot!

How to Thicken or Thin Broccoli Cheddar Soup

This broccoli soup recipe uses 4 tablespoons cornstarch mixed with water because I love a thick, hearty soup. 

To thin the soup, either use 1-2 tablespoons less cornstarch mixed with less water or add additional milk or cream at the end.

To thicken broccoli cheese soup add softened cream cheese, additional cheddar, or more cornstarch mixed with water. 

Can I Substitute Other Kinds of Cheese?

Of course you can! I love using sharp or extra sharp cheddar because the cheese flavor shines through more than mild cheddar.

Some people prefer using Velveeta cheese in Broccoli Cheese Soup. Velveeta will guarantee smooth results and is very tasty, but the “cheese” flavor will be more subdued.

To make Velveeta Broccoli Cheese Soup in the instant pot replace the cheddar with 8 ounces cubed velveeta cheese. For velveeta cheese lovers, also check out Velveeta Mac and Cheese recipe!

A mixture of cheeses can also be used. Extra sharp cheddar, pepper jack, white cheddar, or gouda would also work perfectly!

Gluten Free Broccoli Cheddar Soup

This instant soup recipe is gluten free because it uses cornstarch as a thickener and all the other ingredients are naturally gluten free.

For a low carb or keto version of broccoli cheese soup, replace the cornstarch with xanthan gum. Generally 1 teaspoon of xanthan gum replaces 1 tablespoon cornstarch or flour, but I start with less because a little goes a long way!

For Low Carb / Keto Broccoli Cheese Soup in the instant pot, start with 2 teaspoons xanthan gum dissolved in 2 tablespoons water. Increase by the teaspoon (mixed with a little water) for thicker broccoli soup. 

Using Frozen Broccoli for Broccoli Cheese Soup in the Instant Pot

Fresh or frozen broccoli can be used in this Instant Pot Broccoli Cheddar Soup recipe. It’s just a matter of preference.

I’ve cooked it both ways and there is no noticeable difference between using fresh or frozen. Whichever used, though, make sure the broccoli is cut in small florets or use frozen florets (not stalks or chopped).

Using a smaller-sized broccoli eliminates the need to process the soup with a blender.

Substituting Milk, Cream, or Non-Dairy Milk in Broccoli Cheese Soup

This recipe calls for half and half because it’s creamy but doesn’t have as many calories as heavy cream.

Regular milk or non-dairy milk, such as almond milk may also be substituted. It would reduce the calories in the soup and make it even healthier. However, the soup will be thinner and not as rich tasting.

On the other hand, if you are looking for a richer taste use heavy cream and more power to you.👊

Can I Freeze Instant Pot Broccoli Cheddar Soup?

Broccoli Cheddar Soup can be frozen, BUT the soup may “break” or have a thinner consistency upon thawing.

Defrost the soup in the refrigerator and reheat gently on the stove. If the soup is thinner than desired mix together 2-4 tablespoons of cornstarch with equal amount of water.

Bring soup to a boil, add cornstarch slurry, and stir until thickened.
