How Do You Make Cheesy Cauliflower Soup in the Instant Pot?
The process of making this cauliflower soup is SO simple.
You start off by sauteing some onions and garlic in the Instant Pot.
Next, you’ll add some cauliflower florets and some broth, along with salt and pepper.
Cook that for a few minutes, then use an immersion blender to puree it to your desired consistency. I like mine smooth, but you can leave some chunks in if you prefer!
Then, you’ll add in a slurry of flour and water. This helps thicken the soup a little, and it will thicken even more when we add the cheese.
Which brings me to the most glorious part of this soup–the CHEESE! I used two different types of cheese: sharp white cheddar and pepper jack.
If you don’t have sharp white cheddar, you can use sharp yellow cheddar. The pepper jack adds some additional flavor, but it doesn’t make it super spicy (I’m a wimp when it comes to spice, and this wasn’t too spicy at all).
What Toppings Can I Add to Cauliflower Soup?
The sky is the limit when it comes to toppings! I kept things simple and added some shredded Colby Jack cheese and some chives.
Crumbled bacon would be a delightful addition, or you could dollop some sour cream on top.
Wanna kick up the spice? Add some sliced jalapenos! Need some crunch? Sprinkle croutons on top.
So many options, and you can keep it simple or go all out!

This creamy, cheesy cauliflower soup cooks up quickly in the Instant Pot! It's a great way to sneak in some veggies!
Ingredients
- 2 Tbsp olive oil
- 1 small sweet onion, diced
- 1 Tbsp minced garlic
- 1 medium head of cauliflower, chopped into florets (about 2 cups)
- 4 cups chicken broth or vegetable broth
- 1/2 tsp salt
- 1/4 tsp black pepper
- 3/4 cup milk
- 1/4 cup flour
- 1 cup shredded pepper jack cheese
- 2 cups shredded sharp white cheddar cheese
- Optional: Additional shredded cheese and sliced chives for serving
Instructions
- In the insert pot of the Instant Pot, add olive oil and diced onions. Using the Saute function, cook the onions for a couple of minutes until they begin to turn translucent.
- Add minced garlic and stir for about thirty seconds, until it becomes fragrant. Turn off the Saute function by pressing Cancel.
- Add chopped cauliflower, broth, salt and pepper.
- Select a cook time of five minutes at high pressure. When the cook time is complete, perform a quick release of pressure.
- After the pressure has released and the valve has dropped, carefully remove the lid and press Cancel to turn off the pressure cooker. Use an immersion blender to puree the soup to your desired consistency.
- Create a slurry by whisking together milk and flour. Pour into the hot soup, stirring to combine. Allow this to thicken for a couple of minutes, stirring occasionally (if needed, you can use the Saute function to simmer the soup).
- Add the shredded cheese, stirring until melted.
- Serve, topped with additional shredded cheese and chives, if desired.
Notes
- I used sharp white cheddar and pepper jack cheese in this soup. If you don't have white cheddar, feel free to substitute yellow cheddar instead.
- Topping Ideas: Extra cheese (I used Colby Jack, but you can use pretty much any variety here!), sour cream, chives, crumbled bacon, sliced jalapenos, croutons or oyster crackers.
- To make this vegetarian, use vegetable broth instead of chicken broth.
- To make this gluten-free, use cornstarch or arrowroot powder instead of flour.
