Homemade Broccoli Cheese Potato Soup In The Instant Pot

Whether it’s a winter day with a chill in the air, broccoli potato cheese soup is always on the list to make. And fresh veggies from the garden, make it even better. We use the Instant Pot and the soup comes together very quickly..

This recipe is versatile enough where you can make it with frozen or fresh broccoli. Whichever you have on hand, the pressure cooker will cook the veggies in the soup into perfection.

If you read anything on this post, don’t add milk into the Instant Pot before cooking or it will curdle the milk.

What Can I Substitute For Chicken Broth?

If you don’t have chicken broth or chicken stock, you can use a bouillon cube or water seasoned with salt and pepper. If you don’t want to use chicken, you could also use a vegetable broth.

Is Broccoli Cheddar Potato Soup Chunky or Smooth?

This potato soup is a chunky recipe. Turn it into a creamy soup by using an immersion blender to cream the soup. You can puree the soup to your desired consistency right in the Pot.

  • If you want your vegetables smaller, you could use a food processor
  • Cooking time includes the estimated time you are waiting for the soup on natural release pressure
  • Frozen veggies are fine to use for this recipe
