The Instant Pot makes the most delicious soups! You get that long, slow cooked flavor in a fraction of the time. Here are some of my favorite Instant Pot soup recipes:

Ingredients You'll Need
- Cauliflower- one large head, or two small. It should come out to 5 cups of cauliflower florets.

- Cheese- Shredded sharp cheddar, white cheddar, Colby Jack, or your favorite type of shredded cheese.
- Parmesan- To add a little more salt and flavor to the soup.
- Dry Mustard- Add a depth of flavor and brings out the flavor of the cheese in the soup.

How To Cut A Cauliflower
When you are first looking at a cauliflower it can be very intimidating. To wash and clean a cauliflower, first wash it under cold water. Remove the outside leaves that may still be on the cauliflower from harvesting.
With a sharp knife, cut the cauliflower in half. You will see the core on the inside of the cauliflower where it grows on the plant. Cut a triangle into the cauliflower to remove the core and discard the core.
Take the remaining head of the cauliflower and cut it into florets. Florets are a small piece of cauliflower with a little bit of the stem still on it. Add all those florets to a bowl and set it aside.
Let's Make Loaded Instant Pot Cauliflower Soup!
Clean and trim the cauliflower and cut the cauliflower into florets. Set the florets aside in a bowl.
Cut and chop the onions and garlic. Add one tablespoon of olive oil into the bottom of the Instant Pot. Add the chopped onion and minced garlic to the oil. Set the Instant Pot to "saute" mode and saute for 3 minutes, until the onions start to soften. Add the cauliflower florets, chicken broth, and dry mustard to the Instant Pot. Cancel "saute" mode, close the lid of the Instant Pot, and set the Instant Pot to "High" pressure for 15 minutes.
After 15 minutes, quick release the pressure from the Instant Pot. Be very careful when doing this step as the chicken broth can come out the steam valve and the chicken broth is very hot.
With an immersion blender, blend the soup until it is a creamy, velvety consistency. Turn the Instant Pot back to "Saute" and add the milk and cheeses. Mix the soup until the cheese is melted. Serve immediately.

Tips and Tricks
- Serve this soup with sourdough bread or sourdough bread rolls. The bread will soak up the soup and it's always fun to dip!
- If you don't have an immersion blender, ladle the soup into a blender or a Vitamix and blend until the soup is the consistency you are happy with. You can't over blend this soup.
- You can make this soup half broccoli and half cauliflower! Just add use half the amount cauliflower and substitute broccoli for the other half.
- Taste the soup after you add the cheese. Cheese tends to have a high salt content, so you don't want to add too much salt to the soup and overpower it.
