Thinner Consistency: If you like a thinner soup consistency, add hot homemade unsalted chicken stock to adjust the thickness of the soup.
Smaller Cauliflower Florets: break the larger pieces into smaller florets, so it'll be easier to blend.
Crispy Bacon: It's important to place the bacon in the cold pot before turning on the heat (see tips).

Step-by-Step Instant Pot Cauliflower Potato Soup Cooking Guide

Prepare Ingredients for cooking Cauliflower Potato Soup in Instant Pot:

Instant Pot Cauliflower Soup Ingredients #AmyJacky #InstantPot #PressureCooker #recipe #soup #LowCarb

What does red potatoes, bacon, Parmesan cheese, fish sauce, and garlic have in common?

They pair extremely well with cauliflower!

Tips for Instant Pot Cauliflower Potato Soup

1. Purchasing White Cauliflower: Look for clean, creamy white, tightly packed florets = fresh cauliflower!

2. Cooking Crispy Bacon

  • In order to cook the meat and fat evenly, crispy, and not burnt, place them in the cold pot before turning on the heat. Then, let the heat slowly render out the pork fat.
  • It’s also important to absorb the bacon’s excess fat with paper towel after sauteing – this helps crisp up the umami bacon bits!

3. Smaller Cauliflower Florets: Break the larger pieces into smaller florets, so it’ll be easier to blend.

4. Fish Sauce: Fish sauce is an optional ingredient, but it adds a kick of irresistible umami-ness to the hearty soup. Don’t worry! It won’t taste fishy. 😉

5. Thinner Consistency: If you like a thinner soup consistency, add hot unsalted chicken stock to adjust the thickness of the soup.

Made this tonight. I omitted regular onion. My cauliflower was small so I reduced chicken broth to 3 cups. I used potato masher because we like the soup with chunks. I added cream but it wasn’t as thick so thicken it up with corn starch & water, perfect. When I served it I sprinkled dill on top. Very good soup. Tasted just like my cream of potato soup recipe. It is a keeper. I have a 4quart crockpot express.

I want to try this tonight but I do not have fish sauce. Any ideas for a substitute? I do have anchovy paste. Maybe a smidge would work here?

I made this tonight, and my 5 year old & 3 year old asked for seconds! They didn’t want any part of it when I was chilling up the cauliflower. They smelled the aroma once I opened up the instant pot and couldn’t wait for me to dish it out for them!
