What size Instant Pot did I use?

For those who haven’t caught the Instant Pot fever just yet, I’m going to give stovetop direction as well, because this soup would be super simple to make on the stove.

Instant Pot (or Stovetop) Loaded Cauliflower Soup
TInstant Pot Loaded Cauliflower Soup is a soup recipe you'll make over and over, and this tasty soup is even a hit with people who say they don't like cauliflower!
Ingredients
- 1/2 onion, chopped small
- 2 T butter or olive oil
- 1 large head of cauliflower, trimmed and coarsely chopped.
- 3 cups chicken stock, plus a little more to thin soup if needed
- 1 tsp. garlic powder
- 1 tsp. kosher salt
- 4 oz. cream cheese, cut into cubes
- 1 cup grated extra sharp cheddar cheese
- 1/2 cup half and half (or use heavy cream or milk if you prefer)
Topping Ingredients:
- extra grated sharp cheddar or extra sharp cheddar cheese (optional)
- sour cream (optional)
- 8-10 strips bacon, cooked crisp and crumbled (optional)
- thinly sliced green onions (optional)
Instructions
- Peel onion and chop into small pieces.
- Cut away the leaves of the cauliflower and some of the stem, keeping the core part. Coarsely chop cauliflower into pieces.
- Turn Instant Pot or pressure cooker to SAUTE and melt the butter; then add the onion and cook 2-3 minutes.
- Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
- Lock the lid, use the MANUAL setting and cook on HIGH PRESSURE for 5 minutes.
- Quick release the pressure.
- While the soup cooks, prepare the cream cheese cubes, grated sharp cheddar, and half and half. Also cook and crumble the bacon, dish up sour some sour cream and extra grated cheese, and slice the green onions for toppings.
- Check to make sure the cauliflower is very tender; then turn the Instant Pot to KEEP WARM (use simmer or low for other pressure cookers.)
- Use an immersion blender (affiliate link) blender, or food processor to puree the soup. (I highly recommend using an immersion blender to puree the soup in the pressure cooker if you have one. Be very careful with the hot liquid if you remove it to a blender or food processor to puree.)
- Check the thickness of the soup and add more stock if you want it thinner or simmer a little to reduce if it seems too thin.
- Add the grated cheese and cream cheese cubes and let them melt, then stir to combine.
- Add the half and half (or heavy cream or milk) heat through, and season with salt and fresh-ground black pepper. (Taste before you add more salt.)
- Serve hot, with grated cheese, sour cream, crumbled bacon, and green onion to add at the table
Stovetop Directions:
- Prepare ingredients as described above, but use 3 1/2 cups chicken stock for stovetop version. Use a heavy dutch-oven type pan that will hold all the ingredients.
- Heat butter or oil in the dutch oven, add the onion, cook 2-3 minutes.
- Then add the chopped cauliflower, chicken stock, garlic powder, and salt.
- Bring to a boil, then turn heat to medium-low and simmer until the cauliflower is very soft, probably 20-30 minutes.
- Puree soup as above, and check the amount of liquid. If it's too thick add a little more stock and if it seems thin, cook a few minutes more to evaporate some of the liquid.
- Turn heat to low, add the grated cheese and cream cheese cubes and let them melt, then stir to combine.
- Add the half and half (or heavy cream or milk) and heat through, and season with salt and fresh-ground black pepper. (Taste before you add more salt.)
- Serve hot, with grated cheese, sour cream, crumbled bacon, and green onion to add at the table as desired.

I haven’t done it that way. But if you look back in the comments, there are some tips from people who have done it that way.
This soup is delicious. Thanks so much!
So glad you enjoyed it!
I am wondering if I could use cauliflower rice instead of a whole cauliflower.  The stores don’t have cauliflower when I get my delivery.
Yes, I think that will work just fine, enjoy!
Folllwed recipe to a T except there is no cheddar cheese in the house. Â Used one cup shredded parm instead. Â Added the crisped bacon on top. Â Delish! Â The hubs and I had a hard time not eating it all. Seriously that good. Â And managed to put maybe a serving or two away for later.
So glad you enjoyed it! And good work on the improvising. We are all doing that right now.
This recipe is amazing. Just made it and even my non-keto hubby approved. SOOOOOOOOOOOOOOOOOOOOOOOOOO Good. Thanks.
So glad you enjoyed! And it’s always good when you find one the husband likes too.
I used my instant pot, but my cream cheese never melted, not even when soup was heated up in the microwave. Any tips there?
I have no idea what would cause that. The melting temperature for soft U.S. cream cheese is 130F, so certainly it should melt completely in the IP. As you can see from the comments many, many people have made it following this recipe.
Did you use regular cream cheese?
Yes, it still tasted great–just weird looking because the cream cheese chunks were kind of floating around. Maybe it’s because I bought off-brand cream cheese 😀
Surprisingly delicious and lots of flavor! Â This will be one of my favorite go-tos It was so easy to make! Thank you.
So glad you enjoyed!
When I calculated again, the chicken stock was definitely coming up wrong on some values. So I calculated other ingredients and used a carton of chicken stock from my cupboard as the amounts for that, then added them together. I can’t guarantee this is completely accurate either, but it seems more accurate than what the automatic calculator came up with! Thanks for catching that.
Yes, that has to be wrong. I am having help doing them so i will calculate myself and see what I get. The automatic calculator is often wrong on certain ingredients, so it’s easy to make a mistake.
No, it does not include the toppings; since I don’t know which ones and how much people will eat that’s hard to calculate. I will edit to make that more clear.
Can the leftovers be frozen?
Yes, this will freeze well.
I haven’t tried doubling this recipe so I can’t say for sure. I don’t know if it will be too full in a 6 quart Instant Pot, but be sure ingredients aren’t above the max fill line. If you’d like to try I found this info about how to double a recipe in the Instant Pot.
I just happened to buy some cauliflower today and then got this recipe in my email. I made the soup exactly as written except I didn’t have the heavy cream or milk. It was delicious.  Thanks Kalyn for this amazing recipe; it’s a keeper.Â
This was delicious. I used Swanson chicken stock and 1/3 less fat cream cheese. Added a couple shakes of cayenne pepper at the end. Will definitely make again.
Thanks, so glad you enjoyed!
I made this today according to the recipe (stovetop method) & decided after mashing it with a potato masher to leave the texture. It was super yummy & a big hit with my husband. Super fast to make too!
So glad you enjoyed! Personally I like chunky soup so I bet I’d like that too!
Really good soup. I’ve made faux-tatoes and cauliflower rice, but this is the best low-carb cauliflower recipe that I’ve had yet. Tastes a lot like baked potato with all of the trimmings. Easy to make and a “keeper”. I will enjoy it as lunch in the coming week. Personally, I like a little black pepper on top (some things I keep traditional ;-)…). It’s also one of those recipes that you could probably double if you have a lot of people to feed… they won’t realize it’s “diet food”, lol… except for missing the “carb coma” later…
Glad you enjoyed!
I made this soup today, I just happen to have all the ingredients since I’m doing keto, my girlfriends boys hate everything, they smelled the soup progress, and asked for some….SCORE!!!!!!!
I absolutely love hearing that!
I absolutely LOVE this soup and have made it many times. I’d like to make a batch for a friend, so can you freeze this soup?
I think it will freeze, but sadly I have never had any left over to try freezing so I can’t say for sure. If you try it I’d love to hear how it goes.
Love to have low carb soups or meal recipes
Glad you like it; I am a big soup fan!
Excellent recipe with no hint that it is actually cauliflower. I used frozen cauliflower and increased IP time to 7 minute. Other than that, I followed the recipe as written. Thank you!
So glad you enjoyed it and glad to hear how it worked with frozen cauliflower!
Hi Kimberly,Â
Was the cauliflower frozen when you placed in the pot, or did you steam ahead of time?Â
