I haven’t been one to make much mashed cauliflower since I have been low carb because I never thought it tasted like anything worth eating.  The cauliflower never pureed super smooth and it always ended up watery.

I finally had a lightbulb moment and realized the Instant Pot would be perfect for making the cauliflower super soft without it being waterlogged from boiling.

The Instant Pot isn’t my first choice when it comes to making vegetables because they come out mushy…but that is perfect for mashed cauliflower!


The first thing I did was trim all of the leaves and stem from the bottom of the cauliflower but I left the head intact.  This really made this mashed cauliflower so easy!


Next, l pulled out my Instant Pot and placed the trivet inside.  Then I added 1/2 cup of water,  followed by the head of cauliflower.

I placed the lid on the pot and set it to sealing.  Then I set the timer for 5 minutes on high pressure.

When the time was up I did a quick release and removed the lid.

I used mitts to pull the trivet with the cauliflower out of the pot.  You can see just how tender this cauliflower is!

I then put it all in a food processor with butter, cream cheese, pepper and salt.

I only had to run the food processor for about 30 seconds to get this fully pureed.  For best results, scrape the sides and puree for about 10 seconds more.

It is so creamy and delicious!  I was actually shocked with how good it was the first time I tried it.  Even my picky husband liked it!

Serve it plain or with a big pat of butter and some chives.

You could also add some roasted garlic to the food processor before you puree to make garlic mashed cauliflower.
