What does cauliflower taste like?

While cauliflower is a mild tasting vegetable, it doesn’t have the same neutral flavor you get with rice. In my opinion it’s highly ignored and not served as often as it should be. Coming in a few different colors, white is the most common.

We will share here how to make Instant Pot mashed cauliflower, how to cook a whole head in your multi cooker, as well as a cheesy version I’m addicted to. You can use your Ninja Foodi for any of these as well.

  • You could make them orange, green or yellow too depending on what color cauliflower you find at the store.
  • I used purple because I have 3 girls and well I thought that it would be “totally cool”!

This vegetable steamer is great for just about any veggie you want to make.

  • Just pour about 1 1/2 cups of water into the bottom of your Instant pot.
  • Open the steamer basket up as you see here
    • It includes a safety tool too that makes lifting the steamer out of your pot easier and safer too
  • Add your cauliflower florets
  • Close the lid and set to manual setting, pressure high for 3 minutes cook time
  • Release the pressure with a quick release once done
  • Remove the lid and put veggies into food processor or use potato masher to smooth

If you don’t have any of these you can find them on my list of favorite Instant Pot accessories. They aren’t expensive and I use them every week, totally worth it.

Once your cauliflower is nicely steamed and super soft you just pour it into a bowl, add your goodies, mix on low/medium to smooth it out, and serve!

Surprise them one night with this as a side item, I guarantee you’ll get a big “What??!! Cool!”….and they will try it!

How do you thicken cauliflower puree?

  • If left inside your Instant Pot and mashed you can thicken by cooking down further while stirring often while on the saute function or inside a nonstick skillet. To thin it out just whisk in additional liquid such as broth, cream, or water.

How long does mashed cauliflower keep?

Properly stored, cooked cauliflower will last for 3 to 5 days in the refrigerator. To further extend the duration, freeze it!

Can you freeze pureed cauliflower?

Of course! Just make sure you freeze leftovers in a covered airtight container or heavy duty freezer bag. You can also wrap what’s left with heavy duty aluminum foil or freezer wrap. We rarely have any left, it’s that good.
