Tips to Perfect Mashed Cauliflower

Drain Cauliflower

Letting perfect whipped creamy mashed cauliflower is crazy easy – but I’m adding a couple extra tips for perfect mashed cauliflower!

Cauliflower gives off a LOT of moisture – I like to set it in a cheesecloth and squeeze out as much liquid as possible before mashing.

This will help give a good thick consistency, instead of being overly watery.

Mix Until Smooth

Since cauliflower doesn’t have the starched potatoes do, we’re not running a risk of overworking the cauliflower – it won’t turn gummy if you mix it more – so if you want no lumps, go for it!

If you’d like a little lumpy bits for extra texture, that’s fine too.

Make it perfect for your tastes!

Undercook Cauliflower Slightly

When cooking cauliflower to the perfect consistency for mashed cauliflower, it is better to very slightly undercook it.

Cauliflower should bee tender to the touch when pressed with the tines of a fork – but not so soft it smushes.

Leaving cauliflower in boiling water too long will make it very mushy and watery.

Make Ahead Mashed Cauliflower

Since I often make this keto mashed potato substitute on holidays like Thanksgiving, space and time is at a premium.

Luckily, this cauliflower recipe actually tastes better from reheating – so go ahead and make it a day early, then refrigerate in an airtight bowl and reheat by adding to a well-greased baking dish (or cover it in parchment paper), covered with foil.

Simply pop in the oven (add more parmesan or keto breadcrumbs for a little crunch!), and heat to piping hot, about 15 minutes.

I’ll often just pop it in with the rolls, after the turkey is cooked, so it is still hot when serving.

  1. This is so delicious! I added a little bit extra sharp white cheddar to mine and it was incredible. With or without the extra cheese, this stuff is delicious! My father-in-law absolutely raved over it!
