Cheesy Cauliflower Mash - Keto, low carb cauliflower puree (2024)

This keto cauliflower mash is better than mashed potatoes. Change my mind. Just kidding – you can’t. A bold claim, but I stand behind it. And believe me, nobody is more surprised than I am at how delicious this low carb cheesy cauliflower puree is!

If you’ve tried keto cauliflower mash or cauliflower puree before and found it lacking, I totally feel your pain!

I’be been on various low carb diets since the 90’s (1990’s – I’m not THAT old), and had heard many people tout mashed cauliflower as an acceptable substitute for mashed potatoes. I’d tried it a few times and always…..meh, not so great.

I think part of the problem for me is that keto cauliflower purees always seem too watery and don’t have that true starchy mouth feel of real potatoes. I had long ago put mashed cauliflowerin the category of “better than nothing but nowhere near as good as mashed potatoes.”

Steaming or boiling the cauliflower always ends up in a watery, greyish, flavorless mess. If that’s been your experience, then I’m excited to introduce you to this keto cauliflower mash recipe – where I solved the problem by microwaving the cauliflower uncovered, which concentrates the flavors and also allows a lot of the liquid to evaporate while cooking, leaving you with a much thicker end result.

In addition to the consistency issue, my other problem with low carb cauliflower mash recipes has always been the funky, skunky flavor natural to cauliflower. The addition of a strong Irish cheddar cheese made all the difference! It embraced the funk and transformed it into a complex flavor that I couldn’t get enough of!

The naturally sweet flavor of the cooked cauliflower paired with the extra sharp cheddar in this cauliflower puree made regular mashed potatoes seem boring and one note by comparison. And I’m a person who loves mashed potatoes!

If you’re on the fence, and are worried about being disappointed yet again by another keto mashed cauliflower recipe claiming to replace mashed potatoes, then I implore you to scroll down and the read the comments of all the people who were skeptical at first, but had their minds blown when they gave this cauliflower puree recipe a try.

Tips for Making the Best Cauliflower Puree

Be sure to watch the recipe video in this post to see how we do it, and how easy it is – even when making smallish batches.

First, try to choose a head of cauliflower that feels heavy, and has tightly packed florets. If the head is loose and there is a lot of visible stem, you will likely end up with a grainy cauliflower mash from the thick membrane on the outer stem. If using stems and they seem thick, peel them with a paring knife to get that membrane off and you will be rewarded with the creamiest cauliflower puree of your life.

Second, be sure to trim your cauliflower into pieces that are no more than 2 inches in size. If you cook the cauliflower and there are some tiny pieces and some huge pieces, you will inevitably be left with some that are overcooked and shriveled, as well as some cauliflower pieces that are left raw in the middle – that will also result in a grainy puree.

If you can’t get Irish cheddar, a decent brand of extra sharp grocery store cheddar (like cabot or Cracker Barrel) will do – but don’t use the cheapest brand, or anything pre-shredded, or you won’t get nearly enough flavor to balance out your cauliflower mash.

Which Appliance Works the Best

If you read through the comments you’ll find that people did not have great results with blending this cauliflower mash in a food processor. If it’s what you’ve got, then it’s better than nothing, but you’ll find that it will not produce a creamy, smooth cauliflower mash – it’s just not built for that.

My favorite way to make this cheesy cauliflower mash is in my Nutribullet because I can easily shake up the cup to redistribute the cauliflower pieces while blending.

When making larger batches, I have made it in my trusty Blendtec blender (and back in the day my Vitamix) with good results, but it can be annoying to have to remove the lid multiple times to stir the mixture with a spatula to get it to blend. Since we are looking for a nice, thick consistency to our cauliflower mash, we don’t want to add more liquid to make it blend too easily or it will be a very loose puree.

So for that reason my favorite appliance for making this recipe is the NutriBullet, or some other kind of bullet style blender.
