Cauliflower Cheese is comfort food at its best and this keto version is one of the tastiest I’ve ever had. Topped with a speedy low carb crumb and fresh thyme gives it a special extra twist that’s sure to please.

Serve with your favourite side of protein or as an accompaniment with Sunday lunch. Roasting the cauliflower first makes it extra tasty. I hope you enjoy it as much as I did.

Hi there, could this be frozen?


Yes, you could freeze this for a few weeks.


I wonder if you could use Bacons Heir bacon breadcrumbs to make the topping. I can’t do the almond flour. The bacons heir breadcrumbs are a great binder in meatloaf. Looks dlelicious.  Ant wait to try it.


I'm not familiar with those but based on what I found on Google they look like pork rinds and should be ok for keto.


Just making sure I understand—you use the double batch of cheese sauce in this recipe? Or just half the prepared cheese sauce? Thanks!


Hi Debbie, you should use the amount listed in this recipe above - that is equal to a double batch of my cheese sauce: The Best Keto Cheese Sauce


This looks good. Hearty and healthy at the same time.


Do you use almond flour or pieces?  In one place you have one and in the instructions you have the other.


Hi Cathy, almond flour is the same as "ground almonds". There are, however "defatted" types of almond flour in which case I would specifically mention that in the ingredients. I hope this helps!


I'll admit to not being a huge fan of cauliflower. Even so, this dish looks really good. That says a lot about the recipe and your photography is great as well.


I think you'll like it. I made a version of this meal (with bacon topping instead of the flax-nut topping) for my mum last time and she is not keen on cauliflower either. But she loved it! 😊


Did you just crumble bacon on top or did you add it to other ingredients. I think with the bacon topping I could get my husband to try this.


I added crisped up bacon bits in the cauliflower & cheese before baking it but I think that raw bacon slices on top would work too 😊
