Cauliflower, to be honest, is pretty bland by itself. It’s a great ingredient to use as a substitute for potato for sides like cauliflower mash or faux potato salad. We wanted to find a way to jazz up cauliflower. This keto cauliflower casserole transformed that bland cauliflower into delicious cheesey, creamy, bacon goodness.

Keto Cauliflower Casserole
BACON! Yes!!! Delicious. Lets add some leeks and try that. Oh Wow. This is it. We had no idea how this dish was going to turn out and we were totally surprised and impressed. This dish was a total surprise to us as to how well it turned out. So good that I was really excited when we had left overs for dinner the next day.
Roasting the cauliflower in the oven, rather than boiling or steaming it, reduces some of the water than comes out of it when cooking it. This ensures your finished bake is cheesey and delicious and not watery. Roasting the cauliflower also gives it a nice texture and flavour.
Cauliflower is great for keto!
Cauliflower is a fan favourite in the low carb community as it is a great substitute for potato and other carbs. Cauliflower rice is a really popular option, so much so that you can even buy it at the supermarket now! We love cauliflower rice or cauliflower mash with butter chicken or beef stroganoff, you will not miss regular rice, trust us.
