Tips for the Best Roasted Cauliflower

Although roasting cauliflower is pretty simple, there are definitely a few tips and tricks that will make it just that bit more extra special.

  • I find that slicing the cauliflower into flat sections makes for a better roast keto cauliflower than simply breaking it up into florets. This way, the flat sides get super crispy as they cook – texture is key!
  • Always be sure to line your pan with parchment paper to avoid sticking.
  • Give the cauliflower a good head start in the oven before adding in the parmesan, otherwise the cheese will burn (do this only in the last 10 minutes or so).
