I’m reminding you about this Roasted Cauliflower with Parmesan for today’s Friday Favorites pick and this is  a low-carb side dish that will always be a hit. And through many, many years of roasting different kinds of vegetables, this  is a roasted vegetable dish I’ve made over and over.

I first made this in the very early days of my blog, and I thought I’d about covered the roasted cauliflower possibilities, but it surprised me a few years ago when a failed cooking experiment for Air Fryer cauliflower led to a new and improved version of this recipe.

It happened when my nephew Jake and I tried roasting cauliflower in the Air Fryer and then tossing it with Parmesan, and it was definitely not a winner. But we had the roasted cauliflower that we’d tossed with Parmesan and the oven was hot from another recipe, so we put the cauliflower into a big casserole dish and put it in the oven, just to melt the cheese a bit before we ate it.

And WOW! The melted cheese in the hot oven formed a crispy Parmesan crust on the bottom of the dish. And the new version of Roasted Cauliflower with Parmesan was such a treat that I decided to update this long-time favorite cauliflower recipe, and that’s how this improved way of making this recipe was born! Since then I have made this so much more often, and I hope you’ll try it if you like the sound of roasted cauliflower that’s cooked with melty Parmesan cheese!

What Parmesan is best for Roasted Cauliflower with Parmesan?

I would use freshly-grated Parmesan or purchased Parmesan that’s coarsely-grated for this recipe. I’m not sure how it would work with the finely-grated Parmesan that comes in a can.

Roasted Cauliflower with Parmesan is a delicious low-carb side dish, and I've updated this recipe with a new trick that makes this favorite side dish even better.


  • 1 very large head cauliflower, cut into bite-sized florets
  • 2 T olive oil (see notes)
  • salt and fresh-ground black pepper to taste
  • 1/2 cup  freshly grated Parmesan cheese (see notes)


  1. Preheat oven to 450F/230C. Use the largest flat casserole dish you have and spray with non-stick spray.
  2. Cut away the core of the cauliflower, then cut into small bite-sized florets. Try to make them all the same size and on the small side so they'll all get nicely browned at the same time. (To cut the cauliflower without getting a lot of "crumbs", cut through the stem, then pull the floret apart. This trick works well with broccoli too.)
  3. Put the cauliflower pieces in a large plastic bowl, add olive oil, and toss until the cauliflower pieces are all lightly coated with oil.  (Start with a bit less olive oil and add more if it's not enough to cover the cauliflower.)
  4. Season to taste with salt and fresh-ground black pepper, then toss with the grated Parmesan. (Adjust the amount of cheese depending on how big your head of cauliflower was.)
  5. Roast cauliflower for 15 minutes. Then remove pan from oven and use a large flat turner to flip the cauliflower over so the melted cheese is on top. Roast 15 minutes longer, or until cauliflower is cooked through and nicely browned.
  6. Serve hot. This can be reheated in the microwave or in a hot pan, although it's best freshly made.


You need enough olive oil to coat all the cauliflower florets with oil. Use more or less grated Parmesan depending on the size of your head of cauliflower; I used coarsely grated cheese.
