Roasting cauliflower in the oven has become my go-to method for preparing it, as opposed to steaming. Roasting at a high heat really helps to sweeten and caramelize the cauliflower. I like to keep the entire head intact, take off any greens, and cut it in big slices.
Pre-heat oven to 400 degrees, while you prepare the cauliflower. Once you have cut the cauliflower in thick slices, lay them on a sheet pan and drizzle liberally with extra virgin olive oil and salt. Turn them over and repeat. Bake in the oven for 20 to 30 minutes, turning them over mid process, so both sides get nice and brown. The cauliflower will become caramelized and so incredibly tasty. Enjoy!
