Cauliflower is one of several vegetables in the species Brassica oleracea in the genusBrassica, which is in the family Brassicaceae. It is an annual plant that reproduces by seed. Typically, only the head is eaten – the edible white flesh sometimes called "curd" (with a similar appearance to cheese curd). The cauliflower head is composed of a white inflorescence meristem. Cauliflower heads resemble those in broccoli, which differs in having flower buds as the edible portion. Brassica oleracea also includes broccoli, Brussels sprouts, cabbage, collard greens, and kale, collectively called"cole" crops, though they are of different cultivar groups.
Preheat a cast iron tray in the oven at 400F.
Combine the cauliflower and garlic in a bowl. Add olive oil and salt and toss to combine.
Transfer the cauliflower to the pre-heated tray and bake at 400F until golden brown.
