Cauliflower nuggets. Ingredients raw cauliflower roasting pan Cut the cauliflower and spread out on the roasting pan. Turn the oven on to 400 degrees (no need to pre-heat) and stick the pan in there for 30-50 minutes. Then set the oven to “high broil” and broil 2-3 more minutes, depending on how crispy you like it. (I usually turn the oven completely off after this and leave the cauliflower inside for another 20 or so minutes.) Serve with bbq sauce or ranch dressing, for dipping.
