For extra crispy cauliflower, try broiling for the last 2-3 minutes, keeping a close eye to prevent burning. A sprinkle of red pepper flakes adds a delightful touch of heat. Feel free to experiment with other cheeses! Pecorino Romano or Asiago would also be delicious. For a deeper flavor, try roasting the garlic cloves whole alongside the cauliflower. Once roasted, mash the garlic and mix it with the cauliflower before adding the Parmesan.
