Preheat oven to 350 degrees and spray a 9" pie dish with cooking spray.
Trim the leaves and stems from the underside of the cauliflower and cut the bottom stem even with the florets so that the cauliflower sits flat.
Stir together the olive oil and garlic. Begin by brushing the bottom side of the cauliflower with the garlic oil. Season the underside and up inside the cauliflower head with salt. Turn the head over and brush the top liberally with the garlic oil. Season the head with salt and sprinkle with Parmesan cheese and red pepper flakes.
Place the cauliflower into the prepared pie dish and bake for 50–60 minutes or until the center of the cauliflower is tender when pierced with a knife and the exterior is golden brown.
Slice into wedges and serve nice and hot. Enjoy!
One Last Thing
If you don’t have fresh garlic, substitute with 1 tsp of garlic powder.
