Clean one head of cauliflower by removing the stem, leaves, and core and rinsing it off. Pat dry and place in a dutch oven.
Combine your ghee, olive oil, salt, pepper, parsley, garlic, lemon zest, and red pepper flakes in a bowl.
Microwave for 10 - 15 seconds to melt the ghee.
Slather this mixture all over your cauliflower using a silicone pastry brush or your fingers.
Bake at 400°F, covered with the lid of your dutch oven or with foil for 30 minutes.
Remove the lid/foil and bake at 425°F for an additional 15 minutes.
If your cauliflower is soft enough to pierce through with a knife, it is done. If you cannot pierce the cauliflower easily, cover and bake for another 5 - 10 minutes. Your cauliflower should be easy to pull apart.
Carefully remove from the pan and pull apart to eat/serve.
