Place Cauliflower on cutting board and cut it vertically from top to bottom into slices about 3/4 of an inch thick. You should get 3-4 intact slices, the rest will fall away into florets (cook these as well).
In a large deep dish (like a pie pan or a casserole pan) add Panko, Parmesan, Garlic Powder, Onion Powder, Thyme, Red Pepper Flakes, Salt, and Pepper.
Blend the dry ingredients together and spread it out covering the bottom of the pan.
In another large deep dish add in the Egg and Coconut Milk.
Whisk until mixed.
Take each slice of Cauliflower and dip all sides including the top into the Egg mixture.
Next dip each slice into the Panko mixture covering all sides and top of Cauliflower.
Add the Cauliflower onto a parchment lined baking sheet (or just spray the pan with non-stick cooking spray if you don’t have parchment paper).
Bake 15 minutes.
Flip Cauliflower over and bake additional 15 minutes.
