After washing and drying the cauliflower thoroughly, discard the leaves and chop it into small florets.
Transfer to a food processor and pulse gently to obtain rice-size bits.
Put the cauliflower bits in a heat-safe bowl together with a tbsp of butter. Set the microwave to “cooking” and place the bowl in. Leave for 1 minute and 30 seconds.
Mix the cauliflower rice, almond flour, rosemary, oregano, eggs, and a cup of mozzarella cheese in a bowl. Using a spoon to stir well until combined. Adjust the flavor with salt and pepper.
Transfer the mixture to a waxed-paper-covered baking tray. Pat evenly on all sides.
Lay the remaining half cup of mozzarella cheese on top to cover the surface.
Leave in the oven set at 300°F for 15 minutes. Baking time may depend on how dry/moist you like your topping.
Remove from the oven once the cheese turns golden in color. Let stand for 5 minutes to cool then remove the paper. Serve.
