1. Prep your cauliflower – remove the root, wash & pat dry.
2. Combine olive oil, melted butter, garlic, lemon zest, salt & pepper and whisk together. Place the cauliflower upside down in a Dutch oven or deep pot. Pour about half of the mixture on it, making sure to get in the crevices. Flip the cauliflower over and pour the rest on the top. I use a brush or my hands to make sure it is all evenly coated. Cover with lid or foil and pop it in a 400 degree oven for about 40 minutes. Test if it’s ready by sticking a knife in it, making sure it goes though easily.
3. Remove but leave your oven on! Use a spoon to coat/baste the top of the cauliflower with the liquid in the pot. Then, put your parmesan all over the cauliflower making sure to coat pretty evenly. Pop it back in the 400 degree oven, uncovered, for approximately 5 minutes and then broil on low for approximately 10-15 minutes (until golden and crispy). You can broil on high if desired but watch carefully!
4. Remove from the oven and squeeze the juice of 1 lemon all over the cauliflower. Sprinkle with red pepper, parsley, and additional salt and pepper to taste. Slice it up and enjoy!
