Preheat oven to 350f and set the first rack in the middle and the other rack to the top ⅓ of the oven.
Saute the garlic in the butter and oil for 2-3 minutes over medium-low heat or until fragrant. Turn off the heat and add in the crushed red pepper flakes and parsley along with a pinch of salt (to taste).
Split the bread lengthwise and open it up like a book. Brush or pour the garlic butter all over the bread making sure to evenly distribute it. Sprinkle with the Pecorino then cover with foil.
Bake for 12 minutes on the lower rack then remove the foil and move the bread to the higher rack. Broil for 1-3 minutes or until the bread is golden around the sides and sizzling but not burnt. Watch the whole time and be prepared to remove it quickly.
Once finished, slice the bread and serve. Enjoy!
