Preheat oven to 350℉.
Next, slice the bread into 1 inch slices, being careful not to slice all the way through the bread. Place the loaf onto a parchment or foil lined sheet pan.
Add the garlic cloves and red pepper flakes to a small ramekin. Cover with olive oil. Place inside oven and cook for 20-25 minutes until the garlic is fork tender. Let cool completely.
Remove garlic from oil (reserve oil for later use.). Using a fork, smash garlic cloves.
In a small bowl, combine softened butter, cooked garlic, garlic powder, Italian seasoning, parsley, and parmesan cheese. Season with salt.
Using a small offset spatula, generously spread mixture into all the slits of the bread.
Wrap bread in foil and bake for 15 minutes. Remove foil and bake for an additional 5 minutes.
