Spread thin garlic slices, red chili flakes, sea salt, freshly ground pepper and drizzle generous amount of olive oil over the broccoli.
Using your fingers gently coat every florets with olive and spices.
Arrange broccoli with flatter side down on the baking tray. DO NOT OVER CROWD the pan.
Roast broccoli in pre heated oven at 450 degree Fahrenheit, stirring it once half way through.
NOTE: roasting time will depend hugely on the size of the broccoli florets.
I made thin slices of broccoli from the florets and my roasting time was 12 minutes. Note I did not roast until broccoli was brown. Took it out a minute or two early, so it was just beginning to brown. I love that texture of broccoli where stem is tender and the edges are slightly crispy and brown. This is personal preference!
When almost cooked through, remove tray from oven, sprinkle all the cheese on top and place it back in the oven and continue roasted for another 2 to 3 minutes or until cheese begins to melt.
Roast broccoli until it’s done. ‘Done’ can mean it’s roasted nicely and turned brown or you can stop it when edges begin to turn brown, and stems are tender. The way you prefer.
Pro-Tip: if you want crispy roast broccoli, broil the broccoli for 2 minutes at the end of roasting time.
Remove from the oven and serve it immediately.
