Wash and dry your brussels sprouts then cut each one in half.

Drizzle enough olive oil all over your sheet pan to cover it well. Then start dipping the cut side of each brussels sprout in the olive oil and coat them well. Leave each sprout cut side down and add more oil as you need it to keep each sprout cut side coated in oil.

When you are done arranging all of your sprouts,, preheat the oven to 450°. Season your sprouts with the salt, pepper, Garlic powder, and pepper flakes. Sometimes I drizzle a little of the olive oil over the top of them too for good measure. Bake for around 30 minutes,,unless they are really small sprouts then you might cut back on the time.
