Preheat oven to 425 F. Drizzle a little olive oil on a baking sheet, then use a paper towel to rub the pan down.
In a large bowl, add broccoli, olive oil, garlic, and salt to taste. Toss broccoli with a spoon until it's completely coated.
Pour broccoli on the prepared baking sheet, spreading out into an even layer. Scoop out any garlic & oil left in the bowl and sprinkle it over the broccoli.
Bake for 10-12 minutes, or until broccoli is cooked through.
Sprinkle cooked broccoli with Parmesan cheese before serving.
