Preheat oven to 425 degrees F. Spray a medium baking sheet with nonstick spray.
Spread broccoli in a single layer onto prepared baking sheet. Mix together olive oil and garlic. Drizzle mixture over broccoli. Sprinkle Parmesan all over the top.
Toss to coat then make sure broccoli is back in a single layer. Season with salt and pepper.
Bake for 10 minutes. Carefully flip/toss broccoli then bake another 15 minutes or until tender. Serve warm and enjoy!
