Preheat the oven to 425 F, option to line a baking sheet with parchment paper for easy cleanup.
Place broccoli on prepared baking sheet, and sprinkle evenly with garlic. Drizzle with olive oil then spread into a single layer on your baking sheet. Sprinkle with salt and pepper, and bake in preheated oven until the broccoli is slightly crisp, 20-25 minutes.
Remove broccoli from the oven. While still hot, sprinkle with parmesan and toss to coat. Serve warm, and enjoy!
