Preheat the oven to 425 degrees F. Wash and trim broccoli into florets and stems.
On a large baking sheet, sprinkle the broccoli minced garlic, then drizzle with 2 tablespoons of the olive oil and season with salt and pepper. Toss to coat evenly.
Roast broccoli in the oven for 14-18 minutes, tossing halfway through, until lightly browned on bottoms or around edges and the broccoli is tender-crisp.
Transfer roasted broccoli with garlic to a bowl and toss with remaining olive oil, lemon juice, and Parmesan cheese. Taste and season with additional salt or pepper as needed. Serve immediately.
