01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper to ensure easy cleanup.
02 - In a large bowl, toss broccoli florets with olive oil, minced garlic, sea salt, and freshly ground black pepper until evenly coated.
03 - Spread the seasoned broccoli in a single layer on the prepared baking sheet, avoiding overcrowding for even roasting.
04 - Roast in the preheated oven for 18 to 20 minutes, turning once halfway through, until the florets are crisp on the edges and tender inside.
05 - Remove from oven and immediately sprinkle with grated Parmesan cheese. Toss gently to coat the broccoli evenly.
06 - Transfer to a serving platter and garnish with lemon zest and chopped parsley if desired. Serve warm.
