01 - Preheat your oven to 425°F. Line a large baking sheet with parchment paper or foil for easy cleanup.
02 - In a large bowl, toss the broccoli florets with olive oil, sliced garlic, salt, and black pepper until evenly coated.
03 - Spread the broccoli in a single layer on the prepared baking sheet, ensuring the florets are not overcrowded.
04 - Roast for 18–20 minutes, stirring halfway through, until the broccoli is tender and the edges are golden brown.
05 - Remove from the oven and immediately sprinkle with Parmesan cheese. Toss gently so the cheese melts slightly over the hot broccoli.
06 - If desired, drizzle with lemon juice, sprinkle with lemon zest, and garnish with parsley before serving.
