Place the frozen broccoli florets in a large resealable bag or mixing bowl. Add the minced garlic, olive oil, salt, and black pepper. Toss well to ensure the broccoli is evenly coated.
Transfer the broccoli to the air fryer basket or tray, arranging it in a single layer. Set the air fryer to 400°F (200°C) and cook for 10–12 minutes, shaking the basket halfway through cooking, until the florets are tender-crisp and slightly browned.
While the broccoli is cooking, zest and juice the lemon.
Remove the broccoli from the air fryer. Drizzle with lemon juice, sprinkle with lemon zest, and top with grated Parmesan cheese. Serve immediately while hot.

Asian-Inspired: Add 1 teaspoon soy sauce and 1/2 teaspoon sesame oil to the olive oil mixture before cooking.
