1Preheat the air fryer to 180°C (350°F).
2Cut broccoli into small, uniform florets.
3In a bowl, toss florets with olive oil, minced garlic, salt, and pepper until well coated.
4Arrange broccoli in a single layer in the air fryer basket. Cook for 10–12 minutes, shaking the basket halfway, until tender and lightly golden.
5Transfer roasted broccoli to a serving bowl. Drizzle with lemon juice, sprinkle with grated Parmesan, and toss gently. Serve warm or at room temperature.
