Preheat your air fryer to 400°F (200°C).
Wash and dry the broccoli florets thoroughly.
In a large bowl, toss the broccoli with olive oil.
Add garlic powder, onion powder, salt, and pepper; mix well.
Place the seasoned broccoli in the air fryer basket in a single layer.
Cook the broccoli for 10-15 minutes, shaking the basket halfway through.
Check for desired crispiness; cook longer if needed.
Once cooked, drizzle with lemon juice for added flavor.
Remove from the air fryer and let cool slightly before serving.
Enjoy your crispy air fryer broccoli as a side dish or snack!
