Preheat the air fryer to 375°F (190°C) for about 5 minutes.
In a large bowl, toss the halved Brussels sprouts with olive oil, garlic powder, smoked paprika, salt, and pepper until evenly coated.
Arrange the Brussels sprouts in a single layer in the air fryer basket. Avoid overcrowding; you may need to do this in batches.
Air fry the Brussels sprouts for 15-18 minutes, shaking the basket halfway through cooking to ensure even crispiness. They should be golden brown and crispy.
If using, remove the sprouts from the air fryer and toss them with grated parmesan cheese while still warm.
Serve hot, drizzled with balsamic glaze for added flavor and presentation.
Notes
For extra flavor, add balsamic glaze before serving.
