Cook the Brussels Sprouts
1. Fill a large pot with water and bring to a boil, then add salt.
2. Add the Brussels sprouts to the boiling water and cook them until they are fork tender or for about 20 minutes.
3. Drain the pot carefully into a strainer and set aside the Brussels sprouts in a large bowl to cool enough to handle.
4. Mix together the Parmesan cheese, garlic powder, and onion powder in a bowl until well combined, then set aside.
5. Place the crisper plate into the air fryer basket.
6. Select the Air Fry function, adjust temperature to 450°F and time to 6 minutes, then tap Start/Pause to preheat.
7. Press down gently on the Brussels sprouts with a flat surface like a ramekin or mug as the air fryer is preheating.
8. Place a sheet of parchment paper carefully onto the preheated crisper plate.
9. Lay the Brussels sprouts side by side onto the parchment paper.
10. Coat the Brussels sprouts lightly with oil spray.
11. Select the Air Fry function, adjust temperature to 450°F and time to 9 minutes, then tap Start/Pause.
12. Flip during the last 3 minutes of cooking time and sprinkle the Parmesan cheese on top.
13. Remove the basket from the air fryer when done and let sit for 2 minutes to allow the Parmesan cheese to become crispy.
14. Slide the Brussels sprouts carefully off of the parchment paper and repeat with the rest.
15. Drizzle the balsamic glaze on top and garnish with parsley. Serve immediately.
