In a medium bowl add trimmed Brussel sprouts and season with salt, pepper, onion powder and 1 tablespoon oil.
1 pound Brussel Sprouts, Salt and pepper to taste, 1 teaspoon onion powder, 1 tablespoon olive oil
If your Air Fryer preheats then: Preheat air fryer to 400 Fahrenheit according to manufacturer instructions.
Lightly spray the air fryer basket with vegetable oil (not essential and you can get away with only 1 tablespoon of oil that was added to Brussel sprouts before but spraying does ensure better cooking and a more crisp texture in the end) and add the vegetables.
Air fry for 5 minutes, shake and gently stir, add parmesan and fry for another 5-6 minutes until charred and crisp. If using fresh garlic add it here now.
¼ cup Parmesan, 1 clove Fresh garlic
If you didn't preheat your air fryer you may need to add an additional 5 minutes.
Serve with more parmesan or bacon on top.
