Place the Brussels Sprouts in a microwave-safe dish
Add ⅓ cup of water and microwave on high for 5 minutes
Let them cool down
Smash the Brussels sprouts with a flat dish. If you have a tortilla press that works best!
Try to keep the same thickness for all of them to cook them evenly
Coat them with olive oil, garlic powder and salt and pepper
Place them in the air fryer without crowding the basket.
Cook at 350 F for 10 minutes and flip them. Cook on the other side for 5 more minutes
Serve and sprinkle parmesan cheese (optional)
