Creating Crispy Air Fryer Brussels Sprouts is a breeze if you follow these simple steps:

1. Prepare the Brussels Sprouts: Rinse the Brussels sprouts under cold water. Trim the stem ends and remove any yellow or damaged leaves.
2. Cut in Half: Slice each Brussels sprout in half lengthwise for even cooking.
3. Season: In a large bowl, toss the halved Brussels sprouts with olive oil, garlic powder, onion powder, salt, black pepper, and red pepper flakes (if using) until evenly coated.
4. Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for about 5 minutes.
5. Air Fry: Place the seasoned Brussels sprouts in the air fryer basket in a single layer. Cook for 12-15 minutes, shaking the basket halfway through for even cooking.
6. Check for Doneness: After 12 minutes, check the Brussels sprouts. They should be crispy and golden brown. If necessary, cook for an additional 2-3 minutes.
7. Serve: Remove the Brussels sprouts from the air fryer and drizzle with balsamic vinegar and sprinkle with grated Parmesan cheese if desired.

These steps will ensure you achieve the perfect crispy texture and flavor!
