Step 1:
Prepare the Brussels sprouts by trimming the ends and removing any yellow or damaged outer leaves. Slice them in half to ensure even cooking.

Step 2:
Place the Brussels sprouts in a large bowl. Drizzle them with olive oil and toss them well to ensure they are evenly coated.

Step 3:
Sprinkle garlic powder, onion powder, salt, and pepper over the Brussels sprouts. Toss again to distribute the seasonings evenly.

Step 4:
Preheat your air fryer to 375°F (190°C). Once preheated, arrange the Brussels sprouts in a single layer in the air fryer basket. Avoid overcrowding them to ensure even crisping.

Step 5:
Air fry for 15-18 minutes, shaking the basket halfway through. For extra crispiness, cook for a few more minutes if needed.
