Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for a few minutes. Preheating ensures even cooking.

Season the Brussels Sprouts (Optional): In a large bowl, place the frozen Brussels sprouts. If desired, drizzle them with a small amount of olive oil for added crispiness and flavor. Season with salt, pepper, and any other seasonings you prefer, such as garlic powder or herbs. Toss the Brussels sprouts to coat them evenly with the seasonings.

Arrange in the Air Fryer Basket: Place the seasoned frozen Brussels sprouts in a single layer in the air fryer basket. Avoid overcrowding; you may need to cook them in batches depending on the size of your air fryer. This ensures even cooking and maximum crispiness.

Air Fry the Brussels Sprouts:

Cook the Brussels sprouts in the preheated air fryer for approximately 15-20 minutes, shaking the basket or flipping the Brussels sprouts halfway through the cooking time. The exact cooking time may vary depending on the size and thickness of the Brussels sprouts and your air fryer model.

The Brussels sprouts are ready when they are tender on the inside and have a crispy, golden-brown exterior. Keep an eye on them to avoid overcooking.

Serve: Once the frozen Brussels sprouts are cooked to your desired level of crispiness, transfer them to a serving plate. You can garnish them with additional seasonings or a squeeze of lemon juice if desired.

Enjoy: Serve your Air Fryer Frozen Brussels Sprouts as a delightful and crispy side dish. They pair well with various main courses or can be enjoyed on their own.
