Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for about 3-5 minutes.
Prepare the Sausages: While the air fryer is heating up, season the sausages. If you prefer, rub them lightly with olive oil for added crispiness. Sprinkle with garlic powder, onion powder, fennel seeds, and red pepper flakes, ensuring they are evenly coated.
Place Sausages in Air Fryer Basket: Arrange the sausages in a single layer in the air fryer basket, leaving some space between each sausage for air circulation.
Air Fry the Sausages: Cook the sausages in the preheated air fryer at 375°F (190°C) for 12-15 minutes. Flip the sausages halfway through cooking for even browning.
Check for Doneness: To ensure the sausages are fully cooked, check the internal temperature with a meat thermometer. It should read 160°F (71°C).
Serve: Once the sausages are cooked through and crispy on the outside, remove them from the air fryer and let them rest for a few minutes. Serve immediately with your favorite side dishes.
