Preheat the air fryer to 375°F (190°C).
Lightly spray the sausages with olive oil (optional) and season with your preferred spices or marinades. Place the sausages in a single layer in the air fryer basket, ensuring there’s enough space between them for proper air circulation.
Air fry for 10-12 minutes (fresh sausages) or 12-15 minutes (frozen sausages), flipping halfway through for even cooking.
Check the internal temperature, ensuring it reaches 165°F (74°C).
Serve immediately with your favorite sides.
