Set your air fryer to 370°F (188°C). Preheating helps cook the sausages evenly.
If you're using olive oil, lightly brush each sausage with it. This step is optional but can help to achieve a crispier exterior.
Arrange the frozen Italian sausages in the air fryer basket. Make sure to space them out so they're not touching, allowing for better air circulation.
Cook the sausages for about 10-15 minutes. Halfway through the cooking time, open the air fryer and turn the sausages to ensure even cooking.
The sausages are done when they reach an internal temperature of 160°F (71°C). Use a meat thermometer to check. They should be nicely browned on the outside.
Let the sausages rest for a few minutes after cooking. This helps to redistribute the juices inside, ensuring they’re juicy and flavorful.
Serve the Italian sausages hot. They pair well with a variety of sides, such as roasted vegetables, pasta, or a fresh salad. Don’t forget to add your favorite condiments!
