This versatile air fryer breakfast frittata recipe uses a cake pan that fits in the air fryer basket for fuss-free, light, and fluffy results.
Preheat an air fryer to 360 degrees F (180 degrees C). Spray a nonstick 6x2-inch cake pan with cooking spray.
Combine sausage, eggs, cheese, bell pepper, green onion, and cayenne pepper in a large bowl; mix well to combine.
Pour egg mixture into the prepared cake pan.
Cook in the preheated air fryer until frittata is set, 18 to 20 minutes.
