Air frying pork tenderloin is a great way to keep the meat juicy but well cooked. These are important to consider when making sure your pork tenderloin doesn't dry out when cooking: - The marinade also adds moisture and keeps the meat from drying out - The air fryer seals in the juices in that small space so the meat doesn't dry out at all. - Resting the tenderloin after cooking is important to keep the meat juicy - Use a meat thermometer! This ensures the meat doesn't overcook and dry out.
