  • Place the beef tenderloin into the air fryer basket and air fry for 6 minutes.
  • Reduce the heat to 350 degrees F / 180 degrees C and continue to cook the tenderloin for another 12-15 minutes, or until the internal temperature of the middle of the tenderloin reaches 120 degrees F / 49 C (for medium rare)using an instant read thermometer.

Notes

  • Look for meat that is well marbled and even in size across the whole piece of meat.
  • Remove the silver skin and any excess fat and tie with butcher's twine. You can ask your butcher to trim and tie the tenderloin for you. 
  • Bring the beef tenderloin to room temperature for 45 minutes before air frying. 
  • The herb butter should be softened but not melted. 
  • Prepare the compound butter mixture up to 2 days in advance. 
  • If using dried herbs, reduce the amounts as they can be more potent. 
  • Preheat the air fryer for even cooking. 
  • Spray the air fryer basket with olive oil spray to reduce sticking.
  • Use a meat thermometer to check for doneness. Don’t rely solely on the clock. 
  • Meat will continue to cook after removing it from the air fryer. Pull the meat a few degrees below your desired temperature to account for carryover cooking and avoid overdone meat. 
  • See the temperature chart for desired doneness above. 
  • Let the meat rest for 10-12 minutes before slicing and serving to allow the juices to redistribute through the meat.
  • Storage - keep leftovers in an airtight container inside the fridge for 4 days.
