In a small bowl, combine extra virgin olive oil, balsamic vinegar, Dijon mustard, fresh or dried thyme, garlic powder, and sea salt.
Pat dry pork tenderloin and trim excess fat if necessary. Brush the marinade over the pork making sure to cover all sides well. Cover and marinade for 15 minutes at room temperature or overnight in the refrigerator.
Preheat air fryer to 400 degrees Fahrenheit. Air fry pork tenderloin for 12-15 minutes if using a toaster-oven type. For air fryer basket-types, start checking on the pork at the 10 minute mark.
When internal meat temperature reaches 140 degrees Fahrenheit, remove pork from air fryer and allow to rest for 10 minutes. During this time, the temperature will continue to rise from residual heat.
Cut pork tenderloin across into 1" slices and serve warm.
Notes
If marinating in the refrigerator, bring the pork tenderloin to room temperature before roasting.
Cook times will vary depending on your air fryer. Roast the pork tenderloin until internal temperature registers at 140-145 degrees Fahrenheit. Air Fryer basket type will cook about 3-5 minutes faster than toaster-oven convection air fryers.
It's important to allow the cooked pork to rest after roasting. The juices will assimilate back into the meat to yield juicy pork.
