Air Fryer Pork Tenderloin is the perfect, quick dinner that's packed with flavor but only uses a few simple ingredients. With a tangy balsamic vinegar marinade, this juicy pork is also fancy enough to serve at a dinner party.
With paper towels, pat the pork dry. Cut away the silver skin, the shiny tough membrane you'll see on the side. Transfer the pork to a baking dish.
In a small bowl, stir marinade ingredients together. Pour over the pork. Let marinate at room temperature for at least 15 minutes (or up to 30 minutes), or cover and refrigerate for up to 1 day. When ready to cook, let the pork come to room temperature first.
Preheat your air fryer to 400°F. Add the pork (cut it into half crosswise if it is too large and add it in two pieces; check the cook time 2 minutes early). Air fry for 11 to 14 minutes. The pork is done when an instant-read thermometer measures the internal temperature of 145°F at the meat's center. Let it rest for 3-5 minutes before slicing(I remove the pork from the air fryer a few degrees before as it will continue to rise while resting).
Remove the pork to a plate. Cover and let rest 5 to 10 minutes. Cut into slices and enjoy!
A low-sodium soy sauce will work if you don't have Worceschire sauce.
Dijon mustard, black pepper, and chili paste are also great additions to the marinade.
Storing Leftovers: Leftover pork tenderloin can be stored in the refrigerator in an airtight container for up to 3 days. It can then be reheated in the oven, air fryer, or microwave.
