By using balsamic vinegar as a base for our marinade, we’ll produce some amazing flavors for our pork tenderloin. This recipe is sweet, savory and absolutely delicious. It’s a perfect air fryer recipe to have an awesome dinner on your plate in under 30 minutes.
Make Sure It Says Pork Tenderloin
Pork tenderloin can frequently be confused with other similar cuts of pork. It’s important to know that actual pork tenderloin will always be labeled as such. You may see pork loin or pork loin filet, but these are NOT pork tenderloin and do not cook the same way. Pork tenderloin is a long, narrow and very lean cut of pork. It’s generally 1lb-1.5lbs in size (though that can vary slightly). It’s commonly sold in vacuum sealed packages, often with 2 tenderloins.
Easy Marinade
For our pork tenderloin marinade, we’ll use a combination of wet ingredients with a few dry seasonings. Chances are you probably have most of these ingredients on hand: Balsamic vinegar, soy sauce and lemon juice are the wet ingredients. For the seasonings we use dry crushed rosemary, onion powder, garlic powder, brown sugar, salt and pepper. That’s it!
To make things extra easy, we can mix all this up in a large zip-top bag. Once the tenderloin in placed in the bag with the marinade, seal it up and put it in the refrigerator. I love to let it marinate overnight for the most flavor possible. But, if you’re short on time, even a ½ hour will work. A couple of hours is even better.
Air Fry at 400° for 20 minutes
Pork tenderloin is done when it reaches an internal temperature of 145°(F). To achieve this, we’ll preheat the air fryer for 5 minutes at 400°. Then we’ll spray a little cooking spray in the basket (or tray if you’re using a tray style air fryer), place the marinated pork tenderloin inside, and use the air fry setting at 400° for 20 minutes. Pork tenderloins vary in size and air fryers vary as well. Smaller tenderloins may take as little as 16 minutes. Larger ones make take 22 minutes. Be sure to check internal temperature with an instant read thermometer for that perfect 145°(F).
Let it Rest
Once the pork tenderloin is done, remove it from the air fryer and place on a plate or cutting board and let it rest for 5 minutes before serving. Use a sharp knife and slice it into cuts of about ½″ thick. I love to serve with white rice and asparagus.
