pork tenderloin: Most pork tenderloin weighs between 1 and 1 ½ pounds but occasionally you may come across 2 pound packages. Because this is an air fryer recipe, go with the smaller package so it all fits in one batch.
extra virgin olive oil: This will create the base of our marinade.
balsamic vinegar: A little healthy acid will accelerate the marinating process and will produce supremely tender pork.
Dijon mustard: This lovely condiment adds great flavor for the marinade.
fresh or dried thyme: Pork and thyme just go so beautifully together. One of my favorite ways to glam up boring meat is to add fresh herbs.
garlic powder: For more flavor and a great addition to the pork marinade.
sea salt: Always use good quality unrefined salt for all your cooking.

Helpful Tips for Juicy Pork

🕐Avoid dry pork: In order to get juicy and moist pork is to make sure you don't overcook the meat. I like to pull it out of the oven when internal temperature reaches 140 degrees Fahrenheit and it will continue to rise with residual heat. Additionally, make sure you let the pork rest after cooking!
🚫Food Safety: On the opposite side of dry pork, you want to make sure to avoid under-cooked pork. According to USDA, 145 degrees Fahrenheit is the safe internal temperature for pork muscle meat, even if there is still some pink present.

💭Make it Nutrient-Dense: Because pork has a higher fat content than other animals, it's always best to source pastured and heritage-breed pork. Wild Pastures is a great option with US raised pastured pork.

This easy pork tenderloin recipe calls for these basic ingredients: pork tenderloin, extra virgin olive oil, balsamic vinegar, Dijon mustard, fresh or dried thyme, garlic powder, and sea salt.

marinade with balsamic vinegar, oil, and seasonings.

Step 1. Make the marinade

In a small bowl, combine extra virgin olive oil, balsamic vinegar, Dijon mustard, fresh or dried thyme, garlic powder, and sea salt.

Step 2. Prepare pork tenderloin

Pat dry pork tenderloin. Trim excess fat if necessary but remember fat adds flavor so don't overdo the trimming. Remove the thin silver film with sharp knife if present on the tenderloin.

💭Pro tip: For most recipes, you can substitute fresh herbs with dried herbs using a 3:1 ratio. For example, for this tenderloin marinade, use 1 teaspoon dried thyme or 3 teaspoons of fresh thyme.

Step 3. Cover pork with marinade

Step 4. Marinate

Cover with lid or plastic wrap and marinade for 30 minutes at room temperature or overnight in the refrigerator.

💭Pro tip: If marinating in the refrigerator, don't forget to allow time for the pork tenderloin to come to room temperature before roasting.

Step 5. Cook in Air Fryer

Don't forget to preheat the air fryer and pull out the pork tenderloin from the refrigerator before roasting! 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.

Step 6. Rest the meat

This is a very important step and must not be missed! You have to let the pork tenderloin rest at least 10 minutes. The internal temperature of the meat will continue to rise during this time and juices will remain, yielding a very juicy pork tenderloin.

💭Pro tip: Cook times will vary depending on your air fryer. Roast the pork tenderloin until internal temperature registers at 140-145 degrees Fahrenheit. Generally, basket-type air fryers will cook about 3-5 minutes faster than toaster-oven convection air fryers.

FAQs

What cut is pork tenderloin?

Pork tenderloin, also called pork fillet, is considered the filet mignon of pork. It usually comes as a long, narrow, boneless cut of meat that comes from the backbone muscle. It's a lean cut yet when cooked right, is tender and flavorful.

How can I avoid drying out the pork?

The best way to achieve moist and juicy pork is to cook it at high temperature for lowest amount of time necessary. Roast pork tenderloin in your air fryer at 400 degrees Fahrenheit for 12-15 minutes or until internal temperature reaches 145 degrees Fahrenheit. Remove pork immediately after reaching this temperature. It's also important to allow the meat to rest after cooking to let the juices settle in the meat.
