How to cook a pork tenderloin in an air fryer
This recipe is so easy! First we start by preheating the air fryer to a very hot 400 degrees F–This will help to quickly begin building a caramelized crust on the outside. While the air fryer is preheating, mix your spice rub, drizzle with a bit of oil, and rub the spice mixture all over the tenderloin.
When you place the pork tenderloin into the air fryer, reduce the temperature to 390 degrees F. Cook for 10 minutes, then flip and continue cooking for 5 more minutes. Be sure to check the internal temperature with a meat thermometer–When it reaches 145, remove and allow the pork to rest for 5 minutes before slicing and serving.
What to serve with pork tenderloin
When you don’t want to heat up the kitchen with a large appliance, this pork tenderloin and delicious spice rub would complement easy side dishes like Sweet Corn Salsa or this Cucumber Avocado Salad. For a more classic dinner, serve with Cheesy Roasted Asparagus or this Cheesy Cauliflower Casserole!
For a great keto dinner for only about 5 net carbs, serve the tenderloin with Keto Bacon Wrapped Green Beans and a Three Cheese Keto Biscuit!
Can you make pork tenderloin ahead of time?
Yes, this recipe can be made ahead of time and then stored in an airtight container in the fridge up to 3 days. You can also freeze and store up to 4 months (it’s safe longer, but the taste and texture are best within 4 months).
To freeze, double wrap as tightly as you can and store in a freezer bag with all the air squeezed out. You can freeze individual-sized portions (great for pulling out for lunches or meals for one) or the entire cooked tenderloin.
How to reheat pork tenderloin
Because pork tenderloin is so lean, it can easily dry out if you don’t reheat it correctly. Here are my favorite ways to reheat pork tenderloin without it drying out. You do want your tenderloin already sliced into medallions before reheating–This will speed up the process, giving the pork less time to dry out.
Skillet – Using a skillet with a tight-fitting lid, heat to medium and add a small coating of olive oil. Once it’s warm enough that the oil shimmers, add your pork medallions in a single layer. Place the lid on the skillet, flipping and checking every minute until heated throughout. If your medallions are 1/2 inch thick, you can expect them to reheat in about 3 minutes.
Air Fryer or Oven – Make a foil pouch for your pork medallions. With the pork in a single layer, sprinkle about 1 teaspoon of water or broth per serving and seal the pouch. Place directly onto the oven rack, on a baking sheet, or in the air fryer basket.
For the oven, preheat to 325 and allow it to reheat 10-20 minutes (depending on how much you’re reheating at once). For the air fryer, preheat to 250 degrees and reheat 5-10 minutes.
Microwave – place the pork medallions on a plate with about a teaspoon of water or broth per serving. Cover with a damp paper towel and reheat on 50% power in 30 second increments until warmed throughout.
