This guide will walk you through every step, from picking the right cut to letting it rest, so you get a fantastic result every single time.
Pork tenderloin is a lean, tender cut that can dry out if overcooked. The air fryer’s rapid hot air circulation solves this by cooking it fast and sealing in those juices. With a few simple tips, you’ll have a centerpiece meal that feels gourmet without the fuss.
How To Roast Pork Tenderloin In Air Fryer
This section is your master recipe. Follow these steps closely for a perfectly cooked, juicy pork tenderloin. The key is in the preparation and not skipping the rest time at the end.
What You’ll Need
- 1 pork tenderloin (about 1 to 1.5 pounds)
- 1–2 tablespoons of oil (olive, avocado, or vegetable oil work well)
- Your favorite dry rub or seasoning blend (see ideas below)
- Kitchen twine (optional, for tying if the tenderloin is uneven)
- Meat thermometer (this is non-negotiable for perfect doneness)
- Air fryer
Step-by-Step Instructions
1. Prep the Pork Tenderloin
Start by patting the tenderloin completely dry with paper towels. This is crucial for getting a good sear. If there’s a tough silver skin on one side, use a sharp knife to carefully slide underneath it and remove it. This membrane won’t render down and can make the meat tough.
If your tenderloin has a thin, tail-like end, you can tuck it under and tie it with kitchen twine so the whole piece cooks evenly. Drizzle the oil over the meat and rub it all over. Then, generously apply your dry seasoning, pressing it into the surface on all sides.
2. Preheat Your Air Fryer
For the best results, preheat your air fryer to 400°F (200°C) for about 3-5 minutes. Preheating ensures the cooking environment is immediately hot, which helps create that desirable crust right away. Not all models require this, but it generally leads to more consistent outcomes.
3. Cooking Time and Temperature
Place the seasoned tenderloin in the air fryer basket. You usually don’t need to add oil to the basket itself because the meat is already coated. Cook at 400°F (200°C).
The general rule is 12-15 minutes per pound. However, because air fryers vary, the only reliable way to know when it’s done is with a meat thermometer. Start checking the internal temperature about 5 minutes before you think it should be done.
4. Checking for Doneness
Insert a meat thermometer into the thickest part of the tenderloin. The USDA recommends cooking pork to a minimum safe temperature of 145°F (63°C). At this temperature, the pork will be slightly pink in the center and incredibly juicy.
Do not overcook it! The temperature will continue to rise a few degrees while the meat rests (the next critical step). Remove it from the air fryer when it reads about 140-142°F (60-61°C).
5. The Most Important Step: Resting
This step cannot be skipped if you want juicy meat. Transfer the cooked tenderloin to a cutting board and loosely tent it with foil. Let it rest for 5-10 minutes.
Resting allows the hot juices, which have been forced to the center of the meat, to redistribute back throughout the entire cut. If you slice it immediately, all those flavorful juices will just run out onto the board, leaving you with drier meat.
Best Seasonings and Marinades
A simple seasoning can make your pork tenderloin shine. Here are a few easy combinations to try:
- Classic Herbs: Salt, black pepper, garlic powder, onion powder, dried rosemary, and thyme.
- Sweet & Smoky: Brown sugar, smoked paprika, chili powder, salt, and a pinch of cumin.
- Simple & Zesty: Salt, pepper, lemon zest, and dried oregano.
- Asian-Inspired: Mix soy sauce, minced garlic, grated ginger, and a little honey for a quick 30-minute marinade before patting dry and applying a light oil coat.
Remember, if you use a wet marinade, make sure to pat the tenderloin very dry before adding oil and any additional dry rub. Excess moisture will steam the meat instead of letting it roast properly.
Common Mistakes to Avoid
Even with a simple recipe, small errors can affect the outcome. Here’s what to watch out for:
- Not Using a Thermometer: Guessing doneness is the fastest way to overcook lean pork. A instant-read thermometer is your best friend in the kitchen.
- Skipping the Preheat: While not always required, starting with a hot air fryer gives you a better sear.
- Crowding the Basket: Ensure there’s space around the tenderloin for air to circulate. If cooking two, don’t let them touch.
- Skipping the Rest: We’ve said it before, but it’s worth repeating. Let the meat rest before you slice into it.
- Using the Wrong Cut: Pork tenderloin is long, thin, and usually around 1-1.5 lbs. Don’t confuse it with a wider, fattier pork loin roast, which requires a different cooking time.
Serving Suggestions
Once rested, slice your juicy air fryer pork tenderloin into ½-inch to 1-inch thick medallions. Here are some great ways to serve it:
- With simple sides like roasted air fryer potatoes, steamed green beans, or a crisp apple salad.
- Drizzled with a pan sauce made from deglazing the air fryer basket (add a little broth, mustard, and cream to the drippings in a small saucepan).
- Leftovers are fantastic sliced cold in sandwiches or chopped into salads for lunch the next day.
The versatility of pork tenderloin is one of it’s best features. It pairs well with so many flavors, from hearty fall vegetables to light summer salads.
Storing and Reheating Leftovers
Store any leftover pork in an airtight container in the refrigerator for up to 3-4 days. To reheat it without drying it out, use a lower temperature.
Place slices in the air fryer at 325°F (160°C) for 2-4 minutes, just until warmed through. You can also reheat gently in a covered skillet with a splash of broth or water. Avoid the microwave, as it will likely make the meat tough and rubbery.
FAQ Section
How long to cook pork tenderloin in air fryer?
At 400°F (200°C), cook for 12-15 minutes per pound. Always use a meat thermometer to check for an internal temperature of 145°F (63°C) for safe, juicy pork.
