If you’re wondering ‘how long do i cook a pork tenderloin in an air fryer,’ you’ve come to the right place. The answer is surprisingly quick, typically between 12 to 20 minutes, but getting it perfectly juicy requires a few simple steps. This guide will walk you through everything from prep to perfect slicing.
Pork tenderloin is a fantastic cut for the air fryer. It’s lean, tender, and cooks fast with fantastic results. The hot, circulating air creates a beautiful, flavorful crust while keeping the inside wonderfully moist. It’s a nearly foolproof method for a quick weeknight dinner or an impressive meal for guests.
How Long Do I Cook a Pork Tenderloin In An Air Fryer
As mentioned, the core cooking time is usually 12 to 20 minutes at 400°F (200°C). The exact time depends on two main factors: the size of your tenderloin and your desired doneness. Most supermarket pork tenderloins weigh between 1 to 1.5 pounds. A 1-pound tenderloin will take about 12-15 minutes, while a 1.5-pound piece may need 18-20 minutes. Always use a meat thermometer to be sure.
Essential Tools and Ingredients
Before you start, gather what you need. Having everything ready makes the process smooth and easy.
- Pork Tenderloin: 1 to 1.5 lbs. Look for one that’s uniform in thickness for even cooking.
- Oil: A high-smoke point oil like avocado, canola, or olive oil.
- Seasonings: Salt, pepper, garlic powder, paprika, or your favorite dry rub.
- Meat Thermometer: This is non-negotiable for perfect results.
- Air Fryer: Any model will work, but cooking times might vary slightly.
- Tongs: For safely turning the meat.
Step-by-Step Cooking Instructions
Follow these numbered steps for a flawless pork tenderloin every single time.
Step 1: Prep the Pork
First, pat the tenderloin completely dry with paper towels. This is crucial for getting a good sear. If there’s a tough silver skin on the underside, use a sharp knife to carefully remove it. This membrane won’t render down and can make the meat tough.
Step 2: Season Generously
Drizzle the tenderloin with about a tablespoon of oil. Rub it all over the surface. Then, apply your seasonings liberally. A simple combo is 1 tsp salt, ½ tsp black pepper, 1 tsp garlic powder, and 1 tsp smoked paprika. Make sure to coat all sides evenly.
Step 3: Preheat the Air Fryer
Preheat your air fryer to 400°F (200°C) for about 3-5 minutes. Preheating helps start the cooking process immediately, leading to a better crust. Not all models require it, but it generally improves results.
Step 4: Cook and Check Temperature
Place the seasoned tenderloin in the air fryer basket. Cook for 10 minutes. Then, open the basket and flip the tenderloin over using tongs. Continue cooking for another 5-10 minutes. Start checking the internal temperature with your meat thermometer at the 12-minute mark.
- For slightly pink, juicy meat: 145°F (63°C). This is the USDA safe temperature.
- For well-done: 160°F (71°C). Be aware it may be drier.
Insert the thermometer into the thickest part of the meat. Remember that the temperature will rise a few degrees while resting.
Step 5: Rest Before Slicing
This might be the most important step! Once the pork reaches temp, transfer it to a cutting board. Tent it loosely with foil and let it rest for 5-10 minutes. This allows the juices to redistribute throughout the meat. If you slice it immediately, all those flavorful juices will run out onto the board.
Why Temperature is More Important Than Time
Cooking by time alone is risky. Air fryers can vary in power, and meat thickness changes everything. A reliable instant-read thermometer is your best tool for perfect doneness. It takes the guesswork out and ensures both safety and quality. Don’t rely on color alone.
Flavor Variations and Marinades
While a simple dry rub is excellent, you can easily change the flavor profile. If you use a wet marinade, be sure to pat the meat very dry before air frying. Excess moisture will steam the meat instead of browning it.
- Herb-Crusted: Rub with olive oil, minced fresh rosemary, thyme, salt, and pepper.
- Sweet and Smoky: Use a rub of brown sugar, chili powder, cumin, garlic powder, salt, and pepper.
- Asian-Inspired: Marinate for 30 mins in soy sauce, honey, ginger, and garlic. Pat dry before cooking.
- Mustard & Maple: Brush with a mix of Dijon mustard and a little maple syrup before seasoning.
Common Mistakes to Avoid
Avoiding these pitfalls will guarantee a better outcome. Even small changes can make a big difference.
- Skipping the Pat Dry: A wet surface prevents browning.
- Overcrowding the Basket: Leave space for air to circulate all around the meat.
- Skipping the Rest: We mentioned it, but it’s worth repeating. Resting is essential.
- Not Checking Temp Early: Start checking a few minutes before you think it’s done to avoid overcooking.
- Using Cooking Spray: Aerosol sprays can damage the air fryer basket’s non-stick coating. Use oil in a bottle instead.
Serving Suggestions
A perfectly cooked pork tenderloin pairs well with so many sides. Here are some easy ideas to complete your meal.
- Classic Sides: Mashed potatoes, roasted carrots, or green beans almondine.
- For Lighter Meals: A big garden salad, quinoa salad, or steamed broccoli.
- Quick Sauces: A simple pan sauce made on the stove, applesauce, or a dollop of whole-grain mustard.
Slice the rested tenderloin into ½-inch to 1-inch thick medallions for serving. They look beautiful on the plate and are easy to eat.
Storing and Reheating Leftovers
Leftover pork tenderloin is wonderful for salads and sandwiches. Store it properly to maintain quality.
- Let leftovers cool completely. Then place them in an airtight container in the refrigerator for up to 4 days.
- To reheat, use the air fryer again! Place slices in the basket at 350°F (175°C) for 2-4 minutes, just until warmed through. This helps keep them from drying out. The microwave can make the meat rubbery.
FAQ Section
Do I need to flip the pork tenderloin in the air fryer?
Yes, flipping it halfway through the cooking time is recommended. This ensures even browning and cooking on all sides since the heat source is usually at the top.
Can I cook a frozen pork tenderloin in the air fryer?
It’s not recommended to cook it from frozen. The outside will cook too quickly while the inside remains frozen, leading to uneven results and potential food safety issues. Always thaw it in the refrigerator first.
What’s the best temperature for pork tenderloin in an air fryer?
400°F (200°C) is the ideal temperature. It’s high enough to create a nice sear and cook the meat quickly without drying it out. Some recipes may suggest 375°F for a slightly longer cook if using a sugary glaze that might burn.
Why is my pork tenderloin tough?
Tough pork tenderloin is almost always a result of overcooking. Because it’s such a lean cut, it goes from juicy to dry quickly. Using a meat thermometer to pull it at 145°F and letting it rest is the best way to guarantee tenderness.
Can I put two tenderloins in the air fryer at once?
You can, but make sure they are not touching and there is plenty of space for air flow between them. You may need to add a few extra minutes to the cooking time. It’s better to cook them in separate batches if your air fryer is small.
How do I get a good crust on my pork tenderloin?
The key is ensuring the meat’s surface is very dry before adding oil and seasoning. The high heat of the preheated air fryer will then create that desirable, flavorful crust. Don’t skip the pat-dry step.
Mastering pork tenderloin in the air fryer is a simple way to get a delicious, healthy protein on the table with minimal effort. The speed and consistency of the air fryer makes it an ideal method. Remember the core principles: pat dry, season well, cook at 400°F, check the temperature early, and always let it rest. With this guide, you’ll have a go-to recipe that works every time and leaves you wondering why you didn’t try it sooner. Experiment with different rubs and sides to keep things interesting, and enjoy the compliments when you serve it.
