How Long to Cook Pork Tenderloin in a Ninja Air Fryer?
Cooking pork tenderloin in a Ninja Air Fryer is a fast and convenient way to achieve a juicy, tender, and perfectly cooked meal. Generally, you should air fry pork tenderloin for 15-20 minutes at 375°F (190°C), flipping halfway through, until it reaches an internal temperature of 145°F (63°C).
The Air Fryer Advantage for Pork Tenderloin
Why choose an air fryer for pork tenderloin over other cooking methods? The air fryer’s rapid circulation of hot air creates a crispy exterior while locking in moisture, resulting in a flavorful and tender interior. It’s also faster and requires less oil than traditional oven roasting. This makes it an ideal weeknight dinner option.
Preparing Your Pork Tenderloin
Proper preparation is crucial for a successful air fryer pork tenderloin. Here’s what you need to do:
- Trim the Silver Skin: Remove any silverskin – the thin, silvery membrane on the surface of the tenderloin – as it can become tough during cooking.
- Pat Dry: Thoroughly pat the pork tenderloin dry with paper towels. This promotes better browning.
- Season Generously: Don’t be shy with the seasoning! A simple blend of salt, pepper, garlic powder, and paprika works well. Consider adding herbs like rosemary or thyme, or a pre-made spice rub.
- Optional: Marinate: Marinating for at least 30 minutes (or up to overnight) can enhance the flavor and tenderness.
The Air Frying Process: A Step-by-Step Guide
Follow these steps for perfectly air-fried pork tenderloin:
- Preheat Your Air Fryer: Preheat your Ninja Air Fryer to 375°F (190°C) for 5 minutes.
- Prepare the Tenderloin: Lightly brush the pork tenderloin with olive oil or cooking spray to help it brown.
- Place in the Air Fryer Basket: Place the tenderloin in the air fryer basket, ensuring it isn’t overcrowded. If you have a small air fryer, you may need to cut the tenderloin in half.
- Cook: Air fry for 15-20 minutes, flipping halfway through (around the 7-10 minute mark).
- Check the Internal Temperature: Use a meat thermometer to check the internal temperature. The USDA recommends an internal temperature of 145°F (63°C) for pork tenderloin, followed by a 3-minute rest.
- Rest Before Slicing: Let the pork tenderloin rest for at least 3 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
Temperature and Time Chart
Here’s a general guideline for air frying pork tenderloin in a Ninja Air Fryer:
| Doneness | Internal Temperature | Air Frying Time (approx.) |
|---|---|---|
| Medium Rare | 145°F (63°C) | 15-18 minutes |
| Medium | 150°F (66°C) | 18-20 minutes |

Frequently Asked Questions (FAQs)
Can I use frozen pork tenderloin in the air fryer?
While it’s best to use thawed pork tenderloin for optimal results, you can cook it from frozen. However, it will take significantly longer (approximately 30-40 minutes) and the texture may not be as tender. It’s also essential to use a meat thermometer to ensure it reaches a safe internal temperature.
What temperature should my pork tenderloin be to be considered safe to eat?
The USDA recommends an internal temperature of 145°F (63°C) for pork tenderloin, followed by a 3-minute rest time. This allows the temperature to equilibrate and ensures that any potentially harmful bacteria are eliminated.
How do I know when my pork tenderloin is done?
The most reliable way to determine doneness is to use a meat thermometer. Insert the thermometer into the thickest part of the tenderloin, avoiding bone if present. Once it reaches 145°F (63°C), it’s ready to rest.
Can I air fry two pork tenderloins at the same time?
You can air fry two pork tenderloins at the same time, but make sure they are not overcrowded. If they don’t fit comfortably in a single layer, cook them in batches. Overcrowding can lead to uneven cooking and longer cooking times.
What if my pork tenderloin is too thick for the air fryer?
If your pork tenderloin is exceptionally thick, consider butterflying it (slicing it lengthwise and opening it up like a book) to reduce the thickness and ensure even cooking. You may also need to adjust the cooking time accordingly.
Why is my pork tenderloin dry?
Several factors can contribute to dry pork tenderloin. Overcooking is the most common cause. Other reasons include not letting it rest before slicing, not using enough seasoning, or not trimming the silver skin properly.
Can I use a dry rub instead of a marinade?
Yes, you can use a dry rub instead of a marinade. Apply the rub generously to the pork tenderloin at least 30 minutes before cooking, or even overnight for more intense flavor.
Is it necessary to flip the pork tenderloin halfway through cooking?
Flipping the pork tenderloin halfway through cooking helps to ensure that it cooks evenly on all sides, resulting in a more uniform color and texture.
How long should I let the pork tenderloin rest before slicing?
Letting the pork tenderloin rest for at least 3 minutes is crucial for tenderness and juiciness. This allows the juices to redistribute throughout the meat. Some chefs even recommend a 5-10 minute rest for larger cuts.
What are some good side dishes to serve with air-fried pork tenderloin?
Pork tenderloin pairs well with a variety of side dishes, including roasted vegetables (broccoli, Brussels sprouts, carrots), mashed potatoes or sweet potatoes, rice or quinoa, and salad.
Can I reheat leftover pork tenderloin in the air fryer?
Yes, you can reheat leftover pork tenderloin in the air fryer. Preheat the air fryer to 350°F (175°C) and air fry for 3-5 minutes, or until heated through. Be careful not to overcook it, as this can make it dry.
What are some variations on this recipe?
Consider wrapping the pork tenderloin in bacon before air frying for added flavor and moisture. You can also stuff it with ingredients like spinach and feta cheese or sun-dried tomatoes and mozzarella for a more elaborate dish.
