How To Cook Tenderloin In Air Fryer [FULL GUIDE]

Recommended Equipments:

Cooking a tenderloin in an air fryer can transform a traditionally oven-roasted cut into a fast, succulent, and flavor-packed meal. The tenderloin, known for its delicate texture and mild flavor, is often regarded as a centerpiece of special meals. Achieving the perfect balance of a seared exterior and a juicy, tender interior is the goal, and the air fryer, with its rapid circulation of hot air, offers a convenient and consistent way to reach this culinary milestone. This method reduces cooking time, locks in moisture, and enhances the meat’s natural flavors, all while requiring minimal cleanup. However, air frying meat-particularly a cut as delicate as tenderloin-requires a nuanced understanding of temperature, timing, and preparation techniques to ensure the result is nothing short of perfection.

Optimal Air Fryer Temperature To Cook Tenderloin In Air Fryer

The temperature at which you cook tenderloin in an air fryer is crucial because it determines both the texture and doneness of the meat. For a tender, juicy result, most chefs recommend a range between 375°F and 400°F (190°C-204°C).

• 375°F (190°C): Provides a gentle cook, allowing the meat to heat evenly and remain tender without risk of drying out. This is ideal for thicker cuts.
• 400°F (204°C): Promotes a slightly faster cook and encourages a caramelized, golden-brown exterior. It’s excellent if you want a crispier crust while maintaining a pink, juicy center.

Lower temperatures risk undercooking the interior if the exterior browns too quickly, while higher temperatures can produce a dry, overcooked center. Striking a balance is key-starting at 375°F and finishing at 400°F for a brief period can be a smart strategy for optimal texture.

How Long To Cook Tenderloin In Air Fryer

Cooking time depends on the thickness of the tenderloin and your desired doneness:

• Rare (125°F internal): 12-15 minutes
• Medium-rare (135°F internal): 15-18 minutes
• Medium (145°F internal): 18-20 minutes
• Medium-well (150-155°F internal): 20-22 minutes

These times are calculated for a tenderloin weighing around 1 to 1.5 pounds. Thicker cuts will require additional minutes, whereas smaller portions may cook faster. Air fryers vary slightly in heat distribution, so these times are guidelines; using a meat thermometer is essential for precision.

How To Tell If It Is Done

The most reliable method to check doneness is a meat thermometer:

• Insert into the thickest part of the tenderloin.
• Rare: 125°F (52°C)
• Medium-rare: 135°F (57°C)
• Medium: 145°F (63°C)
• Medium-well: 150-155°F (66-68°C)

Visual and tactile cues also help: the exterior should be golden-brown and slightly firm. Pressing lightly with a finger or tongs will give you an idea of the internal texture: soft for rare, slightly springy for medium-rare, and firm for medium-well.

Ingredients Needed

• 1-1.5 lb beef tenderloin
• 1-2 tablespoons olive oil or melted butter
• 2 teaspoons salt (adjust to taste)
• 1 teaspoon black pepper
• Optional: garlic powder, paprika, fresh herbs (rosemary, thyme)

These simple ingredients enhance the meat’s natural flavors without overwhelming it. Marinating the tenderloin for 30 minutes prior to cooking can further intensify the taste.

How To Cook Tenderloin In Air Fryer

1. Preheat the Air Fryer: 375°F (190°C) for 3-5 minutes.
2. Prepare the Meat: Pat the tenderloin dry with paper towels. Rub olive oil, salt, pepper, and optional seasonings all over.
3. Place in the Air Fryer: Lay the tenderloin in the basket, ensuring it’s not crowded.
4. Cook: Air fry at 375°F for 12-15 minutes, flipping halfway through for even browning.
5. Check Temperature: Use a meat thermometer to confirm doneness.
6. Optional Finish: If desired, increase to 400°F for 2-3 minutes to achieve a crispier crust.
7. Rest: Remove from the air fryer and let it rest for 5-10 minutes. Resting allows juices to redistribute, ensuring a tender bite.

What If I Use A Different Air Fryer Temperature?

• Lower than 375°F: Slower cooking, less browning. May require 5-10 extra minutes, and the exterior may not develop a crisp crust.
• Higher than 400°F: Faster sear, risk of overcooking the interior, especially for medium or medium-rare preferences. You might get a crusty outside but a dry, tough center.

Temperature adjustments are possible but require careful monitoring of the internal temperature.

What If I Use A Different Air Fryer Cooking Time?

• Shorter Time: Undercooked tenderloin, likely rare or unsafe if very brief.
• Longer Time: Risk of overcooked, dry meat. Tenderloin is lean and forgiving only within a precise time frame.

Always pair timing adjustments with internal temperature checks to avoid mistakes.

When Things Go Wrong

• Dry Meat: Likely due to high heat or extended cook time. Solution: cook at a slightly lower temperature, and always rest meat to retain juices.
• Uneven Cooking: Check placement in the basket; avoid crowding, and consider flipping halfway.
• Lack of Crust: Increase temperature briefly at the end or lightly coat with oil/butter before air frying.

Mistakes are often correctable mid-cook with minor adjustments.

Expert Tips

1. Use a thermometer: Precision beats guesswork.
2. Pat meat dry: Moisture prevents browning.
3. Room temperature meat: Let tenderloin sit out 20-30 minutes before cooking for even results.
4. Resting is crucial: Don’t skip it; it’s the secret to juiciness.
5. Experiment with finishing: A brief blast at 400°F or broiling afterward can create a steakhouse-quality crust.

FAQs

What Type Of Tenderloin Is Best For Cooking In An Air Fryer?

Pork or beef tenderloin are both suitable for air fryer cooking. Choose a piece that is uniform in size for even cooking. Pork tenderloin should be trimmed of excess fat and silver skin, while beef tenderloin should be slightly marbled for better flavor and tenderness.

Do I Need To Marinate Or Season The Tenderloin Before Air Frying?

Yes, seasoning or marinating enhances flavor and helps retain moisture. You can use a simple rub of salt, pepper, garlic powder, and herbs, or marinate for a few hours in ingredients like soy sauce, olive oil, and rosemary. Pat the tenderloin dry before cooking to ensure proper browning.

What Temperature Should I Set My Air Fryer For Tenderloin?

Preheat the air fryer to 375°F (190°C) for pork tenderloin and 400°F (204°C) for beef tenderloin. These temperatures allow the exterior to sear while cooking the interior evenly without drying out the meat.

How Long Does It Take To Cook Tenderloin In An Air Fryer?

Cooking time varies depending on the size and type of tenderloin. For pork tenderloin, it generally takes 20-25 minutes, flipping halfway through. Beef tenderloin may take 15-20 minutes for medium-rare, depending on thickness. Always check internal temperature to ensure doneness.

What Is The Ideal Internal Temperature For Tenderloin?

Use a meat thermometer to check doneness. Pork tenderloin should reach 145°F (63°C) with a 3-minute rest, while beef tenderloin should be 130-135°F (54-57°C) for medium-rare and 140-145°F (60-63°C) for medium. This ensures the meat is safe to eat while remaining tender and juicy.

Should I Let The Tenderloin Rest After Air Frying?

Yes, resting is crucial. Allow the tenderloin to rest for 5-10 minutes after cooking. This lets the juices redistribute throughout the meat, preventing dryness and ensuring a tender, flavorful result.

Can I Cook Frozen Tenderloin In An Air Fryer?

It is possible but not recommended for best results. Cooking from frozen may result in uneven cooking, with the exterior overcooked while the interior remains underdone. Thaw the tenderloin in the refrigerator before air frying for consistent tenderness and flavor.
