Filet mignon, often revered as the pinnacle of tender, flavorful beef, is a cut that demands precision and care in preparation. Known for its buttery texture and mild, succulent flavor, it is a steak that transforms a simple meal into an extraordinary dining experience. Traditionally pan-seared or oven-roasted, filet mignon can also be prepared perfectly in an air fryer-a kitchen marvel that promises even cooking, reduced fat usage, and consistent results. Cooking filet mignon in an air fryer is an art that balances temperature, timing, and technique to ensure the steak remains juicy, tender, and richly flavored.
The temperature at which you cook filet mignon in an air fryer is crucial. Too high, and the exterior may char before the interior reaches the desired doneness; too low, and the steak may dry out or cook unevenly. The optimal temperature for most air fryers is 400°F (204°C). This temperature allows the steak to sear beautifully on the outside, developing a golden-brown crust, while gently cooking the interior to a perfect medium-rare or medium finish.
Some chefs recommend preheating the air fryer for 3-5 minutes to ensure an even sear. Preheating ensures that the air fryer’s circulating hot air immediately begins cooking the steak, reducing the risk of uneven temperature zones that could compromise texture or flavor.

The cooking time depends on the thickness of the filet and the desired doneness. For a standard 1.5-2 inch thick filet mignon cooked at 400°F:
Cooking times may vary slightly depending on air fryer models and the thickness of the steak, so it is essential to monitor closely for accuracy. Turning the steak halfway through cooking ensures even browning and heat distribution.
Determining the doneness of filet mignon requires precision. While timing guides are helpful, the most accurate method is using an instant-read meat thermometer inserted into the thickest part of the steak. The internal temperatures to aim for are:
For those without a thermometer, the touch test can be used: gently press the steak with your fingertip. A rare steak feels soft and yields easily, medium feels springy with slight resistance, and well-done feels firm.
For a classic air fryer filet mignon, you need minimal but high-quality ingredients to highlight the steak’s natural flavor:
These ingredients enhance the flavor without overpowering the delicate taste of the filet.
Adjusting the temperature will affect both the cooking time and the texture of the steak:
Balancing temperature and timing is key; err on the side of slightly lower temperature if you’re cautious about overcooking.
Cooking longer than recommended can dry out the steak, while shorter times may leave it undercooked:
Always consider the thickness of the steak and your preferred doneness, then adjust the time in small increments of 1-2 minutes.
Mistakes happen, but they can often be corrected:
Even with small errors, proper resting and slicing techniques can salvage the experience.
Before air frying, season the filet mignon with salt, pepper, and optional herbs or spices. Allow the meat to reach room temperature for 20-30 minutes to ensure even cooking. Lightly brush or spray the steak with oil to promote browning.
Preheat the air fryer to 400°F (200°C) for most air fryer models. This temperature allows the exterior to sear quickly while keeping the interior tender and juicy.
Cooking time depends on steak thickness and desired doneness. For a 1.5-inch thick filet: rare takes 8-10 minutes, medium-rare 10-12 minutes, medium 12-14 minutes, and medium-well 14-16 minutes. Flip halfway through cooking for even results.
Yes, flipping the steak halfway through the cooking process ensures even browning and consistent doneness on both sides.
Use a meat thermometer: rare (120-125°F / 49-52°C), medium-rare (130-135°F / 54-57°C), medium (140-145°F / 60-63°C), medium-well (150-155°F / 66-68°C). Alternatively, use the finger test method to gauge firmness.
Yes, rest the steak for 5-10 minutes after cooking. This allows the juices to redistribute, keeping the meat moist and flavorful.
Yes, but it requires longer cooking times and may not brown as evenly. For best results, thaw the steak before air frying and follow the standard seasoning and temperature guidelines.
