Filet mignon in an air fryer cooks faster than most steak lovers anticipate, making a timer essential. If you are wondering how long to cook filet mignon in the air fryer, the short answer is 8 to 14 minutes total, depending on thickness and your target doneness. That range is tight, so a few minutes too long can push a tender steak into dry territory.
This guide gives you exact times, temperatures, and a simple method you can repeat every time. You will also learn how to prep the steak, rest it, and check doneness without cutting it open too early.
How Long To Cook Filet Mignon In The Air Fryer
Air fryers run hot and move air fast. That combo sears the outside while cooking the inside quickly. Filet mignon is lean and tender, so it needs a short cook time and a good rest.
Use this chart as your starting point. Times are for a 1.5-inch thick filet at 400°F (204°C). Always preheat your air fryer for 5 minutes first.
- Rare (120-125°F): 7 to 9 minutes
- Medium rare (130-135°F): 9 to 11 minutes
- Medium (140-145°F): 11 to 13 minutes
- Medium well (150-155°F): 13 to 15 minutes
- Well done (160°F+): 15 to 18 minutes
Flip the steak halfway through the cook time. For a 1-inch filet, subtract about 2 minutes. For a 2-inch filet, add about 2 to 3 minutes.
Why Filet Mignon Cooks So Fast In An Air Fryer
An air fryer is a small convection oven. The fan pushes 400°F air right against the meat. That constant airflow cooks the surface fast and transfers heat into the center quicker than a pan or a big oven.
Filet mignon is also small and lean. It has little fat to insulate the inside, so heat moves through it fast. This is why the window between perfect and overcooked is so narrow.
Best Temperature Setting For Air Fryer Filet Mignon
Set your air fryer to 400°F for the best crust. Some models run hotter or cooler than the dial says, so use an instant-read thermometer to confirm doneness. Never trust the timer alone.
If your air fryer tends to burn the top, drop to 380°F and add 1 to 2 minutes to the total time. You will still get a good sear with less risk of a charred crust.
Step-By-Step Air Fryer Filet Mignon Recipe
Follow these steps in order. The prep matters as much as the cook time.
- Take the filet out of the fridge 30 minutes before cooking. Room-temperature meat cooks more evenly.
- Pat the steak completely dry with paper towels. Moisture steams the meat and blocks browning.
- Rub both sides with a little oil. Use avocado or canola oil, since they handle high heat well.
- Season generously with salt and black pepper. Add garlic powder or rosemary if you like.
- Preheat the air fryer at 400°F for 5 minutes. Do not skip this step.
- Place the filet in the basket. Leave space around it so air can flow. Cook in batches if needed.
- Cook for 5 minutes, then flip. Continue cooking for another 4 to 6 minutes.
- Check the internal temp with a thermometer at the thickest part.
- Pull the steak 5°F below your target. It will rise while resting.
- Rest on a cutting board for 5 to 10 minutes. Tent loosely with foil.
- Slice against the grain and serve.
How To Check Doneness Without Ruining The Steak
Use an instant-read thermometer. Stick it into the side of the filet, right into the center. Avoid hitting the bottom of the basket, which gives a false high reading.
- 125°F: rare
- 135°F: medium rare
- 145°F: medium
- 155°F: medium well
If you do not own a thermometer, press the steak with your finger. A rare steak feels soft and squishy. Medium rare has a little bounce. Medium feels firm but still gives slightly. Well done feels hard.
Common Mistakes To Avoid
Most air fryer filet problems come from a few small errors. Fix these and your steak turns out right every time.
- Not preheating. A cold basket means uneven cooking.
- Crowding the basket. Overlapping steaks steam instead of sear.
- Walking away. Two extra minutes can overcook a thin filet.
- Skipping the rest. Resting lets juices settle back into the meat.
- Using wet marinades. Sugar in marinades burns fast at 400°F.
Tips For The Best Air Fryer Filet Mignon
A few small tweaks make a big difference in texture and flavor.
- Choose steaks of equal thickness so they finish at the same time.
- Trim any silver skin, but leave the fat cap if there is one.
- Add a pat of butter on top after cooking, not before. Butter burns in the air fryer.
- Let the steak rest before slicing. Cutting early drains the juices.
- Slice thick, about half an inch, to keep the meat tender.
Should You Wrap Filet Mignon In Bacon In The Air Fryer
Bacon adds flavor and keeps the lean filet moist. Wrap one slice around the side and secure it with a toothpick. Add 1 to 2 minutes to the cook time, since the bacon needs to crisp.
Check the bacon near the end. If it looks like it is burning, lower the heat to 375°F for the final few minutes.
Can You Cook Frozen Filet Mignon In An Air Fryer
Yes, but it takes longer and the crust suffers. Cook frozen filet at 400°F for 18 to 22 minutes, flipping halfway. The outside may cook before the inside thaws fully, so always verify with a thermometer.
For the best results, thaw the steak in the fridge overnight. Fresh or fully thawed meat gives you a better sear and a more predictable cook time.
What To Serve With Air Fryer Filet Mignon
Keep sides simple so the steak stays the star. Good options include roasted asparagus, garlic green beans, a baked potato, or a light Caesar salad. You can even cook vegetables in the air fryer after the steak rests, using the same basket.
Final Timing Reminders
Write these numbers down and keep them handy. They cover most home air fryer models.
- 1-inch filet, medium rare: 7 to 8 minutes
- 1.5-inch filet, medium rare: 9 to 11 minutes
- 2-inch filet, medium rare: 12 to 14 minutes
- Always flip halfway through
- Always rest 5 to 10 minutes
The exact time depends on your air fryer, the steak thickness, and how cold the meat was when it went in. Start with the lower number, check the temperature, and add time in one-minute bursts. That habit alone will keep your filet mignon tender, juicy, and cooked just the way you like it.
