I’ll give you clear timing for rare through well-done, plus research-backed tips so you can cook with confidence tonight. For most 1.5-inch filets, the short answer is 9–11 minutes at 400°F for medium-rare, with a 5-minute rest. I’ll show you how to adjust the time for thickness, doneness, and even frozen steaks, so you always know exactly how long to cook filet mignon in air fryer for your taste.

What Makes Filet Mignon Different (And Why Time Matters)

Filet mignon is lean, tender, and thick. It has less fat than ribeye, so it cooks fast and can dry out if you overshoot. That’s why I rely on a thermometer and clear timing rules. Research on meat cooking shows lean cuts benefit from high heat for browning and short cook times to protect moisture. This matters even more in an air fryer, which heats fast and circulates hot air for efficient browning.

Time and Temperature Basics You Can Trust

• Best air fryer temp for steak: 400°F (200°C). It gives solid browning without smoking in most models. Some newer units run hot, so you may use 390°F.
• General timing for a 1.5-inch filet:
  • Rare (120–125°F): 7–8 minutes total
  • Medium-rare (130–135°F): 9–11 minutes total
  • Medium (140–145°F): 11–12 minutes total
  • Medium-well (150–155°F): 13–14 minutes total
  • Well-done (160°F+): 15–16 minutes total
• Flip once halfway for even color.
• Rest 5 minutes so juices settle. Expect 3–5°F carryover rise.

Safety note: Food safety guidance recommends 145°F with a 3-minute rest for steak. Use your comfort level and a thermometer. This is key if you ask how long to cook filet mignon in air fryer for guests or kids.

Step-by-Step: From Fridge to Plate

1. Preheat the air fryer to 400°F for 3–5 minutes. Hot air matters.
2. Pat steaks dry. Moisture stops browning.
3. Season and oil lightly. I use 1 tsp high-smoke-point oil per steak, plus salt and pepper. Add garlic powder or crushed pepper if you like.
4. Place steaks in a single layer. Don’t crowd.
5. Cook using the timing chart below, flipping halfway.
6. Check with an instant-read thermometer at the center.
7. Rest 5 minutes on a warm plate. Top with butter or compound butter if you want extra richness.

This simple method works every time, even if it’s your first try figuring out how long to cook filet mignon in air fryer.

Adjusting for Thickness, Doneness, and Starting Temperature

• Thickness rule of thumb:
  • 1.25-inch: subtract 1–2 minutes from the 1.5-inch baseline.
  • 1.75-inch: add 2 minutes.
  • 2-inch: add 3–4 minutes and consider starting at 390°F to prevent over-browning.
• Frozen filet mignon:
  • Preheat to 380–390°F.
  • Cook 6–7 minutes, flip, season, then cook 8–10 minutes more, depending on doneness.
  • Total add-on time: +4–6 minutes versus fresh.
• Fridge-cold vs. room-temp:
  • You can cook straight from the fridge. Room-temp can save 1 minute, but food safety advice suggests keeping meat refrigerated until cooking.

If you keep asking how long to cook filet mignon in air fryer across different sizes, use the thermometer first, then fine-tune next time by 1–2 minutes.

Quick Doneness Targets (Internal Temperatures)

• Rare: 120–125°F (cool red center)
• Medium-rare: 130–135°F (warm red center)
• Medium: 140–145°F (warm pink center)
• Medium-well: 150–155°F (thin pink line)
• Well-done: 160°F+ (no pink)

I pull steaks about 3°F before the target since they rise as they rest. This small step fixes most timing issues people face while learning how long to cook filet mignon in air fryer.

What You Need (Simple Gear, Big Payoff)

• Air fryer with a clean basket
• Instant-read thermometer (a probe thermometer makes it even easier)
• Tongs, paper towels, small bowl for seasoning
• Optional: butcher’s twine to keep shape, a small rack insert to improve airflow

A thermometer is the real hero. Research shows doneness accuracy improves taste and texture. It also removes guessing about how long to cook filet mignon in air fryer in your model.

Pro Tips I Use For Better Browning And Juiciness

• Dry the surface well. Water fights the Maillard reaction (browning).
• Use a tiny bit of oil. Lean filet needs help to sear.
• Don’t overcrowd. Give space for air to move.
• Flip once at the halfway point.
• Rest 5 minutes. Fibers relax, juices stay in.
• Add butter at the end, not the start, to avoid smoke.

These tips are small, but they close the gap between “good” and “wow.” They also shorten your learning curve on how long to cook filet mignon in air fryer for any brand.

Common Mistakes And Easy Fixes

• Steak comes out gray: You didn’t preheat, or the basket was crowded. Preheat, cook fewer at a time, and pat dry.
• Outside browns too fast: Your unit runs hot. Drop to 390°F and add 1–2 minutes.
• Dry steak: You cooked past target temp or didn’t rest. Pull 3°F early and rest 5 minutes.
• Uneven cooking: Filet wasn’t uniform. Tie with twine for a round shape, or rotate the basket at the flip.
• Bland taste: Salt more evenly. Salt draws out moisture that then reabsorbs, improving flavor.

If you’re still unsure how long to cook filet mignon in air fryer for your exact machine, test with a 6–7 minute first side, flip, then check every 2 minutes until you hit your target temperature.

Science Corner: Why Air Fryers Cook Filet So Well

• Fast convection: Air fryers push hot air at high speed. That speeds the Maillard reaction, which needs dry surface heat.
• Lean meat and heat: Filet has little intramuscular fat, so high heat + short time protects tenderness. Research on meat proteins shows prolonged heat tightens fibers and squeezes out juice. Fast cooking helps.
• Carryover cooking: Heat keeps moving to the center after you stop cooking. Expect a small temperature rise, which you can use to your advantage.

Putting this together helps you predict how long to cook filet mignon in air fryer with fewer surprises.

Seasoning Ideas That Actually Work

• Classic: Kosher salt, black pepper, garlic powder
• Bistro: Salt, pepper, crushed peppercorns, thyme, finish with garlic-herb butter
• Bold: Smoked salt, paprika, cayenne, finish with blue cheese butter
• Steakhouse: Montreal steak seasoning, finish with a dab of butter and chopped parsley

Use 1 tsp oil per steak to help spices stick. Another small win for anyone testing how long to cook filet mignon in air fryer while keeping flavor high.

Nutrition And Sourcing Tips

• Filet mignon is high in protein and lower in fat than many cuts. A typical 6-oz portion gives about 44–48 g protein with moderate calories.
• Choose USDA Choice or Prime for better tenderness. Prime has more marbling.
• Look for even thickness. That makes your timing reliable.
• Rested steak tastes juicier, which can help you season less sodium overall.

These choices make your results consistent, so you don’t need to guess how long to cook filet mignon in air fryer each time.

Frequently Asked Questions of how long to cook filet mignon in air fryer

How Do I Cook A 2-Inch Filet In An Air Fryer?

For a 2-inch thick filet at 400°F, plan 13–15 minutes for medium-rare, flipping halfway. Start checking at 12 minutes with a thermometer. Pull 3°F early and rest 5 minutes.

Can I Cook Filet Mignon From Frozen?

Yes. Preheat to 380–390°F. Cook 6–7 minutes, flip and season, then 8–10 minutes more depending on doneness. Add 4–6 minutes total versus fresh.

What Temperature Should I Use For The Best Sear?

Use 400°F for most air fryers. If your model runs hot, use 390°F. This keeps the outside from over-browning before the center reaches your target temp.

Is Medium-Rare Safe?

Guidelines list 145°F with a 3-minute rest for safety. Many people enjoy steak at lower temps, but use your judgment. A thermometer is key.

Do I Need To Bring Steak To Room Temperature First?

No. It’s fine to cook straight from the fridge. It may take about 1 minute longer. Keep handling time short for food safety.
