There’s something satisfying about cooking a steak that turns out exactly how you want—juicy inside, deeply seared outside, and full of flavor. With an air fryer, you can get that steakhouse finish without heating up the kitchen or fussing with a skillet and oven. Filet mignon is already a tender cut, and the air fryer helps it shine.
The timing is consistent, the cleanup is easy, and the results are surprisingly elegant. If you want a special dinner with minimal effort, this is it.
Why This Recipe Works
The air fryer circulates hot air around the steak, which helps develop a beautiful crust while keeping the inside tender. Filet mignon is a lean cut, so it benefits from fast, controlled cooking—no risk of drying it out with long cook times.
Because the air fryer heats quickly and consistently, you’ll get reliable doneness every time.
A quick rest at the end lets the juices settle, so every bite stays moist. And with simple seasoning and a butter baste, the flavor stays clean and classic.
Ingredients
- 2 filet mignon steaks (about 6–8 oz each, 1.5–2 inches thick)
- 1 tablespoon olive oil (or melted ghee)
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder (optional)
- 1 tablespoon unsalted butter per steak
- 1–2 sprigs fresh rosemary or thyme
- 1 small garlic clove, smashed (optional)
- Lemon wedge, for finishing (optional)
How to Make It
- Bring steaks to room temp: Pat the steaks dry with paper towels. Let them sit at room temperature for 20–30 minutes.
This helps them cook more evenly.
- Preheat the air fryer: Set your air fryer to 400°F (200°C) for 5 minutes. A hot basket helps the crust develop.
- Season generously: Rub the steaks with olive oil. Season all sides with salt, pepper, garlic powder, and onion powder if using.
Press the seasoning in so it sticks.
- Add aromatics: Place a small pat of butter, a sprig of rosemary or thyme, and the smashed garlic in the air fryer basket to infuse aroma. If your air fryer basket has large holes, put the aromatics on a small piece of foil to keep them from blowing around.
- Air fry the steaks: Place the steaks in the basket, leaving space between them. Cook for 9–10 minutes for medium-rare, flipping halfway.
For rare, start checking at 7–8 minutes; for medium, 11–12 minutes. Times vary by air fryer model and steak thickness.
- Check doneness with a thermometer: Aim for 120–125°F for rare, 130–135°F for medium-rare, 140–145°F for medium. Remember, temperature will rise another 3–5°F as the steak rests.
- Butter baste to finish: When the steaks come out, top each with 1 tablespoon butter.
Let it melt over the hot surface for extra richness and shine.
- Rest and slice: Transfer steaks to a plate and tent loosely with foil. Rest for 5–7 minutes so the juices redistribute. Slice or serve whole.
- Add a fresh note: Squeeze a tiny bit of lemon over the steaks or finish with flaky salt for a bright, clean finish.
Keeping It Fresh
Leftover filet mignon keeps well if you store it right.
Let it cool, then wrap it tightly or place it in an airtight container. It will stay fresh in the fridge for 3–4 days.
To reheat without overcooking, use the air fryer at 300°F for 3–4 minutes or warm in a skillet over low heat with a touch of butter. Avoid microwaving on high—it can toughen the meat.
Leftover slices are great on salads, in sandwiches, or with eggs for a simple breakfast.
Benefits of This Recipe
- Consistent results: The air fryer helps you hit your target doneness with less guesswork.
- Minimal mess: No splattering oil from pan-searing, and cleanup is quick.
- Fast cook time: From start to finish, dinner is ready in about 25–30 minutes, including preheating and resting.
- Steakhouse flavor at home: A crisp exterior and buttery finish make it feel special without the price tag.
- Flexible seasoning: Keep it classic with salt and pepper or switch it up with herbs and spice blends.
What Not to Do
- Don’t skip the preheat: A cold basket can lead to pale, under-seared steaks.
- Don’t crowd the basket: Air needs to circulate. Cook in batches if needed.
- Don’t cook straight from the fridge: Ice-cold steaks often cook unevenly. Give them that brief rest at room temp.
- Don’t rely on timing alone: Use an instant-read thermometer for accuracy, especially with thick cuts.
- Don’t cut into the steak right away: Resting is what keeps it juicy—those minutes matter.
Variations You Can Try
- Peppercorn crust: Press coarsely cracked black pepper onto the steaks before cooking.
Serve with a quick pan sauce made from warm cream, Dijon, and a splash of brandy.
- Garlic-herb butter: Mix softened butter with chopped parsley, chives, and grated garlic. Chill and slice over the hot steak.
- Smoky rub: Add smoked paprika and a pinch of cayenne to the seasoning for a subtle kick.
- Blue cheese finish: Crumble blue cheese over the steak during the last minute of cooking so it softens without fully melting.
- Bacon-wrapped: Wrap each filet with a strip of bacon and secure with a toothpick. Air fry at 390°F to allow the bacon to crisp without burning, adding 1–2 extra minutes as needed.
FAQ
What temperature should I cook filet mignon in the air fryer?
For a good sear and tender center, 400°F (200°C) is a sweet spot.
If your air fryer runs hot, you can drop to 390°F. Always check with a thermometer for doneness.
How long do I cook it for medium-rare?
For 1.5–2-inch-thick steaks, plan for 9–10 minutes total at 400°F, flipping halfway. Start checking the internal temperature at 8 minutes to avoid overcooking.
Do I need to marinate filet mignon?
No.
Filet is tender and doesn’t need a marinade. Simple seasoning plus butter and herbs is enough. If you want extra flavor, try a compound butter or a quick post-cook sauce.
Can I cook frozen filet mignon in the air fryer?
You can, but it’s not ideal.
The outside may overcook before the center reaches target temperature. If you must, cook at 360°F until thawed in the center, then increase to 400°F to finish, and monitor closely.
Should I oil the steak or the basket?
Oil the steak. A thin coat of oil helps the seasoning adhere and promotes browning.
If your basket tends to stick, a light spray is fine in addition to oiling the meat.
What if my steak is thinner than 1.5 inches?
Reduce the time. For 1-inch steaks, start checking at 6–7 minutes total. The thermometer is your best guide.
Can I cook more than two steaks at once?
Yes, as long as you don’t crowd the basket.
If the steaks touch, they steam instead of sear. Work in batches for the best crust.
How do I keep the steak juicy?
Don’t overcook, rest the steak for at least 5 minutes, and finish with butter. Hitting your target internal temperature and letting the juices redistribute are key.
What sides go well with air fryer filet mignon?
Keep it simple: roasted asparagus, air-fried potatoes, a side salad with lemon vinaigrette, or a creamy mash.
A drizzle of balsamic glaze also pairs nicely.
Can I use this method for other cuts?
Absolutely. Ribeye, New York strip, and sirloin all work well. Adjust time based on thickness and fat content, and always check internal temperature.
In Conclusion
Air fryer filet mignon gives you steakhouse quality with weeknight ease.
With a quick preheat, simple seasoning, and a careful rest, you’ll get a tender center and a flavorful crust every time. Keep a thermometer handy, don’t crowd the basket, and finish with butter and herbs for that polished touch. It’s a reliable, low-fuss way to make a special meal at home—no grill or heavy pan required.
