Filet mignon always feels like a special-occasion steak. It’s incredibly tender, lean, and delicate in flavor — the kind of cut that doesn’t need much beyond simple seasoning and careful cooking. Making Air Fryer Filet Mignon might sound surprising at first, but it’s actually one of the easiest ways to get a beautifully cooked steak with a gently crisp exterior and a buttery-soft center.
What I love most about cooking filet in the air fryer is how approachable it makes something that usually feels fancy or restaurant-only. No splattering pans, no smoke alarms, no complicated techniques — just steady heat and good timing. The result is a steak that feels elegant but is completely doable at home, even on a quiet evening when you just want to treat yourself.
This is one of those meals that turns dinner into a moment.
Why Filet Mignon Works in the Air Fryer
Filet mignon is cut from the tenderloin, which means it’s naturally tender and low in fat. Because it’s lean, it cooks quickly and benefits from high heat that creates a light crust without overcooking the inside. The air fryer’s circulating hot air helps brown the outside while keeping the interior juicy and tender.
Since filet is usually thick and round, it holds its shape well and cooks evenly in the air fryer basket.
Ingredients
- 2 filet mignon steaks (about 1½–2 inches thick)
- 1 tablespoon olive oil
- Salt, to taste
- Freshly ground black pepper, to taste
- ½ teaspoon garlic powder (optional)
- 2 tablespoons butter
- 1 clove garlic, smashed
- 1 sprig fresh rosemary or thyme (optional)
Optional for serving
- Chopped fresh parsley
- Flaky sea salt
Preparing the Steaks
Take the filets out of the refrigerator about 30 minutes before cooking. Letting them sit at room temperature helps them cook more evenly.
Pat the steaks dry thoroughly with paper towels. This step helps achieve better browning. Rub them lightly with olive oil, then season generously with salt and freshly ground black pepper on all sides. Because filet has a mild flavor, seasoning is important to bring out its best.
Step-by-Step Instructions
- Remove steaks from the refrigerator 30 minutes before cooking.
- Pat dry with paper towels.
- Rub with olive oil and season well with salt and pepper.
- Preheat the air fryer to 400°F (204°C) for about 5 minutes.
- Place the filets in the air fryer basket in a single layer, leaving space around each one.
- Cook for 6 minutes, then flip the steaks.
- Continue cooking for another 4–7 minutes depending on thickness and desired doneness.
- Check the internal temperature with a meat thermometer.
- While the steaks rest, melt butter in a small pan with smashed garlic and herbs for 1–2 minutes.
- Remove steaks from the air fryer and let rest for 5–10 minutes.
- Spoon the warm garlic herb butter over the steaks before serving.
Doneness Guide
Because filet mignon is so lean, it’s best enjoyed at medium-rare or medium to maintain tenderness.
- Rare: 125°F (remove at 120°F)
- Medium-rare: 135°F (remove at 130°F)
- Medium: 145°F (remove at 140°F)
The temperature will rise slightly during resting, so pulling the steaks a few degrees early helps prevent overcooking.
The Importance of Resting
Resting filet mignon is especially important. The muscle fibers relax and reabsorb juices as the steak sits. If cut too soon, those flavorful juices spill out instead of staying in the meat.
I like to tent the steaks loosely with foil while they rest. Adding butter during this time gives the surface a glossy finish and extra richness.
Flavor Variations
For a steakhouse feel, sprinkle a pinch of flaky sea salt just before serving.
A light dusting of smoked paprika adds subtle warmth without overpowering the delicate flavor.
A drizzle of balsamic reduction can add a gentle sweet-tangy contrast.
Filet mignon doesn’t need heavy marinades or bold sauces — simple accents work best.
Serving Ideas
Air Fryer Filet Mignon pairs beautifully with mashed potatoes, roasted asparagus, or sautéed mushrooms. For a lighter plate, serve it with a crisp arugula salad dressed with lemon and olive oil.
It’s also lovely sliced and served over creamy risotto or alongside roasted root vegetables for a comforting but elegant meal.
Storage and Reheating
If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in the air fryer at 325°F for 2–3 minutes. Be careful not to overheat, as filet can dry out quickly.
Thin slices of leftover filet are excellent served cold over salads or tucked into sandwiches.
Final Thoughts
Air Fryer Filet Mignon brings a touch of elegance into everyday cooking without adding stress. It’s tender, flavorful, and surprisingly simple to prepare with just a few ingredients and careful timing. For me, this recipe is about slowing down for a meal that feels special — not because it’s complicated, but because it’s cooked with care and enjoyed fully.
