Air Fryer Filet Mignon

Air Fryer Filet Mignon is one of my favorite ways to prepare a tender, juicy steak without spending much time at the stove. The air fryer cooks the filet quickly and evenly while creating a flavorful crust on the outside and keeping the center succulent. I finish each steak with butter, rosemary, and thyme for a rich, restaurant-style flavor with very little effort.

Why You’ll Love This Recipe

I love this recipe because it turns a premium cut of beef into an impressive dinner without requiring complicated cooking techniques. The high heat of the air fryer helps me develop a nicely browned exterior while maintaining the tender texture that makes filet mignon so special.

I also appreciate how simple the seasoning is. Salt, black pepper, and garlic powder enhance the natural beef flavor rather than covering it up, while butter and fresh herbs add richness at the end. Since the steaks cook in about 12 minutes, I can make this recipe for a special occasion or an easy weeknight dinner.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Filet mignon steaks

Olive oil

Salt

Black pepper

Garlic powder

Unsalted butter

Fresh rosemary

Fresh thyme

I like to choose filet mignon steaks that are similar in thickness so they cook at approximately the same rate. I also use fresh rosemary and thyme whenever possible because their aroma pairs beautifully with the butter and beef.

Directions

I remove the filet mignon steaks from the refrigerator and let them sit at room temperature for about 20–30 minutes. This takes some of the chill off the meat and encourages more even cooking.

I pat the steaks thoroughly dry with paper towels. Removing excess moisture helps the exterior brown better in the air fryer.

I lightly rub each steak with olive oil, then season all sides generously with salt, black pepper, and garlic powder.

I preheat my air fryer to 400°F (200°C) for 3–5 minutes.

I arrange the seasoned steaks in the air fryer basket in a single layer, leaving some space between them so the hot air can circulate.

I air fry the steaks for 5–6 minutes, then carefully flip them.

I place a small piece of unsalted butter on top of each filet and add fresh rosemary and thyme.

I continue air frying for another 4–6 minutes, checking the steaks toward the end of the cooking time. Since steak thickness and air fryer models vary, I prefer checking the internal temperature rather than relying entirely on cooking time.

Once the steaks reach my preferred doneness, I remove them from the air fryer and let them rest for 5–10 minutes. I find that this resting period helps keep the meat juicy when I slice into it.

For the best results, I use an instant-read meat thermometer to monitor doneness. I also keep in mind that the internal temperature can continue to rise slightly while the filet rests.

Variations

Garlic Butter Filet Mignon:

For even more garlic flavor, I mix softened butter with finely minced garlic before placing it on the steaks. I sometimes add a little chopped parsley for extra freshness.

Herb Butter Filet Mignon:

I combine softened butter with chopped rosemary, thyme, and parsley. I place a spoonful over each hot steak after cooking so it slowly melts across the surface.

Pepper-Crusted Filet Mignon:

When I want a stronger steakhouse flavor, I increase the amount of coarsely ground black pepper and press it gently onto the outside of the steaks before air frying.

Spicy Filet Mignon:

For a little heat, I add a pinch of cayenne pepper or crushed red pepper to the seasoning mixture. I keep the amount small so the spice complements rather than overwhelms the filet.

Simple Salt and Pepper Filet:

When I have especially good-quality filet mignon, I sometimes skip the garlic powder and season the steaks with only salt and freshly cracked black pepper. The simple seasoning allows the beef to remain the main flavor.

Storage/Reheating

If I have leftover filet mignon, I let it cool before transferring it to an airtight container. I store it in the refrigerator for up to 3–4 days.

For reheating, I prefer using a relatively low temperature so I don’t overcook the center. I can place the steak in the air fryer at about 350°F (175°C) for a few minutes, checking frequently until warmed through. I can also warm it gently in a covered skillet over low heat with a small amount of butter.

If I know I’ll be reheating leftovers, I avoid slicing the entire steak before storing it. Keeping the filet whole helps it retain more moisture.

FAQs

Can I cook frozen filet mignon in the air fryer?

I prefer thawing filet mignon completely before air frying because it gives me better control over the final doneness and allows the seasoning to adhere evenly. Cooking from thawed also makes it easier to achieve a browned exterior without overcooking parts of the steak.

How do I know when air fryer filet mignon is done?

I check the thickest part of the steak with an instant-read meat thermometer. Since filet mignon can go from perfectly cooked to overdone fairly quickly, I start checking before the estimated cooking time is finished and account for a small temperature increase while the steak rests.

Do I need to flip filet mignon in the air fryer?

I flip the steaks about halfway through cooking. Although an air fryer circulates hot air around the food, I find that flipping helps the steaks cook and brown more evenly on both sides.

Do I have to preheat the air fryer?

I recommend preheating it for this recipe. Starting with a hot air fryer immediately exposes the outside of the filet to high heat, which helps create a better crust while allowing the inside to remain tender.

Why should I rest filet mignon after cooking?

I rest the steaks for about 5–10 minutes before serving because cutting into them immediately can cause more of their juices to run onto the plate. A short resting period gives me a juicier and more enjoyable filet.

Conclusion

Air Fryer Filet Mignon gives me a simple way to prepare an elegant steak dinner with minimal equipment and a short cooking time. The combination of a seasoned crust, tender center, melted butter, rosemary, and thyme creates plenty of steakhouse-style flavor without making the process complicated.

I especially like this recipe when I want something impressive that doesn’t require spending the entire evening in the kitchen. With a quick seasoning, a few minutes in the air fryer, and a proper rest before serving, I can enjoy a tender and flavorful filet mignon right at home.
