Why Cook Filets in an Air Fryer?

You might be skeptical about using an air fryer for a premium cut like filet mignon. After all, traditional methods like pan-searing or grilling are the go-to for many steak lovers. However, the air fryer offers a unique set of advantages that make it an incredibly practical option for busy home cooks.

First, the air fryer eliminates the need for a hot, smoky pan on the stovetop. There is no oil splatter, no smoke alarm going off, and no heavy cast-iron skillet to scrub afterward. The entire cooking process happens inside a compact, enclosed basket, which makes cleanup a breeze. If you are cooking for one or two people, the air fryer is also far more energy-efficient than firing up a full-size oven or grill.

Second, the hot air circulation creates a consistent, even cooking environment. This is especially helpful for filet mignon because of its thick, uniform shape. The air fryer sears the exterior quickly while gently cooking the interior, resulting in a steak that is evenly cooked from edge to center. Unlike a pan, you do not have to worry about hot spots or flipping the steak repeatedly.

Finally, the air fryer is incredibly forgiving. Because the temperature is precisely controlled, it is much easier to hit your target doneness compared to other cooking methods. Once you learn how to cook filets in an air fryer, you will find yourself reaching for this countertop appliance again and again. It delivers a beautifully browned crust, a juicy interior, and a perfectly consistent result with minimal effort.

Choosing the Right Filet Mignon

The quality of your steak plays a massive role in the final result. Even the best air fryer technique cannot fix a low-quality cut of meat. When you are at the butcher counter or grocery store, look for filets that are thick, evenly shaped, and well-marbled.

What to Look For

Filet mignon comes from the tenderloin, which is a muscle that does very little work. This means it is naturally extremely tender, but it also means it is lower in fat compared to ribeye or strip steak. Because of the lower fat content, you want to choose a filet that has at least some fine marbling — the thin white streaks of fat running through the meat. This fat will melt during cooking and keep the steak moist.

Thickness matters a lot. Look for filets that are at least 1.5 inches thick. A thicker steak gives you more room for error. A thin filet will cook too quickly in the air fryer and may end up overdone before the outside has a chance to develop a nice crust. If you can find 2-inch-thick filets, even better — they produce the most dramatic and impressive results.

You also want to choose steaks that are roughly uniform in shape. Filets that taper sharply at one end will cook unevenly. Some butchers sell center-cut filets, which are the most uniform and desirable. Finally, always check the color. Fresh filets should have a deep, cherry-red color with no gray or brown spots.

Ingredients You’ll Need

One of the best things about this recipe is the short ingredient list. You do not need any complicated marinades or specialty ingredients to produce a fantastic steak. Here is what you will need:

• Two filet mignon steaks (about 6 to 8 ounces each, at least 1.5 inches thick)
• 1 to 2 tablespoons of high smoke point oil, such as avocado oil or light olive oil
• Coarse kosher salt or sea salt
• Freshly ground black pepper
• Optional: garlic powder, onion powder, smoked paprika, or fresh thyme sprigs
• 1 to 2 tablespoons of unsalted butter (for finishing)

The oil is essential for helping the seasonings stick and for promoting browning. Avocado oil has a high smoke point and a neutral flavor, making it the ideal choice. Olive oil works too, but avoid extra virgin olive oil because it has a lower smoke point and a more pronounced flavor.

Salt is your most important seasoning. Use a coarse kosher salt rather than fine table salt. Coarse salt adheres better to the meat and dissolves more slowly, which helps create a flavorful crust. Freshly cracked black pepper is also essential — skip the pre-ground stuff if you can.

The butter at the end is optional but highly recommended. A small pat of butter melted over the hot steak adds richness and a silky mouthfeel that complements the lean filet perfectly. You can also add a crushed garlic clove and a sprig of rosemary or thyme to the butter for extra aroma.

How to Cook Filets in Air Fryer? Step-by-Step Guide

Now for the main event. This step-by-step process will produce a perfectly cooked filet with a gorgeous crust. Be sure to read through the entire method before starting so you understand the flow.

Step 1: Bring the Steaks to Room Temperature

Take your filets out of the refrigerator about 30 to 45 minutes before cooking. Allowing them to come to room temperature ensures more even cooking. A cold steak straight from the fridge will have a cold center, which makes it harder to achieve that perfect medium-rare while still developing a crust. Pat the steaks dry with paper towels before proceeding. Removing surface moisture is critical for browning.

Step 2: Season Generously

Drizzle a small amount of avocado oil over both sides of each filet and rub it in with your hands. Then, season generously with kosher salt and freshly ground black pepper. Do not be shy — a good crust requires a generous amount of seasoning. If you are using additional spices like garlic powder or smoked paprika, apply them now. Press the seasonings gently into the surface of the meat so they adhere.

Step 3: Preheat Your Air Fryer

Preheating is a crucial step that many people skip. Set your air fryer to 400°F (200°C) and let it run empty for about 3 to 5 minutes. This ensures the basket is hot before the steaks go in, which is essential for immediate searing. If you place cold steaks into a cold air fryer, the heat will gradually rise, and the steaks will end up stewing rather than searing.

Step 4: Place the Filets in the Basket

Once the air fryer is preheated, place the seasoned filets in the basket in a single layer. Do not overcrowd the basket. The steaks need space for hot air to circulate around them. If your air fryer is small, cook the steaks in batches. Leaving at least an inch of space between the steaks ensures even cooking and proper browning.

Step 5: Cook at a High Temperature

Set the air fryer to 400°F (200°C). Cook the filets for about 8 to 10 minutes for a 1.5-inch-thick steak, flipping them halfway through. The exact time depends on your desired doneness and the size of your steaks. For medium-rare, aim for an internal temperature of 130°F to 135°F (54°C to 57°C). If you prefer medium, target 140°F to 145°F (60°C to 63°C). Use a reliable instant-read meat thermometer to check the temperature in the thickest part of the steak.

Step 6: Rest the Steaks

When the filets reach about 5°F below your target temperature, remove them from the air fryer immediately. Place them on a cutting board or plate and loosely tent them with a piece of aluminum foil. Let them rest for 5 to 10 minutes. During this time, the juices redistribute throughout the meat, ensuring every bite is juicy and flavorful. If you skip the resting step, the juices will run out when you cut into the steak, leaving it dry.

Step 7: Add a Butter Finish

While the steaks are resting, you can melt a small pat of butter on top of each filet. The residual heat will melt the butter and create a rich, glossy finish. This is a simple restaurant trick that elevates the flavor significantly. Serve the filets immediately after resting.

Air Fryer Filet Temperature and Timing Chart

The table below provides approximate cooking times for filet mignon in an air fryer at 400°F (200°C). Please note that these times are for steaks that are about 1.5 inches thick and at room temperature before cooking. Your specific air fryer model may vary slightly, so always use a meat thermometer to confirm doneness.

Remember that the internal temperature will continue to rise by about 5°F during the resting period. This is called carryover cooking. To hit your exact target, remove the steaks from the air fryer when they are about 5°F below the desired final temperature.

Best Seasonings for Air Fryer Filets

Filet mignon has a naturally mild, delicate flavor. Because it is so tender, you do not want to overpower it with heavy marinades or strong sauces. A simple, classic seasoning approach is almost always the best choice. However, you can still get creative with a few complementary flavors.

Here are some of the best seasoning combinations:

• Classic Salt and Pepper: The standard steakhouse approach. Use generous amounts of coarse kosher salt and freshly cracked black pepper. This highlights the natural flavor of the beef.
• Garlic Herb Butter: Mix softened butter with minced garlic, chopped fresh rosemary, and thyme. Spread this over the hot steak after cooking for a luxurious finish.
• Smoky Spice Rub: Combine smoked paprika, garlic powder, onion powder, and a pinch of cayenne pepper. This adds a subtle smokiness without overwhelming the steak.
• Coffee Rub: A small amount of finely ground coffee mixed with brown sugar, salt, and pepper creates an earthy, slightly sweet crust. This works particularly well with the air fryer’s hot air circulation.
• Steak Seasoning: A store-bought steak seasoning blend, like Montreal steak seasoning, is perfectly fine. Just check the salt content, so you do not over-salt the meat.

When using wet ingredients like soy sauce or Worcestershire sauce, keep in mind that they can cause the steak to steam rather than sear. If you want a wet marinade, be sure to pat the steaks dry thoroughly before placing them in the air fryer. For the best crust, a dry rub is always preferable.

Tips for Juicy, Tender Filets

Cooking filet mignon in an air fryer is straightforward, but a few extra tips can take your results from good to exceptional. Pay attention to these details, and you will consistently produce juicy, tender steaks.

• Dry the surface thoroughly: Moisture is the enemy of browning. Use paper towels to pat the steaks completely dry before adding oil and seasonings.
• Do not skip preheating: A hot basket is essential for creating an immediate sear. Without it, the surface of the steak will not brown properly.
• Use a meat thermometer: Guessing doneness is a risky game. A reliable instant-read thermometer removes all the guesswork and ensures you never over- or under-cook your filets.
• Flip halfway through: Flipping the steaks halfway through cooking ensures even browning on both sides. It also promotes even cooking throughout the thickness of the steak.
• Let them rest: This is non-negotiable. Resting allows the muscle fibers to relax and the juices to redistribute. Cutting into a steak immediately will result in a dry, flavorless piece of meat.
• Consider salting ahead of time: If you have the time, salt the steaks and leave them uncovered in the refrigerator for one hour before cooking. This dry-brine technique draws out moisture, seasons the meat deeply, and creates an even better crust.

Common Mistakes to Avoid

Even experienced home cooks can fall into a few traps when making air fryer steaks. Here are the most common mistakes and how to avoid them.

Using a Cold Steak

Placing a steak straight from the refrigerator into the air fryer is a recipe for uneven cooking. The center will still be cold while the outside is already overcooked. Always let your steaks sit at room temperature for at least 30 minutes before cooking.

Overcrowding the Basket

If you place two large filets right next to each other with no space in between, the hot air cannot circulate properly. This results in steaming rather than searing. If your air fryer is small, cook the steaks in batches and keep the cooked steaks warm in a low oven while you finish the others.

Not Preheating

Skipping the preheat step is one of the most common mistakes. Without a hot basket, the steak will not get that initial blast of heat it needs to form a crust. This leads to a gray, unappetizing exterior.

Overcooking the Steak

Filet mignon is a lean cut, which means it can become dry and tough if overcooked. It is better to err on the side of undercooking, as the carryover heat will bring it to the perfect temperature during the resting period.
