If you’re wondering exactly how long cook filet mignon in air fryer, you’re in the right place. A filet mignon cooks rapidly in the air fryer, requiring precise timing to achieve a beautiful sear and tender interior. This method delivers a fantastic steak with minimal effort and easy cleanup.
We will cover everything from preparation to perfect doneness. You’ll get clear timings, temperature guides, and pro tips.
Let’s get started on cooking your best air fryer steak.
How Long Cook Filet Mignon In Air Fryer
The core cooking time for filet mignon in an air fryer ranges from 8 to 14 minutes. The exact time depends on your desired doneness and the thickness of your steak. For a standard 1-inch thick filet, here is a reliable guideline.
- Rare (120-125°F internal): 8-9 minutes
- Medium Rare (130-135°F internal): 9-11 minutes
- Medium (140-145°F internal): 11-13 minutes
- Medium Well (150-155°F internal): 13-14 minutes
Always use a meat thermometer to check the internal temperature for the most accurate results. Remember that steaks will continue to cook slightly (a process called carryover cooking) for a few minutes after removed from the air fryer.
Essential Factors That Influence Cooking Time
Several key variables affect how long your filet mignon needs in the air fryer. Understanding these will help you adjust the basic timings for perfect results every time.
Steak Thickness
This is the most important factor. A thin 3/4-inch steak will cook much faster than a thick 2-inch steak. Always measure the thickness at its center. You may need to add 2-3 minutes per extra 1/2 inch of thickness.
Air Fryer Model and Power
Not all air fryers heat the same. Basket-style models with powerful fans may cook faster than oven-style ones. It’s best to start checking the temperature a minute or two before the recommended time ends, especially the first time you use your specific appliance.
Starting Temperature of the Steak
For even cooking, take your filet mignon out of the refrigerator about 30 minutes before cooking. Letting it come closer to room temperature helps it cook more evenly and prevents a cold center.
Desired Level of Doneness
Your personal preference for doneness directly sets the timer. Use the temperature guide above as your primary reference, not just a fixed number of minutes.
Step By Step Guide To Cooking Filet Mignon In The Air Fryer
Follow these simple steps for a perfectly cooked filet mignon with a great crust and juicy interior.
- Prepare the Steaks: Pat the filets completely dry with paper towels. This is crucial for getting a good sear. Season generously on all sides with kosher salt and freshly ground black pepper. You can also add other dry seasonings like garlic powder at this stage.
- Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) for about 3-5 minutes. Preheating ensures immediate searing and more consistent cooking.
- Arrange in the Basket: Place the seasoned steaks in the air fryer basket in a single layer. Make sure they are not touching to allow for proper air circulation. For extra flavor, you can add a small pat of butter or a sprig of thyme on top of each steak.
- Cook to Your Preference: Air fry at 400°F. For a 1-inch filet, cook for 9-11 minutes for medium-rare, flipping halfway through the cooking time. Use the timing chart above to adjust for your preferred doneness.
- Check the Temperature: In the final minute of cooking, insert an instant-read meat thermometer into the thickest part of the steak. Refer to the doneness temperatures to see if it’s ready.
- Rest the Steaks: Once cooked, transfer the filets to a cutting board or plate. Tent loosely with foil and let them rest for at least 5 minutes. This allows the juices to redistribute throughout the meat, ensuring a moist and flavorful steak.
- Serve: Serve your air fryer filet mignon immediately after resting. Add a finishing salt or a compound butter if desired.
Choosing The Right Filet Mignon For The Air Fryer
Starting with a good quality steak makes all the difference. Here’s what to look for.
- Thickness: Aim for steaks that are at least 1 inch thick. Thicker cuts (1.5 to 2 inches) are excellent for the air fryer as they develop a nice crust while staying juicy inside.
- Grade: USDA Prime or Choice grades have better marbling (intramuscular fat), which translates to more flavor and tenderness. Select grade can be leaner and may dry out more easily if overcooked.
- Uniformity: Try to select steaks that are even in thickness throughout. This promotes even cooking without one part being over or underdone.
- Preparation: You can buy pre-cut filets or cut them yourself from a whole beef tenderloin. If trimming yourself, remove the silverskin, which is a tough connective tissue that won’t render down.
Seasoning And Marinade Ideas
While a classic salt and pepper crust is timeless, you can easily customize the flavor of your air fryer filet mignon.
Simple Dry Rubs
A dry rub creates a flavorful crust. Combine these ingredients and press them onto the steak before cooking.
- Classic Steakhouse: Kosher salt, black pepper, garlic powder, and a touch of onion powder.
- Herb Crusted: Salt, pepper, dried rosemary, dried thyme, and a little dried parsley.
- Spicy Coffee Rub: Finely ground coffee, brown sugar, smoked paprika, chili powder, salt, and pepper.
Wet Marinades and Finishes
Because filet mignon is lean, avoid highly acidic marinades for long periods as they can toughen the meat. Instead, use these as brief marinades (30-60 minutes) or as a finishing glaze.
- Balsamic Herb: Whisk together balsamic vinegar, olive oil, minced garlic, and fresh herbs.
- Garlic Butter Baste: Melt butter with crushed garlic and spoon it over the steak during the last minute of cooking or after it rests.
- Mustard Cream: A simple sauce of Dijon mustard, a splash of cream, and pan juices makes a great topping.
Common Mistakes To Avoid
Avoid these pitfalls to ensure your air fryer filet mignon turns out perfectly.
- Not Drying the Steak: A wet surface steams instead of sears. Always pat the steak thoroughly dry with paper towels.
- Skipping the Preheat: Putting steak into a cold air fryer can lead to uneven cooking and a lack of sear.
- Overcrowding the Basket: If steaks are touching, the hot air cannot circulate properly, resulting in uneven cooking. Cook in batches if necessary.
- Not Using a Thermometer: Guessing doneness by time alone is unreliable. An instant-read thermometer is the only way to guarantee accuracy.
- Skipping the Rest: Cutting into the steak immediately after cooking causes all the flavorful juices to run out onto the plate. Let it rest for at least 5 minutes.
- Using Non-Stick Spray in the Basket: Many aerosol sprays can damage the air fryer basket’s coating over time. Instead, use a light brush of oil on the steak itself or use an oil mister.
Tips For The Best Results
These expert tips will elevate your air fryer filet mignon from good to great.
- For an exceptional crust, after patting dry, lightly coat the steak with a high-smoke-point oil like avocado oil or refined olive oil before seasoning.
- Add aromatic to the basket. Place a few sprigs of fresh thyme, rosemary, or sliced garlic in the basket next to the steak for infused flavor.
- If your steak has a fat cap, you can score it lightly with a knife to prevent curling during cooking.
- After resting, slice the filet mignon against the grain. While filet is very tender, this technique still ensures the most pleasant texture.
- Let your air fryer cool down and clean it after cooking steak to prevent smoke from residual grease during your next use.
Serving Suggestions And Side Dishes
A perfect filet mignon deserves complementary sides. Here are some classic and easy options.
- Potatoes: Air fryer roasted potatoes, creamy mashed potatoes, or a crispy potato galette.
- Vegetables: Air-fried asparagus, roasted mushrooms, creamed spinach, or a simple green salad with a tangy vinaigrette.
- Sauces: A pat of compound butter (like blue cheese or herb butter), a red wine reduction, or a classic peppercorn sauce.
- Bread: A warm, crusty dinner roll to soak up any juices or sauce.
Frequently Asked Questions
Can I cook frozen filet mignon in the air fryer?
Yes, you can cook frozen filet mignon in the air fryer. You will need to add significant cooking time, typically 5-8 minutes extra. It is best to use a lower temperature (around 350°F) for the first half of the cooking time to ensure the center thaws and cooks through, then increase to 400°F to finish the sear. Always use a meat thermometer to verify the internal temperature.
What is the best temperature to air fry filet mignon?
The best temperature for air frying filet mignon is 400°F (200°C). This high heat is necessary to create a flavorful, browned crust (the Maillard reaction) on the outside while keeping the inside tender and juicy. Cooking at to low of a temperature can result in a gray, steamed steak without a good sear.
How do I get a good sear on my steak in the air fryer?
To get a good sear, ensure the steak surface is very dry, lightly coat it with oil, and preheat the air fryer. The high heat and rapid air circulation will create a browned crust. For an even better sear, some cooks finish the steak in a very hot cast iron skillet for 30-60 seconds per side after air frying, though this is not strictly necessary.
Why is my air fryer filet mignon tough?
Tough filet mignon is usually a result of overcooking. Because it is a very lean cut, it can become dry and chewy if cooked past medium doneness. Using a meat thermometer to avoid overcooking and allowing the steak to rest properly are the two best ways to ensure tenderness. Also, make sure you are not using a highly acidic marinade for too long.
Can I cook multiple steaks at once in the air fryer?
You can cook multiple steaks at once, provided they fit in a single layer without touching. Overcrowding will lead to uneven cooking as the air cannot circulate freely. If your steaks are large or your air fryer basket is small, it is better to cook them in separate batches. You can keep the first batch warm by tenting with foil while the second batch cooks.
