What Is Fillet Steak?
Fillet steak, also known as tenderloin steak, comes from the smaller end of the tenderloin muscle. This part of the cow does very little work, which is why fillet steak is widely regarded as the most tender cut available. It is naturally lean, with very little intramuscular fat compared to cuts like ribeye or New York strip, which gives it a delicate, buttery texture that melts in the mouth.
Because fillet steak is so lean, it cooks faster than fattier cuts and is more forgiving when it comes to overcooking, provided you keep a close eye on timing and temperature. Common presentations include the classic round fillet, the larger Chateaubriand cut, and the double fillet or “filet mignon” portions that are often wrapped in bacon. Each varies slightly in thickness and cooking time, but all benefit enormously from the even, rapid heat of an air fryer.
Why Cook Fillet Steak in an Air Fryer?
The air fryer has revolutionized home cooking, and premium steaks are no exception. There are several compelling reasons to reach for your air fryer when preparing fillet steak.
First, air fryers produce exceptional crust. The rapid circulation of superheated air around the steak mimics the effect of a high-heat sear, creating a deeply caramelized exterior that locks in juices. Second, air fryers heat up much faster than conventional ovens, which means less time waiting and more time eating. Third, the compact cooking chamber concentrates heat efficiently, reducing overall cooking time and helping you achieve a perfect medium-rare center without drying out the meat.
Additionally, air fryers are incredibly easy to clean compared to cast iron skillets or full-size ovens. Most models have removable baskets that are dishwasher-safe, making post-dinner cleanup a breeze. For anyone who loves steak but does not want to deal with smoke and splatter from a stovetop, the air fryer is an ideal solution.
How Long Fillet Steak in Air Fryer?
The short answer to “How long fillet steak in air fryer?” is typically between 8 and 20 minutes at temperatures ranging from 180°C to 220°C (355°F to 430°F), depending on thickness and doneness preference. However, this is a simplified answer, and understanding the details will help you achieve consistently excellent results.
For a standard 2.5 cm (1 inch) thick fillet steak cooked to medium-rare, expect approximately 10 to 14 minutes in a preheated air fryer set to 200°C (400°F). Thinner cuts of around 1.5 cm may need only 6 to 10 minutes, while thicker Chateaubriand-style cuts exceeding 4 cm could require 18 to 22 minutes with adjusted temperatures. The key is to always preheat your air fryer, pat the steak dry before seasoning, and use a meat thermometer for precision.
Remember that these times are guidelines. Every air fryer model varies slightly in heat output and circulation, so your first cook may need minor adjustments. Keep notes on what works best with your specific appliance, and you will master the technique quickly.
Factors That Affect Cooking Time
Several variables influence exactly how long your fillet steak needs in the air fryer. Understanding these factors allows you to adapt rather than follow a recipe blindly.
- Thickness: This is the single most important factor. A thin filet mignon cooks much faster than a thick Chateaubriand. Always measure your steak before cooking.
- Starting temperature: A steak straight from the refrigerator will take several minutes longer than one that has rested at room temperature for 30 to 45 minutes.
- Desired doneness: Rare requires less time than medium, and medium takes less time than well done. Use the temperature chart below as a reference.
- Air fryer model: Basket-style air fryers and oven-style air fryers distribute heat differently. Compact models may cook faster due to the closer proximity of heating elements.
- Baking or wrapping: Wrapping in bacon or applying a herb crust can add a few minutes to cooking time but adds tremendous flavor.
- Altitude: At higher altitudes, lower air pressure affects boiling points and cooking speeds, potentially requiring slight adjustments.
Air Fryer Fillet Steak Temperature Guide
Internal temperature is the true measure of doneness, not time alone. Here is a detailed breakdown of target internal temperatures for fillet steak at various levels of doneness. Always measure at the thickest point using an instant-read meat thermometer.
| Doneness | Internal Temperature | Visual Cue |
|---|---|---|
| Rare | 50-52°C (120-125°F) | Cool red center |
| Medium Rare | 55-57°C (130-135°F) | Warm pink center |
| Medium | 60-63°C (140-145°F) | Slightly pink center |
| Medium Well | 65-68°C (150-155°F) | Mostly brown, slight pink |
| Well Done | 71-74°C (180-185°F) | Fully brown throughout |
For fillet steak, medium rare is the most popular and recommended doneness. The lean meat remains juicy and flavorful at this temperature, and the texture is at its most tender. Cooking beyond medium can dry out the tenderloin quickly because of its low fat content.
Step-by-Step Guide
Follow this step-by-step process for a perfectly cooked fillet steak in the air fryer every time. This method assumes a standard 2.5 cm thick steak and a 200°C preheated air fryer.
- Remove the steak from the refrigerator 30 to 45 minutes before cooking. Allowing the meat to approach room temperature ensures more even cooking throughout the steak. A cold center is a common cause of uneven results.
- Pat the steak completely dry with paper towels. Moisture on the surface is the enemy of a good crust. Dry surfaces caramelize faster and more evenly in the air fryer.
- Season generously with salt, pepper, and any desired spices. A simple combination of coarse sea salt and freshly cracked black pepper is classic and effective. Apply seasoning on all sides at least 10 minutes before cooking to help draw out surface moisture.
- Preheat the air fryer to 200°C (400°F) for at least 3 to 5 minutes. Preheating ensures the steak begins cooking at the correct temperature from the very first moment. Skipping this step adds unpredictable time and can result in a steamed rather than seared texture.
- Place the steak in the air fryer basket, ensuring it is not touching the walls or each other if cooking multiple steaks. Good airflow around the steak is essential for even cooking.
- Cook for approximately 6 to 8 minutes on the first side. Do not move or flip the steak during this time. Let the air fryer do the work and build that beautiful crust.
- Flip the steak carefully using tongs and cook for another 5 to 8 minutes. The exact time on this side depends on thickness and desired doneness. Use a meat thermometer to check the internal temperature.
- Remove the steak and let it rest for 5 to 8 minutes on a warm plate. Resting allows the juices to redistribute throughout the meat. Cutting into it too early results in a loss of moisture and flavor.
- Slice against the grain and serve immediately. Enjoy your perfectly cooked air fryer fillet steak.
Cooking Times by Thickness
Since thickness is the most significant variable, here is a detailed reference chart. All times assume a preheated air fryer at 200°C (400°F) and target medium-rare doneness. Adjust by adding or subtracting 1 to 2 minutes per 5°C change in temperature.
| Steak Thickness | Approximate Weight | Total Cook Time | Internal Temp Target |
|---|---|---|---|
| 1.5 cm (0.6 inch) | 150-180g | 6-10 minutes | 55-57°C |
| 2.0 cm (0.8 inch) | 180-220g | 8-12 minutes | 55-57°C |
| 2.5 cm (1.0 inch) | 220-270g | 10-14 minutes | 55-57°C |
| 3.0 cm (1.2 inch) | 270-340g | 12-16 minutes | 55-57°C |
| 4.0 cm (1.6 inch) | 340-450g | 16-22 minutes | 55-57°C |
| 5.0 cm (2.0 inch) | 450-550g | 20-25 minutes | 55-57°C |
These times include flipping once halfway through cooking. For thicker cuts, you may want to lower the temperature to 190°C after the initial sear to allow the center to cook through without burning the exterior. This technique, sometimes called the reverse sear when done in an oven, works beautifully in an air fryer as well.
Tips and Best Practices
Elevate your air fryer fillet steak with these expert recommendations.
- Always preheat. This cannot be overstated. A preheated air fryer delivers immediate, consistent heat that is critical for crust formation.
- Use a meat thermometer. Time is only a guideline. Internal temperature is the only reliable indicator of doneness. Invest in a good instant-read thermometer if you do not already own one.
- Do not overcrowd the basket. Cooking multiple steaks? Leave at least 2 cm of space between each piece. Overcrowding blocks airflow and leads to uneven cooking.
- Consider a finishing touch. A knob of herb butter, a drizzle of truffle oil, or a sprinkle of flaky sea salt after resting adds a luxurious finishing layer.
- Lightly oil the steak, not the basket. A thin coating of high smoke-point oil like avocado oil on the steak itself promotes better browning than oiling the basket.
- Experiment with seasoning blends. Garlic powder, smoked paprika, onion powder, and dried thyme create a savory crust that pairs wonderfully with the mild flavor of fillet steak.
- Keep a cooking log. Note the time, temperature, and results for each cook. Over several attempts, you will dial in the perfect settings for your specific air fryer model.
Common Mistakes to Avoid
Even experienced home cooks can stumble when cooking steak in the air fryer. Here are the most frequent errors and how to avoid them.
- Skipping the preheat: Adding a cold steak to a lukewarm basket results in a pale, steamed exterior and uneven cooking. Always preheat for at least 3 to 5 minutes.
- Cooking straight from the fridge: A cold center means the outside will be overcooked before the inside reaches the right temperature. Bring the steak to room temperature first.
- Opening the basket too often: Every time you open the air fryer, you lose significant heat and extend cooking time. Trust the process and resist the urge to peek. Check only when you suspect the steak might be close to done.
- Using wet seasoning: Wet marinades or sauces can create steam instead of a sear. Apply dry seasonings or oil-based pastes for the best crust.
- Cutting too early: Resting is non-negotiable. Cutting into the steak immediately releases juices onto the cutting board instead of keeping them in the meat. Wait at least 5 minutes, ideally 8.
- Ignoring carryover cooking: After removing the steak from the air fryer, the internal temperature will continue to rise by approximately 3 to 5°C. Pull the steak a few degrees below your target and let carryover cooking bring it to the final doneness.
Resting and Serving
Resting your fillet steak after cooking is one of the simplest yet most impactful steps you can take. When the steak is exposed to high heat, the proteins tighten and push moisture toward the center. Cutting too early releases that concentrated juice, leaving you with a drier steak than necessary.
Transfer the cooked fillet steak to a warm plate and loosely tent it with aluminum foil. A warm plate prevents the bottom from cooling too quickly, while the foil retains heat without trapping so much steam that the crust softens. Rest for a minimum of 5 minutes for thinner cuts and up to 10 minutes for thick Chateaubriand portions.
When serving, slice fillet steak against the grain into medallions approximately 1 cm thick. This maximizes tenderness and creates elegant, easy-to-eat pieces. Pair with roasted vegetables, mashed potatoes, or a fresh salad for a complete meal that showcases the star of the plate.

Frequently Asked Questions
Can You Cook Frozen Fillet Steak in the Air Fryer?
Yes, you can cook frozen fillet steak in the air fryer, but you will need to increase the cooking time significantly. Remove the steak from the freezer 15 to 20 minutes before cooking to allow slight thawing. Preheat the air fryer to 180°C (360°F) and cook for approximately 15 to 20 minutes for a 2.5 cm thick steak, flipping halfway through. Use a meat thermometer to verify the internal temperature, as frozen steaks can have unpredictable cooking patterns. For the best results, thawing overnight in the refrigerator is recommended.
What Is the Best Temperature for Fillet Steak in the Air Fryer?
The best temperature for most fillet steaks is 200°C (400°F). This provides a strong sear while cooking the interior evenly. For thicker cuts exceeding 3 cm, consider starting at 220°C for a quick sear and then reducing to 180°C to finish cooking gently. For thinner cuts under 2 cm, 190°C may be sufficient to prevent the exterior from drying out before the center reaches the correct temperature.
Do You Flip Fillet Steak in the Air Fryer?
Yes, flipping is recommended for even cooking. Flip the steak once halfway through the total cooking time using tongs. This ensures both sides develop an equal crust and that heat reaches the center uniformly. For very thick cuts, you may also want to flip twice for more consistent results.
How Do You Know When Fillet Steak Is Done in the Air Fryer?
The most reliable method is using an instant-read meat thermometer inserted into the thickest part of the steak. Refer to the temperature chart earlier in this guide for target internal temperatures based on your preferred doneness. Without a thermometer, press the steak with your finger. A rare steak will feel soft, medium rare will feel springy with slight give, and well done will feel firm throughout. The touch test takes practice, so a thermometer remains the best tool for precision.
Can You Cook Bacon-Wrapped Fillet Steak in the Air Fryer?
Absolutely. Bacon-wrapped fillet steak works wonderfully in the air fryer because the rendered bacon fat bastes the steak as it cooks. Set the temperature to 190°C (375°F) and cook for approximately 14 to 18 minutes depending on thickness, flipping once halfway through. The bacon should be golden and crispy when the steak is done. If the bacon browns too quickly, loosely cover it with foil during the final minutes of cooking.
