Air Fryer Eye Fillet Steak

Eye fillet steak takes about 10–11 minutes at 400°F (205°C) in an air fryer for medium-rare, although steak thickness and air-fryer model can change the timing. An instant-read thermometer is more reliable than the timer for this lean, tender cut. Here’s how to prepare, cook, and rest individual fillets, including culinary doneness targets.

What Eye Fillet Steak Is

Eye fillet is beef tenderloin, the tender muscle that supplies steaks commonly sold as filet mignon. This method is for individual, boneless tenderloin steaks, not a whole tenderloin roast.

Eye fillet is not eye of round. Despite the similar names, eye of round comes from a harder-working muscle and is considerably less tender. Substituting it in a fillet recipe will not produce the same texture, especially if it is thinly sliced.

Because eye fillet has relatively little fat, it benefits from careful temperature control. The air fryer can cook it evenly with little hands-on work, but leaving it in for extra browning after the center is ready can make an expensive steak dry.

How to Cook Eye Fillet Steak in an Air Fryer

For two servings, you’ll need:

2 eye fillet steaks, also sold as filet mignon, about 8 ounces each
Olive oil, enough to coat the surfaces lightly
Salt and freshly ground black pepper, to taste
Garlic-herb butter, optional, for serving

Two 8-ounce steaks are a common starting quantity. When matching steaks to your chosen recipe, confirm their weight on the package label and compare their thickness as well.

Have an instant-read meat thermometer, paper towels, kitchen tongs, and a clean serving plate ready.

Step 1: Thaw, Dry, and Season the Steaks

Start with fully thawed steaks. If they are frozen, thaw them in the refrigerator first. This method’s cooking times are not intended for steaks cooked directly from frozen.
Pat the tops, bottoms, and sides dry with paper towels. Surface moisture must evaporate before the meat can brown.
Rub the steaks with olive oil, leaving a thin film rather than a dripping coating. Season all exposed surfaces with salt and pepper.

There is no need to leave the steaks on the counter until they reach room temperature. Keeping their starting conditions consistent makes it easier to learn how quickly your particular air fryer cooks them.

Step 2: Preheat and Choose Your Doneness

Set the air fryer to Air Fry at 400°F (205°C) and preheat the basket. Use cooking times for eye fillet, not ribeye, even when the preheat setting is the same.
Use the setting recommended for your air-fryer model if it differs from Air Fry at 400°F (205°C). For a Ninja Foodi without a preheat button, a manual preheat of at least 5 minutes is a practical approach, provided your model’s instructions permit preheating empty.

Choose your intended endpoint before cooking. The following are common starting times for thawed fillets air-fried at 400°F; they are total cooking times, not times per side.

Food-safety distinction: USDA guidance for whole beef steaks is an internal temperature of at least 145°F before removal from the heat, followed by at least 3 minutes of resting. The lower culinary targets in this table do not meet that recommendation.

Doneness	Approximate Total Air-Frying Time	Common Culinary Thermometer Target
Rare	9–10 minutes	120°F
Medium-rare	10–11 minutes	130°F
Medium	11–12 minutes	140°F
Medium-well	11.5–13 minutes	150°F
Well-done	About 14 minutes	160°F

These doneness labels are approximate. Air-fryer design and starting temperature change how long it takes to reach them.

Step 3: Air-Fry and Turn the Steaks

Place the steaks in the hot basket in a single layer, leaving space between them. Do not stack them or wedge them tightly against one another.
Air-fry, turning the steaks around halfway through the estimated cooking time.
Close the drawer promptly after turning so the air fryer can recover its heat.

I use a pair of silicone-tipped kitchen tongs here to protect the basket’s coating.

Avoid repeatedly opening the drawer just to inspect the color. A browned surface cannot tell you whether the center has reached your chosen endpoint.

Step 4: Check the Center Before the Timer Finishes

Begin checking 1–2 minutes before the expected finish.
Insert the thermometer from the side so its sensing tip reaches the center of the thickest part. Avoid stopping near the hot surface, which can give a misleadingly high reading.
Check each steak separately. If one is ready before the other, remove it rather than keeping both in the basket.
To meet USDA guidance, cook each steak to at least 145°F before removing it. Do not rely on resting to bring an undercooked center up to that minimum.

The internal temperature can rise about 3–5°F during resting, and sometimes more, depending on thickness and cooking conditions. That carryover is another reason to check early rather than adding time automatically.

Keep the thermometer’s probe clean between checks, especially after probing meat that has not yet reached its endpoint.

Step 5: Rest and Serve

Use clean tongs to transfer the cooked steaks to a clean plate.
Rest for 3–5 minutes before cutting. A final thermometer reading after the 3–5-minute rest can show how much carryover occurred.
Add garlic-herb butter, if using, then serve the fillets whole or slice across the grain.

A loose foil tent is optional. Do not wrap the steaks tightly if you want to preserve the surface browning; trapped steam softens it.

Serve with vegetables, a salad, or potatoes prepared separately so the steak can come out as soon as it is ready.

Adjusting for Steak Thickness and Air Fryer Size

Steak thickness is more useful than steak weight when adjusting cooking time.

Two fillets with identical package weights can have different shapes: one might be a tall medallion, while another is wider and flatter. Their centers will not heat at the same rate.

Thick and Thin Fillets

A thick fillet needs more time for heat to reach its center. A thinner steak can pass its intended doneness before the outside develops much color.

Choose similarly thick steaks when possible. If they differ, treat them as separate pieces rather than expecting a shared timer to finish both correctly.

Do not add a fixed amount of time just because a steak looks large. Starting temperature and position in the basket also matter. Temperature checks are especially important when cooking fillets that differ substantially from those used in a recipe.

Small and Dual-Basket Air Fryers

Basket capacity is not the same as usable steak-cooking space. A basket that technically holds several fillets may not leave enough room for air to circulate around them.

If the steaks cannot sit comfortably apart, cook in batches. Arrange each batch on a clean serving plate and serve promptly after resting rather than holding finished fillets in the hot air fryer.

With a dual-basket model, check the steaks in each drawer independently. Matching settings do not guarantee matching results when the drawers contain different amounts of food. Synchronization features coordinate timers; they do not measure the temperature inside the meat.

Storing and Reheating Leftover Eye Fillet

Refrigerating Leftovers

Refrigerate leftover steak in a shallow, airtight container within 2 hours of cooking, or within 1 hour if the surrounding temperature is above 90°F.

Do not leave it on the counter waiting for it to cool completely. Warm leftovers can go into the refrigerator; prompt chilling matters more than reaching room temperature first.

Keep refrigerated cooked steak for 3–4 days. An airtight container limits drying better than loosely covering the plate, and storing the steak whole rather than pre-slicing it exposes less meat to the air.

Reheating Without Excessive Drying

Reheating will cook the steak further, so do not expect a reheated fillet to retain the same pink center as when it was freshly cooked.

For a moist reheating method:

Slice the steak and place it in a skillet with enough broth or water to moisten the bottom of the pan.
Cover and warm over medium-low heat.
Check that the thickest pieces reach 165°F, then serve promptly.

The covered pan helps limit moisture loss. It will not recreate the original crust, but it is easier to control than continuing to blast a lean leftover fillet with high heat.

Checking the Result and Preventing Dry Steak

A Pale Surface With a Cooked Center

Stop cooking for the center’s temperature, not for the darkest possible crust.

A damp exterior, crowded basket, or insufficient preheating can explain weak browning. Correct those conditions on the next batch rather than sacrificing the current steak for color.

A Dry or Firm Center

Dryness usually means the center went farther than intended, though higher doneness naturally makes this lean cut firmer.

Common causes include trusting the timer without measuring, checking too late, or taking a temperature reading too close to the surface. Also make sure your thermometer is actually showing degrees Fahrenheit if you are using Fahrenheit targets.

For the steak already on your plate, a sauce or garlic-herb butter can improve the eating experience, but neither reverses overcooking.

Juices on the Plate After Resting

Some juice on the resting plate is normal and does not automatically mean the steak was cooked badly. Resting reduces the rush of juices when you cut the meat, but it does not eliminate all moisture loss.

Do not keep extending the rest in an attempt to stop every drop. Spoon the collected juices over the steak if you like.

For your next batch, note the steak’s thickness, the air-fryer setting, and the actual time it took to reach your endpoint. Those details give you a more useful starting point for the next batch.

Frequently Asked Questions

Is Steak Better in a Frying Pan or an Air Fryer?

A frying pan generally wins for a deep, dark sear; an air fryer wins for convenience and less hands-on cooking. Either can produce tender eye fillet when you control the center temperature. An air fryer is also a useful option when a grill is unavailable.

Can I Cook Eye Fillet Steak and Fries Together?

You can, but separate batches or independently controlled baskets usually give better results. Fries and thick fillets may need different cooking times, and crowding them together can compromise browning. Avoid leaving a finished steak cooking while you wait for the fries to become crisp.

Does Eye Fillet Need a Marinade?

No, eye fillet is naturally tender, so a marinade is optional for flavor rather than necessary for tenderness. Sugary marinades can darken quickly in an air fryer, making surface color an even less useful indicator of doneness. For a first batch, keep the seasoning simple and add your preferred sauce after cooking.

Can I cook a frozen sirloin steak in the air fryer?

No—not according to the cited air-fryer sirloin guidance. Thaw frozen steak in the refrigerator first. This method’s cooking times are for fully thawed eye fillet, not frozen sirloin.
