Air Fryer Steak — Comprehensive Guide to Thickness, Cuts, and Grading

Eighty percent of the reason an air fryer steak turns out poorly isn't the cooking method, but the meat selection. If you put thinly sliced bulgogi meat into an air fryer, no matter what temperature or time you use, the result will inevitably be dry and tough. Conversely, selecting the right meat can yield restaurant-quality steak using just an air fryer.

This article summarizes all the criteria for selecting meat for an air fryer steak. From thickness, cuts, marbling grades, frozen vs. refrigerated meat, vacuum sealing timing, to the most crucial step—room-temperature tempering—we cover the entire pre-cooking preparation process without omitting a detail.

Thickness — A Minimum of 2.5~3cm is Mandatory

The single most important criterion for an air fryer steak is thickness. It should be at least 2.5cm, ideally 3cm or more.

The reason lies in the nature of the air fryer's hot air. Because the hot air acts intensely on the surface of the ingredients, if the meat is thin, the internal moisture escapes before the surface even cooks. A piece of meat that is 1~~1.5cm thick will be completely well-done throughout in just 3~~5 minutes in an air fryer. If your goal is medium-rare or medium, sufficient thickness is necessary to allow cooking that utilizes the temperature difference between the inside and outside.

With meat thicker than 3cm:

Surface: Fast Maillard reaction from 200°C hot air → Flavor and Color
Inside: Residual heat slowly permeates, reaching the target temperature (57°C for medium-rare)

This time differential is required to achieve the desired doneness.

How to check at the grocery store: Directly observe the thickness at the meat counter or estimate based on the weight indicated on the package. For the same cut, a 200~~250g piece is much more likely to be thick enough compared to a 100~~150g piece.

Cuts — 3 Best Cuts for the Air Fryer

Not all cuts are suitable for the air fryer. The following three cuts are the best match for air frying.

1. Striploin (New York Strip)

This is the most highly recommended cut for air fryer steaks. Located just behind the ribeye, it is a less exercised muscle, making it tender with a good amount of marbling for great flavor. Offering excellent quality for the price, it is the most practical choice for home cooking.

Characteristics: Its vertical muscle fibers provide a satisfying chew. If there is a fat cap on the exterior, it slowly melts during cooking, adding rich flavor to the meat.

2. Ribeye

This cut features the most abundant marbling (intramuscular fat). It is characterized by a savory, buttery taste as the fat melts under heat. In an air fryer, the melting fat acts as a natural coating, maintaining a moist texture. However, the price is generally higher than Striploin.

Caution: If the marbling is excessive, a lot of fat can pool in the air fryer basket, potentially causing smoke. Adding a small amount of water to the bottom of the basket can help reduce smoking.

3. Tenderloin (Filet Mignon)

The most tender cut available, it contains almost no fat. Prices are highest due to the small yield per cow. Because it lacks fat, it will dry out quickly if overcooked, so managing it to a medium-rare or medium level is crucial. This is a cut where air fryer temperature control is of paramount importance.

Cuts to Avoid

Shank: Contains a lot of connective tissue, suitable for long, low-temperature cooking. It becomes tough when cooked quickly in an air fryer.
Sliced Meat (e.g., for Bulgogi): Overcooks in seconds in an air fryer due to being far too thin.

Marbling Grade

South Korean beef grading follows the order of 1++, 1+, 1, 2, 3. The most suitable grades for air fryer steaks are 1+ or 1.

1++ (Top Grade): Marbling is so abundant that excessive fat may run out in the air fryer, causing smoke. It is better suited for pan-searing or grilling.
1+ to 1: Features a good balance of marbling and is ideal for air fryer cooking.
2 to 3: Less marbling means less inherent flavor, but this can be compensated for via olive oil coating and butter finishing.

Imported beef (like USDA Choice) offers marbling similar to the Korean Grade 1, making it a cost-effective and highly suitable option for air fryer cooking.

Frozen vs. Refrigerated Meat

Advantages of Refrigerated Meat

Juices and texture are much more vibrant.
Dry-aged products provide a uniquely deep flavor.
Cooking can begin immediately without needing a separate thawing process.

The Reality of Frozen Meat

A significant amount of 'steak meat' sold in supermarkets is actually meat that was imported frozen, thawed, and then displayed in the refrigerated section.
Properly flash-frozen (-40°C) meat suffers minimal cellular damage, meaning its texture difference from refrigerated meat is negligible after thawing.
Vacuum-packed, flash-frozen products are widely sold online and offer very stable quality.

Conclusion: Choose refrigerated when possible, but frozen meat—if thawed correctly—is perfectly suitable for air fryer steaks.

Room-Temperature Tempering — 30 Minutes to 1 Hour

This is the most frequently ignored step in steak preparation. If you put cold meat straight from the fridge into an air fryer, the temperature difference between the outside and inside is too vast; the surface will cook while the center remains cold.

Solution: Take the meat out of the refrigerator 30 minutes to 1 hour before cooking and let it sit at room temperature. Once the internal temperature of the meat approaches room temperature, heat transfers evenly, allowing you to achieve the desired doneness much more accurately.

Caution: Leaving it out for too long risks bacterial growth. Do not exceed 1 hour.

Moisture Removal — Patting Dry with Paper Towels

The step of pressing the meat's surface with paper towels to remove moisture prior to cooking must not be skipped.

If there is moisture on the surface, the air fryer's hot wind spends its initial energy evaporating that water. The Maillard reaction only begins after all surface moisture is gone, which ultimately results in less browning and weaker flavor. Removing the moisture beforehand ensures the heat is immediately used for the Maillard reaction, quickly creating a delicious, crusty exterior.

Timing for Opening Vacuum Packaging

When you open vacuum-sealed steak, it might initially emit a slightly sour or stale odor. This is a natural phenomenon that occurs in a vacuum state and will dissipate after 30 minutes to 1 hour of exposure to the air. This process is called Blooming.

Instead of cooking it immediately upon opening, let it rest open in the refrigerator for 30+ minutes, or combine this with the room-temperature tempering step to naturally allow the odor to escape.

Notes

The thicker the meat, the longer the cooking time, making it most accurate to use a meat thermometer to check the internal temperature.
Because heating power varies by air fryer model, don't set a prolonged cooking time on your first try; instead, check the progress midway.
Ribeye, with its high marbling, releases a lot of fat. Adding 1~2 tablespoons of water to the bottom of the basket can mitigate smoke.

FAQ

Q1. Can I cook 1cm thick steaks from the supermarket in an air fryer? A. It is possible, but it will likely end up cooked beyond medium and become dry. For thin meat, quickly searing it over high heat in a pan is much better than air frying.

Q2. Which is better for an air fryer, imported Striploin or domestic Striploin? A. The suitability for air frying is similar for both. USDA Choice Striploin offers great value due to uniform marbling and lower cost. Domestic beef provides clear grading, making selection straightforward.

Q3. Can I defrost frozen meat using a microwave? A. Avoid this if possible. Microwave defrosting causes parts of the meat to start cooking, leading to a highly uneven overall texture. Thawing in the refrigerator (a day prior) or in cold water (30~60 minutes) is strongly recommended.

Q4. Between Tenderloin and Striploin, which is easier for an air fryer beginner? A. Striploin is easier. Tenderloin lacks fat and quickly becomes dry if overcooked, while Striploin has enough marbling to be more forgiving of slight cooking mistakes.

Q5. When should I salt the steak? A. There are two good methods. Salting 1 hour or more before cooking allows moisture to be drawn out via osmosis, dissolve the salt, and be reabsorbed, deeply seasoning the meat. Salting right before cooking minimizes surface moisture. Salting 5~10 minutes before cooking is the worst choice (moisture has been drawn out but not yet reabsorbed).

Conclusion

The success of an air fryer steak is determined by meat selection rather than cooking technique. A minimum thickness of 2.5~3cm, a choice of Striploin or Ribeye, a marbling grade of 1+ or higher, 30 minutes of room-temperature tempering, and moisture removal before cooking—if you adhere to these five criteria, you can easily produce an outstanding steak even in an air fryer. Good ingredients are more than half of a good dish.
