Air Fryer And Sous Vide: The Perfect Sear?

Air fryers are a popular alternative to ovens and pans for cooking and searing food. They are more energy-efficient and take up less space. However, they may not be suitable for all types of food. For example, it is not recommended to use an air fryer for sous vide cooking as it cannot achieve the same even temperature as a water bath. Additionally, air fryers may not get hot enough to sear certain foods, such as steak, and can produce a lot of smoke. While some people have tried using an air fryer to sear food cooked in a sous vide, the general consensus is that it is not a good idea.

Air fryers don't get hot enough to sear without overcooking the food

Air fryers are not suitable for searing sous-vide food because they do not get hot enough to achieve a quick sear without overcooking the food. Air fryers are essentially just mini-convection ovens, and while they are great for browning, they are not designed to generate the high heat required for searing.

The purpose of searing is to create a browned, caramelised crust on the surface of the food, which requires a high temperature to produce. Air fryers, even at their highest settings, typically do not exceed 400-500 degrees Fahrenheit, which is not hot enough to achieve a proper sear.

Additionally, the cooking process in an air fryer is relatively slow, especially when compared to other searing methods such as pan-frying or grilling. By the time the surface of the food starts to brown, the rest of the food will likely be overcooked. This is especially true for foods with a high surface-to-mass ratio, such as a steak.

Furthermore, attempting to sear fatty foods in an air fryer can result in excessive smoking. The hot air inside the fryer causes the fat to smoke, and when the fryer is opened, the smoke escapes and can fill the room.

While air fryers are convenient and versatile, they are not the best option for searing sous-vide food. Other methods, such as pan-frying, grilling, or torch searing, are more effective and produce better results.

Air fryers are not suitable for sous vide as they can't hold a steady low temperature

Air fryers are not suitable for sous vide cooking as they are unable to maintain a steady low temperature. Sous vide cooking requires precise temperature control, with the food being cooked at a specific temperature for an extended period. While air fryers can be used for browning or searing after sous vide cooking, they are not designed for the precise temperature control needed for sous vide.

Air fryers are essentially mini-convection ovens, which use a fan to circulate hot air and cook food. They are not capable of achieving the same level of temperature stability as a dedicated sous vide machine. Ovens, including air fryers, tend to have less precise temperature control, with the heating element turning on and off to maintain the desired temperature. This means that the actual temperature inside the oven can fluctuate above and below the set temperature, which is not ideal for sous vide cooking.

Additionally, air fryers typically operate at higher temperatures than those required for sous vide. Most air fryers have a maximum temperature of around 400 degrees Fahrenheit, which is significantly higher than the temperatures typically used for sous vide, which can be as low as 130 degrees Fahrenheit. While some air fryers may have lower temperature settings, they are still not designed for the precise temperature control needed for sous vide.

Furthermore, sous vide cooking typically involves sealing the food in a plastic bag and submerging it in a water bath. This is not possible with an air fryer, as plastic bags should not be placed in an oven due to the risk of melting or catching fire. While some people have suggested using aluminium foil instead of plastic, this defeats the purpose of sous vide, which relies on the even temperature of the water to cook the food evenly.

In conclusion, while air fryers may be convenient for browning or searing food after sous vide cooking, they are not suitable for the actual sous vide process due to their inability to maintain a steady low temperature and the risk of melting plastic bags. For precise and even cooking, a dedicated sous vide machine or a high-precision oven is a more appropriate choice.

Air fryers can't be used with water, which is necessary for sous vide

Air fryers cannot be used with water, which is necessary for sous vide. Sous vide is a cooking method that involves sealing food in a plastic bag and then cooking it in a temperature-controlled water bath. The even temperature of the water circulates around the food, cooking it evenly and precisely. This cannot be achieved with an air fryer, as air and water conduct heat differently. Air is a poor conductor of heat, which is why air fryers use high temperatures and a fan to move the air. In contrast, water is an excellent conductor of heat, making it perfect for sous vide cooking.

While some people have tried to use an air fryer for sous vide by filling a plastic bag with water and placing it in the air fryer, this is not recommended. Plastic bags should not be put in an oven or air fryer as they can melt and possibly catch fire. Even if the plastic bag doesn't melt, you won't get the same results as sous vide because you won't have a perfectly even temperature.

Air fryers are essentially mini-convection ovens, great for browning and crisping food but not suitable for sous vide cooking. If you're looking for a way to cook food in an oven in a bag, there are roasting bags or parchment paper if the food is small enough. Alternatively, you can use aluminium foil to wrap your food tightly and prevent it from drying out.

If you want to achieve similar results to sous vide without using a sous vide machine, you can try braising in a slow cooker or Dutch oven in a low oven. Another option is to invest in a C-Vap oven, which is a high-precision, stable oven that uses injected steam to control temperature. These ovens can transition from a low-temperature cook to a hotter searing phase, offering dry cooking with sous vide levels of control.

Air fryers are just ovens, so the results will be similar

One user reported that they were able to get a decent sear in an air fryer by preheating a small cast-iron pan inside the fryer at its highest temperature setting and then placing the meat on it. However, another user reported that they tried this method and it was a failure.

If you are looking for alternative ways to sear sous vide, some suggestions include using a torch, an induction hob and skillet, or a pan fry.

Air fryers are not suitable for searing fatty meats as they will smoke

Additionally, air fryers don't get hot enough to achieve a quick sear without cooking the food further. This is especially true for fatty meats, which are likely to smoke up inside the air fryer. Even if you preheat the air fryer for a long time, it won't get hot enough to sear a steak properly.

If you're looking for a good sear on your steak, it's best to use a cast-iron pan or a torch. While these methods may create smoke, you can minimise it by using an oil with a high smoke point, like avocado oil or grapeseed oil, and by drying your meat thoroughly before searing.
