Smoking In The Air Fryer: What You Need To Know

Air fryers are a popular kitchen appliance for cooking food in a healthier manner. However, one common issue with air fryers is that they can sometimes emit smoke. This smoke may be caused by a variety of factors, such as fatty foods, food debris buildup, the use of incorrect oils, overcrowding the basket, and cooking for too long. To prevent an air fryer from smoking, it is recommended to use a splatter guard or foil liner to catch excess grease, absorb grease with bread or paper towels, dilute oils with water, clean the air fryer regularly, and choose oils with a high smoke point. Additionally, it is important to avoid overcrowding the basket and adjust cooking temperatures and times accordingly.

Fatty foods and grease splatter

Fatty foods like bacon tend to produce too much grease in an air fryer. The interaction of high fat and rapid heat may create splatters or deposits of grease at the bottom, which is dangerous to overheating and can cause unpleasant odours. Poorly draining grease can also cause flare-ups or damage to the appliance.

To avoid this, it is recommended to use a drip tray to catch excess fat or to cook fatty foods in smaller batches to minimise smoke and mess. You can also try cooking high-fat foods in a regular cooktop or oven, as air fryers are not ideal for all foods.

To prevent grease splatter, you can line your air fryer with parchment paper, which will catch the residue and prevent it from burning up as smoke. For oven-style air fryers, place the paper on a baking sheet, and then place it on a rack below the food tray. For basket-style air fryers, line the parchment paper at the bottom of the basket and curl the edges of the paper upwards to create a wall, preventing grease from dripping below.

If parchment paper is not available, you can also use a slice of bread to absorb the excess grease. Place the slice at the bottom of the basket to catch the drippings, and prevent them from sputtering all over the air fryer basket and causing white smoke.

Another simple trick is to add a couple of tablespoons of water to the bottom of the basket. This will stop grease from burning and smoking up your kitchen, without steaming the food. Just make sure that the water isn't coming into direct contact with any electrical components.

Food debris and residue

To prevent food debris and residue buildup, it is important to clean your air fryer regularly. The frequency of cleaning will depend on how often you use it, but a thorough cleaning is recommended at least once a week. After each use, it is a good idea to wash the removable parts, such as the basket, pan, or tray, with warm water and dish soap. Let these parts dry overnight before placing them back into the fryer. You can also use disposable air fryer aluminum foil or parchment paper liners to catch any residue and make cleaning easier.

For a deeper clean, you can fill the air fryer basket with a cup of water and turn it on at a high setting for a few minutes. This will help loosen any caked-on food or grease. You can then submerge the removable parts in hot, soapy water for around 30 minutes and scrub them gently with a soft-bristled toothbrush. To remove stubborn, stuck-on residue, you can make a paste with baking soda and water, apply it to the affected areas, and scrub it off with a soft-bristled toothbrush after a few minutes.

It is important to note that you should avoid using abrasive cleaners and scrubbers, as they can scratch the non-stick parts and exterior of the air fryer. Additionally, it is recommended to clean the coils and the area surrounding them inside the hull of the fryer regularly, as this area is prone to food splatter and gunk buildup, which can be a fire hazard if left unattended.

Using the wrong oil

When using an air fryer, it is important to use the correct type of oil. Oils with lower smoke points can break down under the intense heat of an air fryer, potentially releasing harmful chemicals that can taint your food with a nasty flavour or even char it.

Oils to avoid due to their low smoke points include walnut oil, pumpkin seed oil, flaxseed oil, unrefined olive oil, and coconut oil. These oils can burn and smoke more easily than oils with higher smoke points, such as avocado oil, canola, sunflower, or regular vegetable oil.

It is recommended to brush oil onto your food before placing it in the air fryer or use a cooking spray. However, be cautious as some oils contain additives like soy lecithin, which can stick to the inside of the air fryer, leading to a grimy build-up that is difficult to clean and could ultimately shorten the lifespan of your appliance.

Therefore, it is crucial to choose the right oil and use it sparingly to avoid potential issues.

Overcrowding the basket

To avoid overcrowding, it is recommended to cook in batches. This ensures better airflow in each batch and faster, better results. Cooking in single layers is a good rule of thumb, but there are exceptions. Certain vegetables, such as Brussels sprouts, broccoli, and similar items, can be stacked and loaded, depending on the recipe. For these types of food, it is still important to stir or shake them halfway through the cooking process to ensure even cooking.

The size of the air fryer basket also matters. If you find that you frequently need to cook larger quantities of food, consider investing in an air fryer with a larger basket. This way, you can cook everything at once without worrying about overcrowding.

Additionally, it is important to follow the manufacturer's recommendations for how much food to load into your specific air fryer model. By avoiding overcrowding, you'll ensure properly cooked and crisped food, making the most of your air fryer's capabilities.

Cooking for too long

If your air fryer is smoking, it could be because you are cooking your food for too long. Air fryers get very hot, very quickly, so your food may be burning and causing the air fryer to smoke.

If you are cooking food at a high temperature, it may be better to reduce the heat and cook the food for longer. This will prevent burning and reduce the risk of smoking.

It is also important to ensure that your air fryer basket is not overcrowded. If you put too much food in the basket, the air will not be able to circulate properly, and your food may burn and smoke.

Additionally, the type of food you are cooking can contribute to smoking. Fatty foods, such as bacon, chicken thighs, and sausages, tend to release more grease, which can splatter onto the heating element and cause smoking. If you are cooking high-fat foods, try reducing the temperature and increasing the cooking time.

To prevent smoking, you can also try lining your air fryer with parchment paper or placing a slice of bread at the bottom of the basket to absorb excess grease.

Finally, make sure to regularly clean your air fryer, as a buildup of grease and food particles can also cause smoking.
