All you need to do is toss your delicious food or meat into the air fryer baskets, turn your machine on, set your timer, and come back once your timer is complete to a fully cooked meal.

Air fryers are similar to ovens because it roasts and bakes. The heating mechanism is located at the top along with a powerful fan. When in use, it makes food super crispy and crunchy in no time -because it heats up fast and cook food quickly.

How To Use the Air Fryer?

The air fryer cooking process is like a convection oven. The heating mechanism in the upper section generates hot air, which is then circulated swiftly all over the meal drawer by the fan.

With the meal raised inside the grate or basket, the hot circulated air will touch all meal sides; with very little or no oil, your meat or food will turn brown and crispy. The step-by-step process is as follows:

Place Your Meal in the Basket

Depending on the size of your air fryer, the basket could be between 1 – 10 quarts. You may need to add 1 or 2 teaspoons of vegetable oil in some cases.  

Set the Temperature and Timer

Air fryer cooking temperature and timer are ranged between 5 – 25 minutes at 350 to 400 degrees Fahrenheit, depending on the meal you’re cooking.

Allow the Meal to Cook

In some cases, you may need to turn the food halfway between cooking time to help crisp up evenly. 

Do You Need Oil to Cook in an Air Fryer?

Not necessarily. Let me explain; no oil is needed when cooking your food in an air fryer. Most people take advantage of not using oil with an air fryer, but you can if you prefer using oil.

However, you must add your required quantity of oil to your ingredients before loading them in your air fryer, not inside the fryer’s basket or rack. 

Based on individual preference, adding a slight vegetable oil into food such as meats, potatoes, or baked meals before air frying them will add a crunchy and crispy layer to your cooking once you are done. However, you can opt not to use oil and still get a crisp and crunchy outcome after cooking your food.

To preheat your air fryer: most air fryers have a preheat setting, and few don’t. Some food recipes require preheating your air fryer before cooking. 

Here’s how to preheat your air fryer:

  • Make sure removable parts, such as baskets and racks are dry, clean, and correctly inserted into their units.
  • Once you are done, select the preheat setting programmed on your air fryer or follow the user manual’s instructions.
  • Allow your appliance to preheat.

We recommend a three minutes window for most air fryer models. But for bigger oven-style air fryers, five minutes would be fine.

How To Clean the Air Fryer?

  • Step 1: Unplug your air fryer and allow it to cool down for a minimum of 15 minutes to prevent shock or accidental burns.
  • Step 2: Remove parts and wash with warm soapy water. If the removable parts have charred or greased food on them, soak in hot water for 10 – 15 minutes before scrubbing them with a non-abrasive brush or sponge.
  • Step 3: Clean the heating element at the upper section of your air fryer with a dried cloth.
  • Step 4: Clean the interior of the air fryer with a non-abrasive sponge or a damp microfiber material with a dishwashing soap splashed on it. Once you are done, use a clean cloth to wipe off any soap residue on the air fryer.
  • Step 5 –check every nook and cranny of your fryer is ensure it is scorched. Voila! Reassemble your removable air fryer parts into their unit.

Is Air Fryer Foods Healthy? – Cancer

Air fryers are innovative kitchen appliances designed to substitute conventional deep frying. It has a few ways it could affect nutritional content in meals and impact cancer risk because the air fryer uses little to no oil, which takes away the need to reheat oil. These affect the number of acrylamide chemicals known as 2A carcinogens produced in the body. 

Despite this health advantage, it is essential to note that type of meal you eat in various forms is more vital than a single mood of preparing them. Some people prefer cooked meals prepared in an air fryer, which does not mean it is healthier than other food.

As a cancer patient, ensure to include various cooking methods into your regular dietary routine for optimal health benefits.
