If you have been using your air fryer and not getting the desired result, chances are you did not preheat it. Preheating your air fryer is actually pretty simple to do.

01. Check Your Recipe:

You don’t have to preheat your air fryer for all types of food. Certain recipes ask for preheating and some do not. So it is ideal to check the recipe beforehand.

02. Set the Temperature:

If the recipe actually calls for a preheated air fryer, then note down which temperature they have mentioned. Set the temperature to that and turn on the air fryer.

03. Wait:

There isn’t much to do after that. All you do is wait for 5 minutes until it’s ready. If your air fryer is small, it will take 4-5 minutes to properly heat up. For larger ones, 7 minutes is more than enough.

Alternative Methods for Preheating an Air Fryer

Use the preheat function (if available)

Many air fryers come equipped with a preheat function that sets the appliance to the desired temperature and time, ensuring that it’s ready for use when you need it. This can be a convenient and efficient way to preheat your air fryer.

Some air fryers are compatible with stovetop use. You can preheat your air fryer by placing it on a stovetop burner set to medium heat for 5-7 minutes. Make sure to use oven mitts or a towel to handle the air fryer as it will become hot.

Common Mistakes with Air Fryers

Being a relatively needed addition to our kitchen, we all have some misconceptions surrounding air fryers. This leads to many user errors and unsatisfactory recipes. 

If you are trying to get a certain result in your air fryer but failing, again and again, you might need to check our list of the common mistakes with air fryers. We all have made these mistakes at least once in our life!

01. Do Not Overcrowd:

As most of us are used to cooking in larger batches, this might seem a bit tedious at first. But you will get used to it.

Cook your food in smaller batches instead of large ones. This allows the hot air to move freely and cooks the food from all sides. So not overcrowding the air fryer is a key thing. 

This especially is crucial if you are making crispy items like fries and chips. Space ‘em up and let ‘em breathe! 

02. About Meat Items:

If you are trying to make meat items like chicken fry or baked chicken but they always end up soggy, chances are, you are not drying the meat properly.

You should always bloat away any excess moisture from your food. This includes both meat and vegetables. If the surface is dry, it will cook faster and have a crispy, brown exterior. 

You can use paper towels to pat your food dry. Wet food also delays the cooking time. So keep that in mind. 

03. Regular Cleaning is a Must!

This mistake actually applies to all of us. We all are guilty of not cleaning our kitchen appliances as much as we should.

As the air fryer is relatively small, it can catch a lot of oil and grimes after a few uses. So it is a very good idea to give a gentle clean-up after each use. 

This also helps to not form any bacteria or mold inside, especially if you tend to not use it very often. The leftovers can form bacteria which can be detrimental to health.

04. It’s Not Just for Fried Food:

Who says air fryers are only for fried items? As is supposed to be a portable version of an oven, you should try all the recipes you try on a conventional oven. 

This is great if you live in a  small apartment with no oven. The small size of the air fryer is perfect for easy dinner ideas. You each easily make chicken roasts or other meat-based dishes on it.

You can reheat food items like chicken tenders, grilled ribs, bbq wings very easily on an air fryer too. 

05. Rotate and Cook:

This is a fairly obvious one. When we cook on a pan, we constantly move our food around to let it get even heat from all sides. So why don’t we do that for air fryers?

As the basket inside the fryer can not move in a circular motion like a microwave, you need to do it manually. Just open the air fryer at a regular interval and use a tong to gently rotate or flip your food. 

06. It Can Bake Too!

If you have never made chocolate chip cookies on an air fryer, you are seriously missing out! Air fryers can be used to make a wide range of desserts, cakes, doughnuts, and even casseroles. 

Of course, you’d have to preheat the air fryer for 10 minutes before baking. Cleaning is also necessary especially if you use your air fryer for savory food a lot. This will help to not leave a weird smell on your desserts. 

Tips for Using Your Air Fryer

  • Keep your air fryer on a dry, open countertop to not overheat it. 
  • Even though you don’t need to use any oil, sparing some oil can really help to fasten the process. Either way, tis’ better than deep frying food for sure! You can use vegetable oil substitutes too. 
  • It is a good idea to shake the frying basket from time to time especially if you are making fries. Shaking is easier than flipping or tossing. 
  • If you are cooking vegetables, do not chop them into very small pieces. Sammler items can get swept inside the fan of your air fryer. This is very risky. So be careful.
  • Cooking at a low temperature for a longer time results in crispier and better food than cooking at a high temperature for a shorter time. 
  • Use an air fryer to heat up your leftover food like chicken wings. They turn out to be absolutely scrumptious!
  • Make sure to purchase the right size for your family. Standard air fryers are made for single-person cooking. 

How to Clean an Air Fryer

  1. Unplug the air fryer and allow it to cool completely before cleaning.
  2. Remove the basket and any other removable parts.
  3. Wash the basket and other removable parts in warm, soapy water. Use a non-abrasive sponge or cloth to avoid scratching the non-stick coating.
  4. Rinse the parts thoroughly and allow them to air dry.
  5. Wipe down the interior and exterior of the air fryer with a damp cloth or sponge. Do not immerse the appliance in water.
  6. Use a soft-bristled brush or toothbrush to clean any hard-to-reach areas or crevices.
  7. Dry the appliance thoroughly with a clean towel.

How Often to Clean an Air Fryer

How often you should clean your air fryer will depend on how frequently you use it. As a general rule, you should clean your air fryer after every use to prevent the buildup of food particles and oils. This will also help to prevent odors and ensure that your air fryer continues to function optimally.

Additionally, you should deep clean your air fryer at least once a month to remove any stubborn food particles or grease buildup. To deep clean your air fryer, mix equal parts water and vinegar and wipe down the interior with the solution. Allow the solution to sit for 30 minutes before wiping it clean with a damp cloth or sponge.
