Here’s a Step-by-Step Guide on How to preheat an Air Fryer?

Check to see if the air fryer is clean

Although not every manufacturer advises you to clean your air fryer, now that you’re an adult, you’ll have to take responsibility.

Despite the fact that air fryers are less filthy, you should clean them before each usage. The leftovers and foul odor from the previous dinner may damage the next meal you want to cook.

If you clean your air fryer on a regular basis, it will last a long time. You will save some money by not having to maintain and repair the equipment.

However, avoid using abrasive cleaning products because they may cause damage. Because the air fryer doesn’t use much oil, and it makes cleanup easier, you’ll want to use it sparingly.

Turn on the air fryer after plugging it in

The following step is the most evident. The air fryer must be plugged in and turned on by pressing the button. Make sure you follow these instructions to the letter.

First, double-check the air fryer’s voltage requirements and the power supply you have at home. You wouldn’t want to use a 220 V outlet to power your 120 V grill.

Turn the machine on by pressing the power button once you’ve double-checked the power source. You should have no issue positioning the button if you followed the first step correctly.

Set a timer

After you’ve turned on your air fryer, you’ll need to set the timer. As previously stated, the optimal time varies from one unit to the next. As a result, consulting the user handbook is your best bet.

The ideal time is usually between 3 and 5 minutes. Because most devices have a pre-set pre-heating period, you should refer to the manufacturer’s instructions for the length. You cannot go wrong with the meal if you follow that advice.

Pre-heat the oven to the desired temperature

The temperature of each air fryer device varies, just like the time. The temperature to preheat the equipment is usually set by the manufacturer.

If your air fryer does not have any, you can increase the temperature to 400 degrees Fahrenheit to make the food crispier.

Pro tip: If the recipe or air fryer does not require preheating, you can add a few minutes to the cooking time to achieve the desired crunchy texture, but this will increase the cooking time. But the wait will be well worth it.

How Long Does It Take for an Air Fryer to Preheat?

There is no single number that indicates how long your air fryer will need to warm. It usually takes two minutes, but the best strategy is to leave it on for five minutes.

As a result, both the surface and the air within the oven will become heated, and you will be ready to cook the dish. Preheating instructions may be specified by some manufacturers, so double-check.

It goes without saying that the temperature is critical. The recommended temperature range for a properly crammed basket, which covers 3/4th, is between 350 F and 400 F.

If you cook your meal below 350 degrees Fahrenheit, it will be undercooked, and cooking it above 400 degrees Fahrenheit would cause it to burn. The meal is tasty, crisp, and cooked to perfection within this range.

When Should you Preheat your Air Fryer (And When Should uou Not)?

Preheating at the wrong time

Foods that are thick and raw

Preheating is not required for cooking particularly thick or thick/frozen meats such as roasts, large chicken breasts, or anything raw that needs to be cooked through the center.

If you don’t preheat, the outside will cook way too quickly and crisp before the inside is fully cooked. This is especially problematic when cooking raw, thick, or frozen raw foods.

The center of the meat, roast, or frozen center will still be raw. Consider that for a moment.

Raw food will not fully cook if the temperature is too high and the cooking time is too short. The only exception is when you want your steaks rare or medium-rare.

Foods that don’t need to be crisped

Foods will cook hotter and crispier on the outside if they are preheated. When cooking delicate or small cut veggies, the outside of the vegetables may burn before the inside is tender.

In many circumstances, pre-heating the dish too hot causes the food to dry out. So, if you want to pre-heat, just cut the cooking time in half.

Pastries, breads, cakes, and other similar items

When air frying fast bread or little cakes, start with a cold air fryer so the bread/pastry may progressively heat or cook.

The outside will be overly crispy from preheating, and the inside will be doughy and uncooked. The crust will be hard, but the dough within will be raw.

When you produce smaller bite-sized pastries or cakes in the air fryer, the center will cook faster and the outside will not burn.

Don’t use parchment paper to preheat your air fryer!

During pre-heating, the paper will blow around and may collide with the heating element, causing it to burn.

If you’re preheating and using parchment, wait until the parchment has been preheated before inserting it.

When is the Best Time to Pre-Heat?

Reheating leftovers, smaller items, and frozen foods that are thinner

This can quickly crisp up food.

Good Crust and Sear

Good Crust and Sear: Preheating can help thin meats like chicken tenders, thin pork chops, and steaks.

When you want a good sear or crispy exterior on steaks that aren’t fully cooked in the middle, use this method. 


To produce a beautiful crust and sear, you’ll need a preheated air fryer. This will also cook the steak quickly on the outside, resulting in a good medium-rare or rare texture.

Pork chops can also be cooked in a preheated air fryer to achieve a crust and keep the meat from becoming too dry in the middle.

Precooked frozen foods

Frozen French fries, cheese sticks, and fish sticks are examples of precooked frozen foods. Get a crispy outside when the meal is already cooked and you want to cook it hot.

Mistakes you’re Making With your Air Fryer

You Don’t Cook Veggies

You don’t have to limit yourself to making fried chicken in there; you can also make wonderful and nutritious fried vegetable meals.

Air fryers are similar to countertop convection ovens, but with a turbo setting. The machine cooks meals quickly by using the power of hot circulating air.

You can create everything in the air fryer in minutes, from stuffed peppers to asparagus to sweet potato hash.

You Crammed too much into the Basket

Give your food some breathing room! Making a large amount at once may seem like a good way to save time and energy, but you risk ruining your meal.

Resist the urge to stuff a lot of food into the air fryer basket; this will result in an unevenly cooked mess.

You Don’t Bake

You don’t bake using an air fryer for healthful baked products like breakfast casseroles, doughnuts, and desserts.

The pans are perfectly sized to fit within the fryer basket. They’re completely necessary for baking in an air fryer, so just toss them in.

You’re Either using too much or not Enough Oil

While some recipes don’t use any oil, the majority do and it’s still a lot less than the oils used in traditional fried foods.

Most recipes only require 1-2 teaspoons or 1-2 tablespoons for breaded things. You should mix breadcrumbs with 1-2 Tbsp of oil for breaded meals (chicken fingers, fish sticks) and it works excellent.

For other recipes, just brush lightly with oil most recipes only require 1-2 tsp per serving (or less). It depends on the recipes some recipes require no oil at all, while others only require a light coating of oil spray.

“After each usage, they only need to be washed with hot soapy water every now and again, with the occasional soak and mild scrub.

You probably won’t be able to put it in the dishwasher, so double-check and don’t make that mistake. There are a few shortcuts you may use to make cleaning up a breeze.
