Some foods need to be kept in the refrigerator to slow the growth of germs, keeping them fresh and safe for longer. They are foods that have a “use by” date and “keep cold” on the label, such as milk, meat, and ready-to-eat foods. Food needs to be cooled down before being refrigerated (usually within 2 hours), stored in the refrigerator, and eaten within 2 days.

Avoid keeping food in open tin cans in the refrigerator, as the food inside can develop a metallic taste. Follow the manufacturer’s instructions or place food in sealed containers or bowls before refrigerating.

Step 1. Prepare the necessary items for heating

You should choose items made from metal (aluminum, stainless steel, …) or glass, or porcelain to put in the air fryer.

Do not use “low heat” items such as plastic trays, nylon, or mica. If it’s fried or grilled dishes, you can use parchment paper, or foil or place it directly on the baking tray.

Step 2. Start the air fryer about 5 minutes in advance

Just like when frying, this helps the temperature in the inner pot to stabilize, reaching the required level. You just need to plug in the power and adjust it to 100 – 150 degrees Celsius.

Step 3. Put the food container in the pot

The food is put into the utensils, then immediately put into the frying basket of the pot. You should act quickly, to avoid heat escaping. Then set the time for about 5-10 minutes. (At this point, the pot already has the temperature set in the previous step! At 100 – 150 degrees Celsius).

Step 4. 5-7 minutes, check the food once

By taking the tray out normally, if it has not reached the desired temperature, then add it again.

  • Depending on the type of food you put in, soup, fried dishes, braised dishes, etc., there will be different times. If you reheat fried food, baking will be about 4-5 minutes faster. As for everyday dishes such as soup, fried, stir-fried, it takes 5-10 minutes.
  • Moreover, if the amount of food to be reheated is too much, you can also set a longer time for the temperature to heat evenly.
  • You can take out the tray very easily even while it is reheating. The pot will automatically turn off the power, when the tray is inserted, it will continue to work.

#1. Forgot to preheat

Forgetting to preheat the pot can result in the food not being cooked enough.

For the best quality, set the air fryer to the right temperature for a few minutes before adding the food. This method helps the food to cook evenly, and at the same time saves cooking time.

#2. Not cleaning properly

Between each cooking time, you should disassemble the parts of the pot and wash it thoroughly. Most parts can be safe in the dishwasher, making housewives easier to clean.

You need to clean the main body of the pot from time to time to remove grease and food debris. If you don’t clean the pot between each cooking session, the flavors of the previous dish may stain your food.

#3. Choose a fryer that is not suitable for your kitchen and lifestyle (This is just an extra point)

Air fryers come in many different shapes, sizes, and colors for you to choose from. When you get one that suits your needs, you’ll use it more often, making the most of the pot’s performance.

If you are living alone, choose a small pot that cooks enough for 1 or 2 people to eat. If you are living with your family, then you need a larger capacity pot to cook more food.

The style and color of the pot in harmony, bringing accents to the kitchen is also a way for you to embellish the space, making cooking more interesting.

#4. Spray the oil directly on the food in the pot

In the process of cooking food with a fryer, the addition of cooking oil is a common occurrence.

But you should not put food in the pot and spray cooking oil directly on it. Because doing so can create a build-up of sticky substances on the inside of the pot.

Take the food out and then add the cooking oil, you can spread the oil more evenly, and the excess oil will not flow into the pot, making it difficult to clean.

#5. Put the working pot in the drawer

The air fryer will release some smoke and steam. So when you are using them, do not leave them in closed cabinets or shelves.
