How Do You Crisp French Fries In An Air Fryer?

It is easy to make sure that your french fries turn out to be crispy when you cook them in the air fryer. Soaking the french fries in water for 10 minutes will help to remove the starch off the potatoes. This added step can make a huge difference to your french fries turning lovely and crunchy.

Why are my fries not crispy in the air fryer? You fries may not be very crispy due to two reasons.

  • The air might not have been hot enough when they were air fried.
  • The air fryer basket was too full and therefore the fries have not cooked evenly.

It is best to cook your french fries at a high temperature and in small batches to allow them to all get cooked and crispy.

Why Do You Have To Soak Potatoes Before Air Frying?

Soaking potatoes before air frying them helps remove the starch that is on the outsides of the potato. Potatoes naturally contain a lot of starch and soaking in water is the best method to reduce this.

If you do reduce the starch on your potatoes, your french fries will be able to crispy up nicely when you cook them in the air fryer.

How Much Oil Do You Put In An Air Fryer For French Fries?

Do you put oil on fries in the air fryer? Yes, you can do it but it really is not that necessary. If you do not want to put any oil on your french fries when you are cooking them in your air fryer, the french fries will still cook well.

You will not need to use much oil at all, should you decide to use some. We would recommend using a small amount of oil per batch of french fries you would like to cook. The less oil you use when cooking your fries in the air fryer, the lower in fat and calories the fries will become. This will make the fries much healthier overall which is one of the best things about cooking with an air fryer.

How Long Should You Air Fry French Fries?

The most common amount of time that is used to make sure that your french fries will cook perfectly is between 12-15 minutes. Allow your fries to cook for no longer than 15 minutes as 380 degrees Fahrenheit. This will allow them to reach a desirable crunchiness.

Used to cooking at Celsius? Preheat your air fryer to 193 degrees Celsius.

Again, t is best to not overfill the basket when cooking your french fries in an air fryer. After all, we want to make sure that all the fries are cooked evenly.

French Fries In Air Fryer Temperature

If you are wanting to air fry your french fries that have been previously frozen, then preheating your air fryer to 400 degrees Fahrenheit will be a great temperature. 400 degrees Fahrenheit is equal to 204 degrees Celsius. Heating your air fryer to this temperature will allow the french fries to cook thoroughly while becoming crispy on the outside.

Place the frozen fries in the air fryer basket and shake the basket. Doing this will allow the fries to evenly distribute. Cook your frozen french fries for 10 minutes at 400 degrees Fahrenheit. This’ll allow them to perfectly cook in your air fryer.

If you are air frying french fries that are not frozen, using a cooler temperature will work better. A temperature (like 325 degrees Fahrenheit) will be strong enough. 325 degrees Fahrenheit equals 162 degrees Celsius.

FAQs On Oils For Air Frying French Fries

What Oils Should Not Be Used In Air Fryer?

The only oil we would recommend that you do not use in an air fryer is coconut oil. Coconut oil can easily burn when it is raised to high temperatures. Coconut starts to burn when it reaches 350 degrees Fahrenheit which equals to 176 degrees Celsius. Air fryers tend to cook at higher temperatures at this, especially when cooking french fries.

What Is The Best Oil To Air Fry With?

If you are wanting to add a lovely crunch to your french fries but no added extra taste, we would recommend using olive oil. If you are wanting to add a little flavor to your fries, then we would recommend adding a nutty sesame oil. 

Do You Spray Oil On Frozen French Fries In Air Fryer

When cooking frozen french fries there is not any need to add a large amount of extra oil. Frozen fries are already prepared and cooked in oil before being packaged. Therefore, you will not need to spray extra oil to make sure that the frozen fries do not stick to the air fryer basket. If you would like to add extra flavor to your frozen french fries then you can spray some oil on them, such as sesame, that will add a nutty flavor. Adding oil is a personal choice rather than a need when preparing your frozen fries to be cooked in your air fryer.

Choose An Oil With A High Smoke Point

If you are cooking your french fries in an air fryer then you will want to make sure that you choose an oil with a high smoke point. A high smoke point means that the oil will not burn if it reaches a high temperature.

When cooking your french fries in the air fryer you will need to use a very high temperature. Choosing which is the best oil to use is a personal taste preference. But making sure the oil has a high smoke point is key to crispy, unburnt fries!
