Factors to Consider

High Smoke Point

A higher smoke point is important when frying french fries. Using lower smoking point cooking oils might get your food easily burned at a high temperature and release free radicals that could affect the flavor.

Because the hot oil has broken down, the frying time of your frozen potato fries will be ruined, resulting in soggy and bitter fries.

Neutral Flavored Oil

Neutral flavored or tasteless oil is a must when making french fries. Choose flavorless cooking oils if you don’t want to add taste to your fries and want typical potato fries.

Cooking oils like peanut and sunflower oil might add a nutty flavor to your fries.

Frozen potato fries absorb oil to cook through, and using flavored oil might affect the natural taste and texture of your fries.


Using expensive cooking oils to fill your deep fryer sounds impractical, especially if you’re frying French fries at home to satisfy your cravings.

There are economical but healthier cooking oil options that could help satisfy your crispy fries cravings and your budget.

What is The Healthiest Oil To Fry French Fries?

The healthiest oil to fry French fries is Tallow oil or lard. This is because it contains high saturated fat and monosaturated fat. 

Oils with high free fatty acid content are resistant to extreme heat and are made of natural fat. [2] 

VCO is also a good choice because its high saturated fat content makes it stable and doesn’t change easily during frying, even at 365° F.

Should You Thaw Frozen Fries Before Deep-Frying?

No, you shouldn’t thaw frozen potato fries before frying because they might get soggy and lose their crispiness after cooking. 

Thawed French fries in the fryer is a common mistake for some people. 

If you thaw frozen fries, the ice covering them melts and gets absorbed by the fries, resulting in a soggy texture.

Deep frying frozen potato fries or fried foods is a technique to get the super crispy fries that most of us crave.


Can you use olive oil for frying frozen french fries?

No, you can’t use olive oil for frying frozen French fries because of its low smoke point of 374° F.

Extra virgin olive oil might start to burn before the frozen potato fries reach the full frying process, resulting in soggy fries.

But if air frying at an air fryer, you can spray light olive oil on the cooking basket of the air fryer before putting your frozen potato fries.
