Is It Healthy to Cook French Fries in Canola Oil?

What is The Healthiest Oil To Fry French Fries?

The healthiest oil to fry french fries is avocado oil. Avocado oil is rich in monounsaturated fats and has a high smoke point, making it an ideal choice for deep-frying.

Additionally, avocado oil is low in saturated fat and contains beneficial antioxidants, which can help protect against oxidative damage.

Should You Thaw Frozen Fries Before Deep-Frying?

It is not necessary to thaw frozen fries before deep-frying. If you are using a deep-fryer, it is best to follow the manufacturer’s instructions for deep-frying frozen fries.

If you are using a pot on the stove, you may need to adjust the temperature of the oil or add additional time to the cooking process.

What Oil Does McDonald’s Use for French Fries?

McDonald’s uses a blend of vegetable oils, including canola [1], corn, and soybean oil, for their french fries.

The exact proportions of the blend vary depending on the location. Additionally, McDonald’s french fries are cooked in hydrogenated vegetable oils, which are high in trans fats and should be avoided if possible.


Canola oil is a popular choice for frying french fries due to its heart-healthy fats, light flavor, and high smoke point. Additionally, canola oil is a more affordable option than other oils and has a long shelf life. If you’re looking for a healthier alternative to deep-frying french fries, canola oil is a great choice.
