The oils which should be avoided for cooking are oils like soybean, corn, canola, sunflower, and safflower. These oils have unstable fats and will decimate the nutritional properties of your food. Oh, and they'll give you a big fat health risk in the meantime.
There are definitely other neutral, high-heat oils that work well for frying—canola oil, sunflower oil, peanut oil, avocado oil, and rice bran oil, to name a few—but they tend to cost a whole lot more than generic vegetable oil.
Olive oil actually has a relatively high smoke point and is a safe, reliable option for frying. On top of that, it is one of the healthiest cooking staples around. Olive oil has been named “the healthiest fat on Earth,” in part because of its unique ability to reduce the risk of heart disease.
You Should Deep Fry With Olive Oil

Once in our kitchens, we cook them in our canola-blend oil so you can have them crispy and hot—just the way you like them. Want to hear more about our fry ingredients? Get the down low on how we flavor our fries.
Canola oil is generally considered a “healthy” oil because it is very low in saturated fat (7%). Like olive oil it is high in monounsaturated fat (63%).
Canola oil has a smoke point of 400⁰F while olive oil has a smoke point up to 470⁰F making it a better overall cooking fat for high heat cooking making it more versatile.
While plant-based fats are considered more heart-healthy than animal fats, canola oil is generally believed to be a healthier option because it is lower in saturated fat than vegetable oil.
Heart-healthy oils like canola, corn, olive, peanut, and sunflower oils contain monounsaturated and polyunsaturated fats. They help to lower harmful low-density lipoprotein (LDL) cholesterol and raise healthy high-density lipoprotein (HDL) cholesterol.
Healthiest Stir-Fry Oils
Both canola oil and olive oil are low in unhealthy saturated fats and high in healthy monounsaturated fats. Scientists believe monounsaturated fats help to lower bad cholesterol (LDL) which can clog arteries and lead to heart disease or strokes.
Canola Oil
Benefits: With a high smoke point and neutral flavor, canola oil is excellent for frying chicken. As an added bonus, it has high levels of omega-3 and omega-6 fatty acids, which makes it healthier than other options.
The potatoes we use to make our famous chips generally come from Tassie and Victoria and the high-oleic canola oil we use for cooking them is also Australian-grown.

Canola Oil: Best All-Purpose Oil for Frying
At around 400˚, the smoke point of canola oil is fine for deep-frying—a lot of deep-fried foods needs an oil temperature of around 325˚ to 375˚.
