Most people know that olive oil has many health benefits and that using it in low-heat cooking and for finishing enhances the flavors in foods, but what about high-heat cooking like frying?
A recent study revealed that frying vegetables in extra virgin olive oil was actually healthier than boiling them. It makes sense: Not only do you get to keep the nutrients in the veggies instead of pouring them down the drain, but the olive oil helps your body absorb them (not to mention packing quite a few helpful components of its own, like cancer-fighting polyphenols).

So let’s dispel some of the long-held misconceptions about using olive oil in high-temperature methods such as frying and sautéing.See Also: Cooking With Extra Virgin Olive Oil
Although pan-frying, deep-frying, stir-frying and sautéing are different stovetop methods, they all have one thing in common: the temperature of the cooking oil.
The object of these cooking methods is to cook the outside of the food quickly, creating a crispy exterior, while allowing the heat from the oil to penetrate all the way through. In order to accomplish this, the oil must reach a temperature of 350°F (177°C) to 370°F (188°C) before introducing the food.
Myth #1: The smoking point of olive oil is too low for frying.
Some cooking oils and fats will reach what is referred to as the smoking point before reaching temperatures required for a good fry. The smoking point is the temperature at which a chemical change takes place resulting in undesirable smoke and flavor. Olive oil is not one of them.See Also: Find the Best Olive Oils for Fried Foods
The smoking point of extra virgin olive oil is somewhere between 380°F (193°C) and 410°F (210°C), depending on the impurities and acid content of the olive oil: the better the quality, the higher the smoking point.
The smoking point of olive oil is well above the temperature required for all but the highest-heat cooking.
Myth #2: Frying temperatures will change olive oil from a ‘good oil’ to a ‘bad oil.’
Cooking fats and oils are considered dietary fats of which there are three types, saturated, trans and unsaturated. The first two are bad, but the third, unsaturated fat, includes olive oil, a healthy plant-derived dietary fat.
The heat required to raise the temperature of olive oil high enough to fry food cannot change the chemical composition of olive oil from a good one to a bad one.
Myth #3: Fried foods absorb cooking oil, making you fat.
Properly fried food will absorb much less cooking oil if the temperature of the oil is hot enough before food is introduced. Otherwise, the food will indeed soak up the oil, producing a soggy, flaccid product. You know, like those oil-soaked fries you had last week from your favorite fast-food chain.
Not only can you fry with extra virgin olive oil, but you should. Frying with EVOO not only satisfies our desire for Southern-fried comfort foods, Asian stir fry, Mexican fajitas and Italian veal piccata, but it does all of that in addition to fulfilling our nutritional requirements for a healthy dietary fat.
