Can I use olive oil for deep frying?
Smoke Point and Suitability
Olive oil's smoke point varies: extra virgin olive oil typically smokes around 375°F (190°C), while regular or light olive oil can go up to 465°F (240°C). Deep frying usually happens between 350°F and 375°F, so extra virgin is borderline and may smoke or impart flavors.
For deep frying, choose regular or light olive oil, which has a higher smoke point and milder taste. Even then, the oil breaks down faster than dedicated frying oils, so it's best for occasional use.
- Extra virgin: smoke point ~375°F
- Light/regular: smoke point ~465°F
- Best for occasional frying
Cost and Practicality
Olive oil is much more expensive than canola, peanut, or vegetable oil. Deep frying requires a lot of oil, so using olive oil can be costly. Also, olive oil can impart a distinct flavor that may not suit all fried foods.
If you do fry with olive oil, keep the temperature steady and don't reuse it more than once or twice. Strain it after cooling and store in a cool, dark place. For frequent deep frying, a neutral oil is more economical and neutral in taste.
- Olive oil is costly for large batches
- Flavor may transfer to food
- Reuse at most once or twice
Common mistakes
- Using extra virgin olive oil for high-heat frying; it can smoke and taste bitter.
- Reusing olive oil many times; it degrades faster than other oils.
- Assuming all olive oils have the same smoke point; light olive oil is better for frying.
