Not all olive oils are created equal, and their performance changes dramatically when exposed to varying temperatures. Refined options like light or pure olive oil have a higher smoke point, generally around 465°F (240°C), making them suitable for frying.
Healthy High Heat Olive Oil: Choosing the Right Type for Frying and Searing
While it is true that heating any oil can diminish some of its beneficial compounds, such as the polyphenols found in extra virgin varieties, the core fat structure remains largely stable. When compared to oils high in polyunsaturated fats, such as soybean or corn oil, high-quality olive oil maintains its integrity much better under thermal stress.
Chemical Stability Matters More Than Smoke Point While the smoke point is a useful guideline, modern research suggests that oxidative stability is a more critical factor in determining an oil's suitability for high heat. Techniques like pan-frying vegetables or searing a steak are perfectly safe and effective with extra virgin olive oil.

The key is avoiding overheating past the point where the oil starts to shimmer excessively or smoke. Extra virgin olive oil is the least processed, retaining antioxidants and a low acid content, which contributes to its lower smoke point but superior flavor.
