EVOO in Cooking: Debunking the Myth of the Low Smoke Point
One of the most persistent myths in cooking is that extra virgin olive oil cannot be used for high-temperature cooking. This is a common but incorrect belief—and the practical consequences of following it are real: those who avoid EVO in cooking often substitute it with refined seed oils, which have a much lower nutritional profile. In this guide, you will find real data, mechanisms, and practical advice on how to use EVO in cooking.
The Myth of the Low Smoke Point: Where It Comes From
The belief that EVO cannot be used in cooking stems from a partial understanding of the concept of "smoke point." The reasoning is: refined sunflower oil has a smoke point of 230°C, while EVO has one of 180-210°C—therefore, sunflower oil is "better" for high-temperature cooking.
The problem is that the smoke point is not the only relevant parameter, and it is probably not even the most important. There are two errors in this reasoning:
- The smoke point of refined oils is high because they have been stripped of everything: Refined seed oils have a high smoke point because the refining process has removed free fatty acids, impurities, and aromatic compounds that degrade with heat. They have also removed beneficial compounds.
- Thermal stability does not depend solely on the smoke point: It depends on oxidation resistance—and here, EVO is superior. Monounsaturated fats (oleic acid) are much more heat-stable than the polyunsaturated fats (linoleic acid, linolenic acid) found in most seed oils. The vitamin E and polyphenols in EVO act as antioxidants that further slow down thermal oxidation.
What Studies Say About Thermal Degradation
Studies that have directly tested the stability of oils in cooking show results that contradict popular narratives:
- ACTA Scientific Study (2018): Comparison of 10 different oils heated to frying temperatures (180°C) for hours. EVO produced the lowest amount of toxic polar compounds (including aldehydes and peroxides) compared to all tested seed oils—including sunflower, corn, and soy. Coconut oil was comparable to EVO.
- Food Chemistry Study (2010): EVO heated to 180°C for 36 consecutive hours maintained levels of polar compounds well below food safety limits, while refined seed oils exceeded them within 8-10 hours.
- Systematic Review (2017): The analysis of available literature concludes that EVO is the most suitable oil for home frying, both for its nutritional profile and its chemical stability at typical home cooking temperatures (150-180°C).
Cooking Temperatures and EVO: A Practical Guide
The smoke point of EVO varies between 180°C and 210°C depending on its quality (the fresher and purer, the higher it is). Typical domestic cooking temperatures:
- Light Sauté: 80-100°C — no problem, well below any critical threshold.
- Stir-frying: 140-160°C — well within the safe zone for EVO.
- Domestic Deep Frying: 160-180°C — within EVO's working range, safe if the temperature is controlled.
- Air Frying: typically 180-200°C — at the higher limit for EVO; a good quality extra virgin oil handles this without issues.
- Grilling and High-Temperature Oven (220°C+): these temperatures exceed EVO's smoke point. For these cooking methods, it's better to use the oil for marinating beforehand and add fresh EVO raw after cooking.
Practical Tips for Cooking with EVO
- Never Overheat: The most important rule is not the type of oil but the temperature. Any oil heated beyond its smoke point and kept there for a long time will produce degradation compounds. With EVO, keep the temperature moderate and do not leave an empty pan on the heat.
- Do Not Reuse Oil After Frying: Each heating cycle reduces quality. For occasional home frying, use fresh oil and dispose of the used oil.
- Use the Right EVO for Each Cooking Method: For frying and sautés, Pertutto Cutrera is the ideal daily blend—good smoke point, balanced fruity flavor, affordable price for generous use. Precious monocultivar oils (Primo DOP, Nocellara) should be reserved for raw applications, where their aromatic complexity is best expressed.
- Adequate Quantity: A common mistake is using too little oil for frying. Small amounts cause more frequent temperature fluctuations and worsen frying quality. The right amount helps maintain a stable temperature.
Frying with Extra Virgin Olive Oil: Good or Bad for You?
Frying with EVO is much healthier than frying with refined seed oils, for two main reasons:
- Fewer Toxic Compounds in Frying: As shown by thermal stability studies, EVO produces fewer aldehydes, peroxides, and acrylamide compared to polyunsaturated seed oils at the same frying temperatures.
- Food Absorbs Less Oil: The rapid formation of a crust on the surface with high-temperature EVO reduces fat absorption in fried food. Foods fried in EVO at the correct temperature absorb less oil than those fried in seed oils.

Frequently Asked Questions
Is olive oil harmful when cooked?
No, if used at appropriate temperatures (up to 180°C) and without prolonged overheating. Studies show that it is among the most thermally stable oils—it produces fewer degradation compounds compared to polyunsaturated seed oils at the same temperatures.
Does EVO lose its benefits when cooked?
Partially. Heat degrades a portion of the polyphenols—the loss depends on temperature and duration. At 180°C for 10-15 minutes (short frying), about 30-40% of polyphenols are lost. Oleic acid and vitamin E are more stable. The practical message: use EVO in cooking without fear, and always add a drizzle raw to maximize bioactive compounds.
Is EVO or avocado oil better for cooking?
Avocado oil has a very high smoke point (270°C) and is rich in oleic acid—it is a valid alternative for high-temperature cooking. But it is significantly more expensive than EVO and has a much more limited body of health evidence. For daily home cooking, a good EVO like Pertutto is the optimal choice for quality, versatility, and value for money.
Can EVO be used in an air fryer?
Yes. Air fryers typically operate between 180°C and 200°C—at the higher limit for EVO but manageable with a quality oil. Spraying or brushing EVO onto food before air frying is the correct technique: little oil is used, distributed evenly, without remaining at high temperatures for extended periods.
