Yes, you can use olive oil for high heat cooking, but with caution. Olive oil can be used for sautéing and high-heat cooking as long as the temperature is kept safe, despite having a lower smoke point than some other oils.
Extra virgin olive oil has a smoke point ranging from 375°F to 410°F (190°C to 210°C), while refined olive oil has a slightly higher smoke point of about 465°F (240°C). Refined olive oil is better for high-heat cooking, while extra virgin olive oil is best for lower heat or raw uses like dressings.
In my experience, olive oil can handle moderate high heat, such as when sautéing vegetables or searing meat. However, I avoid using it for intense heat methods like deep frying. I use oils with high smoke points like avocado or grapeseed oil, so that the flavor and nutritional quality of the dish are not affected.
Smoke Point: Key Factor for High Heat Cooking
When it comes to high-heat cooking, such as frying, sautéing, or grilling, it’s crucial to choose an oil that can withstand the temperature without breaking down and losing its nutritional value or producing harmful compounds. Olive oil, particularly extra virgin olive oil (EVOO), is often discussed in this context, and the key factor to consider is its smoke point.

The smoke point of an oil is the temperature at which it begins to smoke and break down. At this point, the oil starts to decompose, releasing free radicals and harmful compounds like acrolein, which can give food an unpleasant burnt flavor and pose health risks if inhaled or ingested over time.
Smoke Points of Olive Oil Varieties:
- Extra Virgin Olive Oil (EVOO):
- Smoke Point: 350°F (175°C) to 410°F (210°C), depending on quality and purity.
- Best Use: Medium-heat cooking like sautéing, roasting, and baking, as well as for finishing dishes.
- Consideration: High-quality EVOO has a lower smoke point due to its high content of unrefined nutrients and polyphenols.
- Virgin Olive Oil:
- Smoke Point: Approximately 420°F (215°C).
- Best Use: Higher-heat applications compared to EVOO, but still ideal for medium-heat cooking.
- Consideration: Slightly higher smoke point due to less refinement.
- Refined or Light Olive Oil:
- Smoke Point: 465°F (240°C) to 470°F (243°C).
- Best Use: High-heat cooking, such as frying or grilling.
- Consideration: The refining process removes most of the flavor and some nutrients, resulting in a higher smoke point and a more neutral taste, making it better suited for high-heat applications.
Why Smoke Point Matters for High-Heat Cooking:
- Nutritional Integrity: If olive oil is heated past its smoke point, it not only loses its beneficial nutrients (like antioxidants and healthy fats) but also generates harmful compounds.
- Flavor Maintenance: Overheating can cause the oil to develop an off-flavor, which can negatively affect the taste of your food.
- Health and Safety: Cooking oils that reach their smoke point can release toxic fumes, which may cause irritation to the eyes, throat, and lungs.
