'You can't cook with extra virgin olive oil' is one of the most stubborn kitchen myths. In reality, extra virgin olive oil is one of the most heat-stable cooking fats. Here's why, and how to use it best.
- Extra virgin olive oil's smoke point is around 190–210 °C, suitable for most home cooking.
- Its monounsaturated fat and antioxidants make it heat-stable, often more than people think.
- For deep, repeated frying at very high heat, a refined olive oil (higher smoke point) can be more economical.
- Polyphenols partly degrade with cooking: keep a raw drizzle for finishing.
The smoke-point myth
You often hear that extra virgin olive oil shouldn't be heated. Yet its smoke point (≈ 190–210 °C depending on quality) covers the vast majority of home cooking: sautéing, stir-frying, roasting, pan-frying, shallow frying. What matters as much as smoke point is the oil's oxidative stability — and here olive oil excels.
Why it's heat-stable
Two reasons: mostly oleic acid (a monounsaturated fat resistant to oxidation) and an abundance of natural antioxidants (polyphenols, vitamin E) that protect the oil during cooking. Frying studies show extra virgin olive oil holds up well, often better than more refined oils that lack antioxidants.
Frying: yes, but wisely
You can fry in extra virgin olive oil: it adds flavour and holds heat. The downsides are cost in large volumes and a pronounced flavour that doesn't suit every dish. For deep, repeated, very-high-heat frying, a refined olive oil (labelled simply 'olive oil') or a neutral high-smoke-point oil can be more practical.
Extra virgin, refined or 'light'?
'Olive oil' (without 'virgin') and 'light' olive oil are refined oils, neutral in taste and without polyphenols: handy for neutral high-heat cooking, but without the benefits of extra virgin. Extra virgin brings flavour, antioxidants and stability: the best choice for most cooking and all raw uses.
The best culinary uses
Use extra virgin to sauté vegetables and aromatics, roast, pan-fry, confit at low temperature, and above all raw: dressings, a finishing drizzle on a hot dish, toast. Reserve a more neutral or refined oil for deep frying and preparations where an olive flavour isn't wanted.
Frequently asked questions
Can you cook with extra virgin olive oil?
Yes. Its smoke point (≈ 190–210 °C) and stability cover most home cooking: sautéing, roasting, pan-frying, shallow frying. It's a myth that it must stay raw.
Can you fry with olive oil?
Yes, extra virgin olive oil holds up well to frying thanks to its antioxidants. For large volumes or very repeated high-heat frying, a refined olive oil can be more economical.
What's the difference between olive oil and extra virgin in cooking?
Extra virgin is unrefined: it brings flavour, polyphenols and good stability. Plain 'olive oil' is refined, neutral and without polyphenols, handy for high-heat cooking without an olive taste.
Does heat destroy olive oil's benefits?
It gradually degrades some polyphenols, but the oil remains a good source of monounsaturated fat. To best preserve antioxidants, keep a raw drizzle for finishing.
Which olive oil for frying?
Extra virgin works for occasional, flavourful frying. For deep, frequent frying, a refined olive oil with a higher smoke point is more practical and economical.
