How Much Olive Oil Should You Use Per Day?

Most people who buy good olive oil make the same mistake: they use it too sparingly. They treat it like an expensive condiment to be rationed, and then the bottle sits on a shelf for eight months slowly going stale.

Here's the truth: olive oil is a cooking staple, not a luxury to save for special occasions. The Mediterranean diet, one of the most studied and celebrated eating patterns in the world, uses olive oil generously, every single day.

This guide answers two practical questions: how much should you actually be using, and what format makes the most sense for your household? By the end you'll know exactly which size to order, and you'll never run out at the wrong moment again.

How Much Olive Oil Should You Use Per Day?

There's no single rule, but here are the most useful benchmarks:

For health benefits: Research consistently points to 1–4 tablespoons (15–60ml) per day as the range where olive oil has a meaningful positive impact on cardiovascular health and inflammation. The landmark PREDIMED study found that people consuming at least 4 tablespoons of extra virgin olive oil daily had significantly lower rates of heart disease.

For cooking: A typical home cook uses 1–2 tablespoons per meal for sautéing, roasting, or dressing — so 2–3 meals a day adds up to 30–90ml of oil used per person, per day.

For finishing/drizzling: Add another teaspoon or two (5–10ml) per person if you're drizzling over dishes, bread, or salads before serving.

Practical daily estimate per person: 20–50ml, depending on how often and how extensively you cook.

A 500ml bottle contains roughly 33 tablespoons of olive oil. Here's how long that lasts in practice:

Household	Daily use estimate	500ml lasts	5L tin lasts
1 person	~20ml/day	~25 days	~ 8 months
2 Person	~40ml/day	~12 days	~ 4 months
Family of 4	~80ml/day	~6 days	~ 2 months
Heavy cooks (4+)	~120ml/day	~4 days	~ 6 weeks

 

The takeaway: a 500ml bottle is great for a single person or someone who cooks occasionally. For couples and families, it disappears fast — and buying a larger format isn't just more economical, it means you always have enough on hand without reordering every week.

Which Format Is Right for You?

500ml bottle, best for:

• Single households or occasional cooks
• Trying a new oil for the first time
• Finishing oil you want to keep fresh and grab easily
• Gifting

500ml tin canister, best for:

• Anyone serious about keeping their oil fresh longer (tin blocks light better than glass)
• Same volume as the bottle but with better shelf stability

5L tin, best for:

• Families or couples who cook daily
• Saving money per litre (the 5L works out significantly cheaper per ml)
• People who've found their go-to oil and want consistent supply

How Long Does Olive Oil Stay Fresh Once Opened?

This is the question that really matters for deciding which size to buy.

An unopened bottle of high-quality extra virgin olive oil stays fresh for 18–24 months from the harvest date. Once opened, the clock speeds up: you want to use it within 3–6 months for optimal flavour and nutritional value.

Exposure to light, heat, and air are the three enemies of olive oil. That's why:

Tin canisters outlast glass bottles once opened, no light gets in

Keep your oil away from the stove, the heat degrades it faster than most people realise

A dark cupboard is ideal, never the windowsill

The practical implication: if you're a single person who cooks lightly, don't buy the 5L. You won't finish it in time. A 500ml every few weeks is actually the smarter move, and it guarantees you're always using fresh oil.

Why Quality Matters More When You Use It Daily

Here's the thing about using 2–4 tablespoons of olive oil every day: the quality of what you're consuming compounds. Over a year that's roughly 10–15 litres of oil passing through your kitchen.

Cheap, blended supermarket oil, often made from old stock, mixed origins, and high acidity, isn't doing you any favours nutritionally. The polyphenols, antioxidants, and healthy fats that make olive oil worth eating are only present in meaningful quantities in fresh, high-quality extra virgin olive oil from a traceable source.

Our Country Kalamata EVOO is sourced directly from producers in Gargaliani, Greece, PDO certified, Koroneiki olive variety, low acidity, current harvest. It's the oil we'd use every day ourselves, and it's what we stock our own kitchens with.

Final Thoughts

Use your olive oil generously and use it fresh. If you're rationing a bottle that's been open for six months, you're not getting the best out of it, and you're probably not using enough to get the real benefits either.

Match the bottle size to your actual usage, store it properly, and reorder before you run out so you're never tempted to grab a supermarket substitute.
