If you care about keeping a wooden or bamboo cutting board for 5 to 10 years, then no, you shouldn’t use olive oil on a chopping board. Use a food safe mineral oil or board conditioner instead, especially on boards like the Deer & Oak 45x35cm Large Bamboo Board or 45x35cm Large Acacia Board, which are pre oiled with the correct type of oil.
Can you use olive oil on chopping board surfaces at all?
Olive oil is technically food safe, so it won’t poison anyone if it touches your kitchen board. The problem is what happens after a few days or weeks. Olive oil is a drying, organic oil. On a porous cutting board it can:
- Turn sticky and tacky in 3 to 7 days
- Develop a sour or rancid smell within a few weeks
- Trap food particles in the surface, making cleaning harder
- Encourage uneven staining and soft patches in the grain
So while you can technically use olive oil on a chopping board, if you want a board that stays smooth, neutral smelling and safe for daily food prep, you should not. A neutral, non drying oil such as board conditioner or food grade mineral oil is the better option for long term care.
Why olive oil is a poor choice for a cutting board
When you pour olive oil into a frying pan, you expect it to heat, darken and eventually burn. The same thing happens more slowly inside a wooden or bamboo chopping board. The oil oxidises, thickens and goes off.
On a 45x35cm board, just 10 to 15 ml of olive oil worked into the surface can start to smell within a month, especially if the board lives near the hob. That rancid odour then transfers to bread, cheese and fruit. It is not harmful in small amounts, but it is unpleasant and hard to remove without sanding.
Olive oil also encourages patchy absorption. Some parts of the grain soak up more, which can cause slight cupping or raised fibres over time. If you have a heavier board like the Deer & Oak Large Acacia Board 45x35cm, 2.1kg, that movement is slower, but it still adds stress to the timber.
What to use instead of olive oil on a kitchen board
For a wooden or bamboo cutting board, you want an oil that:
- Stays liquid inside the fibres
- Does not go rancid or smell
- Is completely food safe
- Repels water and stains
The two best options are:
- Food grade mineral oil often sold as chopping board oil or butcher block oil. It has no flavour, no smell and does not dry out in the same way as olive oil.
- Board conditioner usually a mix of mineral oil and natural waxes such as beeswax or carnauba. This gives extra protection, especially on larger boards used daily.
All Deer & Oak boards are pre treated with food safe oil so they arrive ready to use. You can see the full range of wooden and bamboo chopping boards if you’re starting fresh with a new kitchen board.
How to oil a chopping board the right way
If you’ve ever wiped olive oil across a board and wondered why it felt greasy for days, the method is usually to blame as much as the oil. Here’s a simple 10 minute routine that works on both bamboo and hardwood boards.
1. Clean and dry the board
- Wash with hot water and a small amount of washing up liquid
- Scrub across the grain, especially after raw meat
- Rinse and stand the board on its side to dry for at least 6 hours
2. Apply a food safe oil, not olive oil
- Pour 5 to 10 ml of board oil onto a 38x28cm board, or 10 to 15 ml on a 45x35cm board
- Use a lint free cloth or paper towel to spread the oil over both faces and the edges
- Work with the grain until the whole chopping board has a light sheen
3. Let it soak
- Leave the board flat for 20 to 30 minutes
- If any dry patches appear, add a teaspoon more oil to those areas
4. Wipe off the excess
- Buff the surface with a clean, dry cloth until it feels smooth, not greasy
- Stand the board on its side and leave it overnight before heavy use
Repeat this routine every 4 to 6 weeks for a board used daily, or when the surface starts to look pale and dry. With regular care, a quality board can stay in service for 5 to 10 years.
Can you rescue a chopping board that already has olive oil on it?
If you’ve already used olive oil on your kitchen board, you do not always need to throw it away. The fix depends on how far things have gone.
-
No smell, just slight tackiness
Wash with hot water and washing up liquid twice, dry for 24 hours, then oil correctly with mineral oil. Repeat the wash and oil cycle 2 or 3 times over a month to dilute the olive oil inside the grain. -
Noticeable smell or sticky patches
Lightly sand the surface with 180 to 240 grit sandpaper, wipe away dust, then re oil with board oil. On a 45x35cm board you might remove 0.5 mm of thickness, which is usually fine. -
Deep rancid smell and dark stains
At this point, replacing the board is often safer and less time consuming, especially for raw meat prep.
If you prefer to start with a clean slate, a pre oiled board such as the Deer & Oak Bamboo Double Pack (45x35cm and 38x28cm) gives you two sizes ready to use straight from the box.

Product problem guide: which chopping board for your kitchen?
Different chopping boards solve slightly different problems. Linking the right board to the way you cook makes care and oiling much simpler.
-
Problem: Small, light board sliding around and soaking up water
Solution: Upgrade to a heavier board like the Large Acacia Board 45x35cm, 2.1kg which sits firmly and holds oil more evenly. -
Problem: One board for everything, cross contamination worries
Solution: Use a two board system with the Bamboo Double Pack 45x35cm + 38x28cm. Keep one for raw meat and fish, the other for bread, fruit and cheese. -
Problem: Dark stains showing on a pale board
Solution: Choose a darker finish like the Carbonised Bamboo Board 45x35cm, which hides light staining better when correctly oiled.

Who this is for and who it is not for
Ideal for cooks who want a wooden or bamboo chopping board to last several years, are happy to oil it every month or two, and prefer natural materials to plastic. If you care about flavour, smell and the feel of your kitchen board under a knife, choosing the right oil matters.
Not recommended for anyone who wants a completely maintenance free board, frequently puts boards in the dishwasher, or prefers ultra thin plastic mats they can replace every few months. In those cases, worrying about olive oil on a chopping board is less important than simple hygiene and replacement.
FAQ: can you use olive oil on chopping board surfaces?
Q: Why is olive oil bad for a chopping board?
A: Olive oil oxidises inside the wood or bamboo, which makes it sticky and eventually rancid. That smell can transfer to food and is very hard to remove without sanding. It also does not repel water as effectively as mineral oil, so the board can swell and dry unevenly.
Q: Can I use olive oil once in an emergency and switch later?
A: If you use a very small amount once, clean the board well and start using food grade mineral oil, you can usually avoid long term problems. The key is not to keep topping up with olive oil, as repeated coats build up and are more likely to go rancid.
Q: Which oil should I buy for my Deer & Oak cutting board?
A: Look for a bottle labelled food safe mineral oil, chopping board oil or butcher block oil with no added scent. For extra protection, especially on larger 45x35cm boards, a conditioner that combines mineral oil with beeswax or carnauba wax works very well.
Q: How often should I oil my kitchen board?
A: For a board used every day, oiling every 4 to 6 weeks is usually enough. If the surface looks dry, feels rough or absorbs water quickly, give it a fresh coat sooner. Boards used only at weekends may only need oiling every 2 to 3 months.
Closing thoughts and specific board recommendation
So, can you use olive oil on a chopping board? You can, but if you want a board that stays smooth, neutral and reliable for 5 to 10 years, you should not. A simple bottle of food safe mineral oil and 10 minutes of care each month will do a far better job.
If you’re upgrading your kitchen board, a practical starting point is the Deer & Oak Bamboo Double Pack DNO-BCB-2PK. With a 45x35cm board for mains and a 38x28cm board for fruit and bread, it supports a two board system that keeps raw and cooked foods separate and makes oiling more manageable. You can find it on Amazon UK or browse all boards and sets on the Deer & Oak chopping board sets page.
