If you are in the UK and wondering what the best oil for seasoning wooden cutting boards is, the most reliable choice is a 100% food grade mineral oil applied every 4 to 6 weeks. For boards used daily, 10 to 15 ml of mineral oil per side is usually enough to keep a 45x35cm board sealed, hydrated and protected from cracking.
What is the best oil for seasoning wooden cutting boards in the UK?
For most British kitchens, the best oil for seasoning wooden cutting boards is food grade mineral oil that meets UK and EU food contact standards. It is clear, odourless, tasteless and does not go rancid like many cooking oils. When you are caring for a large board such as the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) or Large Acacia Board (45x35cm, 2.1kg), mineral oil creates a stable barrier that can help your board last 5 to 10 years with regular care.
If you want an even tougher finish, you can follow mineral oil with a wax conditioner that contains beeswax or carnauba wax. At Deer & Oak we pre oil our boards with food safe oil so they arrive ready to use, then we recommend topping up with mineral oil at home every few weeks.
Why mineral oil beats common kitchen oils
It is tempting to grab whatever oil is near the hob, but some popular choices cause problems:
- Olive oil, sunflower oil, rapeseed oil: These can oxidise and turn sticky or rancid within 4 to 8 weeks, especially in warm kitchens. That sticky layer can trap smells and bacteria.
- Sesame, walnut, other nut oils: These can also go rancid and may trigger nut allergies. We do not recommend them for shared family boards.
- Coconut oil: More stable than many oils but can still become tacky, and it softens at around 24°C which is common in busy kitchens.
Food grade mineral oil avoids these issues. It sinks into the wood fibres of bamboo and acacia boards, slowing down water absorption and helping to prevent warping and hairline cracks. For example, our extra large bamboo chopping board is pre treated with food safe oil so that the fibres are already sealed before you start cutting.
How to season a wooden cutting board step by step
Whether you own a compact 38x28cm board or a heavy 45x35cm butcher style block, the seasoning method is the same. Here is a simple routine that works well in UK homes.
-
Clean the board
Wash with warm water and a small amount of mild washing up liquid. Scrub both sides, then rinse well. Do not soak the board or leave it sitting in a full sink. -
Dry for at least 12 hours
Stand the board on its edge so air can reach both faces. For a 2.1kg acacia board this is especially important, as heavier boards can hold moisture longer. -
Apply mineral oil
Pour 10 to 15 ml of food grade mineral oil onto the board. For a 45x35cm surface, that is roughly a dessert spoon per side. Use a lint free cloth or a piece of kitchen roll to work the oil into the grain, including the edges and any juice grooves. -
Let it soak
Leave the board flat for 20 to 30 minutes so the oil can absorb. If dry patches appear, add another 5 ml to those areas. -
Buff off the excess
After at least 30 minutes, wipe away any oil that has not soaked in. The surface should feel silky, not greasy. -
Optional wax coat
If you use your board for juicy meats or daily family cooking, add a thin layer of board wax and buff after 15 minutes. This gives extra resistance to water.
Repeat this process every 4 weeks for a heavily used board, or every 6 to 8 weeks for a light use cheese or serving board.
How often should you oil different types of boards?
Different materials and sizes absorb oil at different rates. Here is a simple guide based on our Deer & Oak range.
- Moso bamboo boards such as the Large Bamboo Board (45x35cm, 1.8kg) or Medium Bamboo Board (38x28cm, 1.2kg) usually need oiling every 4 to 6 weeks.
- Carbonised bamboo like our Carbonised Bamboo Board (45x35cm, 1.9kg) is slightly denser and can often go 6 weeks between oilings after the first 3 months.
- Acacia boards including the Large Acacia Board (45x35cm, 2.1kg) and Medium Acacia Board (38x28cm, 1.5kg) are naturally oily but still benefit from a light coat every 6 to 8 weeks.
If a board looks dry, feels rough, or absorbs water marks within 5 seconds, it is time to oil it regardless of the calendar.

Product problem match: which board and oil routine suits you?
Here is how to match the right board and seasoning routine to common kitchen needs.
-
Problem: My board smells and stains after chopping onions or beetroot
Solution: Choose a tightly grained board such as the Deer & Oak Carbonised Bamboo Board (45x35cm, 1.9kg) and oil it monthly with mineral oil. The denser carbonised bamboo and sealed surface make it easier to rinse away strong smells within 30 seconds. -
Problem: My old board has started to crack near the handle
Solution: Swap to a thicker board like the Deer & Oak butcher's block and follow a strict 4 week oiling schedule with mineral oil and wax. The extra thickness and regular seasoning slow down moisture swings that cause those cracks. -
Problem: I cook for a family of four and need separate boards for meat and veg
Solution: Use the Bamboo Double Pack (45x35cm + 38x28cm, 3.0kg) and oil both boards every 4 to 6 weeks. Keep one for raw meat, one for vegetables, and season them on the same day so they wear evenly. -
Problem: I want a serving board that still looks smart after 12 months
Solution: Pick an acacia board such as the Deer & Oak acacia set and oil lightly every 6 to 8 weeks. Acacia's natural oils and the mineral oil finish help it keep its rich colour even with regular washing.
Who this is for and who it is not for
Ideal for: Home cooks in the UK who use wooden or bamboo boards at least twice a week and want them to last 5 to 10 years with simple, regular care. If you own boards between 38x28cm and 45x35cm and are happy to spend 10 minutes every month oiling them with food grade mineral oil, this approach will suit you very well.
Not recommended for: People who prefer dishwasher safe plastic boards, or anyone who knows they will not remember a 4 to 8 week oiling routine. If you need a board you can leave soaking in the sink or run through a dishwasher cycle, a wooden or bamboo board is not the right choice.
FAQ
Q: Can I use olive oil or vegetable oil instead of mineral oil?
A: It is not a good idea. Olive oil, sunflower oil and most vegetable oils can turn rancid in 4 to 8 weeks on a board, especially near the hob where it is warm. Rancid oil smells and can make the surface sticky, so a stable food grade mineral oil is a much safer long term choice.
Q: How do I know when my cutting board needs oiling?
A: Sprinkle a few drops of water on the surface. If the water soaks in within 5 seconds instead of beading on top, the board is dry and ready for oil. You might also notice the colour looking pale or the surface feeling slightly rough compared to when it was new.
Q: Is mineral oil safe for food and for children?
A: Food grade mineral oil that is labelled as suitable for chopping boards is safe when used as directed. It sits inside the wood fibres rather than on your food, and once the board is wiped and buffed there should not be any noticeable residue on the surface.
Q: Do Deer & Oak boards arrive pre oiled or do I need to oil them straight away?
A: Deer & Oak boards arrive pre oiled with food safe oil so you can use them immediately after a quick rinse and dry. We still suggest giving them a first home oiling within the first 2 to 4 weeks, then following the 4 to 8 week schedule depending on how often you cook.
