If you want a straight answer: the best oil for seasoning a wooden cutting board is food grade mineral oil, applied in 3 to 4 thin coats and topped with a beeswax and mineral oil conditioner every 4 to 6 weeks. For Deer & Oak boards like our 45x35cm Large Bamboo Board or 45x35cm Large Acacia Board, this routine keeps them water resistant, smooth and looking new for 5 to 10 years of regular home use.
What is the best oil for seasoning a wooden cutting board?
For a wooden or bamboo cutting board, the best oil must be food safe, non drying and non rancid. That rules out most everyday cooking oils.
The three most reliable options are:
- Food grade mineral oil (top choice for most kitchens)
- Specialist cutting board oil (usually mineral oil with added vitamin E)
- Beeswax and mineral oil conditioner (for a final protective layer)
On Deer & Oak boards such as our Large Bamboo Board 45x35cm and Large Acacia Board 45x35cm, we pre oil with a food grade mineral oil during production, because it penetrates deeply and does not go sticky or sour over time.
By contrast, olive oil, sunflower oil and other vegetable oils can oxidise and turn rancid within 2 to 3 months, leaving smells and sticky patches. That is why they are not the best oil for seasoning a wooden cutting board, even if you already have them in your cupboard.
Why mineral oil works best on bamboo and hardwood boards
Whether you use a Moso bamboo board or a solid acacia board, the wood is full of tiny pores. Mineral oil has a low viscosity and small molecules that can sink into those pores, which helps in three ways:
- Water resistance : a well oiled board absorbs less water, which reduces warping and cracking by up to 60 to 70 percent compared with a dry board.
- Stain resistance : oil saturation makes it harder for beetroot, turmeric or meat juices to soak in and leave dark marks.
- Smoother cutting surface : oil slightly plumps the fibres so knife marks stay shallow and the surface feels silky to the touch.
Our Deer & Oak chopping boards are designed with this in mind. The Large Acacia Board DNO-ACB-LG at 45x35cm and 2.1kg is dense enough to handle daily chopping, while still taking up oil evenly along the grain.
Step by step: how to season a wooden cutting board
Here is a simple, repeatable method you can use on any Deer & Oak board, from our Medium Bamboo Board 38x28cm to the Carbonised Bamboo Board 45x35cm.
1. Clean and dry the board fully
- Wash both sides with warm water and a small amount of mild washing up liquid.
- Rinse and stand the board upright so air reaches both faces.
- Let it dry for at least 12 hours, or overnight, before oiling.
2. Apply the first coat of oil
- Pour about 1 to 2 teaspoons of food grade mineral oil onto the board.
- Spread it with a lint free cloth or paper towel, working with the grain.
- Cover both sides and all four edges. A 45x35cm board usually needs 5 to 8ml per coat.
3. Let the oil soak in
- Leave the board flat for 20 to 30 minutes so the oil can penetrate.
- If any shiny wet patches remain after 30 minutes, wipe them lightly so the surface is only slightly damp, not greasy.
4. Repeat 2 or 3 more times
- For a brand new or very dry board, apply 3 to 4 coats in total.
- For a regularly maintained board, 1 to 2 coats every month is usually enough.
5. Finish with a wax conditioner (optional but helpful)
- Rub a small amount of beeswax and mineral oil conditioner over the surface.
- Buff after 15 minutes with a clean cloth until the board feels dry and silky.
Used this way, our pre oiled bamboo and acacia boards can stay in good condition for 8 to 10 years in a typical 2 to 4 person household.
How often should you oil a wooden cutting board?
Frequency depends on how often you cook and on your kitchen climate.
- Heavy daily use (2 to 3 meals a day) : oil every 2 to 3 weeks.
- Moderate use (3 to 5 times a week) : oil every 4 to 6 weeks.
- Occasional use : oil every 2 to 3 months.
An easy test is the water droplet test. Sprinkle a few drops of water on the board. If they bead up for at least 60 seconds, your seasoning is still working. If they soak in within 10 to 15 seconds, it is time to re oil.
Oils you should not use on wooden cutting boards
Some oils cause more harm than good. To keep your board safe and odour free, avoid:
- Olive oil : can go rancid in 4 to 8 weeks on the board, especially in warm kitchens.
- Sunflower, rapeseed, vegetable and nut oils : also prone to rancidity and can leave sticky patches.
- Flavoured oils : garlic or chilli oils can leave strong smells that transfer to food.
Some people do use walnut or coconut oil, but these are not ideal if anyone in the home has nut allergies, and they can be less predictable in cooler or very warm rooms. For most households, a simple food grade mineral oil is the safest and most consistent choice.
How board material affects seasoning
Different woods absorb oil at different rates. At Deer & Oak we use Moso bamboo, carbonised bamboo and acacia wood across our range.
- Moso bamboo (for example our Large Bamboo Board DNO-BCB-LG, 45x35cm, 1.8kg) is naturally dense and needs a bit less oil. Two coats every 4 to 6 weeks usually keeps it well protected.
- Carbonised bamboo (DNO-CBB-LG, 45x35cm, 1.9kg) has been heat treated, which slightly opens the fibres. It often benefits from 3 coats during the first seasoning.
- Acacia wood (DNO-ACB-LG, 45x35cm, 2.1kg) is rich and slightly more porous, so it responds very well to regular oiling and develops a deeper colour over the first 6 to 12 months.
Whichever you choose, the best oil for seasoning a wooden cutting board in all three materials remains the same: a neutral, food safe mineral oil, ideally paired with a beeswax conditioner.

Who this is for & who it is not for
Ideal for
- Home cooks who use a wooden or bamboo board at least 3 times a week and want it to last for years rather than months.
- People who own or plan to buy a Deer & Oak bamboo board set, a carbonised bamboo board or an acacia chopping board and want clear care instructions.
- Anyone who prefers natural materials and is happy to spend 10 to 15 minutes once a month on board maintenance.
Not recommended for
- People who always put boards in the dishwasher and do not want any hand care routine.
- Commercial kitchens that need heavy duty plastic boards that can be sanitised at 80°C or higher every day.
- Households with severe nut allergies who are considering nut based oils instead of mineral oil. In that case, stick to certified food grade mineral oil only.
FAQ
Q: Can I use olive oil instead of mineral oil on my wooden cutting board?
A: It is not a good idea. Olive oil and most other cooking oils can oxidise and turn rancid within 1 to 2 months on the board, especially in a warm kitchen. This can create unpleasant smells and a sticky surface, so a neutral food grade mineral oil is a safer long term choice.
Q: How long should I let the oil soak into the board?
A: For each coat, let the oil sit for around 20 to 30 minutes. If the board still looks very wet after that time, wipe away the excess so the surface feels lightly moisturised instead of greasy. Then you can repeat with the next coat if the wood still looks dry.
Q: Do I need to oil both sides of the cutting board?
A: Yes, you should always oil both faces and all edges. Treating only one side can encourage uneven moisture absorption, which increases the chance of warping over time. A balanced approach keeps the board flatter and more stable.
Q: Will seasoning remove knife marks from my board?
A: Seasoning will not remove deep knife cuts, but it will make shallow marks less visible and help prevent new ones from tearing the grain. On boards like the Deer & Oak Large Acacia Board, regular oiling every 4 weeks keeps the surface smoother so knife marks stay finer and easier to clean.
Recommended Deer & Oak boards and where to buy
If you are ready to put this into practice, two boards respond especially well to a regular seasoning routine with food grade mineral oil:
- Large Bamboo Board (DNO-BCB-LG, 45x35cm, 1.8kg) : a generous prep surface that stays light and easy to move, ideal if you cook 4 to 6 times a week.
- Large Acacia Board (DNO-ACB-LG, 45x35cm, 2.1kg) : a weightier board suited to meat prep and serving, with rich grain that deepens in colour as you oil it.
You can explore our full range of pre oiled boards on the Deer & Oak site under bestselling chopping boards, or pick up specific sets on Amazon such as the Bamboo Double Pack (45x35cm + 38x28cm) or the Premium Butcher's Block.
Whichever size you choose, pairing your board with the right mineral oil and a simple monthly routine is the single most effective way to keep it safe, stable and enjoyable to use for many years.
