If you want your bamboo chopping board to last 5 to 10 years, the single most important step is seasoning it with food safe oil for 10 to 15 minutes before first use, then topping up once a month. Seasoning seals the eco-friendly moso bamboo, helps prevent cracking and warping, and keeps your kitchen board safer and easier to clean.
How to season a bamboo chopping board in 6 simple steps
This method works for any bamboo cutting board, including Deer & Oak moso bamboo boards like the 45x35cm Large Bamboo Board and the 38x28cm Medium Bamboo Board.
1. Choose the right oil
Always use a food safe, non drying oil that will not go rancid. Good options are:
- Food grade mineral oil
- Specialist chopping board oil or conditioner
Avoid olive oil, vegetable oil and nut oils because they can turn sticky and smell unpleasant after a few weeks.
2. Clean and dry the bamboo board
- Wash the board with warm water and a small amount of mild washing up liquid.
- Rinse thoroughly so there is no soap left on the surface.
- Dry with a clean tea towel, then leave it to air dry standing upright for at least 2 hours until the bamboo feels completely dry.
Never soak a bamboo chopping board or put it in the dishwasher. Prolonged water exposure swells the fibres and shortens the life of the board.
3. Apply a measured amount of oil
For a standard 45x35cm kitchen board you will usually need about 2 to 3 teaspoons of oil per side. For a smaller 38x28cm board, 1 to 2 teaspoons per side is normally enough.
- Pour a small pool of oil in the centre of the board.
- Use a soft lint free cloth or a piece of kitchen roll folded into a pad.
- Work the oil over the whole surface, including the edges and any juice grooves.
The bamboo should look evenly glossy but not have puddles of oil sitting on top.
4. Let the moso bamboo absorb the oil
Leave the oiled board lying flat for 10 to 20 minutes so the oil can soak into the bamboo fibres. For a new board that feels quite dry, 30 minutes is even better.
If you are seasoning a thicker carbonised bamboo board, such as the 45x35cm Deer & Oak Carbonised Bamboo Board, expect it to absorb slightly more oil on the first treatment.
5. Wipe off any excess
- After soaking time, use a clean dry cloth to wipe away any remaining surface oil.
- The board should feel smooth and nourished, not greasy.
- Stand the board upright in a rack or against a wall for at least 1 hour before putting it away.
6. Repeat for the first week
For brand new bamboo chopping boards, a simple rule works well:
- Season once a day for the first 3 days
- Then once a week for the next 3 weeks
- After that, once a month or whenever the surface looks dry or rough
With this routine, a quality moso bamboo board can stay in daily use for 5 to 10 years in a busy family kitchen.
Why seasoning matters for eco-friendly bamboo boards
Moso bamboo is naturally dense and fast growing, which makes it a very eco-friendly material for kitchen boards. However, it is still a natural fibre that can dry out if it is not protected.
Seasoning your bamboo cutting board helps with three specific problems:
-
Cracking and splitting
Unseasoned boards lose moisture faster from the surface than from the centre. That difference in moisture can lead to hairline cracks after 6 to 12 months. A thin layer of oil slows moisture loss and keeps the board more stable. -
Warping
When one side stays wetter than the other, boards can warp or cup. Oiling both sides evenly reduces this risk, especially on larger boards like a 45x35cm butcher style board. -
Staining and odours
Raw bamboo fibres can soak up beetroot, turmeric, onion and garlic. Seasoning fills the surface pores so stains and smells are less likely to linger.
Pre oiled boards, such as the Deer & Oak bamboo and acacia range, arrive already seasoned, but a light top up oil once a month will keep the protection in place.
How often should you season a bamboo cutting board?
You can use three simple checks to decide when to re season your board:
- Water test: Sprinkle a teaspoon of water on the board. If the droplets sit on the surface, the seasoning is still working. If they soak in within 10 seconds, it is time to oil.
- Touch test: Run your fingers across the board. If it feels rough or slightly furry, the fibres are drying and need oil.
- Colour test: A well seasoned board has a warm, even tone. If the surface has pale, dry looking patches, those areas need attention.
For most home cooks who use a board once or twice a day, monthly seasoning is enough. If you cook 3 or 4 meals a day or run a small food business from home, every 2 weeks is more realistic.
Step by step seasoning example with Deer & Oak boards
Here is how you might season two boards at once using the Deer & Oak Bamboo Double Pack:
- Place the 45x35cm Large Bamboo Board and the 38x28cm Medium Bamboo Board on a clean worktop.
- Use about 4 teaspoons of oil in total for both sides of both boards.
- Set a timer for 20 minutes to allow absorption.
- Wipe off excess and stand both boards upright for at least 1 hour.
This simple 30 minute routine once a month protects 3.0kg of eco-friendly moso bamboo and keeps your main kitchen boards ready for daily chopping, slicing and serving.

Frequently asked questions
Q: Do I really need to season a new bamboo chopping board?
A: Yes, even pre oiled boards benefit from a fresh coat of oil once they arrive in your kitchen. Transport and storage can dry the surface slightly. A 10 minute seasoning before first use helps the moso bamboo adapt to your home humidity and reduces the risk of early cracking.
Q: Which oil is safest for seasoning a bamboo cutting board?
A: Food grade mineral oil or a dedicated board conditioner is the safest option. These products are tasteless, odourless and do not go rancid, even after months. Avoid cooking oils like olive or sunflower oil, as they can oxidise and leave sticky patches or off smells on your kitchen board.
Q: How long should I leave the oil on the board before wiping?
A: For most bamboo boards, 15 to 20 minutes is ideal for the first coat. If the surface looks dry after 10 minutes, you can add a second light coat and wait another 10 minutes. After that, wipe away any excess so the board feels smooth, then let it stand upright for at least 1 hour before storing.
Q: What if my bamboo board has already started to crack?
A: Small hairline cracks can often be stabilised with regular seasoning so they do not spread. Clean the board, let it dry fully, then oil both sides once a day for 3 days. If cracks are wider than 1 mm or food particles are getting trapped, it is safer to replace the board and season the new one from day one.
Recommended Deer & Oak boards for easy seasoning
