If you have just unboxed a gorgeous new dark chopping board and you are wondering how to season a new carbonised bamboo board properly, you are in exactly the right place. A few minutes of care now will keep it looking beautiful, help protect it from water damage and make food prep smoother for years.
What “seasoning” a carbonised bamboo board actually means
Seasoning is simply the process of saturating the fibres of your board with food safe oil so water and food juices cannot get in as easily. With carbonised bamboo, this step is especially important. The bamboo has been heat treated to achieve that rich caramel colour, which also makes it slightly more porous than natural bamboo.
Proper seasoning:
- Helps prevent cracking and warping
- Reduces staining and lingering smells
- Keeps the surface smooth and kinder to your knives
- Gives the board a deeper, more even colour
Many of our carbonised bamboo boards arrive pre oiled, but a top up at home after a good wash will always help, especially before first use.
What you will need
To season a new carbonised bamboo board properly, gather:
- Food safe mineral oil or a dedicated chopping board oil
- Clean, lint free cloths or paper towels
- Mild washing up liquid
- Warm water
- Optional: a wax conditioner made for wooden boards
A quick note on oil: avoid olive, sunflower or other cooking oils. They can turn sticky and go rancid, which is the last thing you want on a food surface. Mineral oil and board conditioners are designed for this job and stay stable.
Step 1: Give your new board a gentle wash
New boards can arrive with a little factory dust or residue from packaging. Before you think about oiling, give the board a light wash.
How to do it:
- Use a soft sponge, a drop of mild washing up liquid and warm water
- Wipe both sides of the board and the edges
- Rinse quickly under warm running water
- Never soak the board in the sink and never put it in the dishwasher
Pat the board dry with a clean tea towel, then stand it on its side or prop it up so air can circulate around it. Let it dry completely before you start seasoning. If it still feels cool and damp to the touch, give it more time.
Step 2: Apply the first coat of oil
Once your board is bone dry, it is time to feed it. This is where the magic happens.
To season a new carbonised bamboo board properly, you want to be generous with the first coat:
- Pour a small puddle of oil directly onto the surface, about the size of a 10p coin
- Using a cloth or paper towel, work the oil into the board in small circles
- Cover the entire face of the board, paying extra attention to any end grain and the edges
- Flip the board and repeat on the other side
The board should look slightly glossy but not swimming in oil. If you see dry patches appearing straight away, that is the bamboo drinking it in, so add a touch more.
Step 3: Let the oil soak in fully
This bit is easy: walk away. Let the board sit with its first coat for at least an hour. Overnight is even better if you have the patience.
Place it flat on a protected surface or stand it on its side. If you have curious pets or little ones, somewhere out of the way is a good idea. You will notice the surface losing its shine as the oil soaks in. That is exactly what you want.
Step 4: Wipe off any excess
After the soak time, run a clean dry cloth over the whole board. If any patches still feel oily or tacky, buff them until the surface feels silky rather than greasy.
At this stage you should already see a difference. The carbonised bamboo will look richer, with the grain standing out more clearly. If it still looks a bit dry or patchy, do not worry, you are not finished yet.
Step 5: Repeat for 2 to 3 coats
To season a new carbonised bamboo board properly, one coat is rarely enough. Think of the first coat as a base layer. Aim for 2 to 3 coats in total on a brand new board.
For each additional coat:
- Apply a thinner layer of oil on both sides
- Let it soak in for at least 30 to 60 minutes
- Buff off any excess with a clean cloth
How do you know when you are done? When water splashed on the surface beads up rather than soaking in, and the colour looks even across the whole board.
Optional: Finish with a wax conditioner
If you want to take things up a notch, you can finish with a food safe board wax. These are usually a mix of mineral oil and beeswax or plant wax.
Wax adds a slightly harder top layer that helps repel water and gives a soft sheen. Just follow the instructions on the tin: rub on a thin layer, leave it to haze, then buff to a gentle shine. It is not essential, but it does give your board that “just cared for” look for longer.
How often should you re season your carbonised bamboo board?
This depends on how often you use it and how you wash it. As a rule of thumb:
- For daily use: oil lightly once every 2 to 4 weeks
- For occasional use: once every couple of months is usually enough
- If the surface starts to look dry, rough or lighter in patches: it is asking for oil
Trust your eyes and your fingertips. If the board feels thirsty, it probably is.
Everyday care to keep your board in top shape
Seasoning is only half the story. To keep your carbonised bamboo board happy:
- Wash quickly after use with warm soapy water
- Never soak it in the sink or leave it under running water for ages
- Dry straight away with a towel, then air dry upright
- Disinfect gently with a wipe of white vinegar or a paste of bicarbonate of soda for strong smells like garlic
- Use both sides to keep wear even
If you like to keep raw meat separate, consider using one board for meat and another for fruit and veg. That is where a set of bamboo boards in different sizes comes in very handy.
What about other woods and butcher’s blocks?
The same basic method applies to most wooden boards, whether that is carbonised bamboo, natural bamboo, acacia or a chunky block. The main difference is how often each material needs feeding.
For example, our premium butcher's block has more end grain exposed, so it can be even more absorbent. A little extra oil and slightly more frequent seasoning keeps it in top condition.
If you are mixing and matching materials in your kitchen, you can happily use the same food safe oil across all your boards. Just remember that carbonised bamboo tends to show dryness a bit sooner, so keep an eye on it.
Choosing a good carbonised bamboo board to begin with
Of course, seasoning works best when you start with a well made board. Look for:
- Sustainably sourced bamboo
- Smooth, sanded surfaces with no rough patches
- Solid, neatly joined strips with no visible gaps
- Pre oiled finish so the board is protected from day one
Our own range of Deer & Oak boards including carbonised bamboo, natural bamboo, acacia and butcher's blocks are all supplied pre oiled, then ready for you to top up seasoning at home to suit how you cook.
To wrap up
Learning how to season a new carbonised bamboo board properly is not complicated, it just takes a little time and the right oil. Wash gently, dry completely, apply several light coats, let them soak in and repeat whenever the board starts to look or feel dry.
Treat your board well and it will repay you every day, quietly getting on with the job while you focus on the fun part: cooking and sharing good food.
