If you have a beautiful acacia chopping board in your kitchen, you already know it is more than just a bit of wood. Acacia has a rich grain, a lovely warm tone and it can last for years if you treat it well. The secret to keeping it looking and performing its best? Using the right food grade oils for seasoning acacia chopping boards.
Choose the right oil and your board will stay silky smooth, resist stains and avoid cracking. Choose the wrong one and you could end up with sticky residue, strange smells or even a rancid surface. Nobody wants that under their onions.
Why seasoning matters for acacia chopping boards
Acacia is a dense hardwood, which is one of the reasons it is so good for chopping boards. It is naturally water resistant and less prone to deep cuts than softer woods. But it is still wood, which means it has pores that can absorb moisture and food juices if left unprotected.
Seasoning with the best food grade oils does three important jobs:
- Repels water by filling the pores so liquids bead on the surface instead of soaking in
- Reduces staining and smells from things like beetroot, garlic and raw meat juices
- Helps prevent warping and cracking by keeping the wood fibres nourished and more stable
Think of seasoning like moisturiser for your board. A little care every so often keeps it supple and glowing instead of dry and tired.
The golden rule: always choose food grade oils
Whatever you use on your acacia board must be safe to eat. That means food grade oils only. If the label does not clearly state food safe or food grade, it does not go on your chopping board. Simple as that.
There is another rule that is just as important. Avoid oils that go rancid. Many common kitchen oils such as olive, vegetable, sunflower and sesame are drying or semi drying oils. They oxidise, develop off smells and can leave a sticky, gummy surface on your board. Even if you like cooking with them, they are not the best oils for seasoning acacia chopping boards.
The best food grade oils for seasoning acacia chopping boards
So which oils actually work well and keep your board in top condition? Here are the ones we recommend and use on our own Deer & Oak boards.
1. Food grade mineral oil
If you only ever buy one product for your board, make it food grade mineral oil. It is the classic choice for a reason.
- Stable and non drying so it will not go rancid or sticky
- Clear and odourless so it will not change the colour or smell of your acacia
- Penetrates deeply into the wood fibres to protect from the inside out
Look for mineral oil that is specifically labelled as food grade or suitable for chopping boards and worktops. Pharmacy grade mineral oil that is safe as a laxative is also fine. Avoid mineral oils sold for machinery or wood finishing unless they are clearly marked as food safe.
At Deer & Oak we pre oil our acacia range with food safe oils so your board arrives ready to use. Our acacia chopping board sets just need a light top up from time to time depending on how often you use them.
2. Beeswax and mineral oil blends
If you want a slightly more protective finish, a blend of beeswax and mineral oil is an excellent choice. The mineral oil soaks into the acacia while the beeswax forms a soft, water resistant layer on the surface.
These blends are especially good if you use your board for juicy foods like tomatoes or if it lives next to the sink where it is more likely to get splashed. They also leave a lovely gentle sheen that really brings out the acacia grain.
You can buy ready mixed board conditioners or make your own by gently melting pure beeswax and stirring in warm food grade mineral oil. If you do that, keep the ratio roughly one part wax to four parts oil so it is soft enough to buff in easily.
3. Fractionated coconut oil
Coconut oil is one of the few plant based oils that can be safe for wood seasoning, but only in its fractionated form. This is coconut oil that has had the long chain fatty acids removed so it stays liquid at room temperature and is far less likely to go rancid.
It has a few nice advantages:
- Food safe when you buy a culinary grade product
- Non sticky and soaks in well, similar to mineral oil
- Mild scent that usually disappears after buffing
If you prefer to avoid petroleum derived products, fractionated coconut oil can be a good alternative. Just make sure it is clearly labelled as fractionated or MCT oil and is sold for food use, not just cosmetics.
4. Speciality board oils and conditioners
There are many branded chopping board oils on the market. Most of them are simply food grade mineral oil, sometimes with added vitamin E, beeswax or carnauba wax. These can be very handy if you like a ready made solution and a nice tidy bottle in the cupboard.
When you are choosing, check the ingredients list. You are looking for food grade mineral oil as the main ingredient, with optional waxes or natural additives. Avoid anything that lists drying oils like linseed or tung unless the product clearly states it is suitable for food contact surfaces.
Oils to avoid on acacia chopping boards
It is worth repeating because this is where many boards come to a sticky end. Some oils are great for cooking but terrible for seasoning wood.
- Olive oil can smell rancid quite quickly and leave a tacky film
- Vegetable, rapeseed, sunflower and corn oils all oxidise and gum up over time
- Nut oils like walnut or almond can go rancid and may cause issues for anyone with allergies
- Flaxseed and linseed oil are drying oils that harden and can become patchy on chopping surfaces
If it is sold first and foremost as a salad oil, it is usually not the best choice for your acacia board.
How to season your acacia chopping board step by step
Once you have the right oil, the actual seasoning is wonderfully simple. Here is the method we recommend for our own wooden chopping boards.
-
Start with a clean, dry board
Wash your acacia board in warm soapy water, rinse and dry thoroughly with a clean towel. Stand it upright and let it air dry until it feels completely dry to the touch. Never soak it in the sink or put it in the dishwasher. -
Apply a small amount of oil
Pour a teaspoon or two of your chosen food grade oil onto the surface. A little goes a long way. Use a soft, lint free cloth or a piece of kitchen towel to spread it evenly over the whole surface, including the sides and any juice grooves. -
Let the oil soak in
Leave the board lying flat for at least 20 to 30 minutes. For very dry boards or a first seasoning, you can leave it for several hours or overnight. -
Wipe away the excess
After it has soaked, buff the surface with a clean dry cloth to remove any oil that has not been absorbed. The board should feel smooth and nourished, not greasy. -
Repeat if needed
If your acacia looks patchy or still feels dry, repeat the process once or twice more. New boards or older, neglected ones can be surprisingly thirsty.
How often should you oil acacia chopping boards?
This depends on how often you use and wash your board, as well as the climate in your kitchen. As a general guide:
- Heavy daily use: once every 2 to 4 weeks
- Regular use: once a month or so
- Occasional use: every 2 to 3 months
The easiest way to tell is the water test. Sprinkle a few drops of water on the surface. If they bead up nicely, your seasoning is still doing its job. If they soak in and darken the wood straight away, it is time for another oiling.
Extra care tips to keep your board in top shape
Using the best food grade oils for seasoning acacia chopping boards is half the story. A few simple habits will help your board stay beautiful for years.
- Always dry upright so air can circulate around both faces
- Use one side for strong flavours like garlic or raw meat and the other for fruit and bread
- Avoid harsh chemicals like bleach which can dry and damage the wood
- Sanitise gently with a wipe of white vinegar or a sprinkle of coarse salt and lemon, then rinse and dry
If you like to have different boards for meat, veg and serving, our pre oiled carbonised bamboo boards and solid butcher's block are designed with the same care as our acacia range. Seasoned properly, they will all age gracefully together on your worktop.
A quick recap
When you are choosing the best food grade oils for seasoning acacia chopping boards, keep these points in mind:
- Stick to food grade mineral oil, beeswax blends or fractionated coconut oil
- Avoid everyday cooking oils that can go rancid or sticky
- Oil little and often rather than waiting until the board looks very dry
- Always clean and dry your board properly before seasoning
Look after your acacia board and it will reward you with a stable, hygienic cutting surface and a warm, natural presence in your kitchen. A couple of minutes with the right oil every month is a tiny effort for something you use every single day.
