How to Season a New Wood Cutting Board (The Right Way)

A brand new wood cutting board feels solid and looks beautiful right out of the box. But before you put a knife to it, it needs to be seasoned — and if you skip this step, you'll shorten the life of your board, make it harder to clean, and risk cracking over time. Seasoning a new board takes about 15 minutes of active work and a day of patience. Here's exactly how to do it right.

What Does Seasoning Actually Do?

Wood is porous. An untreated board absorbs water readily — from food moisture, from washing, from humidity in the air. This absorption causes the wood fibers to swell and contract repeatedly with every use, which leads to checking (small surface cracks), warping, and eventually splitting along the grain. Seasoning fills those pores with food-safe oil, dramatically reducing how much water the wood can absorb and slowing the swelling-and-shrinking cycle that causes damage.

A well-seasoned board also develops a more resistant surface that resists food staining, is easier to scrub clean, and maintains the visual warmth of the wood over years of use. The difference between a seasoned and unseasoned board after 12 months of daily use is stark — one looks lived-in and beautiful, the other looks battered and dry.

What to Use: Oil Options

Food-grade mineral oil is the standard recommendation and the right choice for initial seasoning. It's inexpensive, completely flavorless and odorless, doesn't go rancid, and penetrates wood effectively. You can find it at any hardware store or pharmacy. Do not use olive oil, vegetable oil, coconut oil, or any culinary oil for seasoning — they contain unsaturated fatty acids that oxidize and go rancid inside the wood, creating off odors and a sticky surface over time.

Once a board is well-saturated with mineral oil, transitioning to a beeswax and MCT oil blend for ongoing maintenance provides additional benefits: beeswax creates a surface layer that beads water more effectively, and MCT oil (medium-chain triglycerides from coconut) doesn't go rancid. This combination is what we use for all our boards and what we recommend for long-term care.

Step-by-Step: First Seasoning

Step 1: Start with a clean, dry board. Your new board should be clean from the workshop, but give it a quick wipe with a dry cloth to remove any dust. The board must be completely dry before you apply oil — wet wood won't absorb oil evenly.

Step 2: Apply oil generously. Pour a substantial amount of mineral oil directly onto the board surface. You want enough to pool slightly. Use a clean cloth, paper towel, or your hands to spread it evenly across the entire surface — top, bottom, and all four sides. Don't be shy with quantity on the first application; a new board is very thirsty.

Step 3: Let it soak in. Set the board on its edge (or propped at a slight angle) and let it absorb for a minimum of 4 hours — overnight is better. You'll likely see that the oil has been mostly absorbed when you return. This is normal and expected.

Step 4: Wipe off excess and repeat. After absorption, wipe off any oil that hasn't soaked in. Then apply a second coat using the same process. For a brand new board, we recommend doing this 3 to 4 times in the first week — each time you apply oil and let it absorb, you're building a deeper reservoir of protection in the wood fibers.

Step 5: Buff with a dry cloth. After your final coat, buff the surface with a clean dry cloth to bring up a slight sheen and remove any surface tackiness. The board is now ready to use.

Ongoing Maintenance

After the initial seasoning, re-oil when the surface starts to look dry and lighter than its normal color — typically every few weeks with daily use, less often if the board is used occasionally. A well-maintained board will look darker, richer, and more beautiful over time rather than fading and drying out. The few minutes it takes to oil a board is the single most effective thing you can do to extend its life by years.
