Wood in the microwave?

Microwaveable dishes have been written a lot. One question that keeps cropping up and has gone unanswered, however, is: are wooden boards or wooden dishes also suitable for the microwave? An answer to this can be found in this post.

Wooden board in the microwave

Wooden boards and wooden bowls can be safely put into the microwave. One only has to be aware that wood warms to the same degree as the food to be cooked. Wooden bowls and wooden boards are so hot in the microwave and can hardly be touched.

Wooden bowls and grill function

The only danger is to use the wood in the microwave when the grill function is switched on. The quartz grill of microwaves - but also an infrared grill - can generate very high temperatures. There is a risk that the wood could start to burn. With the grill function switched on, you should therefore give as no wood items in the microwave.

An alternative that is also used for wooden skewers is "watering". Wooden skewers are placed in water for at least 1 to 2 hours before being used. So you can also on the conventional grill. For wooden boards the same applies.

Damage to the wood

Over time, the wood can dry out very much. This is due to the evaporation of residual moisture that is naturally present in the wood (usually around 10 - 20%). After several uses in the microwave, the wood can become brittle and fall apart at the glued areas.


The germs, which otherwise adhere well to wood, are very reliably killed by the high temperatures in the microwave. You can also use the microwave to sterilize its wooden boards at regular intervals. This requires low power and at least 5 - 10 minutes running time to reach sufficiently high temperatures. Turn the board over once.

Tips & Tricks

Microwaveable dishes are generally recognized by the fact that they do not heat up when heated in the microwave itself. This can be tested by placing the dishes empty for a short time (not longer than 20 - 30 seconds !!) at low power in the microwave. If it is warm, it is not suitable. Wood is an exception because it is an organic material.
