Using metal utensils in a microwave oven is generally not recommended, whether you are using it in microwave mode or convection mode. Metal can reflect and concentrate the microwave energy, which can lead to sparking, arcing, and potential damage to the oven or the utensil itself. Moreover, metal in the microwave can cause hot spots that may lead to uneven cooking or even fire hazards.
In microwave mode, using any type of metal utensil is unsafe. However, some microwave-safe dishes and cookware with small amounts of metal (such as those with metallic trim or coatings) have been designed to avoid sparking. Always check the manufacturer's guidelines for any cookware you plan to use in the microwave.
In convection mode, the microwave oven operates differently. It uses a heating element and a fan to circulate hot air, similar to a traditional oven. While convection mode can be used with certain types of metal cookware, it's essential to follow the manufacturer's instructions and guidelines for your specific microwave model.
Most convection microwave ovens come with a metal rack or tray designed specifically for convection cooking. These metal accessories are safe to use because they are designed to work with the convection heating system without causing sparking or arcing.
When using a convection microwave oven, it's best to use microwave-safe cookware made of materials like glass, ceramic, microwave-safe plastics, or specially designed convection microwave-safe metal accessories. Always refer to your microwave oven's user manual for recommendations on suitable cookware and usage instructions to ensure safe and effective cooking.
