Using Aluminium Foil in your Microwave
It is safe to use aluminium foil in your microwave as long as you follow these safety guidelines.
As with all metal, microwave energy cannot pass through foil, but provided that you keep the foil
away from the side of the microwave it will not cause sparks and there will not be any damage to your
microwave.
Using foil is a good way of shielding parts of food that you do not want to cook as quickly as others –
perhaps where the food is narrower and would otherwise overcook.
Place the foil over the area you want to shield, taking care that the foil will not touch the sides of the
microwave when the turntable rotates. Only use one piece of foil at a time so that you do not get sparks
between the separate pieces.
Follow these guidelines when using foil in your microwave:
• Remove foil lids from containers before using in the microwave. Some lids are made of card with a foil
covering – these should be removed too. Use a microwave safe transparent lid if possible.
• Stir food during cooking if the container has a lid or film cover.
• Always use the glass turntable.
• Use shallow containers with a large surface area. Do not use containers that are more than 1.25in
(3.5cm) deep.
• Use gloves when handling hot foil containers.
• Do not completely cover food with foil. The microwave energy cannot pass through the foil so the
food will not cook.
• Do not let aluminium foil touch the inside of the microwave.
• Do not use more than one piece of foil in the microwave at the same time.
