Glass jars and bottles — Regular glass is too
thin to be used in a microwave. It can shatter
and cause damage and injury.
Paper bags — These are a fire hazard, except
for popcorn bags that are designed for
Styrofoam plates and cups — These can melt
and leave an unhealthy residue on food.
Plastic storage and food containers —
Your microwave makes cooking easier than
conventional cooking, provided you keep these
considerations in mind:
Stir foods such as casseroles and vegetables
while cooking to distribute heat evenly. Food at
the outside of the dish absorbs more energy
and heats more quickly, so stir from the outside
to the center. The oven will turn off when you
open the door to stir your food.
Arrange unevenly shaped foods, such as
chicken pieces or chops, with the thicker,
meatier parts toward the outside of the turntable
where they receive more microwave energy. To
prevent overcooking, place delicate areas, such
as asparagus tips, toward the center of the
Shield food with narrow strips of aluminum foil
to prevent overcooking. Areas that need
shielding include poultry wing tips, the ends of
poultry legs, and corners of square baking
dishes. Use only small amounts of aluminum
foil. Larger amounts can damage your oven.
Containers such as margarine tubs can melt in
Metal utensils — These can damage your oven.
Remove all metal before cooking.
Should you wish to check if a dish is safe for
microwaving, place the empty dish in the oven
and microwave on HIGH for 30 seconds. A dish
which becomes very hot should not be used.
Turn foods over midway through cooking to
expose all parts to microwave energy. This is
especially important with large foods such as
Foods cooked in the microwave build up
internal heat and continue to cook for a few
minutes after heating stops. Let foods stand to
complete cooking, especially foods such as
cakes and whole vegetables. Roasts need this
time to complete cooking in the center without
overcooking the outer areas. All liquids, such as
soup or hot chocolate, should be shaken or
stirred when cooking is complete. Let liquids
stand a moment before serving. When heating
baby food, stir well at removal and test the
temperature before serving.
molecules. Food that is uneven in moisture
content should be covered or allowed to stand
so that the heat disperses evenly. Add a small
amount of water to dry food to help it cook.
