Properly prepare for the amount of food you are cooking and
the initial temperature. When cooking large
quantities of food it is more effective to divide it into
smaller portions for cooking than it is to heat a large amount
for longer.
Make sure that frozen food has been completely thawed
before cooking; incomplete thawing will result in uneven
cooking. Cook food immediately after defrosting.
Cover food with a microwave-safe lid or plastic wrap that
does not touch the food. Covering food helps cook food more
evenly. Make sure to leave a small gap in the cover so that
steam can escape.
Set food items in a single layer on a microwave oven safe
container/plate for even cooking.
Stir food several times during cooking to ensure that the
heat is distributed evenly.
Follow the cooking instructions on the food's packaging. As
different microwaves cook at different rates remember to adjust
the cooking times based on the power of your microwave as most
foods packaging directions are for a specific wattage and
cooking time.
Make sure that you wait the proper amount of “standing”
time after cooking. Standing time allows the cooking process to
complete allowing for better heat distribution within the food.
