MICROWAVE COOKING TIPS
Density of Food
Light, porous food such as cakes and breads cook 
more quickly than heavy, dense foods such as 
roasts and casseroles. You must take care when 
microwaving porous food so that the outer edges do 
not become dry and brittle.
Height of Food
The upper portion of tall foods, particularly roasts, will 
cook more quickly than the lower portion.
Therefore, it is wise to turn tall food several times 
during cooking.
Moisture Content of Food
Because the heat generated from microwaves 
causes moisture to evaporate, relatively dry food 
such as roasts and some vegetables should either 
be sprinkled with water prior to cooking or covered to 
retain moisture.
Bone and Fat Content of Food
Bones conduct heat and fat cooks more quickly than 
meat. Care must be taken when cooking bony or fatty 
cuts of meat in order to prevent unevenly cooked or 
overcooked meat.
Quantity of Food
The number of microwaves in your oven remains 
constant regardless of how much food is being 
cooked. Therefore, the more food you place in 
the oven, the longer the required cooking time. 
Remember to decrease cooking times by at least one 
third when halving a recipe.
Shape of Food
Microwaves penetrate only about 3/4 of an inch (2 
cm) into food. The interior portion of thick foods is 
cooked as the heat generated on the outside travels 
inward. Only the outer edge of food is cooked by 
microwave energy; the rest is cooked by conduction. 
The worst possible shape for a food that is to be 
microwaved is a thick square.
The corners will burn long before the center is even 
warm. Round thin foods and ring-shaped foods cook 
most successfully in the microwave.
Covering
A cover traps heat and steam which causes food to 
cook more quickly. Use a lid or microwave cling film 
with a corner folded back to prevent splitting.
Covering with Parchment Paper
Parchment paper (not waxed paper) is microwave 
safe. Because it makes a looser cover than a lid or 
clingfilm, greaseproof paper allows the food to dry out 
slightly.
Stirring
Stirring is one of the most important of all microwaving 
techniques. In conventional cooking, food is stirred for 
the purpose of blending. Microwaved food, however, 
is stirred in order to spread and redistribute heat. 
Always stir from the outside towards the centre as the 
outside of the food heats first.
Placing Thicker Portions Facing Outward
Place thicker cuts or portions of meat, poultry, and 
fish toward the outer edge of the baking dish so they 
absorb the most microwave energy and the food 
cooks more evenly.
Shielding
Strips of aluminium foil (which block microwaves) 
can be placed over the corners or edges of square 
and rectangular foods to prevent those portions from 
overcooking. Never use too much foil and make sure 
the foil is secured to the dish or it may cause arcing in 
the oven especially if the foil passes too closely to the 
walls of the oven during rotation.
Elevating
Thick or dense foods can be elevated so that 
microwaves can be absorbed by the underside and 
center of the foods.
Piercing
Foods enclosed in a shell, skin or membrane are 
likely to burst in the oven unless they are pierced 
prior to cooking. Such foods include yolks and whites 
of eggs, clams, oysters, potatoes, and other whole 
vegetables and fruits.
Testing if Cooked
Microwaves cook food quickly, so test food for 
doneness frequently. Some foods are left in the 
microwave until completely cooked, but most foods, 
including meats and poultry, should be removed from 
the oven while still slightly undercooked and allowed 
to finish cooking during standing time. The internal 
temperature of foods will rise between 5 °F (3 °C) and 
15 °F (8 °C) during standing time.
Standing Time
Foods are often allowed to stand for 3 to 10 minutes 
after being removed from the oven. Usually the foods 
are covered during standing time to retain heat unless 
they are supposed to be dry in texture. Standing 
allows foods to finish cooking and also helps flavors 
blend and develop.
