potatoes on shelves. Bake about 45 minutes
at 375 degrees F. (Time will depend on size
and quantity of potatoes.)
1. ALWAYS PREHEAT OVEN FOR A MINIMUM OF 7 MINUTES.
2. Shelf positions - This model has 3 shelves. When cooking larger volume
foods, it may not be appropriate to use all the shelves. Use the shelf positions
that best center the food in the oven.You may use a sheet pan as a drip tray
on the bottom of the oven.

Preheat oven to 325 degrees F. Combine first
three ingredients in casserole dish. Top
casserole with buttered crumbs. Bake at 325
degrees F for 25-30 minutes or until top is
browned.
3. Warming - Set temperatures around 1750F.
2. Reheating - If food is frozen, cook longer at lower temperatures. This will
ensure that food is heated evenly and prevent food fillings from being served
too hot. For proper food safety, be sure that internal temperature of reheated
food reaches at least 1650F.
3. For even cooking - Always space food evenly on your cooking pans, space
pans evenly in the oven, and leave space between shelves for proper air
circulation. This oven can handle up to three standard 1/4 size commercial

RECIPES FOR BAKING
CONVECTION OVEN RECIPE CONVERSION GUIDELINES
Cooking is not an exact science, due to many variables such as size and quantity
of food, temperature of food when first put in the oven, etc. Here are general
guidelines for converting conventional recipes for use in a convection oven.
Option one: Bake at the same temperature that the conventional recipe
recommends, but for less time.
Cheese Cake
1-1/2 Lbs Cream Cheese
1-1/4 Cups Sugar
5 Eggs
Generously grease bottom and sides of 8"x8"x
2" pan or 9" spring form pan. Generously sprinkle
the sides and bottom of baking pan with 1/2 cup
of graham cracker crumbs, cornflake crumbs, or
your favorite cookie crushed into crumbs, and
set aside.
Beat cream cheese until soft and light, adding
sugar 1/4 cup at a time. Continue to beat, adding
eggs, one at a time, and then vanilla.
Preheat oven to 325 degrees F and bake for
about 30-35 minutes.
Option two: Bake for the amount of time that the conventional recipe calls
for, but reduce the temperature of the oven by about 25 degrees F. This is the
best option for batter -type items such as muffins and cakes,
1 Tsp Vanilla
Option three: (Best) Bake for a little less time than the conventional recipe
calls for, and also reduce the temperature of the oven.
CONVECTION COOKING TIPS
1.If your original conventional recipe baking time is less than 15 minutes, keep
the original baking time but reduce the temperature by 25-30 degrees F.
2.As with any recipe, check the food about 5-10 minutes before the expected
finish time, due to variables such as the temperature of the food when first
placed in the oven, quantity of food in the oven, your preferred level of
“doneness”, etc.

desired temperature, then turning the temperature control down to the desired
temperature once you put the food in and close the door. This is because an
oven can lose one degree per second that the door is open. The average
loss is about 50 seconds.

oven with radiant heat usually depends on the cooking container rather than
the food. The whole point of convection cooking is to have the heat circulating
around the food. Casserole lids and high-sided cooking pans block the heat
from circulating around the food and prevent the oven from cooking efficiently.
A few rules of thumb for best results:
NOTE: You can adapt your own favorite recipes or use prepackaged cake mixes.
l Cookie sheets – use convection oven
Chocolate Chip Cookies
l Shallow pans (inch sides or so) – use convection oven
l Anything covered (including roasting bags) – use conventional oven
3/4 Cup Butter
3/4 Cup White Sugar
3/4 Cup Brown Sugar
1 Egg
1 Tsp Vanilla
3 Tbsp Milk
Cream butter and sugar together. Beat in eggs,
vanilla and salt. Sift dry ingredients together and
add to the batter, stirring with each addition.
Stir in chocolate pieces. Drop a full teaspoon of
batter for each cookie on very lightly greased
cookie sheet. Preheat oven to 300 degrees F,
then bake 8-12 minutes.
l
Deep roasting pans – use conventional oven (Exception : In a convection
oven, you can roast meats like turkey, beef or lamb in roasting pans
that have inch-and-a-half-high sides if you elevate the meat on a rack,
which you should probably do anyway. Or else, use the Roastisserie!)
7.If items such as cakes with runny batter, muffins, or cookies are baking
unevenly, it is generally because the baking temperature is too high or the
oven was not preheated long enough before baking.
