Cooking with the Bosch Convection Oven

Bosch HBL7 / HBN7 Oven Use and Care Manual

Cooking with the BOSCH Convection Oven

In a conventional oven, the heat source cycles on and off to maintain an average temperature in the oven cavity.
As the temperature gradually rises and falls, gentle air currents are produced within the oven. This natural
convection tends to be inefficient because the currents are irregular and slow. In the Bosch convection system,
the heat is “conveyed” by a fan that provides continuous circulation of the hot air.

The Bosch Genuine European Convection™ system provides state-of-the-art engineering and advanced design
to create the finest convection oven. In standard convection ovens, a fan simply circulates the hot air around the
food. The Bosch convection system is characterized by the combination of an additional heating element located
around the convection fan and the venting panel that distributes heated air in three dimensions: along the sides,
the top and the full depth of the oven cavity. This Genuine European Convection system aids in maintaining a
more even oven temperature throughout the oven cavity.

The circulating air aids in speeding up the baking process and cooks the food more evenly. By controlling the
movement of heated air, convection cooking produces evenly browned foods that are crispy on the outside yet
moist inside. Convection cooking works best for breads and pastries as well as meats and poultry. Air-leavened
foods like angel food cakes, soufflés and cream puffs rise higher than in a conventional oven. Meats stay juicy and
tender while the outside is flavorful and crisp.

By using Bosch Genuine European Convection, foods can be cooked at a lower temperature and cooking times
can be shorter.
25°F. Foods requiring a cooking time of less than 30 minutes should be checked slightly earlier than normal.
Items that typically cook for 45 minutes or more should take 15-25% less time. For best results, foods should be
cooked uncovered, in low-sided pans to take advantage of the forced air circulation. When using the Convection
Roast mode, the standard oven temperature does not need to be reduced.

When using the Convection Bake mode, the standard oven temperature should be lowered by

Advantages of Convection Cooking

• Even baking, browning and crisping are achieved.

• During roasting, juices and flavors are sealed in while the exterior is crisp.

• Yeast breads are lighter, more evenly textured, more golden and crustier.

• Air-leavened foods such as cream puffs, soufflés and meringues are higher and
lighter.

• Baking on multiple racks at the same time is possible with even results.

• Multiple-rack baking saves time.

• Prepare whole meals at once with no flavor transfer.

• Dehydrates herbs, fruits and vegetables.

• Requires no specialized bakeware.

• Saves time and energy.

• Convection broiling allows for extraordinary grilling with thicker cuts of food.

arrows represent the location of the heat source during
specific modes. The lower element is concealed under
the oven floor.

Bosch HBL7 / HBN7 Oven Use and Care Manual

CONVECTION ROAST

Convection Roast uses the top element, bottom
element and convection fan.

BAKE and WARMING

Baking is cooking with heated air. Both the upper and
lower element cycle to maintain the oven temperature.
In the Warming mode, the oven will use the lower
element to maintain a low temperature to keep food
at serving temperature.

BROIL

Broiling uses intense heat radiated from the upper
element.

CONVECTION BAKE and DEHYDRATE

Convection Bake cooks with heat from a third element
behind the back wall of the oven. The heat is circulated
throughout the oven by the convection fan.
Dehydrating is similar to convection cooking and holds
an optimum low temperature while circulating the
heated air to remove moisture slowly for food
preservation.

CONVECTION BROIL

Convection Broil combines the intense heat from the
upper element with the heat circulated by the
convection fan.

Oven Operations

Bosch HBL7 / HBN7 Oven Use and Care Manual

General Oven Tips

Preheating the Oven

• Preheat the oven when using the Bake, Convection
Bake and Convection Roast modes.

• Preheating for Convection Roast when using the
probe is not recommended. See Pages 20 through
22 for details and tips.

• Selecting a higher temperature does not shorten
the preheat time.

• Preheating is necessary for good results when baking
cakes, cookies, pastry and breads.

• Preheating will help to sear roasts and seal in meat
juices.

• Place oven racks in their proper position before
preheating.

• During preheat, the selected cooking temperature
can be displayed by touching TEMPERATURE.

• A beep will confirm that the oven is preheated and
the selected cooking temperature will be displayed.

• Fast Preheat Bake and Fast Preheat Convection Bake
can be used when time is crucial.

Operational Suggestions

• Use the cooking charts as a guide.

• Do not set pans on the opened oven door.

• Use the interior oven light to view the food through
the oven door window rather than opening the door
frequently.

Utensils

• Glass baking dishes absorb heat. Reduce oven
temperature 25°F when baking in glass.

• Use pans that give the desired browning. The type
of finish on the pan will help determine the amount
of browning that will occur.

• Shiny, smooth metal or light nonstick/anodized pans
reflect heat, resulting in lighter, more delicate
browning. Cakes and cookies require this type of
utensil.

• Dark, rough or dull pans will absorb heat resulting
in a browner, crisper crust. Use this type for pies.

• For brown, crisp crusts, use dark nonstick/anodized
or dark, dull metal utensils or glass bakeware.
Insulated baking pans may increase the length of
cooking time.

• Do not cook with the empty broiler pan in the oven,
as this could change cooking performance. Store
the broil pan outside of the oven.

High Altitude Baking

• When cooking at high altitude, recipes and cooking

time will vary from the standard. For accurate
information, write the Extension Service, Colorado
State University, Fort Collins, Colorado 80521.
There may be a charge for the bulletins.

Oven Condensation and Temperature

• It is normal for a certain amount of moisture to
evaporate from the food during any cooking
process. The amount depends on the moisture
content of the food. The moisture may condense
on any surface cooler than the inside of the oven,
such as the control panel.

• Your new Bosch oven has an electronic
temperature sensor that accurately maintains the
temperature selected. Your previous oven may have
had a mechanical thermostat that drifted gradually
over time to a higher temperature. It is normal
that you may need to adjust your favorite recipes
when cooking in a new oven.

Oven Racks

• The oven has rack guides at four levels as shown
in the illustration on Page 7.

• Rack positions are numbered from the bottom rack
guide (#1) to the top (#4).

• Check cooking charts for best rack positions to
use when cooking.

• Each level guide consists of paired supports formed
in the walls on each side of the oven cavity.

• Always be sure to position the oven racks before
turning on the oven. Make sure that the racks are
level once they are in position.

• To remove oven rack from the oven, pull rack
forward, lift rack up at front and then remove it.

• To replace an oven rack:

1. Place rear of rack between rack level guides.

2. While lifting front of rack, slide rack in all

the way while lowering the front. Please
refer to illustration on Page 7 if there is any
question as to which side is the front of the
rack.

• The racks are designed to stop when pulled
forward to their limit.

• CAUTION! Never use aluminum foil to cover
the oven racks or to line the oven. It can cause
damage to the oven liner if heat is trapped under
the foil.

120/240 vs. 120/208 Volt Connection

• Most oven installations will have a 120/240 voltage
connection.

• If your oven is installed with 120/208 voltage, the
preheat time may be slightly longer than with 120/
240 voltage.

• The Self-Clean mode may also require a longer
clean time, depending on the amount of soil.
