A combination microwave convection oven uses either convection heat, microwave radiation or a combination of both to cook or reheat food and drinks. This combination allows for the speedy convenience of a microwave oven and the browning and roasting features of a convection oven to be combined in one unit. These time-saving appliances are available as both countertop or built-in versions and usually contain a microwave-safe metal rack that may be left in the unit at all times.
Place the food or drink in the oven. If using the microwave setting, be sure to use a microwave-safe container. If using the combination setting, use heat-resistant glass. If using the convection setting, you may use a metal roasting pan or other metallic container. Close the oven door.
Choose a cook setting on the device. Most microwave convection ovens allow you to specify whether you want to use the convection heat or the microwave or a mixture of both. A setting labelled "Low Mix" or "Bake" uses 10% of the microwave energy along with the temperature you set for the convection setting. A setting labelled "High Mix" or "Roast" will use 30% of the microwave energy throughout the convection cooking process.
Preheat the oven if using the combination or convection cooking settings. Many microwave convection ovens have a thermal gauge that tells you the temperature inside of the oven. Some ovens sound a buzzer or alarm when the thermal gauge matches the temperature set for the convection cooking setting.
Locate the timer setting or the timer knob and set the oven for the amount of desired cooking time. For a digital display, you typically need to press the timer button and then enter the amount of cooking time in minutes and seconds using the number pad. Older ovens have an analogue dial that needs to be set. Additionally, some models can be programmed to perform timed cooking cycles, such as cooking with the microwave to defrost frozen food and then cooking with the convection oven or a mix to thoroughly cook the food. Consult the user manual of your device for these advanced settings.
Press the "Start" or "Cook" button to begin the cooking process.
Open the oven door and remove food after cooking, using a potholder or heat-resistant glove. Check for desired temperature and continue cooking if necessary. Set the timer and temperature setting to "0" or turn off each element by pressing a "Clear" or "Off" button.
Only use the metal rack that came with the microwave convection oven. Never allow any food or part of a cooking container to touch the inside walls of the oven.
