Oster Electric Roaster OvenThe versatile Oster electric roaster oven is a countertop electrical kitchen appliance that can bake, roast, steam, slow cook and keep food warm.

The wide metal roaster comes with a large removable pan, heating element either at the side or bottom, a lid and usually a roasting rack is included.

Oster 20-Quart Roaster Oven with Defrost and Self-Basting Lid

The Oster 22 quart roasting oven comes with a self basting lid.

The roaster oven with self basting lid speeds up cooking time, thus saving time, energy and heat.

You do not have to baste your food manually.

The self basting lid is designed in such a way that it recirculates moisture on its own.

There are grooves on the lid that catch the water condensation. The droplets drip back onto the cooking food.

Without the basting lid and its grooves, water moisture drips down the sides of the pan only and not onto your food.

This is great for busy moms who do not have time running back and forth to check on their turkey etc.

Then place the empty serving dishes securely onto the frame.

Cover back the lid and preheat water until hot (Set to 350°F for 30 minutes).

Lift up the lid and add your hot cooked food into the 3 serving dishes.

You have to use all 3 serving dishes even if only 1 is filled with food.
