Without a doubt, this has to be the most common complaint in regards to roaster ovens. Several users have reported experiences with roaster ovens that left them displeased because their turkey did not brown on the outside. Because of this, it is a misconception that roaster ovens lack the ability to brown a turkey in the same manner a conventional oven can. All you need to do is heat it at the correct temperature and baste it the same way you would a regular turkey.
The temperature aspect can often be the trickiest part as roaster ovens heat better than a traditional oven due to their compact size. Because of this, the timing and temperature may have to be altered from your original recipe. If using the same temperature, check your turkey before you usually would as it will probably cook faster.
