There are a few different types of outdoor turkey fryers. Some are electric, some are propane. Some that are traditional deep fat turkey fryers, and some that are oil free or oil-less turkey fryers.
I wanted to touch upon the later two as they are made by very respectable companies that primarily make outdoor cooking gear. They are safe, easy and cook great. The thing is, is that they really are not deep fryers. They technically roast the bird using radiant heat or infrared heat.
A few of the upsides here are less mess, easier clean up, less of a fire hazard, other cooking options.
Obviously, you have a virtually splatter free cooking unit, as you have no oil to spit, pop, or boil over. This makes clean up much easier as you do not have to wait for indoor greaseless turkey fryer. You don’t have oil to filter and store. You still need to wait for the unit to cool down before clean up and storage, but this will take considerably less time than a unit full of hot oil. Some of the pieces of these units are dish washer safe, therefore also saving time. Certain parts must be hand cleaned and should never be submerged in water though.
These units are safer as there is no hot oil that can come in contact with open flame, which could pose a potential fire hazard. Safety precautions should still be taken though. No pets or kids, of any age, running around the unit at all. Remember that you still have either an electric cord or a propane tank hooked to a hot container that is full of hot food. The sides of the unit will be hot. Make sure that you have appropriate protective gloves and your handling equipment on hand. Even though there is less of a potential for fire, you should still keep a constant eye on any outdoor cooking equipment.
Using no oil is a healthier option compared to deep fried foods. Less calories and no oil, but still having crispy yet juicy turkey is a definite up point.
