Where will you store your deep fryer? Deep fryers come in all sizes; if you use yours frequently, you may want to leave it on a countertop, but you need to consider how much space it will take up. If you use your deep fryer less often, you'll need to consider where to store it when it's not in use.
Do you enjoy different cooking methods? A few deep fryers have features that make them useful for multiple purposes. The T-fal ActiFry (Est. $180), for instance, can make risotto and a variety of other foods, while other fryers double as steamers or boilers. If you like to experiment, or just prefer multi-use appliances, choose a deep fryer with a little versatility.
Are you cutting back on fats? If you're on a low-fat diet for whatever reason, oil-less deep fryers cook food with no oil or very little oil, so the resulting cooked food will have less fat than a comparable serving cooked in oil. However, according to professional tests, foods that are properly cooked in standard deep fryers absorb very little oil anyway.
Will you reuse the oil? Whether you want to recycle or just save money, you'll probably want to use the same oil at least a few times. Opt for a deep fryer with built-in filtration or a drainage system that can be easily configured with your own filtration method, so you can store the oil for later use without too much hassle.
Home deep fryers are perfectly safe when used properly; however, they have the potential to do a lot of harm as well. Deep fryers are estimated to result in more than $28 million in property damage each year. You must be especially careful when using turkey fryers. Butterball has an excellent, very detailed guide to properly deep frying a turkey safely whether indoors or out. We urge you to study it before you attempt to deep fry your first turkey -- and then review it as a refresher each time you use the fryer for a turkey.
As for other types of deep fryers, follow all manufacturer's instructions to the letter, don't overfill your fryer, and always keep children away from these appliances. In addition, we recommend always placing the deep fryer on something like heavy cardboard or a grill mat just in case of spills, regardless of whether you use it indoors or out.
