The Breville BDF500XL Smart Fryer 4 Quart Deep Fryer is the first deep fryer with technology that adjusts time and temperature to suit what you're cooking with 7 preset functions.

Simply select what you are cooking and this smart appliance will deliver the right temperature at just the right time. The Smart Fryer also includes a twice-fried function for restaurant quality French Fries and makes adjustments for fresh or frozen ingredients. And the custom setting allows you to program your favorite dish.
