A slow cooker promises to be a little fantasy grandmother who sits in the kitchen all day cooking for you, but use the wrong cooker and that dream could fizzle. A cooker might run hotter than expected, drying out the food or turning it mushy, or slower than you want, so dinner isn’t ready when you are. Then there can be issues with hot spots, which make food cook unevenly. And what if operating your machine is so confusing that you have to pore over the manual each time you use it?
For the ideal machine that would deliver a properly cooked meal and be absolutely simple and intuitive to use, we went shopping. Previous experience taught us that glass lids were a must, as they allow you to see progress without losing heat. So were oval-shaped crocks, as these can accommodate large roasts and offer more versatility than round crocks. We also wanted a generous 6- to 7-quart capacity. With these criteria in mind, we rounded up eight models priced from $39.99 to $148.71.
We tested these eight slow cookers, preparing a variety of recipes using both low and high temperature settings and varied cooking times. We used temperature probes to map heating patterns, and a panel of testers evaluated how easy the cookers were to use and clean. We also dismantled a set of the cookers to understand the placement and type of heating elements they contained. What were our favorites of the bunch?
The KitchenAid 6-Quart Slow Cooker With Solid Glass Lid ($99.99), our former winner, handled every recipe with perfect results, albeit a bit slowly. Its thick stoneware crock, insulated housing, built-in thermal sensor, and crystal-clear controls put a well-thought-out design at your service—and at a moderate price. The Cuisinart 6-Quart 3-in-1 Cook Central ($148.71) is also a solid choice. It offers the advantages of a light, unbreakable metal crock with stay-cool plastic handles, as well as a brown-and-sear function that lets you skip using a separate skillet before slow-cooking in recipes that call for it.
