Choosing the Best Slow Cooker

Home-cooked meals are often the first casualty of a hectic schedule. But if you're not willing to sacrifice everyday gourmet, a slow cooker can take the frenzy out of preparing dinner. Perfect for soups, stews, and tough cuts of meat, slow cookers are designed to simmer food at a low temperature for an extended period of time.

CR bought and tested over a dozen slow cookers from All-Clad, Black+Decker, Calphalon, Crock-Pot, Crux, Cuisinart, Elite, Hamilton Beach, KitchenAid, and Pioneer Woman.  

Prices for the programmable slow cookers range from $50 to $170, but the cost of the cooker didn't predict performance. The manual slow cookers we tested sell for $30 to $40.

Lab Tested for Your Kitchen

Past tests found that any slow cooker we tested could turn out tender, delicious garlic honey chicken. The real challenge? Beef stew with potatoes and carrots, which is why in our latest tests we cooked pots and pots of beef stew with on high heat for 5 hours, and then cooked this same dish on low heat for 8 hours. Staffers sampled the results, weighing in with their opinions on taste and tenderness.

We also evaluated convenience, such as the clarity of the controls, and how easy it is to program the slow cooker. We noted whether models have a lid that locks, a feature that prevents food from spilling when you want to transport it to potlucks and parties.

Slow Cooker Types

Basic manual slow cookers have an on/off button and not much more. If you spend more, you can get a programmable slow cooker that lets you choose the cooking time, and more.

Programmable Slow Cooker

Electronic controls and a digital timer let you choose cooking time. Some let you program the slow cooker for up to 24 hours in 30-minute increments and the digital display shows remaining cooking time. All of the tested models automatically switch to a keep-warm setting when set time is up, and can keep food warm for hours. Some also have manual mode.

Manual Slow Cooker

All you have to do is just turn the control to the desired setting—low, medium, or high. Manual models do not have a timer so you'll have to monitor the cooking, especially for smaller quantities of more delicate foods, and you'll have to turn off the slow cooker. Some have a keep-warm setting, but you'll have to switch to this mode.

Features to Consider

Sturdy handles are a must, but slow cookers also offer features you might find useful, like roasting racks to let you roast meat and poultry or steam vegetables, wrap-around cord storage, and insulated carrying bags.

Pots
Most slow cookers we've tested have a ceramic pot that's oval, a shape that accommodates roasts or other large cuts of meat better than a round slow cooker can. 

Lids
A glass or clear plastic lid lets you watch your progress without removing the lid and releasing heat. Some slow cookers have a hinged lid—handy when serving up food—though none in our current ratings do. A lid that locks helps keep food from spilling while in transport to potlucks and parties, and some cookers have a handle on the lid that makes the slow cooker easier to carry.

Capacity
Capacities can range from 1.5 to 8.5 quarts. But some owner's manuals say to fill the pot 1/2 to 3/4 full to avoid under- and over-cooking and to prevent spillovers. Most of the slow cookers in our ratings are 6-to-7 quart models, a popular size. Even slow cookers with similar capacities can vary in size. The bulky ones are more difficult to store and transport, and of course they eat up more counter space. Note that the tested models weigh between 7 and 17 pounds.

Temperature Probes
Slow cookers aren't loaded with new features, but temperature probes pop up on some. Insert the probe into a large cut of meat, choose the temperature you want the meat to reach, and when it does, the slow cooker will switch to the keep-warm setting. The owner's manual for the Hamilton Beach Temp Tracker we tested includes tips on using the temperature probe and hold-temp mode to cook using the sous vide method.

Ease of Cleaning
An easy-to-clean pot and lid that can go into the dishwasher is handy. And keep in mind that touchpad controls are easier to clean than knobs and buttons.

Keep a Lid on It: Slow Cooker Safety Tips

As easy as they are to use, slow cookers can pose a health risk if the food is not cooked properly. The USDA recommends the following.

• Keep perishable foods refrigerated until prep time. If you cut meat and vegetables in advance, store them separately in the refrigerator.
• Always thaw meat or poultry before putting it into a slow cooker.
• Check the owner's manual for suggested amounts. Make sure you add the right amount of liquid.
• If the power goes out during the cooking process and you are not at home, discard the food even if it looks done. If you are at home, finish cooking it by some other means such as on a gas grill or at a neighbor's.
•Transfer leftovers into a shallow container and store in the refrigerator.
• Don't reheat leftovers in a slow cooker. Instead, use a stove or microwave and heat to an internal temperature of 165° F. After that, you can return the food to the preheated slow cooker for transport or serving.
