We made beef stew in seven models from Instant Pot, Ninja, Crock-Pot, and more. Some were harder to clean, and one spat water and steam.

It’s officially soup (and stew and chicken and dumplings) season! As much as we wish we could drop everything and spend hours whipping up delicious seasonal meals, our daily duties don’t always allow it. If you’re crunched for time but still need to get food on the table each night (and prefer it to taste good), a slow cooker is your BFF cooking apprentice.

How to Use a Slow Cooker

This must-have device lets you toss ingredients in, set it to high or low, and let it do all the work in the background so a comforting meal is ready when you want it. In case you aren’t sure which slow cooker temperature to use for your meal, the “low” setting ranges from 164-182°F (peaking at 205°F after four hours), and the “high” setting tops out at around 205°F after four hours (these temperatures vary by model).

It’s important not to overcrowd your ingredients when slow cooking so that everything can cook evenly; for the best results, fill it between one-half and two-thirds full. And remember: the warm setting is convenient, but it’s not a substitute for low- or high-cooking settings. Your already-cooked food can remain warm in it, but the warm setting can’t cook ingredients.

A quality slow cooker is one that’s easy to program, carry, and clean. It should have a stable base, sufficient capacity for you and your family, and intuitive controls that do exactly what they say. 

CR tested seven popular slow cookers by brands such as Crock-Pot, Hamilton Beach, Ninja, Cuisinart, and more. Their prices ranged from $45 to $300, and we chose slow cookers with a capacity between 6 and 8.5 quarts. Then we set to work making batch after batch of beef stew and testing each device on its low and high settings, as well as its “keep warm” function. We found differences in how easy they are to operate and even how well they cooked our ingredients. 

Sneak peek: All of our slow cookers did an outstanding job of cooking meat and veggies to perfection, but the ones with intuitive interfaces and helpful features won us over. We also paid close attention to which were easy to clean or made our arms tired from all that scrubbing. 

These are the four slow cookers you need in your busy life.
