Rice Cookers

Published June 2021

How we tested

The best rice cookers consistently prepare multiple varieties of rice well with the push of a button. We found two models that make exceptional rice and are also easy to use and clean. The Zojirushi 5.5-Cup Neuro Fuzzy Rice Cooker & Warmer is our top performer, followed closely by the Toshiba 6-Cup Rice Cooker with Fuzzy Logic. They both have clearly labeled measurement lines inside their cooking bowls and audible alerts that signal when they have finished cooking and switched to their keep-warm settings. And since both machines have removable inner lids and slick nonstick-coated cooking bowls, they are a breeze to clean. The Zojirushi came out on top due to the convenient plastic handles on either side of its cooking bowl, which protected our hands from the heat when scooping cooked rice. 

What You Need to Know

You can make rice on the stovetop (or in the oven), but there are advantages to using a rice cooker: The process is mostly hands-off and yields consistent results from batch to batch. Plus, a rice cooker can keep cooked rice warm for hours without sacrificing quality. Rice cookers were developed for home use in Japan in the 1950s. Prior to that, Japanese home cooks used a centuries-old technique of preparing rice in either a cast-iron hagama or an earthenware donabe on a kamado (wood-burning stove). The electric rice cooker automated and simplified this time- and labor-intensive process first in Japan and then around the world.

So how do rice cookers work? An internal heating plate located beneath the cooking bowl in most models, or surrounding the cooking bowl in others, heats the water. The rice absorbs the water as it cooks, and steam escapes through a vent in the top of the machine. A sensor inside the machine registers when the temperature rises above 212 degrees—the highest temperature water can reach when not heated under pressure, indicating to the machine that all the liquid has been absorbed or evaporated. Every model in our lineup automatically switches to a “keep warm” setting when the rice is done cooking.

We’re happy to report that most of these machines made acceptable rice the very first time we used them, though some machines initially produced wetter rice than others. Rice cookers are designed to take the guesswork out of making rice, but there was a learning curve with certain machines. With some small adjustments to the ratio of rice to water, we were able to cook rice to our preferences in most of the machines. What differentiated these machines more was their ease of use.

Some models we tested were very simple to operate: After rinsing the rice, we measured it and added it along with the corresponding amount of water to the cooking bowl and then just flipped a switch to start the cooking process. Other models had several settings for different types of rice and styles of cooked rice dishes. Some of these more advanced models employ "fuzzy logic" technology that adjusts the time and temperature as the rice cooks in order to get the best results.

Some of the rice cookers in our lineup include a soaking phase at the beginning of the cooking process and a steaming step at the end of it to purportedly improve the texture of the cooked rice. To find out which models actually performed these functions and how long they took, we monitored the temperature inside each rice cooker throughout their cooking cycles. While our tests didn't produce any definitive data confirming the existence of these stages, we did discover that those with lower temperatures at the start of cooking and longer cooking periods produced the best rice. The fastest cookers made large batches of long-grain white rice in about 30 minutes, while the longest cookers took about 65 minutes. Here, speed wasn’t an advantage; we found the quality of the rice to be superior in the machines with longer cooking cycles.

What to Look For

  • Longer, Slower Cooking Times: Rice cookers with longer cooking cycles produced better results than those with shorter cycles. The machines that kept their water temperatures low during the first few minutes of cooking (an indication of an initial soaking step) produced rice that was evenly cooked through (no blown-out grains); the grains also retained a nice chewy texture. 
  • Clearly Labeled Measuring Lines: It’s crucial to use the right ratio of water to rice to achieve well-cooked rice, so we liked the models that had clearly marked water measurement lines on their cooking bowls. Since all the bowls of the models we tested were dark-colored, those with white measurement lines were the easiest to read.
  • Intuitive and Clearly Labeled Displays: Two of the simplest rice cookers had just an “on” switch, but even the machines with several more cooking options were easy to use if the operating displays were clearly labeled. 
  • Digital Countdown Timers and Audible Alerts: We liked models with timers. Some began as soon as we pressed "start,” while others started when there was 10 to 15 minutes left in their cooking cycles. We also liked machines with audible alerts that let us know when our rice was done.
  • Removable Inner Lid: As the rice cooked, starch collected on the undersides of the machines’ lids. We preferred models with removable lid inserts or with lids that could be removed entirely because they were easier to wash and dry thoroughly. 

Nice to Have

  • Handles: Plastic handles on either side of a cooking bowl allowed us to easily remove it from the machine, even when the bowl was hot. Handles also made portioning rice easier because we could hold the bowl with one hand and scoop with the other. 

What to Avoid

  • Hard-to-Read Measurement Lines: Cooking bowls with stamped or raised measurement lines were difficult to decipher. We had to move our heads around to catch a glimpse of these lines when the lighting was right.
  • Machines That Cook Hot and Fast: Machines that quickly heated the water and cooked the rice for shorter periods of time produced rice that consistently ranked lower than rice made in machines that cooked it more slowly. This was especially true in our brown rice tests.
  • Hard-to-Clean Machines: One machine lacked a detachable lid insert, and it was difficult to wash and rinse it while it was still attached to the body of the rice cooker. With a few models, starchy water escaped through the steam vent cap or hole in the rice cooker's lid, leaving a bit more for us to clean up. We noticed starchy water leaking from the side of another machine.

Other Considerations

  • Trial and Error with Ratios Can Be Expected in Many Models: Some rice cookers provide standard water-to-rice ratios for all types of rice, while others require more water for certain varieties of rice. With most machines, the ratios for long-grain white rice to water worked perfectly the first time we tried them. But when we used the recommended ratios for medium-grain brown rice, the resulting rice was often too wet. We preferred using the amount of water required for making long-grain white rice when making brown rice.
  • Pro Tip: After making a batch of rice, take note of whether the water-to-rice ratio produced the texture you prefer. Some people prefer softer rice (which requires more water), while others prefer firmer rice (which requires less water). Tweak the amount of water and experiment with the available settings as you get to know both your rice cooker and the different types of rice.

FAQs: How do you use a rice cooker?

  • Measure the rice with the provided measuring scoop (the scoops of all the models in our lineup held approximately ¾ cup). (If you’re rinsing your rice, place it in a fine-mesh strainer and hold it under running water until the water running through the rice is almost clear, about 1 minute, agitating the rice with your hand every so often.) 
  • Transfer the rice to the cooking bowl. 
  • Fill the cooking bowl to the corresponding water line. (For example, add enough water to reach the “2” line for two scoops of rice.)
  • Switch on the machine. (On machines with multiple settings, select the correct cooking method or style of rice or grain.) 
  • When your rice is done cooking, use the provided paddle to gently fluff the rice from the bottom upward, allowing excess moisture to escape without damaging the grains. Fluffing the rice also helps prevent clumping.

Methodology

  • Cook a small batch of long-grain white rice
  • Cook a large batch of long-grain white rice
  • Cook a half-capacity batch of short-grain white rice
  • Keep short-grain white rice rice warm for 2 hours
  • Cook 2 cups of medium-grain brown rice
  • Cook a half-capacity batch of long-grain white rice with a data logger inside to track the temperature of the rice and water during cooking
  • Top three models only: Test the quick-cooking setting with long-grain white rice and test the “keep warm” setting for 12 hours with medium-grain brown rice
  • Wash inner lids or glass lids after every test
  • Wash all cooking bowls with soap and water after every test

Rating Criteria

Performance: We evaluated how well each rice cooker cooked short-grain brown rice and long- and short-grain white rice.

Ease of Use: We rated how easy it was to use the rice cooker, including how well we could read the measurement lines and how clearly labeled and intuitive the display was.

Cleanup: We evaluated how easy it was to clean the rice cookers, including the inner lid, cooking bowl, and outside of the machine (where applicable).

Design Trifecta 360 Knife Block

Admittedly expensive, this handsome block certainly seemed to live up to its billing as “the last knife block you ever have to buy.” The heaviest model in our testing, this block was ultrastable, and its durable bamboo exterior was a breeze to clean. Well-placed medium-strength magnets made it easy to attach all our knives, and a rotating base gave us quick access to them. One tiny quibble: The blade of our 12-inch slicing knife stuck out a little.

Schmidt Brothers Downtown Block

This roomy block completely sheathed our entire winning knife set using just one of its two sides—and quite securely, thanks to long, medium-strength magnet bars. Heavy, with a grippy base, this block was very stable. An acrylic guard made this model extra-safe but also made it a little trickier to insert knives and to clean; the wood block itself showed some minor cosmetic scratching during use.

$141.90*

Schmidt Brothers Midtown Block

This smaller version of the Downtown Block secured all our knives nicely, though the blade of the slicing knife stuck out a bit. With a base lined with grippy material, this block was very stable. An acrylic guard afforded extra protection against contact with blades but made it a little harder to insert knives and to clean; the wood itself got a little scratched during use.

Swissmar Bamboo Magnetic Knife Block

This small, scratch-resistant model had a stable, rubber-lined base and could hold all our knives, though the blade of the 12-inch slicing knife stuck out a bit. But inch-long gaps between its small magnets made coverage uneven and forced us to find the magnetic hot spots in order to secure the knives. Its acrylic guard made it safer to use but harder to insert knives and to clean.

Messermeister Walnut Magnet Block

This handsome block was done in by its shape—a tippy, top-heavy quarter-circle that wasn’t tall or broad enough to keep the blades of three knives from poking out. It lacked a nonslip base, and its extra-strong magnets made it unnerving to attach or remove our heavy cleaver. Finally, it got a bit scratched after extensive use.

$129.95*

Epicurean Standing Knife Rack 12"

This magnetic block sheathed all our knives completely, though with a bit of crowding. But it was hard to insert each knife without hitting the block’s decorative slats on way down, and because the block was light and narrow, it wobbled when bumped. Worse, we couldn’t take it apart, so splatters that hit the interior were there to stay. Additionally, the outside stained easily, and when we wiped it down, the unit smelled like wet dog.

Kapoosh Rondelle Knife Block

This model stabilized knives with a mass of stiff, spaghetti-like bristles that shed and nicked easily after extensive use, covering our knives with plastic debris. While all our knives fit securely, several of the blades stuck out, making this unit feel less safe overall. Finally, though the bristles could be removed and cleaned in the dishwasher, their nooks and crannies made this block hard to wash by hand.

Kuhn Rikon Vision Knife Block, Clear

This plastic block required us to aim each knife into the folds of an accordion-pleated insert that was removable for easy cleaning but got nicked easily with repeated use. Because we could only insert the knives vertically, longer knife blades stuck out; a cleaver was too wide to fit. The lightest model in our lineup, this block was dangerously top-heavy when loaded with knives.
