Double, double toil and trouble, fire burn and kettle bubble.
Stovetop kettles are simple vessels for heating water. But anyone who’s had a bad one knows how irritating they can be. Poor kettles are apt to whistle too faintly or painfully loudly, rattle and clank on the burner, and be too cumbersome to hoist—or, conversely, too tiny to make a full-size pot of tea. Their handles can get too hot, they can make a splashy mess when pouring, and they can send steam up to scorch your hand. They rust or dent and get grungy living on the stove, where they’re on display for all to see. Still, we had faith that there were good, functional, durable kettles out there—we just had to find them.
To do so, we bought six kettles, priced from $9.99 to $74.95 and in a variety of materials from stainless steel to enamel-coated steel to borosilicate glass, with capacities ranging from 0.84 to 3 quarts. We put every model through a gamut of tests, evaluating how easy it was to fill and lift, as well as how long it took to reach a boil. We boiled water in each kettle multiple times, at both its maximum and minimum capacities, and had a variety of testers pour out hot water into a single mug, trays of teacups, a 1.5-quart teapot, and a filter cone to make pour-over coffee, evaluating how difficult or easy it was to control the pouring. We also got each kettle dirty and banged it around before rating it on ease of cleaning and durability.
Our first discovery was that the practical capacity of some of the kettles was much smaller than advertised: When we filled them to their stated capacities, the water went right up to the brim, causing overflow at the boil. The worst offender held almost a quart less than advertised. Rule of thumb: Most kettles should be filled to just under the interior spout opening.
While the majority of the kettles were easy to fill, with wide openings and good interior visibility, a few were cramped and dark, making it difficult to judge when they were full. The worst had a black enamel interior; we had to pull out a flashlight, or even stick a finger in, just to be sure the water was below the spout. What’s more, this kettle’s opening had a low, fixed handle curving over it that made it hard to access.
Once boiling, the whistling kettles were a boon, but only if we could hear the whistle from the next room. One was so quiet that you had to guess if it was making noise from barely 3 feet away. We found two styles: whistles that you can disable and ones that you can’t. We preferred the two kettles that let you turn off the whistle if you want it to boil silently.
Most of our lineup boiled a full kettle of water in a reasonable time, roughly 8 to 11 minutes, but there was one outlier that was much slower due to its design. With a tiny base and stern instructions to keep the heat at low to medium, it took 18 to 20 minutes to boil a full pot—we’d be late for work if we waited for that. When pouring into cups, pots, or coffee-filter cones, some kettles were imprecise and harder to control, splashing and glugging, but the best were easy to pour precisely with nary a drop spilled. As for capacity, we wanted a kettle that was roomy but not too heavy. While it’s nice to be able to boil a large volume, the biggest kettle was heavy when empty and weighed upwards of 7½ pounds when full. Another, a gooseneck kettle, was lightweight and was testers’ favorite for precise pouring, but it ran out before our teapot was full. Our favorite model poured almost as smoothly as this small kettle and held almost as much as the biggest kettle but at a fraction of its weight.
To see how easy the kettles were to clean, we sprayed their exteriors with cooking oil and heated them to bake it on. Once they had cooled, we tried to scrub it all off. Kettles lost points for having nooks and crannies that trapped pockets of grease or for not being fully clean after being scrubbed with hot soapy water. Only one kettle was dishwasher-safe, so we ran it through three cycles to see if it sustained any damage (it did not). To simulate years of knocking around a busy kitchen, we rapped kettles sharply on their sides with a wooden spoon and dropped them repeatedly from 3 inches above the countertop and then checked for dents or damage. A few showed minor dings from being struck, but one kettle had actually acquired a bigger dent during routine use, before we began our abuse testing.
While a few manuals instructed us never to leave kettles damp inside, we think patting dry the interior of a stovetop kettle after every use is wildly impractical and expect more from our tools. We left the kettles damp, with their lids on, over the weeks of testing to see if any would rust. While we didn’t see any rust, two kettles developed a brownish residue on their insides that we could see when we wiped them out with a paper towel—ew. In a taste test of water boiled in these kettles, both passed with a majority of favorable opinions, but both also garnered a few comments about a slightly metallic, stale taste.
In the end we found three kettles we fully recommended, with one standout. The OXO Good Grips Classic Tea Kettle in Brushed Stainless Steel ($39.95) did the best job of overcoming many of the problems that plague stovetop kettles. Sturdy but lightweight for its size, it has a generous but not overwhelming capacity, a pleasantly grippy silicone handle, a curving spout that pours “remarkably smoothly,” a wide opening, a handle that folds down for easy filling and cleaning, a light interior that is readily visible, and a brushed exterior finish that resists fingerprints. Its broad base helped it boil quickly, and its loud whistle, which can be disabled if you choose to leave the spout open, lets you know when your water is ready. While we’d prefer a slightly less snappy hinge on the spout cover, we can live with this minor quibble. This is a practical and durable kettle that we believe will be useful for years to come.
We purchased six stovetop kettles designed for boiling water, priced from $9.99 to $74.95, and tested them for performance, ease of use, and cleanup/durability on gas and electric-coil stoves. We list the kettles’ practical capacities (maximum actual water fill) rather than the manufacturers’ stated capacities, which often refer to filling the kettle to the top rim. To measure boiling times, we filled each kettle to its maximum capacity with 62-degree water and timed how long it took to reach boiling on the same burner (both gas and electric). Results of all tests were averaged to reach final scores. All kettles were purchased online and appear below in order of preference.
Performance: We preferred kettles that boiled reasonably quickly, signaled clearly when they were done, poured in a controlled and accurate way, and had sufficient capacity without being too heavy to handle.
Ease of Use: Kettles that were easy to fill and pour from; felt comfortable, safe, and secure to use; and kept our hands away from hot water, steam, and hot surfaces received higher marks. We preferred kettles with light-colored interiors.
Cleanup/Durability: We preferred kettles that were easy to clean, that had few nooks and crannies, and that could be scrubbed without lasting damage. Kettles that endured everyday abuse during testing, as well as being knocked with a wooden spoon and repeatedly dropped from 3 inches above the countertop without damage, rated highest. Kettles that resisted brown, slimy buildup were preferred.
Lightweight and easy to fill with its wide opening, good interior visibility, and handle that folds out of the way, this kettle was pleasant to use and has a generous capacity. Its whistle is assertive, its grippy handle is comfortable, and its spout has a gentle curve that lends itself to smooth pouring. It survived abuse tests with only the faintest dents, and the brushed-steel surface was easy to clean. A quibble: The lever on the whistling spout cover is stiff and snappy, and the pointy hinge underneath the lever sometimes poked our fingers when closing the spout. Also, it is not induction-compatible.
Pretty but pricey, this kettle is easy to lift even when full, and its wide opening and fold-down handle make it simple to fill and clean, though its dark enameled interior means visibility is slightly challenging. Its whistle was nicely audible, and its pouring felt secure, predictable, and controlled. It didn’t dent when whacked or dropped, but after leaving it damp inside throughout testing, we wiped its interior with a paper towel to find traces of brownish residue.
Petite and lightweight, this is a terrific kettle for small households, but we had to boil and pour it out twice to fill a full-size teapot. Its surprisingly comfortable, well-balanced handle and long, skinny spout made for surgically precise control, especially with pour-over coffee; this is the pot of choice for many baristas. Filling is easy since its handle doesn’t arch over the opening, which is wide enough to get your hand inside to scrub. A few things to note: It lacks a whistle, and occasionally the spout (which is set at the base of the kettle rather than higher up as on other kettles) sent out tiny spurts of water when boiling.
This handsome kettle was the biggest we tested, but it’s only for the strong: Extremely heavy when full, it also requires squeezing a tight, spring-loaded lever to keep the spout open, which was tiring. Pouring control was entirely dependent on arm strength. With its piercingly loud whistle, you’ll never miss the boil. A wide bottom made of five layers of steel, aluminum, and iron retains heat but slows down boiling: A full kettle took more than 11 minutes. A midsize dent appeared during routine handling, and small dents showed after abuse tests.
This tiny-looking but surprisingly capacious kettle is hard to fill accurately, since its interior is pitch black and its low, fixed handle leaves little space for the faucet. Its whistle is good and loud. While it’s comfortable to lift, even while full, it drips and sloshes a little while pouring. After we intentionally left the kettle wet between tests, we found brown residue when wiping the inside with a paper towel, a possible sign of rust; some tasters complained that water boiled in it tasted stale.
While it’s nice to see the water boiling through the clear glass, several flaws plague this old-school kettle: It claims to hold 12 cups but actually holds only 6, and it has no maximum fill line; it also comes with a laundry list of warnings about handling to prevent shattering (including never placing the hot kettle on a cold surface, never bumping the kettle, never brewing tea in it, and heating it on low or medium heat only), making us jumpy every time we picked it up or set it down. It boiled painfully slowly, and its whistle was far too soft for anyone in danger of boiling a kettle dry. You must remove the lid to pour, and the slightly uncomfortable handle feels off-balance until you’re pouring.
