About the Swiss Diamond 11.8-inch Nonstick Wok

This wok is the newest addition to Swiss Diamond’s wok collection, which already includes 11-inch, 12.5-inch and 14-inch versions. This version comes with a tempered glass lid and a metal tempura rack. The wok is made of pressure cast aluminum and is coated with Swiss Diamond’s proprietary PFOA-free nonstick coating.

The company claims that the diamond crystals used in the nonstick coating help give strength to the coating, and a layer of diamond crystals beneath the nonstick coating also ensure that even if the coating is damaged, food will never come in contact with aluminum.

The handle is attached via an exterior bolster to avoid interior rivets that could trap food. A helper handle is molded into the body of the pan. The glass lid has a stay-cool knob handle and an adjustable steam vent.

The Swiss Diamond Nonstick Wok to the Test

This wok is a perfect size for stir-fry: not too big, not too small. The coating is slick enough so that little or even no oil is needed. Because of the thickness of the pan, it takes a few moments to heat up, but once it does, it maintains the heat well and distributes heat evenly, even at the high temperatures needed for wok cooking. I liked that the pan is heat safe up to 500˚F.

I can't think of any reason why you'd need a wok in the oven, but on the rare occasion that this need might arise, there's no need to worry about damage to the pan or the handle. 

The perfectly flat base means that the wok is ideal for glass stoves, and on gas stoves, it seemed to get just as hot on the burner rack as a traditional carbon steel wok does using a wok ring.


The slope of the pan was just angled enough for me to easily keep food moving around with a pair of tongs (silicone-coated, of course, so I wouldn’t damage the nonstick coating!). And the included metal rack came in handy to rest finished ingredients while the others were still cooking.

Woks are also known as a good vessel for frying foods, and the Swiss Diamond wok was no exception. It has a capacity of nearly 5 quarts (For frying I used about 2 quarts of oil so I'd have plenty of room to add ingredients)  and is wide enough to fry quite a few pieces at once. The metal rack also was useful for frying tempura; the cooked pieces can drain and stay warm while the next batch is being fried. The frying function makes the wok far more useful than just cooking Asian foods; its size and shape would be great for frying chicken or doughnuts, and the thick cast aluminum body helps keep the temperature of the hot oil steady.

The Swiss Diamond nonstick wok was also easy to clean. Technically the wok is dishwasher safe, but the company recommends that it be hand washed, and I agree. It's so easy to wash that this is not an issue, anyway. The nonstick coating does indeed keep food from burning onto the pan, and the handle is designed so that there are no interior rivets that must be scrubbed around and which could trap food and build bacteria.


Note: If you have an induction cooktop, you'll need to buy from Swiss Diamond's induction-compatible line, which is a little more expensive.
