Kenji's Updated Guide to Buying, Seasoning, and Caring for a Wok (Patreon)

This wok care guide is a living document. If you have more questions about woks, make sure to add them to the comments and I'll add answers where appropriate.

A good wok is one of the most versatile pieces of cookware you can own. There's a reason I wrote a whole book on the tool.

Yes, it’s the best tool for stir-frying, but it’s also a deep fryer with built-in splash control, a steamer, a blanching pot, a braiser, a sauce reducer, and, in a pinch, even a smoker. The sloped sides create temperature zones, convection patterns, and a food-tossability (that's a technical term) that simply don’t exist in Western-style flat skillets or sauté pans.

But like any tool, a wok only performs as well as its material and shape allow. The good news is that you don't need to spend an arm and a leg for one, and once you have the right one, taking care of it is straightforward—far less ritualistic than internet lore might suggest.

What follows is a practical guide to choosing a wok, understanding how it works, seasoning it properly, and maintaining it—whether you’re using a traditional carbon steel model or the Super Nitrided version I created with Our Place

My quick and dirty recommendations? Here you go:

Buy a 14-inch, flat-bottomed, 14- to 16-gauge (about 1.5 to 2mm thick) carbon steel wok with a long handle and a helper handle.

Skip stainless, cast iron, and nonstick. Carbon steel is the best material for stir-frying.

Scrub off and factory oil/coating before the first use, heat it well, wipe on a thin layer of oil, and start cooking.*

Clean it immediately after each use: rinse, dry thoroughly (heat-dry on the stove), and wipe on the thinnest possible layer of oil with a paper towel.*

Don’t panic about color changes, uneven patina, or the occasional sticky day.

*If you have my Super-Nitrided wok, there is no need to scrub before the first cook, and you can be a little more relaxed about how quickly you wash it after use.

If you want the “why” behind all of this, keep reading.

Buying a Wok

Q: How is a wok different from a skillet?

A: A wok isn’t just a curved skillet—it’s evolved over thousands of years to manage heat and movement in a way that optimizes the rapid evaporation of moisture from the food you are cooking in it.

While a Western skillet is designed to heat relatively evenly across a flat surface for tasks like searing meat or sweating vegetables. A wok is designed to create gradients. The center sits directly over the burner and gets screaming hot. The sides slope upward into progressively cooler territory. As food is added to the wok and tossed, this super-heated center allows surface moisture to evaporate quickly, while the wide, sloped sides allow food to be tossed high into the air, further encouraging evaporation and quick, even cooking.

The result is vegetables that are bright and crunchy and meats that cook rapidly and get evenly coated in sauces and seasonings.

Q: What material should my wok be made from?

A: For most home cooks, the answer is carbon steel.

You’ll see woks made from stainless steel, cast iron, carbon steel, and nonstick-coated metals. Each has tradeoffs, but only one consistently supports proper wok cooking. Here's what's up:

Stainless Steel is heavy and slow to respond to heat changes. Food sticks more than it should. Stir-frying is about control and motion, and stainless resists fast temperature adjustments and is too heavy for most cooks to toss efficiently with. Clad steel with an aluminum core (such as All-Clad) is even worse for wok cooking. Clad construction is designed to distribute heat evenly over a pan's surface. With a wok, you want the exact opposite.

Cast Iron is a little better. It has low thermal conductivity which means it can develop heat zones better than clad steel. It also has better surface slickness once seasoned. But thin cast iron can crack and thick cast iron is very heavy. Tossing food is fundamental to wok cooking. If the pan feels like a kettlebell, you’ll fight it instead of cook with it.

Coated Nonstick Woks are the worst choice. Nonstick coatings can’t tolerate the high heat proper stir-frying requires. The constant spatula and ladle use that wok cooking requires will also rapidly scratch and chip coated nonstick. Avoid traditional nonstick (Teflon-style) and silicone-based (ceramic nonstick) coatings for wok cooking.

That leaves us with carbon steel. This is the sweet spot.

It heats quickly, cools quickly, responds rapidly to burner changes, maintains distinct heat zones, develops a naturally slick surface over time, and can be constructed thin enough to stay relatively lightweight without the risk of cracking, the way cast iron can.

Look for something around 16- to 14-gauge (about 1.5 to 2mm thick). Thick enough not to flex. Thin enough to maneuver easily.

Q: What about your Super Nitrided wok?

A: My Super Nitrided wok is carbon steel at its core and behaves exactly the same in terms of cooking. The nitriding treatment uses high pressure and heat to impregnate the surface layers of the steel with nitrogen. This improves corrosion resistance, improves slickness, and hardens the material to make it even tougher and longer-lasting. Because the nitriding treatment is integral to the material, it is not a coating. It tolerates high heat, produces wok hei (more on that later), and can safely be used with metal utensils.

While other nitrided woks exist on the market, Our Place's unique super nitriding process creates a nitride layer that is about twice as thick as traditional nitriding, making it even tougher and slicker.

Do you need my new wok? Absolutely not. I worked with the same raw carbon steel wok for 20 years before upgrading to this new technology. That said, for anyone who wants to remove some of the maintenance anxiety around raw cast iron, or have an easier time with stir-frying and maintaining a slick surface, it might be the right wok for you.

Shape and Handles

Q: Should I get a round bottom or flat bottom wok?

A: Unless you have a dedicated wok burner designed to accept a round bottom wok, choose flat-bottomed.

You want a small flat area at the base (about 4–5 inches across) with gently sloping sides flaring out to 12–14 inches at the rim. That preserves the heat concentration in the center while keeping the wok stable on a Western range. This is a great size for typical home use: small enough to be manageable but large enough to cook for a family or a dinner party.

Q: What handle style is best?

Woks traditionally come in two handle styles.

The Northern-style wok (also referred to as a "pow wok") has one long handle and usually a small helper handle opposite it. The long handle makes tossing intuitive—especially if you’re used to Western skillets—and the helper handle makes lifting and pouring safer.

The Cantonese-style wok has two small loop handles. This style is common in restaurant kitchens where the wok sits in a powerful built-in burner and is manipulated mostly with a heavy folded towel and requires a little more effort to toss.

Both styles work. For most home cooks on a Western range, I prefer the Northern-style configuration. The long handle makes maneuvering and tossing easier, and it simply feels more natural in a home kitchen.

Choose the one that fits how you cook—but for flexibility at home, the long handle has the edge.

Wok Hei

Q: What is wok hei?

Wok hei is often translated as “wok breath,” but in practical terms, it’s a set of flavors created by high heat, motion, and the chemistry of a seasoned carbon steel wok.

In an article I wrote for the New York Times (NYT paywall), I identified what I found were the three key elements to developing true wok hei flavor.

Seasoned carbon steelA well-seasoned carbon steel wok promotes rapid evaporation. As food is tossed through the cloud of steam above a hot wok, steam condenses on its surface, rapidly transferring heat before re-evaporating when it hits the metal again. That cycle speeds cooking and concentrates flavor. The polymerized oils on the wok’s surface also contribute subtle grilled, caramelized notes.

Perimeter-seared saucesWhen soy sauce or other liquids are added the proper way—drizzled around the edges of the wok rather than over the food in the center—they sizzle rapidly and undergo rapid caramelization and Maillard browning before being incorporated into the food. This brief searing transforms raw soy sauce flavor into something smokier and deeper.

Burnt, aerosolized oilTiny droplets of aerosolized oil can ignite as food is tossed through flame. With high heat and good technique, that flame can even leap into the wok itself. That combustion deposits faintly charred compounds back onto the food—the same principle as fat dripping onto hot coals under a burger and the smoky bursts of flame it produces.

Q: How can I achieve wok hei at home?

Just as it's difficult to achieve the kind of char and sear you can get at a Western steakhouse cooking meat under an 1,800°F broiler, you can’t fully replicate the effects of a 200,000-BTU restaurant wok range in a standard home kitchen. But you can get surprisingly close by intentionally targeting the three elements that create wok hei.

Here’s how:

Maximize heat concentration.Preheat your wok thoroughly before adding oil. Cook in small batches so the temperature doesn’t collapse. A flat-bottomed wok on a dedicated outdoor wok burner works best (see my guide to outdoor wok burners here), but even a compact butane burner with a 12,000–15,000 BTU/hr rating often performs better than a wide Western burner because it concentrates heat in the center. Heat concentration matters more than raw BTU numbers.

Use the perimeter for sauces.When adding sauce to a stir-fry, splash the sauce or other liquids around the hot rim of the wok rather than over the food the center. You should hear it sizzle aggressively. That quick searing step develops smoky, grilled flavors instead of leaving the sauce tasting raw.

Encourage evaporation.Keep food moving constantly and don't overcrowd the pan. With wok cooking, you are not looking to develop complexity or umami flavors via browning or searing food as you do with Western-style searing techniques. Rather, stir-frying is just about driving off moisture as rapidly as possible. Complexity and umami is added later in the form of deeply-flavored fermented sauces.

Add controlled flame if you want the final element.The hardest part of restaurant wok hei is the flavor of briefly ignited oil droplets. At home, you can approximate this by using a high-output butane torch (I use this one) for a few quick passes over the finished food before final saucing. Alternatively, a powerful outdoor wok burner and good technique will naturally create flare-ups.

If you do nothing else, focus on heat and perimeter-seared sauce. Those two elements alone will dramatically improve the depth and smokiness of your stir-fries.

Seasoning & Surface Development

Q: What should I do when I first get a carbon steel wok?

Most new carbon steel woks come coated in a thin layer of protective oil to prevent rust in storage and shipping. Wash that off with hot, soapy water and plenty of elbow grease before the first use, then set it over a high heat. Rotate the wok all over so all surfaces are exposed to the heat. As you continue to heat it, the metal should start to turn turn bluish-black. What you’re encouraging here is formation of a layer or black iron oxide on the surface of the steel.

If you don't have a gas burner, you can also achieve this blackening by using a blowtorch, a portable butane burner, an outdoor grill, or—if your wok has a removable or oven-proof handle—in a hot oven.

Once the wok is heated and darkened, wipe on a very thin layer of neutral oil, then wipe with a dry paper towel to remove as much of the oil as possible. You're ready to cook.

Note that some woks will come pre-blackened and do not require seasoning before use. Simply scrub off the factory coating and you're ready to go.

With my Super-Nitrided wok, because the nitriding process naturally inhibits rust and corrosion, there is no factory coating at all. The wok is ready to use straight out of the box with just a quick rinse to remove any dust from the packaging.

Q: What’s the difference between seasoning a wok and seasoning cast iron?

This is where most confusion happens.

In Western-style cast iron and carbon steel culture, people often aim to build up thick layers of polymerized oil. That works because these pans are flat and designed to be used at relatively stable temperatures that are even across its surface.

A wok is different.

Wok cooking involves:

Rapid temperature changes

Extremely high localized heat

Constant movement

Frequent transitions between dry and wet cooking

Frequent additions of acidic ingredients like soy sauce and vinegar

These are not ideal conditions for building up the layer of polymerized oil like you with Western cast iron or carbon steel skillets.With wok cooking, the term "seasoning" refers to two things:

Black oxide on the metal surface (I.E. the initial heating/blackening process)

Properly preheating the wok before adding oil and food.

With a wok, you’re not trying to create a glossy, glassy shell. Properly preheating the wok before adding oil and food to it is what gives it its non-stick properties when you cook.

When cooking in a wok, I start by rubbing the tiniest amount of oil into its surface to act as a visual thermometer. After that I preheat the wok empty until it starts to lightly smoke before adding the rest of my oil and beginning to cook.

Q: Do I need to build up thick seasoning layers?

No! It's an exercise in futility and in fact, trying to force thick seasoning layers can make the surface less stable under high heat. The extreme temperature gradients formed in wok cooking and the rapid temperature changes caused by adding sauces means that the metal in a wok expands and contracts in unpredictable ways. This will cause thick layers of seasoning to flake off

The best way to “season” a wok is simply to cook in it regularly, especially relatively dry dishes at first (stir-fries, shallow frying, deep frying). Each cooking session contributes incrementally to surface development.

Q: I braised something in an acidic sauce and now my wok looks gray/metallic instead of black. Is this normal?

Yes! Acidic braises can break down some of the black oxide layer and make your wok look raw. This is OK. Simple heat it again after washing until it re-blackens and you are good to go.

Q: Does the Super Nitride wok change how seasoning works?

Yes — but subtly.

Because the nitriding process alters the steel surface itself, it is:

Harder

More corrosion-resistant

More stable early on

It does not require an initial seasoning ritual. It is ready to cook out of the box.

However, it will still darken and develop a patina over time and use as oils begin to polymerize and cling to the surface. What changes is not the process, but the margin of error. The nitrided layer provides a more stable foundation from the start, reducing the vulnerability that raw carbon steel has, and providing a more stable base for long-term stability.

Q: Why does my wok look uneven or patchy?

Because you're cooking in it! Heat isn’t perfectly symmetrical. Flames hit certain areas harder. Electric and induction elements concentrate heat differently. The center will often darken first. Food and sauces will cool the wok in different patterns.

In that way, a wok is really a living record of how you cook. (Which I think is beautiful)

Everyday Care

Q: How do I clean it a wok?

Rinse with hot water while the wok is still warm—ideally just after use. Use a sponge or a bamboo brush for stuck-on bits. Soap is totally fine if needed. Wipe the wok dry, then set it over medium heat for a minute or two to drive off any remaining moisture.

With traditional carbon steel, that heat-dry step is critical. With Super Nitride, it’s less urgent, but still smart.

Once it looks dry, wipe on the thinnest possible layer of oil, then wipe out as much of it as you can.

That's it!

What Not to Do

Don’t put it in the dishwasher.

Don’t store it wet.

Don’t treat it like a fragile coated pan.

Don’t leave it empty and glowing on high heat for long stretches.

And don’t worry about discoloration. Uneven patina is normal.

If something sticks or looks off, clean it, dry it, add a whisper of oil, and keep cooking.

There's very little you can do to a wok that can't be fixed by simply cooking in it.

Wok FAQs

Q: Will my wok work on induction or electric cooktops?

Yes — with one important condition: it needs to have a flat bottom.

Carbon steel is magnetic, which makes it inherently induction-compatible. As long as the flat portion of the wok makes solid contact with the induction surface, it will heat efficiently. On electric coil or radiant glass cooktops, the same rule applies: full surface contact matters.

The limitation isn’t compatibility — it’s heat concentration. Electric and induction ranges heat only the part of the pan in direct contact with the cooktop while gas will create a gradient that spreads up the sides. More importantly, gas will also continue to work as you toss the wok and lift it, while induction and electric will rapidly lose effectiveness as you move the wok around.

To cook on induction or electric requires a little less motion of the wok itself and more use of a wok spatula to toss and keep the food moving.

The pan will work. You just adapt technique to the heat source.

Q: I see rust. Did I ruin my wok?

No.

Carbon steel rusts because it’s reactive, not because it’s fragile. Surface rust is cosmetic and easily fixed.

Scrub the rust off with steel wool or a firm scrubber until you see clean metal. Rinse, dry thoroughly, then heat the wok on the stove to drive off moisture. Wipe on a very thin layer of oil and continue cooking.

With the Super Nitride version, rust is far less likely because the nitrided surface is more corrosion-resistant. But if standing water sits long enough and you see surface oxidation, the fix is exactly the same. You’re not dealing with a coating that’s been destroyed. You’re dealing with steel. Steel can be restored.

In some rare cases with extended storage in humid environments, rust can work deep enough to cause visible pitting or thinning of the material. This is the only situation in which you may end up needing a new wok.

Q: My food keeps sticking. What am I doing wrong?

Most sticking problems are heat problems.

Carbon steel needs to be fully preheated before oil goes in. To properly preheat a wok, rub the thinnest film of oil into it then set it over high heat. Once the oil starts smoking, add the remaining oil and immediately add your food.

Also remember that wok cooking is about driving off moisture quickly. Excess moisture lowers surface temperature, which increases sticking. If you add food too early or overcrowd the wok, sticking will happen. When stir-frying, It's best to cook in batches, transferring cooked food to a bowl and reheating the wok between batches before adding everything back to the wok for a final sauce-and-toss at the end.

Q: Can I cook tomatoes, vinegar, or wine in my wok?

Yes — just don’t treat it like a slow-simmering enameled Dutch oven.

Quick stir-fries with vinegar, citrus, tomatoes, or wine are completely fine. The exposure is brief, and the seasoning will recover naturally with continued cooking.

Long, slow acidic braises are tougher on a traditional seasoned surface because acid can gradually strip polymerized oil and dull the black oxide layer. If you cook something highly acidic, simply wash the wok promptly afterward, heat-dry it, and wipe on a thin layer of oil if needed.

With my Super Nitrided wok, you have a much more margin for error, since the underlying surface is more corrosion-resistant. But the basic principle remains the same.

Q: What oil should I use?

Any neutral, high-smoke-point oil works for wok cooking: canola, peanut, soybean, vegetable, grapeseed, rice bran, etc.

For some dishes, a specific oil may be called for. Sesame or caiziyu (roasted rapeseed oil), for instance.

Q: My wok looks blotchy or rough. Is that normal?

Yes.

A well-used wok rarely looks uniform. It may have darker patches, lighter metallic areas, rainbow hues from heat exposure, or uneven sheen. The surface evolves based on heat, ingredients, and technique. If it cooks well, releases food properly, and doesn’t rust, it’s doing its job.

Q: How hot is too hot?

For cooking? Very hot is exactly what you want.

Aggressive preheating is good practice but eaving a dry empty wok blasting on high for long stretches doesn’t improve performance and can stress handles or discolor the steel unnecessarily.

The rule is simple: heat it, oil it, and cook.

Q: How long should a carbon steel wok last?

Decades.

There’s no coating to wear out and no bonded layers to delaminate. As long as the handles remain secure, the steel itself can last a lifetime — and then some.

The Super Nitrided version is built with the same expectation. The surface treatment improves durability and corrosion resistance, but the core material is still carbon steel — and carbon steel, when used properly, is extraordinarily long-lived.

Q: Is your Super Nitride wok nonstick?

No. At least not in the traditional sense of the term.

It is not coated. It does not contain synthetic nonstick layers or “forever chemicals.” It is carbon steel that has undergone a nitriding treatment, which hardens and stabilizes the surface and improves early-stage slickness. It still relies on proper preheating, oil, and technique — just like any traditional wok.

What changes is the margin of error. The nitrided surface is more corrosion-resistant and more forgiving, but it behaves like carbon steel because it is carbon steel.
