Nonstick is the most popular cookware in American kitchens, and the reasons are obvious: food doesn't stick, cleanup is easy, and the barrier to entry is low. For a long time, nonstick was also the only reasonable answer to rough, heavy cast iron that took years to develop a functional cooking surface. That calculus has changed. Premium cast iron from makers like Field—machined smooth, properly pre-seasoned, and engineered to be lighter—has closed the gap that made nonstick feel necessary. Understanding what nonstick actually costs you—in performance, in longevity, and in what ends up in your food—makes the choice considerably clearer.

The short version: you don't really need a nonstick pan. It has its uses—it asks nothing of you, no learning curve, and no patience required, which is the whole appeal, and for a crepe or a first attempt at eggs that's a fair trade. But cast iron is a tool you learn, and it pays you back for it: it does nearly everything most people cook, it lasts indefinitely, and unlike nonstick, it gets better every time you use it.

The case for nonstick

Nonstick cookware is coated with a synthetic material, most commonly PTFE (polytetrafluoroethylene, marketed as Teflon), that creates a slick, low-friction surface that food releases from easily, even without much fat. More recent "ceramic" nonstick pans use a silica-based coating marketed as a cleaner alternative, though the performance and durability claims vary widely by brand, and independent researchers have questioned the validity of their nontoxic claims. Either way, the appeal is the same: easy food release, easy cleanup, low technique requirement.

For certain tasks, particularly delicate ones, nonstick genuinely is the easiest tool. Crepes slide out perfectly. Eggs require almost no fat and no technique. Thin fish fillets release without tearing. For a beginning cook who hasn't yet built up a seasoned cast iron surface or spent time learning how to use their cookware, nonstick removes a real source of frustration.

Advantages

1.

Immediate food release. Nonstick releases food with little to no fat from day one. For folks who want that without having to think about cooking fat, temperature control, or seasoning, that immediacy is the core appeal.

2.

Low technique requirement. You can cook eggs on an underheated nonstick pan with too little fat and they'll still release. The coating compensates for technique in a way that cast iron, and stainless, doesn't. For beginners or low-stakes weeknight cooking, that forgiveness is real.

3.

Easy cleanup. Food rarely sticks enough to require scrubbing, and most nonstick pans wipe clean with minimal effort. No oil required after washing, no drying routine—though most manufacturers still recommend hand washing to prolong the effectiveness of the coating.

4.

Low entry price. Inexpensive nonstick pans are widely available and perform reasonably well when new. For a cook who isn't ready to invest in premium cookware, the low barrier to entry is a genuine advantage.

Who it's right for

Nonstick is the right tool for a narrow set of tasks: crepes, very delicate fish on an unseasoned pan, and eggs for cooks who haven't yet developed a cast iron seasoning. It's also a reasonable choice for beginning cooks who want to remove as many variables as possible while learning. What it isn't is a foundation—it's a limited-purpose pan that works best when treated as a supplement to a more capable primary pan, not a replacement for one.

The case for cast iron

Cast iron starts as an alloy of iron and carbon, melted down and poured into a mold in a single pour. What comes out is one continuous piece—no joints, no layers, no bonded surfaces to separate or fail. Just iron, cooled into the shape of a pan, with nothing to wear out and nothing to replace. The process is essentially unchanged from how it was done centuries ago. That kind of durability tends to be self-explanatory.

The property that defines how cast iron cooks is heat retention. It takes longer to get hot than other materials, but once it's there, it holds. Drop a cold steak into a properly preheated cast iron pan and the surface temperature barely registers the impact—the mass of the iron absorbs it and keeps cooking. That's what builds a real crust. Stainless and nonstick drop in temperature when cold food hits them; cast iron doesn't, which is the difference between a sear and a steam.

The other thing that sets cast iron apart, and that no other material does the same way, is seasoning. Cook in it regularly and fat polymerizes into the iron, building up a nonstick layer that gets more effective over time. Not nonstick in the way that requires the right temperature and the right amount of oil to work, but genuinely nonstick: eggs that slide, fish that releases, a surface that keeps improving the longer you use it. There's no coating involved and nothing to degrade. It just gets better.

Advantages

1.

Heat retention. The mass of a cast iron pan works like a thermal reservoir—it absorbs heat slowly and gives it back steadily. That consistency is what makes it so effective for searing, frying, and any cooking where you want contact heat to stay constant when food hits the surface. Other pans drop in temperature and recover; cast iron holds and keeps cooking. It's also why cast iron is the wrong tool if you need to drop temperature quickly—that heat retention works both ways.

2.

A surface that improves over time. Most cookware performs best when it's new and declines from there. Cast iron runs the opposite direction. A pan that's been used daily for five years performs better than it did on day one, and better still after ten. The seasoning deepens, food release improves, and the pan becomes increasingly forgiving and easy to cook on. That trajectory is unique to cast iron, and it's the reason people pass these pans down.

3.

Longevity. There are Wagner and Griswold skillets from the early 1900s still in active use in home kitchens today. Cast iron doesn't wear out—it just gets older. With basic care, a cast iron pan will outlast everything else in your kitchen and remain useful for whoever inherits it. The average nonstick pan lasts two to five years before the coating degrades past the point of usefulness and safety, which means a 20-year cooking life runs through four or five of them—and every one of them ends up in a landfill.

4.

No coatings. The cooking surface is iron and seasoning, nothing else. No synthetic compounds, no PTFE, no ceramic layer that chips or flakes, nothing that degrades with heat and ends up in food over time. For cooks who care about what their cookware is made of and what it's doing to their food over years of use, cast iron is the straightforward answer.

5.

Versatility. Cast iron works on any heat source—gas, electric, induction, glass top—and moves to the oven, grill, or open fire without any adjustment or temperature limit. Nonstick pans are restricted to around 400–500 degrees before the coating begins to break down, which rules out high-heat searing, broiling, and most outdoor cooking entirely.

Who it's right for

Cast iron is the right primary pan for most home cooks—not as a compromise, but as the better choice for the majority of everyday cooking. It handles searing, frying, baking, and eggs better than any other material, and its performance improves with use in a way nothing else matches. The maintenance requirement is real but modest: dry it after washing, apply a light coat of oil, store it properly. For cooks who cook regularly, that routine becomes second nature quickly.

A note on coating concerns

This is worth addressing directly, because the conversation has changed significantly in recent years.

The original nonstick coating, PTFE, marketed as Teflon, is considered stable at normal cooking temperatures, but begins to break down above approximately 500°F, releasing fumes that are harmful to birds and can cause flu-like symptoms in humans at high concentrations. An empty nonstick pan left on a high burner can reach those temperatures in minutes. PTFE is also bonded to pans using PFAS compounds, the class of "forever chemicals" that have been found to accumulate in human tissue and are now the subject of major regulatory action. In 2024, the EPA designated PFOA and PFOS—PFOA being the compound historically used to make nonstick coatings—as hazardous substances under the federal Superfund law. PFAS compounds are increasingly restricted under state and federal law, and the regulatory environment around them is tightening.

Most modern nonstick manufacturers have moved away from PFOA specifically, but PFAS is a broad chemical class and "PFOA-free" does not mean PFAS-free. Minnesota banned the sale of cookware with intentionally added PFAS outright in 2025, with similar restrictions phasing in across Colorado, Maine, Rhode Island, and Connecticut through 2028.

Ceramic nonstick is marketed as a cleaner alternative, but "PFAS-free" and "non-toxic" claims are largely unverified by independent testing, and ceramic coatings typically degrade faster than PTFE, losing their nonstick properties within a year or two of regular use. Hybrid "honeycomb" pans—a stainless steel lattice with nonstick coating set in the valleys—make the same pitch, but the food still releases off a coating, not the steel. The most popular of them, HexClad, used PTFE until 2024 and switched to ceramic only after a class-action lawsuit challenged its non-toxic marketing—a useful reminder that the category's claims tend to move faster than the testing behind them.

None of this is reason for alarm about pans you've used in the past. But for cooks who are thinking about what they want to be cooking on for the next 20 years, it's a real consideration, and one that cast iron sidesteps entirely.

Cast iron vs. nonstick: our take

Nonstick solved a real problem: rough, heavy cast iron that was difficult to cook on and frustrating to maintain. That problem is largely solved by modern machined cast iron, which develops a genuinely nonstick surface faster, performs better at high heat, and lasts indefinitely. The tradeoff nonstick asks you to make—coating concerns, temperature limits, eventual replacement—makes less sense when the alternative has caught up.

That said, nonstick has earned its narrow place. For crepes, for a beginner's first eggs, for delicate fish before a cast iron seasoning is established, it's the most forgiving tool for those specific tasks. What it shouldn't be is the foundation of a kitchen, or the pan you reach for when the cooking gets serious.

The honest version: nonstick is a convenience tool with a built-in expiration date. Cast iron is a cooking surface that compounds—getting better, more nonstick, and more valuable every time you use it. Over any meaningful time horizon, there's no comparison.

What to cook in each

Reach for cast iron for:

  • Searing steaks, chops, and chicken thighs
  • Frying—chicken, potatoes, anything that benefits from steady oil temperature
  • Eggs, once the seasoning is established
  • Cornbread, skillet cookies, and oven baking
  • Smash burgers
  • Anything that starts on the stovetop and finishes in the oven
  • Cooking over a grill or open flame
  • Any dish that requires high heat

Reach for nonstick for:

  • Crepes and thin pancakes
  • Eggs for beginner cooks or before cast iron seasoning is established
  • Very delicate fish fillets that tear easily
  • Low-heat cooking where sticking is the only concern

A note on cast iron quality

Not all cast iron is made the same way, and the difference that matters most is the one you can't see until you cook on it: the surface. Wagner and Griswold pans from before World War II were machined smooth after casting—that's why they built seasoning faster, released food more cleanly, and felt better in the hand than the cast iron that came after. As mass production scaled up, most manufacturers moved away from that step to cut costs and increase volume, and the rough, pebbly surface that became the modern standard was the tradeoff.

A modern cast iron skillet with a machined surface picks up where those vintage pans left off. It seasons faster, builds nonstick performance more quickly, and requires less break-in time than rough-cast alternatives, because the surface is doing what it was always supposed to do. Surface finish is the single biggest factor in how quickly a cast iron pan develops and how well it performs in the early months. It's why we built Field the way we did.
