Cookware (Pots, Pans, Bakeware)

Cookware is where material meets the most heat — which makes it arguably the most important category in the kitchen. High temperatures change how a surface behaves and what it can release into food, and the same heat that cooks dinner can also break down a coating or dissolve metal from a reactive pan. Choosing the right material here pays off three times a day.

Recommended Materials

Stainless steel — the versatile default

Food-grade stainless steel (look for 18/8 or 18/10, i.e., grade 304) is the most practical all-rounder: durable, non-reactive enough for everyday use including acidic dishes, oven- and dishwasher-safe, and effectively shatterproof. A tri-ply pan (stainless–aluminum–stainless) sandwiches a conductive aluminum core between steel layers for even heating without exposing food to the aluminum.

What to consider: stainless steel can release small amounts of nickel and chromium, most noticeably with acidic foods and long simmer times, and most from brand-new pans; leaching drops sharply after the first several uses (Kamerud et al. 2013). Amounts are safe for most people; those with a nickel allergy may prefer enameled cast iron or glass for long acidic cooks.

Enameled cast iron — inert surface, no break-in

Enameled cast iron wraps the heat retention of cast iron in a glass (porcelain enamel) coating that is essentially inert. It doesn't react with acidic food, needs no seasoning, won't rust, and is ideal for braises, sauces, and long simmers — with no real downside beyond weight and price.

What to consider: the enamel can chip if dropped or struck; once the bare iron is exposed, treat it like bare cast iron (or retire it for acidic cooking). Avoid aggressive high-heat dry searing, which can craze some enamels over time.

Bare cast iron & carbon steel — durable, and they add iron

Bare cast iron and carbon steel develop a naturally slick seasoned (polymerized oil) surface, retain heat beautifully, and last for generations. A genuinely useful side effect: cooking in them, especially acidic dishes, transfers iron into food and can meaningfully raise dietary iron intake — a benefit for many people, including those prone to iron-deficiency anemia (Sharma et al. 2021).

What to consider: they require seasoning and dry storage to prevent rust, and the added iron, while harmless for most, is worth noting for anyone with iron overload (e.g., hemochromatosis). Bare iron is also reactive, so very acidic dishes can taste metallic and strip seasoning — use enameled cast iron or stainless for those.

Glass & ceramic bakeware — inert in the oven

Tempered glass and glazed ceramic are inert, non-reactive, and non-leaching, making them excellent for baking and oven-to-table dishes.

What to consider: both are vulnerable to thermal shock — avoid moving them between temperature extremes (e.g., a cold dish into a hot oven, or a hot dish onto a wet counter), which can cause them to shatter.

In short: stainless steel handles most stovetop cooking, enameled cast iron and glass cover acidic and oven dishes with a fully inert surface, and bare cast iron or carbon steel reward a little maintenance with great performance — none of which depends on a non-stick coating.

Key Findings

• Conventional non-stick is PTFE, and legacy versions were made using PFOA. PTFE (polytetrafluoroethylene, "Teflon") coatings were historically manufactured with PFOA, a persistent compound since phased out of production under a 2010/2015 EPA stewardship program (Sajid & Ilyas 2017). In a highly exposed community, the C8 Science Panel found probable links between PFOA and high cholesterol, thyroid disease, ulcerative colitis, pregnancy-induced hypertension, and kidney and testicular cancer (Barry et al. 2013).
• PTFE breaks down and releases fumes when overheated. Above roughly 260 °C (500 °F) PTFE begins to degrade and can emit gases that cause polymer fume fever ("Teflon flu") — a transient flu-like illness — with the highest risk from preheating an empty pan (Sajid & Ilyas 2017; Polymer Fume Fever, StatPearls 2024).
• Bare cast iron adds iron to food. Cooking — especially acidic, longer-simmered dishes — measurably increases the iron content of food and can improve blood iron status, which is why bare iron is treated as a benefit rather than a risk for most people (Sharma et al. 2021).
• Uncoated aluminum reacts with acidic food. Acidity and long, hot contact dissolve aluminum's protective oxide layer and increase migration into food; exposure from cookware is usually a modest fraction of total dietary aluminum, but anodized or lined surfaces avoid the direct contact (Sultan et al. 2023).

Materials to Avoid + Risks

• Scratched or flaking non-stick pans. Once the coating is damaged it sheds particles and loses its protective function — retire the pan. Never use metal utensils or abrasive scrubbers on any non-stick surface.
• Overheating non-stick. Don't preheat an empty non-stick pan or use it for high-heat searing; coatings are most vulnerable when dry and very hot (Sajid & Ilyas 2017).
• Vague "non-toxic coating" claims. Some ceramic-style (sol-gel) coatings wear out quickly; treat durability and clear material disclosure as part of the decision rather than the marketing label.
• Reactive bare aluminum or unlined copper with acidic foods. Use anodized, lined, or coated versions for tomato- and citrus-heavy cooking (Sultan et al. 2023).

Make non-stick optional

A stainless steel pan plus a well-seasoned cast iron or carbon steel pan covers nearly everything most cooks do, reducing reliance on coated cookware altogether. If you do keep a non-stick pan, reserve it for low- and medium-heat tasks like eggs.

Practical Tips

• Learn to preheat stainless steel properly (the water-droplet "Leidenfrost" test) — it dramatically reduces sticking with no coating needed.
• Season and maintain cast iron and carbon steel; a good patina is its own non-stick layer, and drying the pan after washing prevents rust.
• Use wood, silicone, or nylon utensils on any coated or enameled surface to avoid scratches and chips.
• Keep any non-stick pan to low and medium heat, never empty on a hot burner, and ensure good kitchen ventilation.
• Cook acidic dishes (tomato, citrus, wine) in stainless, enameled cast iron, or glass rather than bare aluminum, unlined copper, or unseasoned iron.
• Choose glass, ceramic, or uncoated steel for baking when possible.
• Retire non-stick cookware once it's scratched, pitted, or flaking.
