Kitchen

Heat plus plastic equals leaching. Five interfaces every home has, none of them necessary.

A 2022 NIST study estimated that a typical household plastic cutting board sheds 7 to 50 grams of microplastic per person per year, directly into food being prepped on it. A 2019 McGill study found that a single nylon pyramid teabag releases roughly 11.6 billion microplastic particles into the cup at brewing temperature. The kitchen is where plastic and heat meet most often, and where the daily dose is hardest to argue with.

We're not interested in the ceramic-coating wars. The brands change formulas, the chemistry isn't independently audited, and a Lodge skillet that lasts a generation costs less than three rounds of replacing whatever is in the cabinet now. The fifteen picks below are the materials restaurants have used for a hundred years: cast iron, stainless, carbon steel, solid ceramic, hardwood, glass.

What earns a spot

  • Cookware made of one material, not coated (cast iron, stainless, carbon steel, solid ceramic)
  • Hardwood at the cutting interface, end-grain preferred for self-healing under daily knife work
  • Glass body, platinum silicone, or stainless for any container that touches hot food

What gets rejected

  • Older Teflon and current "ceramic-coated nonstick" pans (Caraway, GreenPan, Always Pan): proprietary chemistry, no independent audit
  • Plastic cutting boards (NIST 2022, ~50 grams of microplastic shed per person per year)
  • Pyramid or silken teabags (McGill 2019, ~11.6 billion particles per cup) and single-pod coffee machines
  • Black plastic kitchen tools (Amsterdam 2024, flame retardants from recycled electronics that leach at cooking temperatures)

Matfer Bourgeat Carbon Steel 11"Our pick
pan

Matfer Bourgeat Carbon Steel 11"

Our pick for the everyday pan. Restaurant-grade carbon steel: same zero-coating chemistry as cast iron, half the weight, seasons in two cooks. The pan most pro kitchens reach for daily.

  • Lightweight (3 lbs)
  • Seasonable
  • Made in France
  • Restaurant-grade
WhyCarbon steel is the working answer to the everyday pan question. Same zero-coating, zero-PFAS chemistry as cast iron. Half the weight of Lodge (3 lbs vs 5.7), so you'll actually use it. Develops a non-stick patina faster than cast iron because the metal is thinner. Used in more professional kitchens than any other pan in the world.

Smithey Carbon Steel Farmhouse Skillet

The heirloom carbon steel skillet. Hand-forged in Charleston, SC. PFOA and PTFE free. Same zero-coating chemistry as Matfer, in a hand-hammered American-made body with a lifetime guarantee.

  • Hand-forged
  • Made in Charleston, SC
  • Lifetime guarantee
  • PFOA/PTFE free
WhySmithey's carbon steel is the premium step up from Matfer for the buyer who wants an American-made, hand-finished pan they'll pass down. Same chemistry as our pick (carbon steel, no coating, no PFAS), with a forged handle and a lifetime guarantee.

Le Creuset Signature Cast Iron Everyday Pan 11"Premium pick
pan

Le Creuset Signature Cast Iron Everyday Pan 11"

Enameled cast iron. The enamel surface is glass-like: zero coating chemistry, acid-tolerant, dishwasher-safe. Different category from bare cast iron.

  • Enameled surface
  • Made in France
  • Acid-tolerant
  • No seasoning required
WhyEnameled cast iron occupies a different lane: the porcelain enamel surface is non-reactive, so unlike bare cast iron you can deglaze with wine, simmer tomato sauce, and use without seasoning maintenance. Same heat retention as cast iron, brand pedigree, Amazon-channel availability.

Made In 10-Piece Stainless Set

Full 5-ply stainless cookware set. Frying pan, saucier, stockpot, sauté pan, plus lids. Made in France and Italy. Sold direct to consumer, no retail markup.

  • 5-ply construction
  • Induction-compatible
  • Oven-safe to 800°F
WhyThe complete-kitchen swap. If you're replacing nonstick across the board, the 10-piece set is meaningfully cheaper than buying each piece separately, and the consistency across the set (handle weight, finish) is something you only get from a single-brand purchase.

Chemex Classic Pour-Over 8-Cup

The iconic all-glass pour-over. No plastic in the water path, paper filter chain. The clean coffee brewing answer for forty years and counting.

  • All-glass body
  • Paper filter
  • Museum of Modern Art collection
WhyChemex is the canonical plastic-free coffee setup. The whole brewer is borosilicate glass; the only non-glass parts are the wooden collar and the rawhide tie around the neck. Paper filters mean no plastic in the brewing surface either.
