Le Creuset Signature Enameled Cast Iron Round Dutch Oven, 5.5 qt, Foret green with gold knob, white background

Le Creuset Signature Enameled Dutch Oven

Name: Le Creuset Signature Enameled Dutch Oven
Brand: Le Creuset

Recommended

Enameled cast iron - the pot itself is fully plastic-free, but the default lid knob is phenolic plastic (easily swapped for a stainless one).

The verdict: No-contact plastic

The pot and lid are enameled cast iron (inert fused glass), so the entire food-contact surface is plastic-free. The only plastic is the default phenolic lid knob, which does not touch food - and Le Creuset sells a stainless steel replacement knob that makes it fully plastic-free.

Verification: Manufacturer confirmed

Lead safety: Lead detected in contact surface

Independent XRF testing by Lead Safe Mama (Tamara Rubin) of Le Creuset enameled cast iron has found lead, cadmium, and antimony in the enamel of some pieces - and notably, this includes trace levels in the food-contact interior enamel of newer items, not just the exterior. Contamination is color-dependent: brighter pigments (yellow, red, green) have tested highest, with cadmium as high as ~17,700 ppm in an exterior yellow enamel and lead as high as ~40,700 ppm in a red glazed piece; lighter colors test lower but Le Creuset has not published which colors are lead/cadmium-free. These results are from testing of Le Creuset enameled cast iron broadly (various pieces and colors), not this specific Signature Dutch Oven or color, and results vary significantly by the exact color purchased.

Verification: Independently lab-tested

The iconic French enameled cast iron Dutch oven, a round braiser-and-pot with a heavy fitted lid, sold in a wide range of sizes and colors. The enamel is a glass surface fused to the iron, so there's no seasoning to maintain and no coating to wear off - you use it for braises, stews, bread, and slow cooking, and it goes from stovetop to oven.

Pros

Food-contact surface is fully plastic-free inert enamel
Lifetime-durable, non-reactive, no seasoning
Plastic knob is trivially upgraded to metal

Cons

Ships with a plastic knob (unlike Staub's metal one)
Default Classic knob limited to 390F until swapped
Independent XRF testing has found lead/cadmium in some enamels, including food-contact interiors - varies by color (see Lead safety)
Heavy and expensive

Make it better

Swap the phenolic lid knob for a stainless steel one

Optional No-contact plastic → Plastic-free trivial

Replace the default black phenolic (plastic) lid knob with Le Creuset's stainless steel knob to make the Dutch oven fully plastic-free and raise the oven limit to 500F.

Unscrew the phenolic knob from the underside of the lid with a small screwdriver
Screw the stainless steel knob into the same threaded hole
Done - the lid is now oven-safe to 500F with no plastic

What to buy: Le Creuset stainless steel replacement knob ($)

The knob is not food-contact even before the swap, so this is about removing the last plastic part and gaining oven temperature, not about food safety
Metal knob gets hot - use a mitt
