Lodge enameled Dutch ovens are oven-safe up to 500°F. The company doesn't state the oven-safe temperature of the bare cast iron Dutch ovens, but I spoke with a Lodge product specialist. Here’s what they told me: “Our cookware is seasoned with baked-on cooking oil. We recommend using Lodge cookware up to 500°F because anything higher can start to break down the seasoning. However, the cast iron can withstand higher temperatures, but you may have to re-season if used over 500°F.”
