“Does cast iron work on induction?” The short answer is that most bare cast iron cookware will not perform well, or at all, on an induction cooktop unless it has a magnetic base specifically designed for the technology.
While induction requires ferromagnetic material to heat efficiently via electromagnetism—a property some quality cast iron possesses—the thick, heavy nature of traditional pieces can lead to uneven heating across the surface if they are not engineered with suitable bases. If your piece is solid and has a wide contact area, you may notice hot spots or an inconsistent heat transfer, which severely compromises the searing process we want.
If you find that your pan warps slightly when exposed to intense induction heat for prolonged periods, it’s a sign that its structural integrity might be compromised for this specific cooking method. The trade-off here is simple: superior performance on induction often requires a specialized iron or steel core beneath the cast surface.
Preparing the Iron
The foundation of using cast iron well is proper seasoning, which essentially creates a polymer layer of fat onto the metal that prevents sticking and b
