Is it safe to use cast iron on induction stovetops? Cast iron pans are made of solid and highly magnetic metal. This makes them very suitable for induction cooking. Just make sure the bottom of your cast iron pot has a flat bottom and smooth surface. Also, as most induction cooktops have glass surfaces, using it with your cast iron may need care. For example, try not to slide the cast iron pan while sauteing. Place your cast iron casseroles gently on the stovetop.
