Use & Care Can I Use Cast Iron on an Induction Cooktop? By: Lodge Cast Iron / June 22, 2022 Using cast iron on induction often raises questions—and we’ve got answers. Induction uses magnetic fields to heat cookware, so your pan must contain conductive, ferrous metals to transfer heat. This makes cast iron a great option for induction cooking. While it’s perfectly safe to use our cookware on these cooktops, they do function differently than gas and electric, so there are a few things to consider before you start cooking.

If you heat your skillet too quickly, the temperature of the iron can become imbalanced, causing thermal shock. In severe cases, this can cause cookware to break on the stovetop. To avoid this, just preheat your cookware slowly with oil. When the oil shimmers and ripples, your skillet is ready to go. If the oil begins to smoke, your cookware is too hot and it’s best to remove it from the heat source for a minute or two to cool down before cooking. Does the size of my cookware matter? Choose a piece of cookware that’s closest to the size of the burner you’re using to ensure even heating. This is helpful on gas and electric cooktops, but it’s a bit more important on induction. Many induction cooktops are designed with a safety feature that detects the size of your cookware. If your skillet is too small compared to the size of the burner, the induction cooktop might not be signaled to heat up. Every cooktop is different—check with your manufacturer for specific details and best practices. Does my skillet need to be in full contact with the burner? Contrary to popular belief, your cookware doesn’t need to come into full contact with the induction burner in order to heat. Some pieces are created to sit flush, or nearly flush, with your burner. Other pieces are designed with a heat ring, which creates a small gap between the pan and the burner. Don’t worry—a few millimeters of distance between the cookware and the burner won’t affect the overall performance. If you’re using a larger griddle, like a reversible grill/griddle, it can be helpful to use a “bridge” burner that sends heat to the gap between the main burners. This helps your cookware to heat evenly and reduces the risk of thermal shock. If the distance between the outside edge of the cookware and the cooking surface is too large for the product to heat efficiently, you may need to switch to a piece that is closer to the size of your burner. Will cast iron scratch the induction stove’s glass top? This is a concern for people who use a glass-top cooking surface—induction or electric. The bottom of our cookware is cast to be very smooth and shouldn’t scratch your stovetop. However, when moving your skillet from burner to burner, we recommend that you gently pick it up and set it back down, rather than slide it from one burner to another.
