Using a cast iron skillet on a glass top stove is possible, but it requires some care to prevent damage to both the stove and the skillet. Here are some tips to use a cast iron skillet on a glass top stove without ruining it:
Check compatibility: Ensure that your cast iron skillet is flat and smooth on the bottom. Some older or poorly manufactured cast iron skillets might have rough bottoms that could scratch the glass surface. If your skillet has any rough spots, it's better not to use it on a glass top stove.
Clean both surfaces: Before placing the skillet on the glass top, make sure both the glass surface and the bottom of the skillet are clean and free of any debris. Dirt or grit between the two surfaces could cause scratches.
Lift, don't slide: When moving the skillet on the glass top stove, avoid sliding it as much as possible. Lift the skillet instead to prevent scratching the glass.
Preheat the skillet carefully: Preheating the cast iron skillet on a glass top stove requires special attention. Start with low to medium heat and gradually increase the temperature as needed. Rapidly heating the skillet could lead to uneven expansion and potentially crack the glass surface.
Use a lower heat setting: Cast iron retains heat very well, so you usually don't need to use high heat with it. Once the skillet is preheated, lower the heat setting to maintain even cooking. This is especially important because cast iron's heat retention may lead to prolonged high heat, which can be damaging to the glass surface.
Avoid dropping the skillet: Dropping a heavy cast iron skillet on a glass top stove can cause severe damage to the glass. Be cautious when handling the skillet to prevent any accidental drops.
Use flat-bottomed cookware: If possible, opt for cookware with flat and smooth bottoms. This includes enameled cast iron or stainless steel, which are typically safer options for glass top stoves.
Consider a heat diffuser: To further protect your glass top stove, you can use a heat diffuser or a cast iron skillet ring. These accessories help distribute the heat more evenly and reduce direct contact between the cast iron skillet and the glass surface.
Clean with care: After cooking, allow the skillet and stove to cool before cleaning. Avoid using abrasive pads or harsh cleaners that could scratch the glass top.
Remember that using cast iron on a glass top stove is always a bit riskier than other cooktop materials, so exercise caution and be attentive during the cooking process. If you're concerned about potential damage, consider using alternative cookware options on your glass top stove.
