How to Use Cast Iron on a Cooktop Stove

Cast-iron cookware should be used with care on cooktop stoves.

Cooks can safely use cast iron on a glass or ceramic cooktop stove as long as the pot or pan bottom is clean and flat, according to the Cookware Manufacturer's Association. Cast iron absorbs and retains heat, making it a traditionally popular form of cookware. High heat transfer and poor heat distribution between the cooktop and the pan bottom can damage a cooktop's heat sensors. Some manufacturers such as GE don't recommend using cast-iron cookware on cooktops. Also avoid ring-bottomed cast iron on your cooktop.

Things You'll Need

• Cooktop cleanser
• Heat-proof potholders
• Flat-bottomed pots and pans

Instructions

1. Clean your cooktop surface according to the manufacturer's instructions. Grit or dried-on food debris on a cooktop surface can contribute to scratches.

2. Inspect your cast-iron pan bottoms before placing them on the cooktop. Use only smooth-bottomed pots and pans. Don't use pans that have warped or ridged bottoms, as they will not cook evenly.

3. Center the cookware on the heating element. Allow the pan to heat very slowly on the lowest setting. Never use high heat settings with cast iron on a cooktop.

4. Use potholders or oven gloves to handle cast iron. Remove the pan promptly when food is nearly fully cooked. Cast iron retains heat and will continue cooking your food for a minute or two after you've removed it from the heating element.

Tips & Warnings

• To avoid scratching your cooktop, never drag, scoot or scrape a cast-iron pan across a cooktop. Don't drop any pans onto the glass as you may crack the cooktop surface.
