A:Answer Hi June! Thank you for your question about model GCRE3060BF. For the smooth glass cooktop, we recommend using a flat-bottom griddle that is specifically labeled as safe for glass cooktops, such as heavy aluminum or stainless steel with a smooth, non-warped base; avoid rough cast iron unless it is enameled and perfectly smooth to prevent scratching. For air frying, a compatible option is the Frigidaire ReadyCook™ 30" Air Fry Tray, which sits on the oven rack and allows proper air circulation, typically with a sheet pan placed underneath to catch drippings. If you prefer not to use the tray, a dark, low-sided baking sheet can also work well with the oven’s Air Fry mode. — Reed
