Canning at home is an incredibly rewarding way to preserve fresh ingredients, but it often presents a unique challenge for users of modern glass cooktops.
Finding a pot that is compatible, efficient, and won’t scratch or damage your smooth surface can be frustrating and unsafe.
We’ve evaluated dozens of models to bring you the best canning pots engineered to perform flawlessly on glass cooktops, prioritizing safety, performance, and convenience.
These top picks, selected by appliance expert Chris Walkar, ensure seamless and successful food preservation.
1. 21.5-Quart Speckled Black Waterbath Canner
