Yes, it is generally okay to use non-Viking cookware on a Viking induction cooktop. Induction cooktops create a magnetic field that induces a current in the cookware, generating heat. As long as your non-Viking cookware is compatible with induction cooking, it should work just fine on the Viking cooktop. To determine compatibility, check if your cookware has a magnetic bottom, such as stainless steel or cast iron. Avoid using cookware with non-magnetic materials like aluminum or copper, as they won't heat up on an induction cooktop. Using appropriate cookware will ensure efficient and safe cooking on your Viking induction cooktop without any issues.
