Yes! The stainless steel on our lids is 100% microwave-safe due to its smooth, curved shape. It may sound nuts, but some metal is totally safe in microwaves. It depends on how it is shaped, i.e. if the metal is rounded, it won't arc. A smooth, stainless steel bowl, for example, is fine! But don't put in metal that is super thin (e.g. aluminum foil) or has multiple sharp corners (e.g. a fork). Science doesn’t lie!
Just make sure your Anyday dish is placed at least one inch away from your microwave's wall. If the stainless steel rim of your lid gets too close, it can cause sparking.
