the Instant Pot brand primarily offered multi-cookers with a non-stick interior. The non-stick coating made cleaning more comfortable and prevented food from sticking to the pot. However, some users were concerned about the safety of non-stick coatings at high temperatures and their potential health risks when they wear off over time.
To address these concerns, Instant Pot introduced a stainless steel insert option for some of their models. Stainless steel is a durable, non-reactive material that does not require a non-stick coating. It is generally considered safer for cooking at high temperatures and is easier to maintain in the long run.
Instant Pot models with a stainless steel insert are often referred to as "Instant Pot Duo Stainless Steel" or similar names. The stainless steel insert provides an alternative for users who prefer a non-stick-free cooking surface.
Keep in mind that product offerings and features may change over time, so I recommend checking the Instant Pot website or consulting with the manufacturer to confirm the availability of specific models with a stainless steel insert. Additionally, other brands may also offer multi-cookers with stainless steel inserts or entirely non-coated interiors, providing further options for those seeking non-stick-free cooking surfaces.
