Use medium heat, don't overcrowd.

Maintaining medium heat is important for searing meat in stainless steel without sticking. High heat can cause meat to cook too quickly on the surface and stick before it has a chance to sear and release. Overcrowding the pan is also detrimental as it lowers the pan temperature, leading to steaming instead of searing, which significantly increases the likelihood of sticking. Cooking in batches at medium heat ensures proper searing and reduces sticking.
