The Crucial Cast Iron Mistake Ruining Your Steak (And How To Actually Fix It) - Tasting Table
Briefly

To achieve a delicious sear on steak using a cast iron pan, maintain the pan temperature between 280 and 330 degrees Fahrenheit. High temperatures can burn the outside while leaving the inside raw. The ideal stovetop setting is medium-low, around a dial setting of three to four. Using an infrared thermometer can help ensure the correct temperature. Additionally, choosing the right oil is crucial, as heating above 400 degrees can cause oils to burn and negatively affect the steak's flavor.
