Season the meat with salt and pepper (optional, you can also apply a BBQ rub) Let it rest in the refrigerator for about an hour.
Preheat the Traeger to a 205°F with super smoke on.
Use a paper towel to pat the steak dry.Place the steaks on the smoker grates, the steaks will need approximately one hour, although the exact cooking time can vary significantly based on factors.You should use a leave-in thermometer to monitor the cooking progress accurately.I was going for medium rare, this means you need to cook the steaks until they reach an internal temperature of about 130°F (54°C) in the center. I have included a table below for levels of doneness. As soon as the steaks reach this temperature, remove them from smoker and rest for 10 minutes
While this is happening, preheat your or cast iron pane or griddle to 500°F. Filet mignon requires a very hot grill and direct heat, this allows the meat to cook quickly without overcooking.So it is crucial to get the grill hot before putting steaks on the grill. All you want to do is brown the meat for 30-60 seconds on each side.
Allow the meat to rest 5-10 minutes before serving.
