Generously season the steaks on both sides with the seasoning and place in a vacuum sealed bag. Note: use only 1 to 2 steaks per bag.
Boil some water and pour in your ice chest to pre warm it. While the cooler pre-heats, warm 2 - 3 gallons of water to 135 to 140 degrees F. on a stovetop. Pour the water out of the ice chest, then pour in the 140 degree F. water in a Yeti ice chest or an air-tight sealed cooler.
Place the bags of steak in the ice chest and close the lid, let set for at least 2 hours, do not open the lid at this time.
Clean and pre-heat the grill to 450 to 500 degrees F.
Remove steaks from ice chest and bag. Place on the grill. Cook for about 1 to 2 minutes on each side, or until your desired doneness.
Let rest for 4 to 5 minutes and serve.
