Preheat the oven’s broiler.

Spread 1/2 of the butter on top side of frozen steak. Sprinkle 1/2 of the Worcestershire sauce, 1/2 of the meat tenderizer, 1/2 of the garlic, salt, and pepper on top of butter. Place steak on a roasting pan or cast iron pan.

Broil in the preheated oven for 6 to 8 minutes. Remove steak from the oven and flip over; spread remaining butter, Worcestershire sauce, meat tenderizer, garlic, salt, and pepper on top of steak.

Return to the broiler, and continue cooking for 6 to 8 minutes, or to desired doneness.
