Cook the Steaks: Place a cast-iron skillet over high heat. Once the skillet is very hot, add the marinated steaks.
Sear: Sear the steaks for 5 to 8 minutes on one side, then flip them.
Cook to Desired Doneness: Cook for 3 to 4 minutes on the other side for medium to well-done steaks. Adjust cooking time for your preferred level of doneness.
Rest: Remove the steaks from the skillet and let them rest for 5 minutes.
Finish: Top the rested steaks with butter.
Serve: Serve immediately with your favorite sides and garnish with freshly chopped parsley. Enjoy!
