A flavorful twist on grilled steaks with a tropical-inspired marinade.
Combine the rum, salt, pepper, cinnamon, garlic powder, oregano, sage, vinegar, and lemon juice in a mixing bowl.
Mix the ingredients thoroughly to ensure an even distribution of flavors.
Place the steaks and onion slices into a resealable plastic bag and pour the marinade over them. Seal the bag, removing excess air.
Massage the bag gently to coat the steaks evenly with the marinade.
Refrigerate the bag for 3 to 4 hours to allow the flavors to infuse into the meat.
Turn the bag occasionally to ensure even marination.
Preheat your grill to medium-high heat. Remove the steaks from the marinade and let excess drip off.
Oil the grill grates to prevent sticking.
Grill the steaks for about 4 minutes on each side for medium-rare, adjusting the time for your preferred doneness.
Use a meat thermometer to check the internal temperature for precise doneness.
Let the steaks rest for 5 minutes before serving to retain their juices.
Cover the steaks loosely with foil while resting to keep them warm.
