Don’t be afraid to sacrifice a splash of whiskey for this rich, smoky steak. The combined warmth of the whiskey and the gusto of garlic in this flavorful, juicy steak recipe are well worth the sacrifice!
In a large zip top bag, combine brown sugar, Dijon mustard, whiskey, balsamic vinegar, olive oil, diced onions, garlic, and black pepper.
Add in the steaks and allow it to marinate in the fridge for at least 4 hours. When ready to cook, bring the steaks to room temperature while preheating the grill on medium-high heat.
Grilling time will depend on desired doneness and thickness of steaks, but once cooked, let the meat rest for 5-10 minutes before serving.
