Preheat your grill or skillet over medium-high heat. Rub the steak with olive oil and season generously with salt and pepper.
Cook the steak for about 4-5 minutes on each side for medium-rare, or until it reaches your desired doneness. Remove from heat and let it rest for 5-10 minutes.
In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 1 minute until fragrant, being careful not to burn it.
Carefully pour in the bourbon and let it simmer for 2-3 minutes, scraping up any browned bits from the bottom of the skillet.
Stir in the heavy cream, Dijon mustard, and Worcestershire sauce. Allow the sauce to simmer for an additional 5-7 minutes until it thickens slightly.
Slice the rested steak against the grain and serve topped with the bourbon garlic cream sauce. Garnish with fresh parsley.
