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 your desired doneness is reached. Remove from heat and let it rest for 5 minutes.
In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 1 minute until fragrant.
Carefully pour in the bourbon and let it simmer for 2-3 minutes, scraping up any browned bits from the skillet.
Stir in the heavy cream, Dijon mustard, and Worcestershire sauce. Bring to a simmer and cook for an additional 5 minutes, stirring occasionally, until the sauce thickens.
Slice the steak against the grain and serve topped with the bourbon garlic cream sauce. Garnish with fresh parsley.
