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, add the minced garlic and sauté for about 1 minute until fragrant.
Carefully pour in the bourbon, scraping up any browned bits from the bottom of the pan. Allow it to simmer for 2-3 minutes until slightly reduced.
Stir in the heavy cream and Dijon mustard, and let it simmer for another 5 minutes until the sauce thickens.
Slice the rested steak and serve it topped with the bourbon garlic cream sauce. Garnish with fresh parsley.
