Ingredients

  • 4 x 8 oz sirloin steaks, at least 1 inch thick, preferably 1.5 inches
  • Salt and black pepper, to taste
  • Olive oil, for grilling or searing

For the Creamy Whiskey Peppercorn Sauce:

  • 1 tablespoon olive oil
  • 1 shallot, finely chopped
  • 2 cloves garlic, minced
  • 2 cups beef stock
  • 2 tablespoon black or green peppercorns, lightly crushed
  • ¼ cup cream
  • 2 tablespoon whiskey
  • 1 tablespoon butter
  • Salt and pepper, to taste

Instructions

Prepare the Steaks:

  • Let the sirloin steaks sit at room temperature for about 30 minutes for even cooking. Season both sides generously with salt and black pepper.

Cooking Method - Grilling:

  • Preheat your grill to high heat (about 500°F). Brush the grill grates with olive oil.
  • Grill the steaks for about 2-3 minutes per side for a medium-rare finish, or adjust according to your preferred level of doneness.

Cooking Method - Pan-Searing:

  • Heat a heavy skillet (cast iron preferred) over high heat. Add a tablespoon of vegetable oil.
  • Once hot, add the steaks, searing for 2-3 minutes on each side for medium-rare, adjusting as needed for your preferred doneness.

Rest the Steaks:

  • Transfer the cooked steaks to a plate. Tent loosely with foil and let them rest for at least 5 minutes.

Make the Whiskey Peppercorn Sauce:

  • In a medium saucepan, heat 1 tablespoon of olive oil over medium heat. Add the finely chopped shallot and minced garlic, cooking until soft and translucent.
  • Pour in the beef stock and increase the heat to high. Let it reduce by half. Strain out the shallot and garlic, returning the reduced stock to the pan.
  • Add butter, whiskey, cream, and crushed peppercorns to the saucepan. Cook for 3 minutes, whisking continuously until smooth and slightly thickened. Season the sauce with salt and pepper to taste.

Serve:

  • Spoon the creamy whiskey peppercorn sauce over the rested steaks.

Notes

  • Steak Resting: Resting the steak is crucial as it allows the juices to redistribute, ensuring a moist and flavorful steak.
  • Steak Doneness Guide: Use a meat thermometer to achieve perfect doneness: 130-135°F for medium-rare; 135-145°F for medium; 145-155°F for medium-well.
  • Whiskey Selection: Opt for a smoother whiskey in the sauce to balance the flavors.
  • Peppercorn Texture: Crush peppercorns lightly for a balanced texture. If you prefer a smoother sauce, you can grind them finer.
  • Sauce Consistency: Adjust the thickness by simmering longer or adding a bit more cream or stock.
