Preparation

• 帕特牛排干with a paper towel and season both sides lightly with salt. Coat both sides with the peppercorns, pressing so they adhere. Heat the oil in a 12-inch heavy-duty skillet over medium-high heat until shimmering hot. Add the steaks and cook to your desired doneness (2 to 3 minutes per side for medium rare). Transfer the steaks to a cutting board and tent them with foil. Pour off and discard any fat left in the pan, but not the brown bits.
• Reduce the heat to medium and add the butter to the skillet. When melted, add the shallot and cook until softened, about 1 minute. Remove the skillet from the heat and carefully add the Cognac. Return the skillet to medium heat and cook, whisking, until the Cognac reduces to a glaze, 1 to 2 minutes. Whisk in the cream and simmer until slightly thickened, 1 to 2 minutes. Stir in the parsley and season to taste with salt.
• Transfer the steaks to dinner plates and top with the sauce.
