01 - Remove beef tenderloin steaks from the refrigerator 30 minutes before cooking to temper. Pat dry and season both sides with salt and pepper.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering.
03 - Sear the steaks for 3–4 minutes per side for medium-rare. Adjust cooking time for desired doneness. Transfer to a plate, tent loosely with foil, and rest.
04 - In the same skillet, reduce heat to medium. Add butter and shallots; sauté for 2 minutes until softened.
05 - Add garlic and peppercorns; cook for 1 minute, stirring constantly.
06 - Off the heat, carefully add brandy. Return to heat and simmer, scraping up any browned bits, until reduced by half (about 2 minutes).
07 - Stir in cream, Dijon mustard, and Worcestershire sauce. Simmer gently for 3–5 minutes, stirring occasionally, until thickened. Season with salt to taste.
08 - Return steaks to the pan, spoon sauce over, and warm through for 1 minute. Serve immediately, garnished with extra peppercorns if desired.
