01 - Remove beef tenderloin steaks from the refrigerator 30 minutes before cooking to temper. Pat dry with paper towels and season both sides generously with salt and pepper.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Sear steaks for 3–4 minutes per side for medium-rare doneness. Transfer to a plate, tent loosely with aluminum foil, and let rest.
03 - Reduce heat to medium. Add butter and minced shallots to the same skillet; sauté for 2 minutes until softened and translucent.
04 - Stir in minced garlic and drained peppercorns. Cook for 1 minute, stirring constantly to prevent burning.
05 - Remove skillet from heat and carefully add brandy. Return to medium heat and simmer, scraping up browned bits from the bottom, until reduced by half (approximately 2 minutes).
06 - Pour in heavy cream, Dijon mustard, and Worcestershire sauce. Simmer gently for 3–5 minutes, stirring occasionally, until sauce thickens and coats the back of a spoon. Season with salt to taste.
07 - Return rested steaks to the pan, spooning the warm sauce over the meat. Heat through for 1 minute. Serve immediately, garnished with additional peppercorns if desired.
