Recreate the steakhouse at home, with this classic French dish that pairs lean beef filet with a creamy, peppered pan sauce for a delicious meal any day of the week. Pair with your favorite wine and salad to complete the meal.
Season steaks with salt; press top of filets in 2 tablespoons cracked pepper, pressing evenly onto top of the steak.
Heat large cast-iron skillet over medium heat until hot. Place steaks, peppercorn side down, in skillet turning until seared on all sides. Add 2 tablespoons butter, garlic and thyme. Cook, spooning steaks with butter, 8 to 10 minutes for medium rare (145°F) to medium doneness (160°F). Remove steaks from pan; keep warm.
Add shallots; cook 2 minutes or until softened, stirring occasionally. Add brandy; cook 1 to 2 minutes or until alcohol burns off and browned bits attached to skillet are dissolved.
Stir in cream, demi-glace, Worcestershire sauce, mustard and remaining 1-1/2 teaspoons cracked peppercorns. Cook 3 to 5 minutes or until sauce is smooth and slightly thickened. Remove from heat and gently swirl remaining 2 tablespoons of butter into sauce. Spoon sauce over warmed steaks.
