In 10-inch skillet, melt 1 tablespoon of the butter over medium-high heat. Sprinkle steaks with 1/2 teaspoon salt and 1/4 teaspoon pepper. Cook steaks in butter 4 to 6 minutes, turning once, until deep brown. Reduce heat to low. Cover; cook 6 to 8 minutes for medium-rare to medium doneness (don't overcook; beef will continue to cook while standing). Remove beef to platter; cover to keep warm.
