Pierce flanks steak throughout using a large fork, flip, and repeat. Place steak in a plastic zip-top bag and pour in marinade to cover. Marinate in the refrigerator, 8 hours to overnight. Combine sour cream, green onions, horseradish, salt, and pepper in a bowl. Cover and refrigerate sauce until ready to use, up to 24 hours. Preheat an outdoor grill for high heat and lightly oil the grate. Drain steak and pour marinade into a small saucepan. Bring marinade to a boil over high heat and boil for 1 minute. Remove from heat. Season steak with pepper. Cook steak on the preheated grill to desired doneness, basting occasionally with marinade, about 5 minutes per side for medium doneness. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Transfer steak to a plate and let rest for 15 minutes. Cut across the grain into thin diagonal slices. Serve hot or at room temperature with horseradish sauce. Editor's Note: Nutrition data for this recipe includes the full amount of marinade ingredients.
