Beef Stroganoff is a traditional Russian dish consisting of sautéed pieces of beef served in a creamy mushroom sauce, typically with beef broth, mustard, and smetana (sour cream). The dish is named after the influential Stroganov family of imperial Russia. The sauce used in beef stroganoff may vary, but it is typically made with a base of beef stock or broth, mushrooms, and onions, with a finishing touch of smetana. The dish is often served over egg noodles, rice, or potatoes. In Hebrew, it is known as ביף סטרוגנוף. In French, it is called bœuf Stroganoff, while in German, it is referred to as Beef Stroganoff or Stroganoff. The dish gained international popularity in the mid-20th century and has since become a staple in many countries, with numerous regional variations. Despite its Russian origins, the exact history of the dish is somewhat unclear, with some sources suggesting it was created by a French chef employed by the Stroganov family, while others attribute its invention to Count Alexander Grigoryevich Stroganov.
