Skirt Steak Sauerbraten is a flavorful and tender German dish made with marinated skirt steak. The steak is marinated in a mixture of vinegar, spices, and aromatics for several days, which helps to tenderize the meat and infuse it with rich flavors. After marinating, the steak is slow-cooked until it becomes melt-in-your-mouth tender. The dish is traditionally served with a tangy and sweet gravy made from the marinade, along with sides like potato dumplings or spaetzle.
