Sour Cream Swiss Steak is a classic comfort food dish made with tenderized beef steak, smothered in a rich and creamy sour cream sauce. The steak is first seared to lock in the flavors, then simmered in a flavorful tomato-based sauce until it becomes tender and juicy. The addition of sour cream adds a tangy and creamy element to the dish, making it even more delicious. Serve this hearty and comforting meal with mashed potatoes or rice for a satisfying dinner.
