If you are looking for a recipe that transforms an inexpensive, lean cut of beef into an incredibly tender, melt-in-your-mouth dinner, this Oven-Baked 4-Ingredient Sour Cream Swiss Steak is it.
Traditional Swiss steak often relies on a heavy, tomato-based cube steak braise. This version turns that concept on its head by utilizing a rich, velvety sour cream gravy instead. As it bakes low and slow in the oven, the enzymes in the sour cream break down the tough fibers of the beef, leaving you with fork-tender steaks coated in a deeply savory, luscious pan sauce.
The 4-Ingredient Lineup
Because this recipe is incredibly streamlined, each component works double-duty to provide both moisture and intense savory flavor:
1.5 to 2 lbs Cube Steak (or Round Steak): Cube steak is ideal because it has already been mechanically tenderized (giving it those characteristic dimples), which allows the rich sauce to penetrate deep into the meat.
1 can (10.5 oz) Condensed Cream of Mushroom Soup: This serves as the flavor-packed base for your gravy, bringing an earthy richness without needing to chop fresh mushrooms or onions.
1 cup Full-Fat Sour Cream: This is the secret weapon. The mild acidity in full-fat sour cream actively tenderizes the beef during the long bake while creating a beautifully tangy, velvety sauce.
1 Packet (1 oz) Dry Onion Soup Mix: Packed with caramelized onion pieces, beef bouillon flavor, and seasonings, this single packet eliminates the need for an entire spice rack.
