This recipe guides you in preparing a classic Beef Stroganoff. It features tender beef stew meat, mushrooms, and onions simmered in a rich, savory sauce with beef stock, soy sauce, and mustard. Finished with a creamy blend of sour cream and cream cheese, it's served over buttered extra-wide egg noodles and garnished with fresh parsley.
Browning the beef in batches is crucial; overcrowding the pan will steam the meat instead of searing it, preventing the development of deep, rich flavor. Ensure you thoroughly scrape up the 'fond' (brown bits) from the bottom of the pot after browning the meat and sautéing the aromatics – these bits are concentrated flavor. The long simmering time is essential for transforming the stew meat into tender, melt-in-your-mouth perfection. When adding the sour cream and cream cheese, ensure they are softened and incorporate them off the heat or at a very gentle simmer to prevent curdling, yielding a smooth, luxurious sauce. Always taste and adjust seasoning with salt and pepper at the very end.
