Mary Berry Beef Stroganoff is a British-style take on the traditional dish, made with lean beef cooked quickly, mushrooms softened in butter, and a creamy sauce finished with a touch of mustard and crème fraîche or sour cream. The key is speed and balance—keeping the beef tender while allowing the sauce to stay smooth and lightly tangy.
500g beef sirloin or rump steak, thinly sliced
2 tablespoons olive oil or butter
1 medium onion, finely sliced
250g mushrooms, sliced
1 tablespoon plain flour
150ml beef stock
1 tablespoon Dijon mustard
150ml crème fraîche or sour cream
Salt and black pepper, to taste
Fresh parsley, chopped, to finish
Prepare the beef – Slice the beef thinly against the grain and season lightly with salt and pepper.
Sear quickly – Heat oil or butter in a hot pan and fry the beef in batches for 30–60 seconds until just browned. Remove and set aside.
Cook the vegetables – In the same pan, add onion and cook gently until soft, then add mushrooms and cook until lightly golden.
Add flour – Sprinkle over the flour and stir well to coat the mushrooms and onions.
Build the sauce – Gradually add beef stock, stirring until smooth and slightly thickened.
Add mustard – Stir in Dijon mustard for gentle sharpness.
Finish with cream – Lower the heat and stir in crème fraîche or sour cream.
Return the beef – Add the beef back to the pan and heat gently for 2–3 minutes.
Season and serve – Taste, adjust seasoning, sprinkle with parsley, and serve immediately.
