Stroganoff has a wonderful reputation for feeling far more special than the effort it actually takes, and that reputation is entirely deserved.
Unlike a long, slow braise, this is a quick-cooking dish that relies on good, tender beef cooked fast over high heat, then finished in a rich, tangy sauce built from mushrooms, mustard and soured cream.
It’s genuinely one of the quickest proper dinners I make, and it always feels like more of an occasion than the actual time in the kitchen would suggest.
Why the Beef Needs to Be Cooked Fast, Not Slow
Stroganoff uses a completely different approach to cooking beef than a braise or stew does, and that’s very much intentional.
Rather than tough cuts that need hours to tenderise, stroganoff traditionally uses tender cuts like sirloin or fillet, cut into thin strips and cooked very quickly over high heat — just a minute or two, until browned on the outside but still pink and juicy within.
Cook these tender cuts for too long, and they toughen up rather than staying soft, which is the exact opposite of what happens with a braising cut over a long, slow cook. Speed, here, is what keeps the beef tender.

Ingredients for Delia Smith Beef Stroganoff
- 500g beef sirloin or fillet, cut into thin strips
- Salt and freshly ground black pepper
- 2 tbsp vegetable oil
- 1 onion, finely sliced
- 250g chestnut mushrooms, sliced
- 2 tsp Dijon mustard
- 1 tbsp brandy (optional)
- 200ml beef stock
- 150ml soured cream
- Fresh parsley, chopped, to finish
How to Make Delia Smith Beef Stroganoff — Step by Step
Step 1 — Season the Beef
Season the beef strips generously with salt and pepper.
Step 2 — Sear the Beef Quickly
Heat half the oil in a large frying pan over high heat until very hot. Sear the beef in batches for 1–2 minutes, just until browned on the outside but still pink inside. Remove and set aside.
Step 3 — Cook the Onion and Mushrooms
Add the remaining oil to the pan, then cook the onion for 3–4 minutes until softened. Add the mushrooms and cook for a further 5 minutes, until golden and any liquid they release has evaporated.
Step 4 — Add the Mustard and Brandy
Stir in the Dijon mustard, then add the brandy, if using, letting it bubble for 30 seconds.
Step 5 — Add the Stock
Pour in the beef stock and simmer for 3–4 minutes, until slightly reduced.
Step 6 — Stir in the Soured Cream
Reduce the heat to low and stir in the soured cream, mixing until you have a smooth, glossy sauce. Don’t let it boil at this stage, as it may split.
Step 7 — Return the Beef
Return the seared beef and any resting juices to the pan, stirring gently to coat in the sauce and warm through for 1–2 minutes.
Step 8 — Finish and Serve
Scatter with fresh parsley and serve immediately.
My Top Tips for the Best Delia Smith Beef Stroganoff
Use a tender cut of beef, not a stewing cut. This dish cooks quickly, so a cut like sirloin or fillet is essential — a tougher cut simply won’t have time to become tender.
Don’t overcrowd the pan when searing. Cooking the beef in batches over high heat means it browns properly rather than steaming, which happens if too much goes in at once.
Keep the heat low once the soured cream goes in. Boiling soured cream can cause it to split and turn grainy, so gently warm through rather than letting it bubble.
Cook the mushrooms until their liquid has evaporated. This concentrates their flavour and stops the finished sauce turning watery.
Add the beef back in right at the end. This keeps it tender and just warmed through, rather than overcooking it a second time in the sauce.
Serving Suggestions
Serve over rice or with buttered tagliatelle, both of which soak up the sauce beautifully. A simple green salad on the side is a nice, light accompaniment to balance the richness.
How to Store Delia Smith Beef Stroganoff
In the fridge: Store in an airtight container for up to 2 days. Reheat gently over low heat, without boiling, to avoid the sauce splitting.
At room temperature: Not suitable — cool and refrigerate promptly after cooking.
In the freezer: Not recommended — soured cream sauces can split and separate on freezing and thawing, affecting the texture significantly.

Notes
Frequently Asked Questions About Delia Smith Beef Stroganoff
Why did my sauce split or go grainy?
This almost always happens if the soured cream was allowed to boil. Keep the heat low once it’s added, and simply warm through gently rather than letting the sauce bubble.
Can I use a cheaper cut of beef?
You can, but it needs to be cooked very quickly, and tougher cuts will end up chewy rather than tender using this fast-cooking method. If you only have a tougher cut, a longer braise-style recipe would suit it better.
Can I make this without brandy?
Yes, it’s entirely optional — simply leave it out, or replace it with a splash of extra beef stock for a similar depth without the alcohol.
What can I use instead of soured cream?
Crème fraîche works well as a substitute and is slightly less likely to split, making it a good option if you’re a little nervous about the sauce.
