Beef Stroganoff

A Russian classic of thinly sliced beef and mushrooms in a sour cream sauce, served over egg noodles or rice. Searing the beef fast keeps it tender — a comforting one-pan dish.

Ingredients

3servings
  • Beef (sirloin/tenderloin) · thinly sliced400 g
  • Mushrooms · sliced200 g
  • Onion · sliced1
  • Butter2 tbsp
  • Cooking oil1 tbsp
  • Flour · to thicken1 tbsp

  • Sour cream120 ml
  • Dijon mustard · optional1 tsp
  • Salt & pepper1 to taste
  • Parsley1 to garnish
  • To serve
  • Egg noodles or rice1 to serve

Steps

  1. Slice the beef thinly against the grain and season with salt and pepper.

    ⏲ 3 min
  2. Heat oil in a pan over high heat and quickly sear the beef in two batches, just on the surface, then remove (overcooking makes it tough).

    ⏲ 3 min
  3. Melt the butter in the same pan, cook the onion, then add the mushrooms and brown them.

    ⏲ 5 min
  4. Stir in the flour and cook 1 minute, then whisk in the stock gradually until thickened.

    ⏲ 3 min
  5. Lower the heat and stir in the sour cream and mustard (low heat so it doesn't split). Season with salt and pepper.

    ⏲ 2 min
  6. Return the beef and warm through 1–2 minutes. Serve over egg noodles or rice, with parsley.

    ⏲ 2 min

Variations

  • More mushrooms: Mix in shiitake or oyster mushrooms for depth.
  • Vegetarian stroganoff: Use all mushrooms instead of beef.
  • Brandy/wine: Deglaze with a splash of brandy or white wine.
  • Sides: Great over egg noodles, rice, or mashed potato.

Tips

  • Sear the beef fast over high heat and add it back at the end so it stays tender.
  • Add the sour cream off high heat so it doesn't curdle.
  • Brown the mushrooms well for umami.
  • Whisk in the stock gradually for a smooth sauce.
  • A spoon of mustard sharpens the flavor.
More detail and the reasons why (4)
  • Sour cream falls between cream and yoghurt. Cream is ruled by its fat — 35% and above survives boiling, 30% and below splits easily — and yoghurt is the most fragile dairy of all because it is already acidic (dairy and heat). Sour cream is both at once: acidic like yoghurt, but around 20% fat, and that fat coating the protein is the margin the yoghurt in rogan josh does not have. Margin, not immunity: boil it and it splits.
  • The flour is doing two jobs, and the second one is why this works at all. A tablespoon cooked in the pan and let down with stock is a roux (thickening) — and swollen starch also physically gets between the casein and stops it knitting, which is the same fix used for a clumping cheese sauce. Chicken paprikash also tempers the sour cream and does not boil it; the flour already in both pans is half of why either survives at all. Dovga is that protection taken to the limit — egg and two spoons of flour beaten into a litre of yoghurt, which is then boiled outright.
  • The beef stays tender because of how little time it spends hot. Thin slices cut against the grain are through in under a minute, and they go back in only to warm at the end. The sear is there for the fond, not to seal anything in — and it is done in two batches (browning), because a crowded pan steams the beef grey and leaves nothing to deglaze.
  • The mustard is an emulsifier too. It is a weak but genuinely effective one (why sauces split), so the teaspoon is doing more than sharpening: it helps hold the fat from the butter and the sour cream in the sauce instead of letting it pool.
