Beef stroganoff

1. Heat the olive oil in a non-stick frying pan then add the sliced onion and cook on a medium heat until completely softened, so around 15 mins, adding a little splash of water if they start to stick at all. Crush in the garlic and cook for a 2-3 mins further, then add the butter. Once the butter is foaming a little, add the mushrooms and cook for around 5 mins until completely softened. Season everything well, then tip onto a plate.

2. Tip the flour into a bowl with a big pinch of salt and pepper, then toss the steak in the seasoned flour. Add the steak pieces to the pan, splashing in a little oil if the pan looks particularly dry, and fry for 3-4 mins, until well coloured. Tip the onions and mushrooms back into the pan. Whisk the crème fraîche, mustard and beef stock together, then pour into the pan. Cook over a medium heat for around 5 mins. Scatter with parsley, then serve with pappardelle or rice.

Cooking notes

When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
