Ingredients1 tbsp olive oil
1 onion
1 clove of garlic
1 tbsp butter
250g mushrooms
500g fillet steak, sliced
1 tbsp plain flour
150g crème fraîche
1 tsp English mustard
100ml beef stock
½ small pack of parsley
Prep: 10 MINS
Cook: 35 MINS
Method1)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.
