Ingredients

  • 1 x 300 g fillet steak
  • 2 tbsp oil
  • 1 large handfuls field mushrooms
  • knob of butter
  • 1 tbsp crème fraîche
  • 1 egg yolk
  • 1 tbsp chopped chives
  • 1 tsp wholegrain mustard
  • 1 handfuls grated parmesan
  • rocket salad, to serve

Method

1. Preheat the grill to high.

2. Season the fillet steak with salt and pepper. Heat a frying pan with the oil until smoking, then sear the steak on all sides. Fry for 2 minutes on each side (for medium rare), or until cooked to your liking. Finish with the knob of butter.

3. Add the mushrooms to the pan and lightly fry until cooked through. Remove the pan from the heat to allow the steak to rest, and spoon the mushrooms into a small bowl and set aside.

4. In a bowl, mix together the crème fraîche, egg yolk, chopped chives, grain mustard and grated parmesan until well combined. Fold in the mushrooms, then spoon the mixture on top of the fillet steak and cook under the grill for 5 minutes, or until the topping is golden and bubbling.

5. Serve with a rocket salad on the side.
