Deep-fried soft-boiled egg with mushrooms, toasted brioche and herb mayonnaise

For a truly indulgent breakfast, try deep-frying the eggs and making your own tarragon and parsley mayonnaise.


For the deep-fried soft-boiled egg
  • 2 tbsp white wine vinegar
  • 5 free-range eggs
  • 110g/4oz plain flour
  • 200g/7oz fresh breadcrumbs
  • vegetable oil, for deep-frying
  • 50g/1¾oz butter
  • 1 tbsp olive oil
  • 1 banana shallot, finely chopped
  • 1 garlic clove, finely chopped
  • 300g/10½oz mixed wild mushrooms, torn into pieces if large
  • ½ loaf brioche, cut into thick slices
For the mayonnaise
  • 2 egg yolks
  • 2 tsp white wine vinegar
  • 1 tsp Dijon mustard
  • 300ml/10fl oz vegetable oil
  • 4 tbsp chopped fresh parsley
  • 2 tbsp chopped fresh tarragon
  • salt and freshly ground black pepper

Preparation method

  1. For the deep-fried egg, bring a large saucepan of water to the boil, add the vinegar and a pinch of salt. Boil 4 of the eggs for 5 minutes. Remove the eggs from the saucepan using a slotted spoon, and leave to chill in a bowl of ice-cold water.

  2. Crack the remaining egg into a bowl. Whisk with a pinch of salt and pepper.

  3. Peel the boiled eggs. Prepare a shallow plate of flour and a separate plate of breadcrumbs. Dredge the boiled eggs in the flour, then dip into the beaten egg and roll in the breadcrumbs. Set aside on a tray in the fridge until needed.

  4. Heat the oil in a deep-fat fryer to 180C/350F. Alternatively, pour the oil into a deep, heavy-based pan to a depth of 2cm/¾in and bring to the same temperature on the hob. (CAUTION: hot oil can be dangerous. Do not leave unattended.)

  5. Fry the eggs until golden-brown. Remove with a slotted spoon, drain on kitchen paper and season with salt.

  6. Heat a frying pan, add the butter and olive oil. Add the shallot and gently fry for 3 minutes, until just softened. Add the garlic and mushrooms and cook until the mushrooms have released their liquid and are tender. Season with salt and pepper.

  7. Heat a clean frying pan. Lay the brioche in the hot pan and toast each side until golden-brown.

  8. For the mayonnaise, put the egg yolks, vinegar and mustard in a food processor and blend until pale and creamy.

  9. With the motor running, pour in a steady stream of oil until the mayonnaise is thick (you may not need all the oil). Just before serving add the herbs and blend.

  10. To serve, cut a hole in the slices of brioche and sit the eggs in the holes. Dress the plate with mushrooms and mayonnaise.
