  • butter 40g
  • plain flour 20g
  • whole milk 350ml
  • shallot 1 long, finely chopped
  • white wine 100ml
  • tarragon a handful of leaves
  • Dijon mustard 1 tsp
  • parmesan 45g, finely grated, plus a little extra
  • smoked paprika ½ tsp, plus a sprinkle
  • cooked lobster 1 large
  • flat-leaf parsley a handful, chopped
  • lemon wedges to serve


  • Step 1

    Melt 20g of the butter in a pan. Once foaming, mix in the flour and cook for a few minutes. Gradually add the milk a splash at a time, whisking throughout, only adding more once it is fully incorporated. Season and simmer for 5 minutes, then remove from the heat.

  • Step 2

    Melt the remaining butter in a small frying pan and gently cook the shallot for 5 minutes until softened. Add the white wine and bubble for a few minutes before adding the tarragon, dijon, parmesan and paprika. Stir this into the white sauce you made and season.

  • Step 3

    Use a sharp knife to cut the lobster in half, splitting the head and tail down the middle. Use a teaspoon to remove all of the tail meat, and bash the claw to remove that meat too. Roughly chop the meat and mix it into the sauce.

  • Step 4

    Heat the grill to high. Put the empty lobster shells onto a baking tray and spoon the lobster meat back into the shell. Sprinkle over a little more parmesan and a pinch more paprika, and bubble under the grill for 4-5 minutes or until golden.

  • Step 5

    Sprinkle with parsley and serve with a green salad, lemon wedges and crusty bread.
