Ingredients
For the Seafood Cassolette
225g raw king prawns, peeled and deveined
225g sea scallops, cleaned and patted dry
225g firm white fish (such as cod or haddock), cut into generous pieces
225g fresh mussels, scrubbed and debearded
2 shallots, finely minced
4 garlic cloves, finely minced
60g unsalted butter
2 tablespoons plain flour
120ml dry white wine
120ml seafood stock or reserved mussel liquour
240ml double cream
½ teaspoon Dijon mustard (optional, for gentle depth)
1 teaspoon fresh thyme leaves, finely chopped
2 tablespoons fresh parsley, finely chopped
Sea salt and freshly ground black pepper, to taste
For the Golden Gratin Topping
50g fresh breadcrumbs
25g Gruyère cheese, finely grated
2 tablespoons melted butter
Method
Begin by gently steaming the mussels in a splash of white wine with the garlic and thyme until they open. Discard any that remain closed, then strain and reserve the fragrant cooking liquour.
In a wide pan, melt the butter over a soft heat. Add the shallots and cook slowly until softened and translucent. Stir in the flour and cook briefly to form a smooth, pale roux.
Gradually pour in the white wine, followed by the seafood stock and cream, stirring continuously until the sauce becomes silky and lightly thickened. Allow it to simmer gently.
Stir through the Dijon mustard, thyme, and a seasoning of sea salt and freshly ground black pepper. Add the prawns, scallops, and white fish, allowing them to poach delicately in the sauce until just tender.
Fold in the mussels and finish with fresh parsley, ensuring everything is evenly coated in the velvety sauce. Spoon the mixture into individual ramekins or a single baking dish.
In a small bowl, combine the breadcrumbs, Gruyère, and melted butter. Scatter the mixture generously over the surface.
Bake in a preheated oven at 200°C for 12–15 minutes, until the topping is golden and crisp. For a deeper colour, finish briefly under the grill.
Serve immediately, while the filling is bubbling and the crust delicately crisp.
