Pre-heat the oven to 180C/350F/gas mark 4

Butter a shallow oval baking dish quite generously, then cover the base with half the grated cheese.

Now carefully break 6 eggs onto the cheese, season well with salt and freshly-milled black pepper, then sprinkle the rest of the cheese over the eggs, covering them completely.

Dot with a few flecks of butter here and there, then bake in the centre of the oven for 15 minutes, by which time the cheese will be melted and bubbling, and the eggs just set.
