In a medium saucepan over low heat, melt the butter and whisk in the flour. Cook for a few minutes, stirring constantly, until smooth and bubbly.
Gradually whisk in the cream and bring to a boil. Reduce the heat and simmer, stirring occasionally, until thickened, about 10 minutes.
Stir in the salt, pepper, paprika, and nutmeg. Remove from the heat and let cool slightly.
Whisk in the eggs and stir in the lobster meat.
Pour the filling into the prepared pie dish and sprinkle the topping evenly over it.
Bake for 25 to 30 minutes or until golden and bubbly.
Let the pie rest for 10 minutes before slicing and serving.
