Cheese and onion pie is a savoury dish,[1] the basis of which is an outer layer of savoury pastry filled with a mixture of cheese, onion, herbs and sometimes potato. Many recipes contain Lancashire cheese, indicating parentage of North West England.[2]
History
This was a food traditionally popular with the working classes of Northern England, due to a combination of relatively cheap ingredients which provided sustenance to workers, particularly in the mining, steel, and manufacturing industries. Today there are artisan versions of the dish available,[3] however potato is often used to bulk out cheaper mass-produced pies, it's traditionally popular in Rochdale.
