Cheese and onion pie is an English comfort food dish. Although it is consumed all over the country, some sources suggest that it's a north-western tradition. The pie is typically made with a combination of shortcrust pastry, cheddar or crumbly cheeses, and cooked or fried onions.

Common, yet non-traditional additions include potatoes, crème fraîche, and a sauce made with flour, milk, and cream. It is recommended to serve the pie warm or cold, preferably accompanied by chips and a salad on the side.
