Beef Shin Cottage Pie

What is it?

Rich beef shin and bone marrow sit under a layer of mashed potato in this two-person frozen cottage pie. On top, there’s a crumb made with Parmigiano and ciabatta, which gives the dish a browned, slightly crunchy finish after oven baking. Compared with more basic cottage pies in Sainsbury’s frozen range, this one leans on shin rather than minced beef and adds the cheese-and-bread topping for a different texture. It’s the kind of freezer meal that goes from oven to table in one dish, with a saucey meat base and a soft potato cap.
