Thinly sliced potatoes are layered and baked in cream, with garlic and nutmeg folded through the sauce. It comes as a frozen side, ready to heat from chilled or frozen depending on the pack instructions, and the texture is meant to stay soft at the centre with browned edges as it cooks. In Sainsbury’s frozen range, it sits alongside other potato sides and veg dishes rather than the main meal options. The ingredient list is short and familiar, built around potato, cream, garlic and spice, so the focus is on the structure of the dish: neat slices, a creamy binder, and a gratin-style finish.
