How long will leftover Gnocchi Gratin keep for in the fridge?
Leftovers should keep for up to 3 days in the fridge, though the breadcrumb topping will not be as crisp and the gnocchi will absorb some of the sauce and become softer. It is easiest to reheat this type of leftover in a microwave, as reheating in the oven could make it a little too dry. You could reheat leftovers in a saucepan over a medium heat until piping hot, adding a splash of extra milk if necessary and stirring occasionally. However, this would cause the breadcrumbs to be mixed into the gnocchi and also the soft gnocchi could break up a little when stirred.
