This is a budget-friendly supper dish using tinned tuna and Cheddar cheese and a creamy bechamel sauce.
This recipe calls for dry lasagne sheets that need pre-cooking, however the no-cook sheets have found their way onto the shelves and in many ways made the original sheets redundant. It comes down to personal preference for texture and consistency. Fresh lasagne sheets are now also available.
This lasagne freezes well. To reheat, thaw the lasagne and heat in the oven for 1 hour at 190 C / Gas 5.
