Step-by-step method
- Let cooked lasagne cool promptly; divide a large tray into meal-sized portions where useful.
- Transfer portions to airtight freezer-safe containers, or use a freezer-safe dish for a whole unbaked lasagne.
- Wrap dishes tightly and press excess air from bags or containers.
- Label each portion with the date and whether it is cooked or uncooked.
- Freeze flat or level where possible so portions are easier to stack.
- Thaw in the fridge when practical, then bake or reheat until the middle is piping hot throughout; reheat cooked portions only once.
Can you freeze lasagne before cooking?
Yes. Assemble lasagne in a freezer-safe dish, wrap it tightly and freeze it before baking. Defrost it in the fridge where practical, then bake until hot in the centre.
Can you freeze leftover lasagne?
Yes. Cool leftovers promptly, freeze them in airtight portions and reheat until piping hot. Small portions are easier to cool and reheat evenly.
Can you cook lasagne from frozen?
You can, but it takes longer and needs to heat right through. Cover it at first to prevent the top browning too quickly, then check that the centre is piping hot before serving.
