Can lasagne be made 2 days ahead of time and sit in a throw away foil pan?

Yes, lasagne can be made two days ahead of time and stored in a throwaway foil pan. After assembling, cover it tightly with foil and refrigerate to keep it fresh. When ready to bake, you may need to adjust the cooking time as it will be cold from the fridge. Ensure it reaches an internal temperature of 165°F (74°C) before serving.
