Freeze the unbaked casserole in a disposable foil pan, or line your baking dish with foil. Use the foil to lift the frozen casserole from the dish, then wrap tightly and freeze. Pop the frozen casserole back into the original dish to bake.
Toss together a simple salad of mixed greens, sliced plum (Roma) tomatoes and your favorite dressing.
Add a label with the baking instructions and give this lasagna casserole as a gift.
