Follow Jackie Cook's advice, Bon Appetit!
Any frozen lasagna, homemade or store bought will thaw in about 2-3 hours, longer if kept in the fridge to thaw You can check it by sticking a knife into it or a skewer. If not completely thawed cook a little longer. You can also defrost in a microwave.
6 or so hours should do... Or just toss it in the oven frozen. It will be a little more runny but still really good
I have not bought the frozen lasagna so have no idea.
