What do I do with this pre-cooked frozen lasagna?

Asked by LeavesNoTrace (5674

My MIL and I made lasagna on Christmas Eve, and she sent me home with an extra one. It’s already baked, and has been sitting in my freezer in a nice Corningware pan.

I’d like to serve it to our friends tomorrow for NYE. It’s quite large, and I’m not sure if I should thaw it in the fridge for 24 hours first or put it in the oven while it preheats and cook it for an hour? (I don’t want to damage her Corningware baking pan, obviously.)

Any pointers? Thanks in advance.

Thaw it in the fridge overnight; then heat it for about 45 minutes or so at something like 325 F. Poke it to see if it is hot all the way through.

Thanks @janbb! Should I put it in the oven while it preheats or pop it in when it reaches 325?

Wait until it reaches 325. Sometimes the broiler coils are used for preheating and that could put too much heat on the lasagna. If it is not heating through fast enough, you could turn the oven up to 350 toward the end.

Great advice, @janbb. Many thanks. I may also take the foil off at the end and add some shredded parm to get nice and bubbly brown. :D
