If you have leftover chocolate lasagna you can wrap your casserole dish in plastic wrap or transfer to an airtight container. Your chocolate lasagna will be good for 1-2 days.

Can I make this ahead of time and freeze it?

Yes, make this chocolate lasagna recipe ahead of time and freeze it for later. Assemble as directed in a disposable 7×11 pan. Cover and wrap in plastic wrap or foil to prevent freezer burn. You can keep your chocolate lasagna frozen for up to 2 months. Thaw in the refrigerator before serving.
