You can make something like eggplant parmesan that will freeze pretty well. I think you’d just get a watery mess trying to freeze the uncooked or even blanched veg.
That’s a good idea. We can buy eggplant Parmesan frozen in the stores, so I could freeze my own. I really like the crunchy breading though and then put it all together at the end. But it would at least still have the same flavors.
