I would be afraid the raw slices would continue to purge themselves during thawing if you froze them. I would make the entire dish and freeze that. If you want to try something different, here's my recipe for Mulignan a la Sicilian. Just be careful who you say that to because in Sicilian it mean eggplant but in modern day Italian it is a racial epithet.
Mulignan a la Sicilian
Ingredients:
- 2 medium sized eggplants
- Kosher salt
- ½ lb ground beef
- ¼ lb ground pork
- ¼ lb ground veal
- 1 quart of homemade tomato sauce (no jarred or canned sauce, please)
- 1½ cups of Ricotta Cheese
- 1½ cups of grated Parmesan cheese
- 2 cups of shredded mozzarella cheese, divided
- 1 egg
- Light olive oil
Instructions:
Preheatoven to 375F. Lightly cover the bottom of a 13-x 9-inch baking dish (you can use ramekins to make individual servings) with tomato sauce.
Slicethe eggplant about ⅛-inch thick. Place the slices on racks withpaper towels underneath. Sprinkle both sides liberally with koshersalt and let stand fifteen minutes. Rinse thoroughly under cold running water, place on dry paper towels and pat dry.
While the eggplant is purging, combine the beef, pork and veal and brown them in light olive oil. Mix the ground meat with enough of your sauce to create a thick "sloppy joe" consistency, heat through, and set aside to cool.
Mix the three cheeses and the egg together in a large bowl, reserving ½cup of the mozzarella cheese.
In a non-stick skillet, lightly brown the eggplant slices in olive oil on both sides. The eggplant will really soak up the oil, so use itsparingly.
As they finish browning, organize the slices into sets of three of approximately the same diameter. Place one slice from each set of three in a single layer on the bottom of the baking dish. Divide ½ of the meat mixture and ½ of the cheese mixture evenly among theeggplant slices. Add a second eggplant slice from each set and evenly divide the remaining meat mixture, and the remaining cheese mixture among the second eggplant slices. Add the remaining eggplant slices, pour some of the tomato sauce over the eggplant slices, and cover them with the reserved ½ cup of mozzarella. Cover the baking dish with aluminum foil.
Bake at 375F for 45 minutes, remove the foil, and bake for an additional 15 minutes, until the mozzarella is brown and bubbly. Let stand for 15 to 30 minutes. Serve with the remaining tomato sauce.
