Trim both ends off the 2 medium eggplants and cut them into 9 rounds about 1-inch thick. Sprinkle the sliced eggplant evenly on both sides with ½ teaspoon salt. Let them sit for about 45 minutes. This coaxes the excess water out of the eggplant, which helps the breading crisp.
After resting for 45 minutes, use paper towels and the palms of your hands to press out as much water as you can from the eggplant slices.
Drizzle the eggplant with 3 tablespoons olive oil and keep flipping the slices over until the eggplant has absorbed all the oil.
Prepare a baking sheet with a wire rack inside. Preheat the oven to 375 degrees F.
Prepare 3 small bowls. Add the ¼ cup flour to one bowl. Add the 1 large egg to the second and beat until uniform. Add the ½ cup panko and grated 25 grams Parmesan cheese to the third bowl and stir to combine.
Dust the eggplant slices in flour and pat off any extra flour with your hands so that each slice has a thin even coat of flour without any clumps.
Dip the floured eggplant in the egg mixture, coating every surface and then transfer the eggplant to the bowl with the breadcrumbs.
Shake the bowl, using a tossing motion to coat the pieces evenly with bread crumbs, pressing down on them to ensure you get a nice even coating.
Place the breaded eggplant onto the wire rack and then bake until the eggplant is tender when poked with a toothpick and the breading is light brown (about 30-40 minutes).
While the eggplant bakes, make the sauce by adding the 1 tablespoon olive oil, ½ small onion and 7 grams garlic to a pan and saute over medium-high heat until the onions are tender and are starting to brown.
Add the 90 grams ground beef and sauté, breaking up the chunks until the meat is cooked.
Add the 2 tablespoons red wine and let it boil until most of the liquid is gone.
Add the 400 grams whole stewed tomatoes, ⅓ cup water, ¾ teaspoon salt, ½ teaspoon dried oregano and ¼ teaspoon ground black pepper, breaking up the tomatoes with a spatula.
Turn down the heat to maintain a gentle simmer and cook the sauce for 10 minutes.
When the eggplant is done, remove it from the oven and turn the heat up to 500 degrees F (260 C).
Pour the sauce into a 10-inch square baking dish. Lay the oven-fried eggplant on top of the sauce.
Cover the eggplant with 100 grams Mozzarella cheese and the remaining 12 grams Parmesan cheese.
Bake the eggplant parmesan until the cheese is golden brown and crusty (about 10-15 minutes).
