In a large pot over medium heat, warm the olive oil. Sauté the onion, stirring occasionally, until tender, about 7 minutes. Add garlic and tomato paste; cook until fragrant, around 1 minute. Stir in crushed tomatoes, basil, and oregano. Season with salt and pepper.

Fill one of the tomato cans halfway with water, swirl to release any residual tomatoes, and add to the pot. Bring to a boil, then reduce heat and simmer, stirring occasionally, until slightly reduced and flavors meld, about 20 minutes. Set aside.

Line a large baking sheet with paper towels. Generously salt the eggplant slices on both sides and arrange in a single layer. Cover with more paper towels and weigh down with a heavy pan. Let sit for 45 minutes to release excess moisture.

Working in batches, dredge each eggplant slice in seasoned flour, dip into egg mixture, then coat thoroughly in panko-Parmesan mixture. Place breaded slices onto the prepared wire rack.

Pour vegetable oil into a large skillet to a depth of 0.5 cm. Heat over medium until shimmering. Fry eggplant in single layers until deep golden brown, about 2–3 minutes per side. Transfer to a clean wire rack and blot with paper towels. Repeat with all slices.

Spread a thin layer of marinara sauce on the base of a 33 x 23 cm baking dish. Arrange one-quarter of the fried eggplant in a single layer. Spoon over one-quarter of remaining sauce, then sprinkle with one-quarter of mozzarella and one-quarter of the leftover Parmesan. Repeat the layering process three more times.
