Preheat the oven to 350°F. Slice the eggplant into 1/4-inch wheels and sweat them in a skillet over medium heat for 2-3 minutes on each side. Remove from the pan and pat dry with a paper towel.
Mix the breadcrumbs with the thyme, oregano, salt, and pepper in a bowl. Use a fork to whisk the eggs in a separate bowl. Then, coat the eggplant slices in the egg mixture and then place them in the crumb bowl.
Heat a pan and add the oil, then fry the breaded eggplant until golden brown, about 2-3 minutes per side.
In a large, oven-safe dish, pour a generous amount of marinara sauce. Then, layer on the eggplant, mozzarella, and Parmesan. Continue to build up the dish by repeating the layers at least 3 times. Pop into the heated oven and bake for 20-30 minutes. Garnish with fresh basil and serve.
