Slice eggplant 1/2 inch thickness. Place sliced eggplant on baking sheet lined with paper towel and sprinkle each side with salt. Let it sit for 20 minutes. Brush off the salt.
Meanwhile, using a small skillet, over medium heat, add panko bread crumbs and stir until crispy about 2-3 minutes. Remove and once cooled, mix in Parmesan cheese. Set aside until ready to assemble. Warm the marinara sauce in a sauce pot.
