Wash the eggplants thoroughly and cut off the tops. Slice them into half-inch thick rounds.
Salt and drain the eggplant
Sprinkled salt on eggplant slices, let sit 30 mins. Rinse off the salt and pat dry with paper towels.
Breading process
Dip the eggplant slices in beaten eggs, then coat in a mixture of almond flour, grated parmesan cheese, and Italian seasoning.
Bake the breaded eggplant
Preheat the oven to 400°F. Place breaded eggplant on a parchment-lined sheet. Bake for 20–25 minutes until golden and crispy, flipping halfway through.
Layer the casserole
In a baking dish, spread marinara sauce, add a layer of baked eggplant, then mozzarella cheese. Repeat layers until ingredients are used, finishing with cheese.
Bake the assembled casserole
Bake at 375°F (190°C) for 30 minutes until cheese is melted and bubbly.
Rest before serving
Let the dish chill out a bit before serving so the flavors can mix together.
