Leaving the peel on your eggplants, slice the eggplant lengthwise or crosswise (your choice) into ¼-inch-thick slices.
Place the slices in a colander, sprinkling with sea salt as you layer in the slices. Place your colander in the sink and let the eggplant sit for 30 minutes.
Pat the eggplant dry with a clean dishtowel or paper towels (do not rinse the eggplant!). This step is important to prevent sogginess.
Preheat your oven to 400 degrees f. and line 2 large baking sheets with parchment
paper.
Prepare your prep station:
In a shallow dish whisk the almond flour with 1/4 cup of the Parmesan, all Italian seasonings, and all of your garlic powder.
In a second dish, beat the eggs with a good pinch of sea salt and pepper.
Dip your eggplant slices into the beaten eggs, then coat lightly with the almond flour mixture.
Arrange on your prepared baking sheets without overlapping and spray or spritz very lightly with cooking oil.
Bake for 20-25 minutes, or until the coating is golden and crisp. Carefully flip them over halfway through baking time.
Spread 1 cup of marinara in a baking dish. Arrange a layer of eggplant slices over the sauce. Sprinkle a thin layer of mozzarella and parmesan, then top with more marinara sauce as shown. Repeat your layers again, finishing with a final topping of mozzarella.
Bake in your preheated oven for 15-20 minutes or until bubbling and the cheese is melted and golden on top.
