Preheat your oven to 400°F (205°C).
Begin by slicing the eggplant into rounds and set aside.
In a shallow bowl, mix together almond flour, Italian seasoning, garlic powder, salt, and pepper.
In another bowl, whisk the eggs and almond milk until well combined.
Dip each eggplant slice into the egg mixture, then dredge in the almond flour mixture, ensuring each slice is well-coated.
Heat a generous amount of olive oil in a large skillet over medium heat. Fry the eggplant slices in batches until golden brown on each side, about 2-3 minutes per side. Transfer to a paper towel-lined plate to drain excess oil.
In a baking dish, spread a thin layer of marinara sauce.
Layer the fried eggplant slices over the sauce. Spoon more marinara on each slice and sprinkle with mozzarella and Parmesan cheese.
Repeat the layering process until all ingredients are used, finishing with cheese on top.
Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden.
Garnish with fresh basil before serving.
