Prep the eggplant: Slice eggplants into 1/2-inch rounds.
Lay on a sheet pan and sprinkle lightly with salt on both sides. Let sit 20–30 minutes to draw out moisture.
Pat dry: Dab both sides of each slice with paper towels to remove excess moisture and salt. This helps crisping.
Set up dredging stations: In one shallow bowl, whisk the eggs with a pinch of salt and pepper.
In a second bowl, mix Parmesan, almond flour, garlic powder, onion powder, smoked paprika, Italian seasoning, and a few grinds of pepper.
Coat the slices: Dip each eggplant slice in egg, let excess drip, then press into the Parmesan-almond mixture. Coat both sides well and tap off loose crumbs.
Choose your cooking method: Oven: Preheat to 425°F (220°C). Line a baking sheet with parchment and brush or spray with oil.
Arrange slices in a single layer, drizzle or spritz lightly with oil. Bake 18–22 minutes, flipping halfway, until deep golden and crisp.
Air fryer: Preheat to 390°F (200°C). Spray basket, add slices in a single layer, oil lightly, and cook 10–12 minutes, flipping at 6–7 minutes.
Stovetop: Heat 2–3 tablespoons avocado or olive oil in a large skillet over medium to medium-high.
Cook slices 3–4 minutes per side until golden and crisp. Work in batches and add oil as needed.
Finish and serve: Sprinkle with extra Parmesan, chopped basil, or a squeeze of lemon. For a heartier option, spoon on warm sugar-free marinara and a little melted mozzarella.
