Prep the oven and pan: Heat the oven to 425°F (220°C).
Lightly oil a 9x13-inch baking dish or line a sheet pan with parchment for easier cleanup.
Prep the chicken: Pat the chicken dry. If using whole breasts, slice them in half horizontally to make cutlets. Season both sides with a pinch of salt and pepper.
Set up the coating: In one shallow bowl, beat the eggs.
In another, mix the almond flour, Parmesan, Italian seasoning, garlic powder, onion powder, salt, and pepper.
Coat the chicken: Dip each cutlet into the egg, let the excess drip off, then press it into the almond flour mixture until well coated on both sides.
Quick sear for texture: Heat the olive oil in a large skillet over medium-high. Sear the coated chicken 1–2 minutes per side until lightly golden. You’re not cooking through—just adding color and crunch.
Layer it up: Spread 1/2 cup marinara in the baking dish.
Arrange the seared chicken on top. Spoon the remaining marinara over the cutlets, then sprinkle with mozzarella and an extra dusting of Parmesan.
Bake: Bake for 12–15 minutes, until the chicken reaches 165°F (74°C) in the center and the cheese is melted and bubbling.
Broil for color: Switch to broil for 1–3 minutes to brown the top. Watch closely to avoid burning.
Finish and serve: Let it rest 5 minutes.
Sprinkle with fresh basil and crushed red pepper if you like. Serve with zucchini noodles, roasted broccoli, or a crisp salad.
