Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Pound the chicken breast to an even thickness and season both sides with sea salt and black pepper.
In a shallow bowl, whisk the egg until smooth; in a second bowl, combine the almond flour, grated parmesan, oregano, and garlic powder.
Dip the chicken into the egg wash, then press firmly into the almond flour mixture until the breast is fully and evenly coated.
Heat the olive oil in a skillet over medium-high heat and sear the chicken for 2 minutes per side until the crust is golden brown.
Place the seared chicken on the baking sheet, top with marinara sauce and shredded mozzarella, and bake for 10-12 minutes until the cheese is bubbly.
While the chicken bakes, lightly sauté the zucchini noodles in the same skillet for 2-3 minutes until just tender.
Plate the zucchini noodles, top with the crispy chicken parmesan, and garnish with fresh basil before serving.
