Preheat your oven to 400°F and line a baking sheet with parchment paper.
Pound the chicken breast to an even half-inch thickness to ensure uniform cooking.
In a shallow bowl, whisk together the grated parmesan, almond flour, garlic powder, sea salt, and black pepper.
Dredge the chicken breast in the parmesan mixture, pressing firmly so the coating adheres well to both sides.
Heat the olive oil in a non-stick skillet over medium-high heat and sear the chicken for 2 minutes per side until a golden crust forms.
Transfer the chicken to the prepared baking sheet and bake for 8 to 10 minutes or until the internal temperature reaches 165°F.
While the chicken bakes, use a spiralizer or vegetable peeler to create zucchini ribbons.
Sauté the zucchini ribbons in the same skillet used for the chicken for 2-3 minutes until tender-crisp.
In a small saucepan, warm the marinara sauce over low heat and stir in the red pepper flakes for a zesty kick.
Spread the marinara over the zucchini ribbons and top with the sliced crispy parmesan chicken.
