Slice the zucchini then sprinkle generously with sea salt. Place your salted zucchini on a paper towel for 30 minutes. Once 30 minutes is up, wring the zucchini noodles with a paper towel one last time to extract any moisture.

Heat 1 tablespoon of butter or fat of choice in a large skillet over medium-high heat. Crumble and brown Italian sausage. Remove from heat and let cool.

Preheat oven to 375°F and coat a 9×9 baking dish with cooking spray or butter.

Add ricotta cheese, 1 cup of mozzarella cheese, 2 tablespoons of parmesan cheese, 1 egg, coconut flour, salt, garlic, garlic powder, and pepper to a small bowl and mix until smooth. Set aside. Add Italian seasoning and red pepper flakes to a jar of marinara, stir well. Set aside.

Add a layer of sliced zucchini to the bottom of the greased dish. Spread ¼ cup of cheese mixture over zucchini, prinkle with ¼ of the Italian sausage and then add a layer of sauce. Repeat process 3 - 4 times until ingredients are all gone, ending with a layer of sauce. Add remaining mozzarella cheese and sprinkle with remaining parmesan cheese.

Cover with foil and bake for 30 minutes. Remove foil and bake for an additional 15 minutes until golden brown.

Remove from oven and let sit for 5 - 10 minutes before serving. Sprinkle with fresh basil if desired.
