Preheat oven to 375°F. Spray a 9x13-inch baking pan with nonstick spray. Set aside.
In a large skillet set over medium heat, cook the Italian sausage until completely browned. Drain any excess grease out of the pan and set aside to cool.
8 ounces Italian sausage
Whip the cream cheese in a large bowl until smooth. Add the Italian seasoning, onion powder, red pepper flakes, salt, and pepper and mix again until completely combined.
8 ounces cream cheese, 1 teaspoon Italian seasoning, 1 teaspoon onion powder, ½ teaspoon red pepper flakes, ½ teaspoon kosher salt, ½ teaspoon ground black pepper
Add ¾ cup mozzarella cheese, Parmesan, basil, and garlic to the cream cheese mixture. Stir in the cooled sausage.
1½ cups freshly shredded mozzarella cheese, ½ cup freshly grated Parmesan cheese, 10 basil leaves, 3 cloves garlic
Peel the zucchini into long strips using a vegetable peeler. Blot the zucchini “noodles” dry.
4 zucchini
Assemble the ravioli. Place 2 zucchini slices across each other to form an X then lay two more slices on top in another X to form a star shape. Add a dollop of the cream cheese sausage filling to the center of the zucchini star and fold the zucchini strips into the center. Repeat until all of the zucchini strips and filling are used up.
Spread half of the marinara sauce into the bottom of the prepared baking pan. Place the zucchini ravioli evenly on top of the sauce.
32 ounces marinara sauce
Spread the remaining marinara sauce on top of the ravioli. Sprinkle the remaining mozzarella cheese on top.
Bake for 25-30 minutes or until the cheese is fully melted on top. Serve and enjoy!
