1. Preheat the oven to 350 degrees F. Spray a 9x13 baking dish with cooking spray. Set aside. Cook the pasta according to instructions for al dente, about 7 minutes. Drain and set aside.

2. In a medium bowl, combine the ricotta, parmesan, and egg. Stir until smooth. Add the garlic, spinach, nutmeg, dried basil, crushed red pepper, and salt and pepper.

3. Put half of the pasta into the prepared baking dish and top with half of the marinara sauce. Spoon the spinach ricotta mixture on top of the sauce in an even layer. Sprinkle half of the mozzarella cheese over the mixture. Cover with the remaining pasta and the remaining sauce. Top with the remaining mozzarella cheese.

6. Cover with foil and bake for 25 minutes. Remove foil and bake for an additional 5-10 minutes or until the mozzarella is melted and the edges are lightly browned. Serve warm.

Note-you can prepare this dish one day ahead of time. Cover the pan with foil and place in the fridge until you are ready to cook. You can also freeze the leftovers. Place cooked pasta in freezer containers and freeze!
