  • 2 cloves Garlic pressed
  • 1/2 teaspoon Red Pepper flakes
  • 3 cups or 24 ounces of Marinara
  • 1 cup water
  • 1 Tbsp Italian seasoning
  • 1/2 cup Fresh Parsley, chopped
  • 1 Tbsp Olive Oil
  • 1 cup Parmesan cheese, grated
  • 2 large eggs, beaten
  • 1 1/2 cups Ricotta Cheese
  • 3 cups Mozzarella Cheese, shredded

Instructions

  • Heat a large pot of water to boiling, add pasta and cook for 5 - 6 minutes, al dente. (it will continue to cook in the oven)
    3/4 lb Thin Spaghetti
  • Drain the pasta and let it cool.
  • Preheat your oven to 350°F. Grease a 9x13 baking dish with cooking spray.
  • In a large sauté pan. Turn the heat on, to medium. Slowly cook the sausage, breaking it up into smaller pieces. Cook until the sausage is cooked through, no longer pink anywhere, and lightly browned. Remove the sausage from the pan to a paper towel-lined dish.

  • Drain most of the fat from the pan
  • Add the chopped onions to the pan. Increase the heat to medium-high. Cook, stirring frequently until the onions become translucent. Add the minced garlic and red chili pepper flakes, and cook a minute more.

  • Add the marinara sauce and water to the pan with the onions. Add the sausage back, Italian seasoning, and chopped parsley. Bring to a simmer and reduce the heat to a very low simmer. Cook for 10 to 15 minutes, while you prepare the pasta. Season to taste with salt and pepper.

  • Place half of the pasta in an even layer in the casserole dish.
  • Cover with half of the sauce. Then dot the sauce with half of the ricotta cheese. Sprinkle half of the parmesan over the ricotta layer and then half of the mozzarella. Layer again with the remaining pasta, sauce, parmesan, and mozzarella.

Notes

Originally published 10/12/2015
Cook the pasta al dente in salted water. The pasta will continue to cook while baking.
Make Ahead - Bake the dish, cool completely, wrap tightly, and refrigerate for up to 24 hours. You will probably need to bake it for an additional 10 minutes or more.
Storing and Freezing - Place the cooled casserole in the fridge for up to 3 days or freeze for up to 3 months. Thaw in the fridge overnight.
