Baked Ziti is a lot like lasagna but it's faster since they are lazier layers, but of course it tastes equally as good! Piled high with pasta, sauce and lots of cheeses! The perfect comforting dish.
Preheat oven and boil water: Preheat oven to 350 degrees. Bring a large pot of water to a boil (for pasta).
For the sauce: Heat olive oil in a large saute pan (deep skillet), add onions and saute 2 minutes then add sausage and cook, stirring and breaking up sausage occasionally, until cooked through, adding in garlic during last 1 minute, drain excess fat.
Stir in crushed tomatoes, diced tomatoes, tomato paste, basil, 2 Tbsp parsley and season with salt and pepper to taste. Bring mixture to a light boil, then reduce heat to low, cover and allow to simmer 10 minutes then remove from heat.
Too cook pasta: Cook pasta according to package directions about a minute shy of al dente. Drain pasta while reserving 1/4 cup of the pasta water.
Return pasta to empty pot, immediately add reserved pasta water and 1 cup of the red sauce then toss pasta to coat.
For the cheeses: In a mixing bowl using a fork stir together ricotta, egg, 2 Tbsp parsley and season with salt and pepper. Mix in 1 1/2 cups of the mozzarella and 1/2 cup of the parmesan.
To assemble the ziti: Spray a 13 by 9-inch baking dish with non-stick spray. Spread 1 1/2 cups of the red sauce evenly into bottom of dish, then spread 1/2 of the pasta over sauce then dollop spoonfuls of ricotta mixture all over pasta and flatten slightly.
Top with remaining pasta. Spoon remaining sauce evenly over pasta layer. Sprinkle top evenly with remaining 2 cups of the mozzarella and 1/4 cup parmesan.
To cook the baked ziti: Tent baking dish with foil (don't let it touch the cheese or it will stick) and bake 15 minutes then uncover and bake 10 - 15 minutes longer until cheese is melted throughout. Serve warm.
Notes
For a more browned topping you can broil during last few minutes of baking (as long as you aren't using a glass baking dish).
If you'd like a spicy baked ziti then add 1/4 - 1/2 tsp red pepper flakes to sauce.
