Ingredients

Uncooked Spaghetti: 1 pound of pasta cooked al dente to provide a firm texture that holds up well when baked.
Italian Sausage: 1 pound of flavorful sausage meat, either ground or removed from casings, adds rich, seasoned protein.
Medium Onion: Half an onion, finely chopped to impart sweetness and balance the sausage’s savoriness.
Garlic Cloves: Four cloves minced to enhance the sauce with aromatic, pungent depth.
Red Pepper Flakes (Optional): Half a teaspoon for a gentle heat that can be adjusted to taste.
Marinara Sauce: Two 24-ounce jars bringing bright tomato acidity and robust herbal flavors.
Mozzarella Cheese: Two cups shredded to melt beautifully on top, forming a golden, cheesy crust.
Cream Cheese: One 8-ounce block softened to contribute a smooth, tangy richness in the cheese layer.
Ricotta Cheese: 8 ounces provide a creamy, slightly grainy texture that blends perfectly in the filling.
Parmesan Cheese: One cup freshly grated, adding sharp, nutty notes to the cheese mixture.
Garlic Powder: Half a teaspoon to enhance the cheese layer ’s savory flavor.
Dried Oregano: Half a teaspoon for earthy, aromatic Italian seasoning in the cheese blend.
Salt & Pepper: To taste, balancing all the flavors throughout the dish.

Instructions

Preheat the Oven and Prepare Cheese Mixture: Set your oven to 375°F and position the rack in the upper third to promote even browning. In a medium bowl, combine softened cream cheese, ricotta, parmesan, garlic powder, and oregano. Stir this mixture until smooth and creamy, which ensures an even, flavorful cheese layer within the casserole.
Cook the Pasta Al Dente: Boil a large pot of salted water for the spaghetti. Cook the pasta for 2 minutes less than the package recommends to keep it firm when baked. Drain and return it to the cooking pot to combine later with the sausage and sauce.
Brown Italian Sausage with Onion: Heat a skillet over medium-high heat and add the sausage along with the chopped onion. Break the meat into small pieces as it cooks for around 10 minutes until it’s nicely browned. This step builds deep flavor by caramelizing the meat and softening the onion.
Add Garlic and Red Pepper Flakes: Stir in minced garlic and optional red pepper flakes to the sausage mixture. Cook for an additional minute to let the garlic release its fragrance and the slight heat infuse the meat, then carefully spoon out any excess fat for a balanced dish.
Combine Pasta, Sausage, and Sauce: Transfer the skillet sausage mixture into the pot with the cooked spaghetti. Pour in both jars of marinara sauce and toss everything together until the pasta is fully coated. This evenly distributes the rich flavors throughout each bite.
Layer the Casserole: Spread half of the pasta and sauce mix evenly in a 9×13 inch baking dish. Next, dollop and spread the cheese mixture over the pasta layer; the texture may be slightly uneven but ensures a creamy cheesiness throughout. Top with the remaining pasta mixture and finally sprinkle the shredded mozzarella evenly on top.
Bake with Foil and Broil for Finishing Touch: Cover the casserole dish with foil and bake for 30 minutes to meld the flavors. Remove the foil and broil for a few minutes, watching closely, until the top layer of cheese bubbles and turns golden brown—a visually appealing and delicious crust.
Rest and Serve: Allow the casserole to rest for 5 to 10 minutes after baking. This step helps the layers settle and makes it easier to cut into portions. Season with salt and pepper as needed before serving for a perfectly balanced dish.
