A delightful twist on classic baked spaghetti, combining creamy and cheesy layers for a comforting meal.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking and a perfect bake.
Cook the spaghetti in a large pot of salted boiling water until al dente, then drain.
Slightly undercook the pasta as it will continue to cook in the oven.
In a frying pan, cook the Italian sausage over medium heat until browned and fully cooked, then drain any excess grease.
Breaking the sausage into small pieces ensures even cooking and distribution.
In a mixing bowl, combine the marinara sauce and sour cream until smooth.
Mixing the sauce and sour cream creates a creamy base for the dish.
In the baking dish, spread a thin layer of the sauce mixture at the bottom.
This prevents the pasta from sticking to the dish.
Toss the cooked spaghetti with the remaining sauce mixture, cooked sausage, red pepper flakes, and half of the Parmesan cheese.
Ensure the pasta is evenly coated for consistent flavor.
Transfer the spaghetti mixture to the baking dish and spread evenly.
Press gently to create an even layer.
Top with the shredded mozzarella cheese and the remaining Parmesan cheese.
Distribute the cheese evenly for a golden crust.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
For a crispy top, broil for the last 2 minutes.
Let the dish cool for 10 minutes before serving.
Cooling allows the layers to set for easier serving.
