Recipe Information
Ingredients
- 12 oz Rotini pasta
- 1 lb Ground Italian sausage
- 1 Yellow onion, diced
- 3 Garlic cloves, minced
- 2 cups Marinara sauce
- 1 cup Heavy cream
- 2 cups Shredded mozzarella cheese
- 1 cup Shredded cheddar cheese
- 1 cup Parmesan cheese, grated
- 1 tbsp Olive oil
- 1 tsp Salt
- 0.5 tsp Black pepper
- 1 tsp Dried Italian seasoning
- 0.25 tsp Red pepper flakes (optional)
- 2 tbsp Fresh parsley (for garnish)
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish and set aside.
Cook the rotini pasta in a large pot of salted boiling water according to the package instructions. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the ground Italian sausage and cook until browned, breaking it apart with a spatula, about 7-8 minutes.
Add the diced onion and minced garlic to the skillet with the sausage. Cook for 3-4 minutes, stirring occasionally, until the onion becomes translucent.
Stir in the marinara sauce, heavy cream, salt, black pepper, Italian seasoning, and red pepper flakes (if using). Allow the mixture to simmer for 5 minutes.
Remove the skillet from heat and stir in 1 cup of shredded mozzarella and 1/2 cup of Parmesan cheese until melted and combined.
In a large mixing bowl, combine the cooked rotini pasta with the sausage sauce. Mix until the pasta is evenly coated.
Transfer the mixture to the prepared casserole dish. Spread it out evenly.
Sprinkle the top of the casserole with the remaining mozzarella cheese, cheddar cheese, and Parmesan cheese.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden.
Remove the casserole from the oven and let it rest for 5 minutes. Sprinkle with fresh parsley before serving.
Serve warm and enjoy!
