Ingredients
Gather these simple, pantry-friendly ingredients for your pasta bake:
- 1 lb rigatoni or penne pasta
- 1 lb Italian sausage (mild or spicy, casings removed)
- 1 tbsp olive oil
- 1 small onion, finely chopped
- 3 garlic cloves, minced
- 1 tsp dried Italian seasoning
- ½ tsp crushed red pepper flakes (optional, for heat)
- 2 cups marinara sauce (store-bought or homemade)
- 1 cup heavy cream
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 2 tbsp fresh parsley, chopped (plus extra for garnish)
- Salt and black pepper, to taste
Instructions
Follow these simple steps to make a rich and flavorful pasta bake:
- Preheat the oven:
Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish with cooking spray or oil. - Cook the pasta:
Boil the pasta in salted water until just al dente according to the package instructions. Drain and set aside. - Cook the sausage:
Heat the olive oil in a large skillet over medium heat. Add the Italian sausage and cook, breaking it up into crumbles, until browned and fully cooked. Remove from the skillet and set aside. - Sauté the aromatics:
In the same skillet, add the chopped onion and cook until softened, about 3–4 minutes. Stir in the garlic, Italian seasoning, and red pepper flakes, and cook for another 1 minute until fragrant. - Make the sauce:
Pour the marinara sauce and heavy cream into the skillet, stirring to combine. Simmer for 5 minutes, then stir in the cooked sausage. Season with salt and pepper to taste. - Combine pasta and sauce:
In a large mixing bowl, combine the cooked pasta and sausage sauce. Add half of the mozzarella, half of the Parmesan, and 1 tablespoon of parsley. Stir until evenly coated. - Assemble the bake:
Transfer the pasta mixture to the prepared baking dish. Sprinkle the remaining mozzarella and Parmesan cheese evenly over the top. - Bake until bubbly:
Place the dish in the oven and bake for 20–25 minutes, or until the cheese is melted and bubbly. For a golden top, broil on high for the last 2–3 minutes. - Garnish and serve:
Remove from the oven, sprinkle with extra parsley, and let it cool slightly before serving. Enjoy this cheesy, hearty masterpiece!
