- For the Pasta:
- 1 pound (450g) penne or rigatoni pasta
- 1 tablespoon olive oil (for cooking pasta)
- Salt (for pasta water)
- For the Sausage & Sauce:
- 1 tablespoon olive oil
- 1 pound (450g) Italian sausage, casings removed (mild or hot, your choice!)
- 1 medium yellow onion, chopped
- 3 cloves garlic, minced
- 1 (28 ounce) can crushed tomatoes
- 1 (15 ounce) can tomato sauce
- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil
- 1/4 teaspoon red pepper flakes (optional, for a little kick)
- Salt and freshly ground black pepper to taste
- 1/2 cup chicken or vegetable broth (optional, for thinning sauce)
- For the Cheese Layers:
- 15 ounces (about 1 3/4 cups) ricotta cheese
- 1 large egg

- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 cups shredded mozzarella cheese
Step-by-Step Instructions
-
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the penne or rigatoni pasta and cook according to package directions until al dente. This means it should still have a slight bite. Drain the pasta well and toss with 1 tablespoon of olive oil to prevent sticking. Set aside.
Small tip: Cooking pasta al dente is key for casseroles, as it will continue to cook in the oven.
-
Step 2: Brown the Sausage
While the pasta cooks, heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Add the Italian sausage, breaking it up with a spoon as it cooks. Brown the sausage thoroughly until no pink remains, about 5-7 minutes. Drain any excess grease from the pan.
Small tip: Draining the grease helps keep the casserole from being too oily.
-
Step 3: Sauté Aromatics and Build Sauce
Add the chopped onion to the skillet with the cooked sausage and cook until softened, about 3-4 minutes. Stir in the minced garlic and cook for another minute until fragrant. Pour in the crushed tomatoes and tomato sauce. Add the dried oregano, dried basil, and red pepper flakes (if using). Season with salt and pepper to taste. If the sauce seems too thick, add a little chicken or vegetable broth. Bring to a simmer and cook for 10 minutes, allowing the flavors to meld.
Small tip: Taste the sauce and adjust seasonings as needed before combining with other ingredients.
-
Step 4: Prepare the Ricotta Mixture
In a medium bowl, combine the ricotta cheese, large egg, 1/4 cup grated Parmesan cheese, chopped fresh parsley, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mix everything together until well combined. This creamy mixture will add a wonderful richness to your casserole.
Small tip: Using fresh parsley adds a brighter flavor than dried parsley in this mixture.
-
Step 5: Assemble the Casserole
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Spread about 1 cup of the sausage and tomato sauce mixture evenly on the bottom of the prepared dish. Layer half of the cooked pasta over the sauce. Dollop spoonfuls of the ricotta mixture over the pasta, then top with 1 cup of shredded mozzarella cheese. Repeat with another layer of the remaining pasta, then the remaining sausage and tomato sauce.
Small tip: Don’t worry about perfect layers; it will all melt together beautifully.
-
Step 6: Bake to Perfection
Sprinkle the remaining 1 cup of shredded mozzarella cheese over the top of the casserole. You can also add an extra sprinkle of Parmesan cheese if you like. Cover the baking dish loosely with aluminum foil. Bake for 20 minutes, then remove the foil and continue baking for another 10-15 minutes, or until the cheese is bubbly and lightly golden brown. Let it rest for 5-10 minutes before serving.
Small tip: Resting the casserole allows the layers to set, making it easier to serve clean slices.
Tips & Variations
- Gluten-Free Option: Simply use your favorite gluten-free pasta in place of regular pasta. The rest of the ingredients are naturally gluten-free.
- Vegan or Vegetarian Option: Swap the Italian sausage for plant-based Italian sausage crumbles or cooked lentils seasoned with Italian herbs. For the cheese, use vegan ricotta and mozzarella alternatives.
- Add More Vegetables: Boost the veggie content by sautéing diced bell peppers, mushrooms, or zucchini with the onion and garlic. Fresh spinach can also be stirred into the sauce during the last few minutes of simmering.
- Spicy Version: Increase the red pepper flakes in the sauce to 1/2 or even 1 teaspoon. You can also use hot Italian sausage for an extra kick.
- Creamier Texture: For an even richer, creamier sauce, stir in 1/4 cup of heavy cream or a dollop of cream cheese into the tomato sauce before combining with the pasta.

Health Benefits
This Italian Sausage and Pasta Casserole offers several health benefits from its key ingredients.
Italian sausage provides a good source of protein, which is essential for muscle repair, growth, and overall body function. When choosing sausage, opt for leaner varieties if you’re watching fat intake.
Tomatoes, found in the crushed tomatoes and tomato sauce, are rich in vitamins C and K, potassium, and an antioxidant called lycopene. Lycopene is particularly beneficial for heart health and may help protect against certain types of cancer.
Dairy products like ricotta, mozzarella, and Parmesan cheese contribute significantly to your calcium intake, which is crucial for strong bones and teeth. They also provide additional protein and B vitamins.
Onions and garlic not only add incredible flavor but also boast impressive health benefits. They contain antioxidants and compounds that may help reduce inflammation and boost immune function.
