This hearty Baked Italian Sausage Pasta Casserole With Mozzarella is made with savory ground pork, tender penne, and a rich tomato sauce, ready in just 50 minutes. The best part is pulling the hot dish from the oven as the cheese bubbles fiercely and the edges turn a perfect golden brown. I love making this meal on busy weeknights because it delivers maximum comfort with minimal cleanup.
Why This Classic Works
I used to overcomplicate my pasta bakes by making complex béchamel sauces or slow-simmering my own ragu for hours. I eventually learned that the high fat content and spices in good quality Italian sausage provide enough flavor to transform a simple jarred marinara into something that tastes homemade in a fraction of the time.
The real secret to this dish, however, is undercooking the pasta slightly before baking. If you boil the noodles until they are fully soft, they will turn to mush in the oven; stopping two minutes early ensures they soak up the sauce while maintaining a perfect al dente bite.
Baked Italian Sausage Pasta Casserole With Mozzarella Ingredients
- 1 lb (450g) Italian sausage: Mild or spicy, bulk or casings removed.
- 1 lb (450g) penne pasta: Ziti or rotini also work well.
- 24 oz (700g) marinara sauce: Use a high-quality jarred sauce.
- 1 yellow onion: Finely chopped.
- 3 cloves garlic: Minced.
- 3 cups mozzarella cheese: Shredded, divided.
- 1/2 cup Parmesan cheese: Grated.
- 1 tsp dried oregano: Adds herbal depth.
- 1/2 tsp dried basil: Or use fresh basil for garnish.
- Salt and black pepper: To taste.
How To Make Baked Italian Sausage Pasta Casserole With Mozzarella
- Boil the Pasta: Bring a large pot of salted water to a boil and cook the penne for 2 minutes less than the package directions (it should still be firm). Drain and set aside.
- Brown the Sausage: While the water heats, add the sausage and chopped onion to a large skillet over medium-high heat. Break the meat apart with a spoon and cook until browned and crumbled, about 6-8 minutes.
- Simmer the Sauce: Stir the minced garlic, dried oregano, and basil into the skillet and cook for 1 minute until fragrant. Pour in the marinara sauce, reduce heat to low, and simmer for 5 minutes to meld the flavors.
- Combine Ingredients: Add the drained pasta to the skillet (or a large bowl if your skillet is too small) and toss until every noodle is coated in the meat sauce. Stir in 1 cup of the mozzarella cheese.
- Assemble the Casserole: Pour half of the pasta mixture into a greased 9×13 inch baking dish. Sprinkle with half of the remaining mozzarella and Parmesan. Top with the remaining pasta mixture and finish with the rest of the cheese.
- Bake: Bake at 375°F (190°C) for 20-25 minutes until the cheese is melted and bubbling. For a browned top, broil for the last 2-3 minutes.
Recipe Tips
- Shred Cheese Yourself: Pre-shredded bags of cheese contain anti-caking agents like potato starch that prevent them from melting smoothly. Grating a block of low-moisture mozzarella yields the best stretch and melt.
- Add Veggies: To boost the nutrition without changing the flavor profile too much, sauté diced bell peppers or stir in fresh spinach with the onions during the browning step.
- Watch the Salt: Italian sausage and Parmesan are naturally salty, so taste your sauce before adding extra salt to ensure it isn’t overpowering.
What To Serve With Baked Italian Sausage Pasta Casserole With Mozzarella
Since this dish is rich and heavy on carbs, I always serve it with a crisp green salad tossed in a sharp vinaigrette to cut through the cheese. Garlic bread is also a non-negotiable side dish in my house, perfect for scooping up any extra sauce left on the plate.
How To Store
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. This casserole also freezes beautifully; simply assemble it in a foil container, cover tightly, and freeze for up to 3 months, thawing in the fridge overnight before baking.
FAQs
- Can I use turkey sausage instead? Yes, turkey sausage is a great leaner alternative and works perfectly in this recipe, though you may want to add a pinch of fennel seeds to mimic the traditional pork flavor.
- Do I have to bake this dish? Baking helps melt the cheese and marry the flavors, but if you are short on time, you can stir all the cheese directly into the skillet and serve it as a stove-top pasta.
- Can I make this ahead of time? Absolutely, you can assemble the entire casserole, cover it with foil, and refrigerate it for up to 24 hours before baking; just add 5-10 minutes to the cook time if it’s going into the oven cold.
