Before You Get Started
A few simple tips will help you get the best results with this baked rigatoni recipe.
⇢ Undercook the pasta slightly. The rigatoni continues cooking in the oven, so boil it just until very al dente. If your package says 12-14 minutes, pull it closer to 11. This prevents mushy, overdone pasta in the final dish.
⇢ Bake uncovered. You might be tempted to cover the dish with foil, but don’t. The generous amount of sauce and cheese keeps everything moist, and baking uncovered lets the top get golden and slightly crisp around the edges.
⇢ Watch the clock. Since all the ingredients are already cooked before the casserole goes in the oven, it only needs about 20 minutes to bake. You’re just heating it through and melting the cheese. Over-baking leads to dry, mushy pasta.

How to Make Baked Rigatoni with Sausage
This recipe comes together in stages, but nothing is complicated. You can have the sausage browning while the pasta boils to save time.
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the rigatoni and cook according to package directions for very al dente. You want it just slightly underdone since it will finish cooking in the oven.
Drain the pasta and set it aside. No need to rinse it.
⇢ A note on pasta shape: I like “mezzi rigatoni”, which is slightly shorter than regular rigatoni and easier to eat without cutting. If you can’t find rigatoni, penne or ziti work well too. Just follow the package directions for al dente timing.
Step 2: Make the Meat Sauce
While the pasta cooks, heat olive oil in a large skillet or Dutch oven over medium-high heat. Add the Italian sausage (casings removed) and diced onion. Cook until the sausage is browned and no longer pink, about 5-7 minutes, breaking it into crumbles as it cooks.
Add the garlic and cook for about 30 seconds, just until fragrant. Don’t let it burn.
Stir in the marinara sauce, fresh basil, crushed red pepper flakes, and salt and pepper to taste. Let everything simmer together over medium-low heat for 5-7 minutes. The sauce will thicken slightly and the flavors will come together.
⇢ Use a good marinara. Since the sauce is doing a lot of heavy lifting here, a high-quality jarred marinara makes a real difference. I like Rao’s marinara for its rich flavor.
Add the drained pasta to the sauce and toss everything together until the rigatoni is well coated.

Step 3: Layer and Bake
Preheat your oven to 400°F and grease a 9 x 13-inch baking dish.
Spread half of the pasta mixture in the bottom of the prepared dish. Sprinkle with half of the mozzarella cheese and half of the Parmesan cheese.
Add the remaining pasta mixture on top, then finish with the remaining mozzarella and Parmesan. You want a generous layer of cheese on top for that golden, bubbly finish.

Bake uncovered for about 20 minutes, until the casserole is hot and bubbly and the cheese is melted with golden spots. The edges should be slightly crispy.
Let the baked rigatoni rest for 5-10 minutes before serving. This helps it set up a bit and makes it easier to scoop out nice portions. Garnish with fresh basil or parsley if you like.

Storage, Freezing & Make-Ahead Tips
Make Ahead: Assemble the casserole up to 2 days in advance and keep it covered in the refrigerator. When you’re ready to bake, let the dish sit on the counter for 30-60 minutes to take the chill off, then bake according to the recipe. If it’s still cold when it goes in the oven, you may need to add a few extra minutes of baking time.
Freezing: Baked rigatoni freezes beautifully. For best results, assemble the casserole in a freezer-safe 9 x 13-inch dish and freeze it before baking. Wrap tightly with plastic wrap and foil. It will keep in the freezer for up to 3 months. When ready to cook, thaw in the refrigerator for 24 hours, then follow the make-ahead instructions above.
Leftovers: Store leftover baked rigatoni in an airtight container in the refrigerator for 3-4 days. Reheat covered in a 350°F oven for 25-30 minutes, or microwave individual portions for 1-2 minutes.
Recipe Variations
- Different pasta: Substitute penne or ziti if you don’t have rigatoni on hand. Just follow the package directions for al dente.
- Ground beef or turkey: Swap the Italian sausage for ground beef or ground turkey. Since you’ll lose the seasoning from the sausage, add a teaspoon of Italian seasoning to the sauce.
- Add vegetables: Stir a few handfuls of baby spinach into the sauce. It wilts almost instantly and blends right in.
- Smaller batch: Cut the ingredients in half and bake in an 8-inch square dish. Or make the full recipe in two 8-inch dishes, bake one now and freeze one for later.
- Meatless: Try this simple baked rigatoni for an easy vegetarian version.
Frequently Asked Questions
Can I use a different pasta shape?
Yes! Penne and ziti are the closest substitutes for rigatoni. Any sturdy tube-shaped pasta will work well because it holds the sauce and cheese inside. Just follow the package directions for al dente cooking time, and remember to undercook it slightly since it finishes cooking in the oven.
How do I keep baked pasta from drying out?
The key is using enough sauce and not over-baking. This recipe has plenty of marinara to keep the pasta moist. Bake uncovered (covering traps steam and can make the cheese soggy) and pull it from the oven as soon as the cheese is melted and bubbly, about 20 minutes. Since everything is already cooked, you’re just heating it through.
