This easy Baked Rigatoni with sausage, marinara sauce, and two different types of cheese is a classic pasta bake that’s pure comfort food! Pair the hearty, satisfying casserole with a Caesar salad and garlic bread for the ultimate family meal. It’s also a simple make-ahead dinner for busy days!

Italian Rigatoni Bake
Baked rigatoni is a casserole that’s made with rigatoni pasta and a Neapolitan-style tomato-based sauce that’s popular in Italian-American cuisine. Rigatoni is a tube-shaped pasta of varying lengths and diameters, which originated in Italy. It’s larger than penne and ziti, and sometimes slightly curved, though not as curved as elbow macaroni.
To make baked rigatoni, the pasta is typically boiled first, while the sauce is prepared separately. The cooked and drained rigatoni is then tossed with the sauce and sausage, layered in a dish with mozzarella and Parmesan cheeses, and then baked in the oven.
What is the difference between Rigatoni and ziti?
Rigatoni and ziti might look similar at first, but they vary in both size and texture. First, rigatoni is larger than ziti, and often slightly curved. While the rigatoni has a larger opening, ziti is often longer. Rigatoni has ridges or grooves (which helps the sauce cling to the pasta), while ziti is often smooth.
Those differences aside, we’re not too particular around here. If you need to substitute penne or ziti for the rigatoni in this recipe, feel free! The pasta bake will still be delicious. Just make sure that you follow the cooking instructions for very al dente penne or ziti, according to your specific package.

Ingredients
This is just a quick overview of the simple ingredients that you’ll need for an easy baked rigatoni recipe. As always, specific measurements and step-by-step instructions are included in the printable recipe box at the bottom of the post.
- Rigatoni pasta: use an entire 1-lb. box of dry pasta. I like “mezzi rigatoni” which is slightly shorter than regular rigatoni (and therefore easier to eat without cutting).
- Olive oil: to cook the sausage and onion.
- Italian sausage: sweet or spicy, any variety will work. You can buy a pound of ground Italian sausage, or purchase the links and remove the casings yourself.
- Onion: adds savory flavor to the casserole. I use a sweet Vidalia onion, but a white or yellow onion is fine, too.
- Garlic and crushed red pepper flakes: add flavor and a bit of kick to the sauce.
- Marinara sauce: pick a high-quality store-bought brand for a great shortcut. I like Rao’s marinara.
- Fresh basil: a classic ingredient in any tomato-based Italian dish. Fresh herbs always have the best flavor, but you can substitute with about 1 tablespoon of dried basil when necessary.
- Kosher salt and black pepper: to enhance the other flavors in the dish. Make sure to use plenty of salt in the pasta cooking water, too.
- Mozzarella cheese and Parmesan cheese: two different types of cheese add flavor to the casserole and hold it all together. The more cheese the better, right?!

How to Make Baked Rigatoni with Sausage
While there are quite a few steps involved in preparing this dish, none of it is difficult! This recipe doesn’t need to be too labor-intensive either, so long as you have various components cooking at the same time. For instance, you can brown the sausage and simmer the sauce while the pasta boils. Let’s get started…
- Boil the rigatoni just until very al dente, about 12 minutes. Drain.
- Meanwhile, prepare the sausage and marinara sauce.
- Add the cooked pasta to the meat sauce.
- Spread half of the pasta mixture in the bottom of a greased 9 x 13-inch baking dish.
- Top with half of the mozzarella and Parmesan.
- Repeat the layers with the remaining ingredients.
- Bake, uncovered, in a 400ยฐF oven until hot and bubbly.

How Long to Bake Rigatoni Casserole
Since all of the ingredients in the casserole are already cooked, you just need to bake the dish until it’s hot, bubbly, and slightly crisp on top. This will take about 20 minutes in a 400ยฐF oven. You don’t want to cook it too long, or the pasta will become mushy and overdone.

What to Serve with Baked Rigatoni with Italian Sausage
Here are some good side dishes for baked rigatoni with sausage:

Make Ahead
Assemble the dish up to 2 days in advance. Keep it covered in the refrigerator. When ready to bake, allow the dish to sit on the counter and come to room temperature for at least 30-60 minutes before baking according to the recipe instructions. If the dish is cold when it goes into the oven, you will likely need to add some extra baking time.
To Freeze
Baked rigatoni can be frozen either before or after baking. The quality is best if you assemble the casserole in advance (in a 9 x 13-inch freezer-safe dish) and freeze before baking. Wrapped tightly, the baked rigatoni will last in the freezer for up to 3 months. When youโre ready to cook it, defrost in the refrigerator for 24 hours, then proceed with the Make Ahead instructions above.
Storage
Leftover baked rigatoni will keep in the refrigerator for 3-4 days. Cover and reheat leftovers in a 350ยฐF oven for 25-30 minutes, or until warmed through. You can also reheat individual portions in a microwave for 1-2 minutes on high power.

Baked Rigatoni Recipe Variations
- Don’t have rigatoni pasta on hand? Substitute with ziti or penne pasta.
- Add baby spinach to the sauce. It will wilt almost instantly and blend into the casserole.
- Use ground beef or ground turkey instead of the Italian sausage. Since you will be missing the extra flavor boost from the herbs and seasonings in the sausage, you might want to add some extra herbs and seasonings to the sauce.
- Cooking for a smaller family? Cut the ingredients in half and bake the rigatoni in an 8-inch square dish. Alternatively, you can prepare the full recipe, but divide the ingredients between two 8-inch square dishes. Bake one for now, and freeze the other for later!
- Try a simple baked rigatoni with no meat for an easy vegetarian meal!
Tips for the Best Baked Rigatoni Recipe
- I like “mezzi rigatoni,” which is slightly shorter than regular rigatoni. It’s easier to eat without cutting!
- Undercook the pasta slightly, because it will continue to cook while it bakes in the oven. You don’t want to end up with overdone, mushy rigatoni. For instance, if my box of rigatoni suggests 12-14 minutes for al dente, I boil the pasta for no more than 12 minutes.
- Bake the pasta uncovered. This recipe has plenty of sauce and cheese on top to keep the baked rigatoni from drying out. Be careful that you don’t bake the casserole for too long. Since all of the ingredients are already cooked, the dish will only need about 15 minutes in the oven. It should get hot, bubbly, and slightly crispy on the edges.
- Fresh herbs really brighten up a warm, cozy casserole. I love to garnish with parsley, basil, oregano or thyme. Some extra grated Parmesan on top is also a great touch!
