Dinner doesn’t get much easier than this Baked Tomato Sausage Rigatoni. Dry rigatoni, Italian sausage, and veggies cook in the oven submerged in a marinara-chicken broth mixture. The dish is then finished off with some heavy cream and cheese. The pasta soaks up the liquid as it bakes until tender for incredible flavor – and no need for separate pots, so clean up is easy!

This baked rigatoni with sausage is a super easy pasta dish where everything gets cooked in one pan in the oven – there’s no need for separate pots to cook the rigatoni or the Italian sausage ahead of time, yet the pasta still ends up tender and al dente. I think it’s even more flavorful because it cooks right in the tomato sauce and broth, instead of plain salted water. I stirred in a bit of heavy cream, fresh parmesan, and spinach at the end for some creaminess and extra veggies. It’s so good!
Tips & Variations
- Make sure the pasta is submerged. Since the pasta is not cooked before baking, it’s important to ensure that all of it is completely submerged in liquid before baking and the casserole dish is tightly covered in foil.
- Use any Italian sausage. Any bulk Italian sausage works great in this dish, choose from sweet, mild, or spicy depending on your preference.
- Try it with ground beef. Ground beef can be used in place of the Italian sausage, if that’s what you have on hand. Sometimes I’ll even use a 50/50 mix of both ground meats for a variety in flavor.
- Make it vegetarian. To make a vegetarian baked rigatoni, simply omit the Italian sausage. You could swap it for another chopped vegetable, too.

Serving Suggestions
With pasta, veggies, and meat right in one dish, this baked tomato sausage rigatoni can easily stand on its own as the entire meal. That said, I am a big fan of pasta with a simple side salad or caesar salad to start the meal. You can never go wrong with a side of breadsticks or crusty dutch oven bread either.
How To Store & Reheat Leftovers
- Fridge. Store leftover baked rigatoni in the fridge for 3 to 4 days. If I still have a decent amount of leftovers, I usually just cover the baking dish with foil and refrigerate it. Otherwise, store leftovers in an airtight container.
- Reheat. The entire baking dish of rigatoni can be reheated in the oven at 350F until warmed through. Cover it with foil to prevent it from drying out. Individual servings can be easily reheated in the microwave as well.

I made this with GF rigatoni and it was delicious!! Would 100% make again.
This sounds wonderful! I’m anxious to try it.
Is there a way to make this without the heavy cream? Half and half, fat-free half and half, or something else? More broth?
Thank you.
You can use half-n-half instead. Enjoy!
