A baked pasta dinner is comfort food at its finest, it has all the cozy, cheesy goodness you crave without the fussy assembly of lasagna. This one-dish wonder comes together quickly on the stovetop, then finishes beautifully in the oven with melted cheese and a golden crust.
I love how forgiving this dish is for busy weeknights. You brown some sausage, simmer a simple sauce, toss everything together, and let the oven do the heavy lifting while you relax with your family.
The result is a bubbling, satisfying pasta that feeds a crowd and tastes even better the next day. Trust me, this will become a regular rotation in your dinner lineup.
Simple Ingredients
This recipe keeps things simple with pantry staples and a pound of Italian sausage for flavor. The combination of tomato puree, pasta, and two cheeses creates that rich, satisfying sauce that makes everyone ask for seconds.
- Rigatoni pasta: The ridges catch and hold the sauce beautifully. You want a sturdy shape that won’t fall apart when mixed.
- Italian sausage: Mild or spicy, choose based on your family’s heat preference. The meat adds savory depth without needing extra seasoning.
- Tomato puree: This concentrated sauce creates a rich base faster than crushed tomatoes. A single can is all you need.
- Mozzarella cheese: Use the shredded kind for even melting. Divide it so some goes into the sauce and the rest tops the dish for that gorgeous golden finish.
- Parmesan cheese: A little goes a long way. It adds a sharp, nutty note that balances the creamy mozzarella.
- Pasta water: Save a cup of the starchy cooking water, it helps the sauce coat the pasta evenly and keeps everything creamy.
Let's Make Baked Pasta Dinner
Here’s how to build this dinner from start to finish.
Step 1: Sauté the aromatics
Heat olive oil in a large pot or Dutch oven over medium heat. Add diced onion and cook for 3 to 4 minutes until soft, then stir in minced garlic and cook for another minute until fragrant.
Step 2: Brown the sausage
Crumble the Italian sausage into the pot and cook, breaking it into small pieces with a spatula, until no pink remains. Drain off any excess grease so the sauce isn’t oily.
Step 3: Simmer the sauce
Pour in the can of tomato puree along with ¼ cup water, salt, pepper, and oregano. Lower the heat and let it bubble gently for 30 minutes so the flavors get to know each other.
Step 4: Cook the pasta
While the sauce simmers, boil the rigatoni in salted water until just shy of tender, you want it slightly firm since it’ll finish cooking in the oven. Save 1 cup of pasta water, then drain the rest.
Step 5: Combine everything
Stir the cooked pasta, 1½ cups mozzarella, and ½ cup pasta water into the sauce. If it looks dry, add more pasta water a splash at a time until it’s creamy but not soupy.
Step 6: Bake until golden
Preheat your oven to 350°F. Spread the pasta mixture into a 9×13-inch baking dish, top with the remaining mozzarella and parmesan, and bake for 25 to 30 minutes until it’s bubbling and the cheese is golden brown.
Tips From My Kitchen
- Don’t skip saving the pasta water, that starchy liquid is what makes the sauce silky and helps it cling to every piece of pasta.
- Cook the pasta just under al dente. It continues to soften in the oven, so you want a little firmness left.
- If your sausage is very fatty, drain it well after browning to avoid a greasy finished dish.
- Let the baked pasta rest for 5 minutes after pulling it from the oven. It’ll set up slightly and be easier to serve.
- This dish is forgiving, if your sauce looks a bit thick, thin it with a little pasta water. If it’s too loose, just bake it a few minutes longer.
Equipment You'll Need

Common Questions
Can I make this ahead of time?
Absolutely. Assemble the entire dish up to the baking step, cover it, and refrigerate for up to 24 hours. Add 5 to 10 extra minutes to the baking time if baking straight from the fridge.
Why do you use rigatoni instead of other pasta shapes?
Rigatoni’s tubes and ridges trap the sauce beautifully, giving you a bite of sauce with every forkful. Penne or ziti work too, but avoid tiny shapes like ditalini that can get mushy.
Is the 30-minute simmer time necessary?
It really helps the flavors develop and deepen. If you’re in a rush, you can shorten it to 15 to 20 minutes, but the sauce won’t be quite as rich.
How do I know when it's done baking?
Look for the sauce bubbling around the edges and the cheese on top turning golden brown. If it’s still pale, give it another 5 minutes. You want that golden crust for texture and flavor.
Make Ahead and Storage
Store
Keep leftovers in an airtight container in the fridge for up to 4 days. The pasta will absorb the sauce as it sits, making it even more flavorful.
Freeze
This dish freezes beautifully for up to 3 months. Cool completely, transfer to a freezer-safe container, and label with the date.
Reheat
Thaw overnight in the fridge, then warm in a 350°F oven covered with foil for 20 to 25 minutes until heated through. Add a splash of water or broth if it looks dry.
