How to Make Cheesy Baked Rigatoni with Tomato Sauce
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with olive oil or nonstick cooking spray.
Set it aside while you prepare the pasta and sauce.
2. Cook the Rigatoni
Bring a large pot of generously salted water to a boil.
Add the rigatoni.
Cook it for approximately 2 minutes less than the package directions recommend.
The pasta should be slightly firmer than al dente because it will continue cooking in the oven.
Before draining, reserve approximately ½ cup of pasta water.
Drain the rigatoni well.
Do not rinse it.
Set aside.
3. Sauté the Onion
Heat the olive oil in a large saucepan or deep skillet over medium heat.
Add the diced onion.
Cook for approximately 4–5 minutes, stirring occasionally, until softened and translucent.
Avoid browning the onion too aggressively.
You want it soft and sweet so it blends smoothly into the tomato sauce.
4. Add the Garlic and Tomato Paste
Add the minced garlic.
Cook for approximately 30–60 seconds, stirring constantly, until fragrant.
Add the tomato paste.
Cook for another 1–2 minutes.
Allowing the tomato paste to cook briefly helps deepen its flavor and removes the raw tomato taste.
5. Prepare the Tomato Sauce
Pour in the crushed tomatoes and tomato sauce.
Add the Italian seasoning, basil, oregano, garlic powder, onion powder, salt, black pepper, red pepper flakes, and sugar if using.
Stir until everything is well combined.
Bring the sauce to a gentle simmer.
Reduce the heat to low.
Cook uncovered for approximately 15–20 minutes, stirring occasionally.
The sauce should thicken slightly and develop a richer flavor.
Stir in the fresh basil or parsley just before removing it from the heat.
6. Prepare the Ricotta Mixture
In a medium bowl, combine the ricotta, ½ cup mozzarella, ¼ cup Parmesan, egg, Italian seasoning, garlic powder, and black pepper.
Stir until smooth and evenly combined.
The egg helps the ricotta layer hold together during baking.
Set the cheese mixture aside.
7. Combine the Pasta and Sauce
Add approximately two-thirds of the tomato sauce to the drained rigatoni.
Toss gently until every piece of pasta is coated.
If the mixture seems dry, add a small splash of reserved pasta water.
The pasta should be generously sauced because it will absorb more liquid while baking.
Reserve the remaining tomato sauce for layering.
8. Assemble the First Layer
Spread a thin layer of reserved tomato sauce over the bottom of the prepared baking dish.
Add half of the sauced rigatoni.
Spread it into an even layer.
Spoon half of the ricotta mixture over the pasta in small dollops.
Sprinkle with approximately ¾ cup mozzarella.
Add a light sprinkle of Parmesan.
9. Add the Second Layer
Add the remaining rigatoni.
Spread the remaining ricotta mixture over the pasta.
Spoon the remaining tomato sauce evenly over the top.
Sprinkle generously with the remaining mozzarella and Parmesan.
Make sure the cheese reaches the edges so the casserole develops plenty of bubbling, golden spots.
10. Bake the Rigatoni
Cover the baking dish loosely with aluminum foil.
Bake for approximately 20 minutes.
Remove the foil.
Continue baking uncovered for another 15–20 minutes.
The sauce should be bubbling around the edges and the cheese should be completely melted.
11. Brown the Cheese
For a more golden topping, switch the oven to broil for approximately 1–2 minutes.
Watch closely.
The cheese can go from golden to burned very quickly.
Remove the casserole when the top develops lightly browned and bubbly spots.
12. Rest Before Serving
Remove the baked rigatoni from the oven.
Allow it to rest for approximately 10 minutes.
This resting period helps the cheese and sauce settle, making the pasta easier to serve.
Sprinkle with fresh basil, parsley, Parmesan, or red pepper flakes.
Serve warm.
What to Serve With Cheesy Baked Rigatoni with Tomato Sauce
This baked pasta pairs beautifully with garlic bread, breadsticks, or crusty Italian bread.
A simple Caesar salad or garden salad adds a fresh contrast to the rich cheese and tomato sauce.
For vegetables, serve the rigatoni with roasted broccoli, asparagus, zucchini, green beans, or Brussels sprouts.
You can also pair it with sautéed spinach or a simple tomato and cucumber salad.
For a larger Italian-style dinner, serve it alongside meatballs, grilled chicken, or Italian sausage.
Tips for the Best Cheesy Baked Rigatoni with Tomato Sauce
Undercook the rigatoni slightly before baking.
Use plenty of sauce because pasta absorbs moisture in the oven.
Do not rinse the pasta after draining.
Use whole-milk ricotta for the creamiest texture.
Freshly shredded mozzarella usually melts better than pre-shredded cheese.
Allow the tomato sauce to simmer before assembling the casserole for deeper flavor.
Cover the dish during the first part of baking to prevent the top from drying out.
Remove the foil near the end so the cheese can brown.
Let the baked pasta rest before serving.
Taste the sauce before assembling and adjust the salt, herbs, or spice as needed.
