Rigatoni al Forno is classic baked pasta made simple for weeknights. Saucy tomato-beef rigatoni bakes under melty mozzarella for an easy family favorite.
Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish.
Bring a large pot of salted water to a boil. Cook rigatoni 2 minutes shy of al dente so it can finish in the oven. Drain and set aside.
In a large skillet, warm olive oil over medium heat. Add the diced onion and a pinch of salt. Cook until soft. Stir in the Italian seasoning and garlic and cook for 1 minute until fragrant.
Add ground beef and cook, breaking it up, until browned. Drain excess fat if needed.
Stir in the crushed tomatoes and tomato sauce. Simmer for 5 to 7 minutes until lightly thickened. Taste and adjust salt and pepper.
Toss the cooked rigatoni with about 70 to 80% of the sauce until well coated. Spread into the prepared baking dish. Spoon the remaining sauce over the top.
Sprinkle evenly with shredded mozzarella.
Cover with foil and bake for 20 minutes. Uncover and bake 5 to 10 minutes more until bubbling with light golden spots.
Let it sit for 10 minutes so the sauce settles and scoops hold together. Garnish with fresh basil, if desired.
Notes
Make sure to not overcook the pasta so it finishes perfectly in the oven.

Store leftovers in an airtight container for up to 4 days.
