# How to Make It:
01 - Preheat oven to 375°F. Grease a 9-inch springform pan with olive oil and line the base with parchment paper.
02 - Bring a large pot of salted water to a boil. Cook rigatoni until very al dente, about 2 minutes less than the package instructions. Drain and toss with 1 tablespoon olive oil. Set aside.
03 - Heat 2 tablespoons olive oil in a saucepan over medium heat. Sauté onion until translucent, 3–4 minutes. Add garlic and cook 1 minute. Stir in crushed tomatoes, tomato paste, oregano, basil, sugar, salt, and pepper. Simmer, stirring occasionally, for 15–20 minutes. Adjust seasoning to taste.
04 - In a mixing bowl, combine ricotta, 1 cup shredded mozzarella, Parmesan, egg, parsley, salt, and black pepper. Stir until smooth.
05 - Stand cooked rigatoni upright, tightly packed, in the prepared pan. Using a piping bag or small spoon, fill each pasta tube with cheese filling.
06 - Pour tomato sauce evenly over the filled pasta, allowing it to seep down between the noodles. Sprinkle the remaining 1 cup mozzarella over the top.
07 - Cover loosely with foil and bake for 30 minutes. Remove foil and continue baking for 15 minutes, until the cheese is golden and bubbling.
08 - Let stand for 10 minutes before releasing the springform pan. Garnish with extra parsley and grated Parmesan. Slice and serve.
