Instructions
Cook the Pasta
Bring a large pot of salted water to a boil. Add 1 pound rigatoni and cook until al dente, following package instructions.
Drain and set aside.
Make the Sauce
Heat 1 tablespoon extra virgin olive oil in a large skillet over medium heat.
Add 1 small yellow onion, diced, and sauté until softened, about 5 minutes. Stir in 3 garlic cloves, minced, and cook for 1 minute more.
Add 1 pound ground Italian sausage and cook until browned, breaking it into small pieces with a spoon. Stir in 1/2 teaspoon crushed red pepper flakes if using.
Pour in 1 can (28 ounces) crushed tomatoes and 1/2 cup tomato sauce. Add 1 teaspoon dried oregano, 1 teaspoon dried basil, and 1/4 teaspoon Calabrian chili paste (optional). Season with kosher salt and freshly ground black pepper to taste.
Simmer for 10-15 minutes, stirring occasionally. Remove from heat and stir in 1/4 cup fresh basil leaves, chopped.
Combine Pasta and Sauce
Preheat your oven to 375°F (190°C).
In a large bowl, combine the cooked rigatoni with the sauce. Add 1/2 cup whole milk ricotta cheese, 1 cup shredded mozzarella cheese, and 1/2 cup grated Parmesan cheese. Mix until well combined.
Assemble and Bake
Transfer the mixture to a greased 9x13-inch baking dish.
Top with the remaining 1 cup shredded mozzarella cheese and 1/2 cup grated Parmesan cheese.
Bake uncovered for 20-25 minutes, or until the cheese is melted and golden brown.
Garnish and Serve
Let the dish rest for 5 minutes before serving. Garnish with extra fresh basil leaves and enjoy!
Notes
Save the Pasta Water: Reserve a quarter cup of pasta water to loosen the sauce mixture if it feels too thick.Layer for Even Distribution: For the best texture, layer half of the pasta with sauce and cheese, then add the rest of the pasta and repeat.Avoid Overcooking: Undercook the pasta slightly—by about a minute from package directions—to prevent mushy baked pasta.Cover with Foil First: For a perfectly gooey cheese layer without burning, bake the dish covered with aluminum foil for the first 15-20 minutes, then uncover to let the top turn golden brown.
