Italian sausage rigatoni is a hearty, comforting pasta dish made with tender rigatoni, savory Italian sausage, and a rich tomato-based sauce. It’s easy enough for weeknights but satisfying enough for guests, delivering bold flavor in every bite.
Bring a large pot of well-salted water to a boil. Cook rigatoni until al dente according to package instructions. Reserve ½ cup pasta water, then drain and set aside.
Heat olive oil in a large skillet over medium heat. Add Italian sausage and cook, breaking it into small pieces, until browned and cooked through.
Add diced onion to the skillet and cook for 3–4 minutes, until softened. Stir in garlic and cook for 30 seconds until fragrant.
Sprinkle in Italian seasoning and red pepper flakes. Pour in marinara sauce and stir to combine. Simmer for 8–10 minutes.
For a creamy Italian sausage rigatoni, stir in heavy cream and simmer for 2–3 minutes until smooth.
Add cooked rigatoni to the sauce and toss to coat. Use reserved pasta water as needed to loosen the sauce.
Season with salt and black pepper to taste.
Remove from heat and garnish with Parmesan cheese and fresh herbs before serving.
Notes
Use fresh or refrigerated rigatoni for the best texture.
Sweet sausage offers balance, while spicy sausage adds heat.
For baked Italian sausage rigatoni, transfer to a baking dish, top with mozzarella, and bake at 375°F (190°C) for 15–20 minutes.
