About the Ingredients

Sweet Italian sausage adds savory flavor and richness while pairing beautifully with the creamy garlic Alfredo sauce.
Roasted Garlic
Roasted garlic brings a mellow, slightly sweet flavor that makes the Alfredo sauce especially flavorful.
Heavy Cream
Heavy cream creates the rich and silky base of the homemade Alfredo sauce.
Parmesan Cheese
Freshly grated Parmesan melts into the sauce for a savory, cheesy flavor and adds a delicious golden topping when baked.
Tips & Tricks
Cook Pasta Al Dente
Cook the rigatoni slightly firm because it will continue cooking while the dish bakes in the oven.
Do Not Boil the Alfredo Sauce
Heat the cream gently without boiling to help maintain a smooth and creamy sauce.
Use Freshly Grated Parmesan
Freshly grated Parmesan melts more smoothly and creates a better texture in the Alfredo sauce.
Pro Tips
- Roast the garlic ahead of time to make preparation easier.
- Reserve a little pasta water in case the sauce needs thinning before baking.
- Let the baked rigatoni rest for a few minutes before serving so the sauce can settle.
Step-by-Step Instructions
Prepare the Baking Dish
Preheat the oven to 350°F and prepare an 8×8-inch baking dish with cooking spray.
Cook the Rigatoni
Cook the rigatoni in generously salted water according to package directions until al dente. Drain and toss with a little olive oil to prevent sticking.
Cook the Sausage
Sauté the chopped onion and minced garlic in olive oil until translucent. Add the Italian sausage and cook thoroughly. Stir in basil, salt, and pepper, then set aside.
Prepare the Roasted Garlic Alfredo Sauce
Squeeze the roasted garlic cloves from their skins and mash them with a fork. Melt butter in a saucepan, add heavy cream and roasted garlic, and heat until very warm without boiling.
Finish the Alfredo Sauce
Lower the heat and whisk in Parmesan, salt, and pepper until the cheese melts. Mix flour with heavy cream separately, then stir it into the sauce and heat until thickened.
Combine the Ingredients
Pour the Alfredo sauce over the cooked sausage mixture and stir until well coated. Add the rigatoni and mix thoroughly.
Bake the Rigatoni
Transfer the mixture to the prepared baking dish and sprinkle shaved Parmesan over the top. Bake for about 30 minutes until bubbly and lightly browned.
Serve
Allow the pasta to cool slightly before serving. Garnish with additional basil or Parmesan if desired.
