Ingredients

Why this recipe works

The method here is designed to build layers of flavor quickly. Browning the andouille sausage first renders its fat and creates crispy edges, which not only adds texture but also infuses the butter with a deep, smoky taste. The shrimp are then seared in the same pan, picking up those browned bits and taking on a beautiful pink color. This step-by-step approach ensures every component is cooked perfectly and contributes to the overall richness of the dish.

The sauce is a simple combination of cream, broth, and Cajun seasoning, but the technique makes it exceptional. Simmering the cream and broth together allows the sauce to thicken and become glossy, while the garlic and seasoning bloom in the hot pan drippings.

Adding the Parmesan at the end gives the sauce a savory, nutty depth and helps it cling to the pasta. Tossing the rigatoni directly into the sauce ensures every tube is coated inside and out, creating a cohesive, satisfying dish.

Notes and substitutions

Andouille sausage is a smoked, garlicky pork sausage that's a staple of Cajun cooking. It's widely available in American supermarkets, usually in the refrigerated section near other smoked sausages. If you can't find it, a good-quality smoked sausage or kielbasa works well as a substitute. The key is to slice it into coins and brown them until crisp—this brings out their smoky flavor and adds texture to the dish.

When it comes to shrimp, look for jumbo or extra-large shrimp that are peeled and deveined. You can buy them fresh or frozen; if frozen, thaw them overnight in the refrigerator. The shrimp cook quickly, so be careful not to overcook them—they're done when they turn pink and opaque.

For the pasta, rigatoni is ideal because its ridges and wide tubes catch the sauce beautifully, but penne or ziti also work. Use a good-quality Parmesan and grate it yourself for the best flavor and melting.

• andouille sausage: Smoked sausage or kielbasa, sliced, for a milder smoky flavor.
• jumbo shrimp: Chicken breast, cut into bite-sized pieces, cooked until no longer pink (165°F/74°C).
• heavy cream: Half-and-half mixed with 1 tbsp butter for a lighter sauce (sauce will be slightly thinner).
• rigatoni: Penne, ziti, or cavatappi—any short pasta with ridges works well.
