Ingredients
-
12 ounces pasta (penne, fettuccine, or linguine)
-
1 pound shrimp, peeled and deveined
-
8 ounces smoked sausage (Andouille preferred), sliced
-
2 tablespoons olive oil
-
2 tablespoons butter
-
1 small onion, finely chopped
-
4 cloves garlic, minced
-
1½ cups heavy cream
-
½ cup chicken broth
-
1 cup grated Parmesan cheese
-
2 teaspoons Cajun seasoning (adjust to taste)
-
½ teaspoon paprika
-
½ teaspoon black pepper
-
¼ teaspoon red pepper flakes (optional)
-
Salt, to taste
-
Fresh parsley, chopped (for garnish)
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil and cook the pasta according to package instructions until al dente. Reserve ½ cup of the pasta cooking water, then drain the pasta and set it aside. Cooking the pasta just until tender ensures it won’t become mushy when tossed with the sauce later.
Step 2: Season and Cook the Shrimp
Pat the shrimp dry with paper towels and season them lightly with Cajun seasoning and black pepper. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for about 2 minutes per side, just until they turn pink and opaque. Remove the shrimp from the skillet and set aside. Be careful not to overcook them, as shrimp cook very quickly and can become rubbery.
Step 3: Brown the Sausage
In the same skillet, add the sliced sausage. Cook for 4–5 minutes, stirring occasionally, until the sausage is browned and slightly crispy on the edges. Browning the sausage releases smoky flavor into the pan, which becomes the base of the sauce. Remove the sausage and set it aside with the shrimp.
Step 4: Build the Flavor Base
Reduce the heat to medium and add butter to the skillet. Once melted, add the chopped onion and cook for 3–4 minutes until soft and translucent. Stir in the minced garlic and cook for about 30 seconds until fragrant. This step creates a rich, aromatic base that supports the bold Cajun spices.
Step 5: Make the Creamy Cajun Sauce
Pour in the chicken broth and scrape the bottom of the skillet to release any browned bits. Slowly add the heavy cream, stirring constantly. Sprinkle in Cajun seasoning, paprika, black pepper, and red pepper flakes if using. Let the sauce simmer gently for 5–7 minutes, stirring occasionally, until slightly thickened.
Stir in the grated Parmesan cheese and continue stirring until the cheese melts smoothly into the sauce. Taste and adjust seasoning with salt if needed. The sauce should be creamy, well-seasoned, and lightly spicy.
Step 6: Combine Everything
Add the cooked pasta to the skillet and toss to coat it evenly with the sauce. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it. Return the cooked shrimp and sausage to the skillet and gently stir until everything is warmed through and evenly combined.
Step 7: Serve
Remove the skillet from heat and garnish the pasta with freshly chopped parsley and extra Parmesan cheese if desired. Serve hot and enjoy immediately. This dish pairs well with garlic bread or a simple green salad to balance the richness of the sauce.
