Creating Shrimp & Crab Pasta with Creamy Cajun Sauce is simple when following these easy steps:

1. Boil the Pasta: In a large pot, bring salted water to a boil. Add the linguine or fettuccine and cook according to package instructions until al dente. Drain and set aside.
2. Sauté Seafood: In a large skillet over medium heat, add olive oil and butter. Once melted, add minced garlic and sauté for about 1 minute until fragrant.
3. Cook Shrimp: Add the shrimp to the skillet, seasoning them with Cajun seasoning, smoked paprika, salt, and black pepper. Cook for 3-4 minutes, stirring frequently, until shrimp turn pink and opaque.
4. Add Crab Meat: Gently fold in the crab meat and cook for an additional 2 minutes until warmed through.
5. Make the Sauce: Pour in the heavy cream and chicken broth. Increase heat to bring the mixture to a simmer, allowing it to thicken for about 5 minutes.
6. Combine Pasta: Add the cooked pasta to the skillet, tossing to coat it with the creamy Cajun sauce and seafood mixture thoroughly.
7. Garnish the Dish: Remove from heat and sprinkle with chopped green onions and fresh parsley for a pop of color and flavor.
8. Serve: Divide the pasta among bowls and top with grated Parmesan cheese, if desired.
