Creating Creamy Cajun Shrimp Pasta is a straightforward process. Follow these steps for a successful dish:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside.

1. Prepare the Shrimp: In a medium bowl, toss the shrimp with Cajun seasoning, ensuring they are evenly coated.

1. Sauté the Shrimp: Heat olive oil in a large skillet over medium heat. Add the seasoned shrimp and cook for 2-3 minutes on each side until pink and opaque. Remove the shrimp from the skillet and set aside.

1. Sauté the Garlic: In the same skillet, add minced garlic. Sauté for about 1 minute until fragrant but not browned.

1. Make the Sauce: Pour in the chicken broth and bring it to a simmer. Add the diced tomatoes and heavy cream. Stir to combine and let it simmer for 3-5 minutes.

1. Add Cheese: Gradually stir in the grated Parmesan cheese, allowing it to melt into the sauce. Adjust the seasoning with salt and pepper.

1. Combine Pasta and Shrimp: Add the cooked pasta and shrimp back into the skillet. Toss well to coat everything in the creamy sauce.

1. Garnish and Serve: Sprinkle with chopped green onions and parsley before serving.
