Making Delicious Creamy Cajun Chicken Pasta can be seamless by following these simple steps:

1. Cook the Pasta: Boil a large pot of salted water and cook the fettuccine according to package directions. Drain and set aside.

2. Season the Chicken: In a mixing bowl, toss the chicken strips with the Cajun seasoning until evenly coated.

3. Sauté the Chicken: Heat olive oil in a large skillet over medium-high heat. Add the seasoned chicken and sauté until cooked through and no longer pink, about 5-7 minutes. Remove the chicken from the pan and set aside.

4. Sauté Vegetables: In the same skillet, add the sliced bell pepper and chopped onion. Sauté for 3-4 minutes until softened.

5. Add Garlic: Stir in the minced garlic and cook for an additional minute until fragrant.

6. Create the Sauce: Pour the heavy cream and chicken broth into the skillet with the vegetables. Cook on medium heat until slightly thickened.

7. Mix in Cheese: Stir in the grated Parmesan and continue to cook until melted and creamy. Adjust seasoning with salt and pepper as needed.

8. Combine with Chicken and Pasta: Return the chicken to the sauce, then add the cooked fettuccine. Toss until everything is well combined and heated through.

9. Garnish and Serve: Remove from heat, garnish with chopped green onions, and serve hot.
