In a large pot, bring well-salted water to a rolling boil. Add the fettuccine or linguine pasta and cook according to the package directions until al dente. Once cooked, drain the pasta in a colander and set aside while you prepare the sauce.
In a mixing bowl, add the sliced chicken breasts and sprinkle with the Cajun seasoning. Toss until all the chicken pieces are evenly coated with the spices for a flavorful kick.
Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the seasoned chicken slices to the skillet in a single layer. Cook for about 5-7 minutes, stirring occasionally until the chicken is golden brown and fully cooked through. Once done, remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the final tablespoon of olive oil. Once heated, incorporate the finely minced garlic and sliced bell pepper into the skillet. Sauté for 3-4 minutes, stirring frequently until the vegetables are tender and fragrant.
Gradually pour in the chicken broth, stirring to combine, and bring to a gentle simmer. Reduce the heat to medium-low, then add the heavy cream. Mix well and allow it to cook for 2-3 minutes until the sauce thickens slightly, creating a rich and creamy base.
Transfer the cooked pasta and sautéed chicken back into the skillet. Gently toss everything together, ensuring each piece of pasta is coated with the creamy Cajun sauce. Stir in the freshly grated Parmesan cheese, mixing well to blend the flavors. Taste and adjust seasoning with salt and black pepper as needed.
Remove the skillet from the heat and allow it to rest for a minute to let the sauce thicken further. Serve the dish hot, garnished generously with freshly chopped parsley for a pop of color and freshness.
