Creating Creamy Cajun Chicken Pasta is a delightful experience. Follow these simple steps for an incredible meal:

1. Cook the Pasta: In a large pot of boiling salted water, cook the fettuccine according to the package instructions until al dente. Drain and set aside.
2. Season the Chicken: Sprinkle Cajun seasoning evenly over the sliced chicken, coating it well.
3. Heat Olive Oil: In a large skillet over medium heat, heat the olive oil. Add the seasoned chicken strips and cook until golden brown and cooked through, approximately 5-7 minutes. Remove the chicken from the skillet and set aside.
4. Sauté Onions and Garlic: In the same skillet, add the diced onion and sauté until translucent, about 3 minutes. Add minced garlic and cook for an additional 1 minute.
5. Add Bell Pepper: Toss in the sliced red bell pepper and sauté until softened, around 3-4 minutes.
6. Create the Sauce: Pour in the chicken broth and scrape the bottom of the skillet to deglaze. Bring it to a simmer, then lower the heat and stir in the heavy cream.
7. Add Cheese: Gradually add the grated Parmesan cheese, stirring until the sauce is smooth and creamy. Adjust seasoning with salt and pepper to taste.
8. Combine with Pasta: Add the cooked fettuccine and the sautéed chicken back into the skillet. Toss everything together until the pasta is well coated with the sauce.
9. Simmer to Thicken: Allow everything to simmer lightly for about 2-3 minutes, letting the flavors meld together.
10. Garnish and Serve: Remove from heat, garnish with fresh parsley, and serve immediately.
