Creating Creamy Garlic Parmesan Chicken Pasta is simple if you follow these steps:

1. Cook the Pasta: In a large pot of salted boiling water, cook the fettuccine according to package instructions until al dente. Drain and set aside.
2. Prepare the Chicken: Season the chicken breasts with salt and pepper. In a large skillet, melt 2 tablespoons of butter over medium heat.
3. Cook the Chicken: Add the seasoned chicken to the skillet and cook for about 6-7 minutes on each side, or until cooked through and no longer pink in the center. Remove from the skillet and set aside to rest.
4. Sauté the Garlic: In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
5. Make the Sauce: Pour in the heavy cream and bring to a simmer. Stir in the grated Parmesan cheese and Italian seasoning. Allow the sauce to thicken for about 3-4 minutes.
6. Combine Pasta and Chicken: Slice the cooked chicken into strips and add it to the sauce, along with the drained pasta. Toss well to coat everything in the creamy sauce.
7. Season to Taste: Taste the pasta and adjust seasoning with more salt and pepper if needed.
8. Garnish and Serve: Serve hot, garnished with chopped fresh parsley for added color and flavor.

These steps will ensure that you create a deliciously creamy and flavorful dish that everyone will love.
