Creating Creamy Chicken Alfredo is a straightforward process that even novice cooks can master. Follow these steps to ensure a perfect dish every time:

1. Cook the Fettuccine:
   Begin by cooking the fettuccine in a large pot of boiling water following the package instructions. Once cooked, drain the pasta and set it aside.
2. Prepare the Chicken:
   In a skillet, melt the butter over medium heat. Add the diced chicken breasts, seasoning them with salt and pepper. Cook the chicken until it is no longer pink in the center, ensuring it is tender and juicy.
3. Sauté the Garlic:
   Add the minced garlic to the skillet and sauté for 1-2 minutes until fragrant. This step infuses the chicken with a delightful garlicky aroma.
4. Create the Alfredo Sauce:
   Pour the heavy cream into the skillet and bring it to a gentle simmer. Stir in the grated Parmesan cheese until it melts completely, creating a creamy and indulgent sauce.
5. Combine with Pasta:
   Toss the cooked fettuccine in the sauce until it is well-coated. Allow it to cook for another minute, ensuring the pasta absorbs the flavors of the sauce.
6. Serve and Garnish:
   Serve the Creamy Chicken Alfredo hot, garnished with fresh parsley if desired. The parsley adds a touch of color and a hint of freshness to the dish.
