Prepare the Pasta: Bring a large pot of salted water to a boil. Add the fettuccine or penne pasta and cook according to package instructions until al dente. Drain and set aside, reserving 1 cup of pasta water.
Cook the Chicken: While the pasta is cooking, season the chicken breasts with salt, pepper, and Italian seasoning. Heat 2 tablespoons of butter in a skillet over medium-high heat. Add the chicken and cook for about 5-7 minutes on each side, or until the chicken is cooked through and no longer pink in the center. Remove from the skillet and let rest before slicing into strips.
Make the Sauce: In the same skillet, reduce heat to medium and add the remaining 2 tablespoons of butter. Once melted, add minced garlic and sauté for 1-2 minutes until fragrant but not browned.
Combine the Ingredients: Slowly pour in the heavy cream, stirring continuously. Gradually add the grated Parmesan cheese while mixing to create a creamy sauce. If the sauce is too thick, add a little reserved pasta water until desired consistency is achieved.
Combine Pasta and Chicken: Add the cooked pasta to the sauce, tossing to coat evenly. Add in the sliced chicken and mix well. Season with additional salt and pepper to taste.
Serve: Once everything is well combined and heated through, plate the creamy garlic Parmesan chicken pasta.
Notes
Garnish with fresh parsley and extra Parmesan cheese for added flavor.
