Begin by cooking the fettuccine pasta according to the package instructions. Once al dente, drain and set aside, reserving 1/2 cup of the pasta water.
In a large skillet, heat the olive oil over medium heat. Add the diced chicken breasts and season with salt, pepper, and Italian seasoning. Cook for about 5-7 minutes or until the chicken is cooked through and golden brown.
Add the minced garlic to the skillet, cooking for an additional 1-2 minutes until fragrant, being careful not to burn the garlic.
Reduce the heat to low and pour in the heavy cream, stirring gently to combine with the chicken and garlic.
Gradually add the grated Parmesan cheese, stirring until melted and smooth. If the sauce is too thick, slowly add in a bit of the reserved pasta water until the desired consistency is reached.
Toss the cooked fettuccine into the skillet, mixing until the pasta is well-coated with the creamy garlic Parmesan sauce. Adjust seasoning if necessary.
Remove from heat. Serve immediately, garnishing with freshly chopped parsley on top for a flavorful finish.
Notes
Arrange the pasta in a large serving bowl, twirling the fettuccine with a fork for an elegant look. Top with extra Parmesan cheese and a sprinkle of freshly chopped parsley for color.
