In a small bowl, combine the lemon pepper, garlic powder, Italian seasoning, red pepper flakes, and parsley. Set aside.
In a large pot over medium heat, add in the olive oil. Once hot, slowly add in the chicken a few at a time until they eventually lay in an even layer into the pan. Cook until chicken is no longer pink, about 7-10 minutes.
Once the chicken is cooked, stir in the lemon pepper blend. Cook for another minute or until all of the chicken covered. Season with salt and pepper.
Add in the flour and cook for another minute. The chicken will become a thick mixture.
Slowly stir in the chicken stock and butter. Mix until it becomes a thin, even consistency.
Carefully place the pasta over the chicken, making sure each pasta is coated with the stock. Cover and cook for 10-12 minutes, stirring often, until pasta is al dente. I recommend using a fork to help separate the pasta from one another. If liquid evaporates before the pasta is al dente, add ½ cup more stock in at a time.
Reduce the heat to medium-low. Uncover and stir in the heavy cream. Cook for another 3-5 minutes or until pasta is creamy.
Garnish with cheese and serve.
