Season the chicken with salt, pepper, paprika, garlic powder, and onion powder. Heat olive oil in a large pan over medium heat and cook the chicken until golden and fully cooked. Remove and set aside.
In the same pan, melt the butter and sauté the garlic for about 30 seconds until fragrant.
Add the fettuccine and pour in the chicken broth and water. Bring to a simmer and cook for 10–15 minutes, stirring occasionally, until the pasta is tender and most of the liquid is absorbed.
Stir in the heavy cream, Parmesan cheese, Italian seasoning, red pepper flakes, salt, and pepper. Let simmer until the sauce thickens and becomes creamy.
Slice the chicken and place on top. Garnish with fresh parsley and extra Parmesan, then enjoy!
