In a large skillet, heat the vegetable or canola oil over medium heat. Add the bite-sized chicken pieces and season with a sprinkle of salt and pepper. Cook for about 5-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the sliced mushrooms. Sauté them for about 4-5 minutes until they are soft and have released their moisture. Add the minced garlic and cook for an additional minute, stirring frequently to prevent burning.
Sprinkle the all-purpose flour over the mushrooms and garlic, stirring to coat everything evenly. Gradually pour in the chicken broth while continuing to stir. Bring the mixture to a simmer, allowing it to thicken slightly. Then, add the evaporated milk and whipped cream cheese, stirring until the cheese is melted and the sauce is creamy.
Return the cooked chicken to the skillet and stir it into the sauce. Add the freshly grated Parmesan cheese and mix until it’s fully incorporated. Season with freshly ground black pepper to taste.
Finally, add the hot cooked fettuccine to the skillet. Gently toss everything together until the pasta is well-coated with the creamy sauce.
Divide the Chicken Mushroom Fettuccine among serving plates. If desired, garnish with chopped fresh Italian parsley for a pop of color and added flavor. Serve immediately and enjoy your homemade masterpiece!
