Follow these simple steps to prepare your One-Pan Chicken Alfredo:

1. Heat the Olive Oil: In a large skillet or frying pan, heat the olive oil over medium-high heat.
2. Cook the Chicken: Season the chicken strips with salt and pepper. Add them to the skillet and cook until they are golden brown and cooked through, about 5-7 minutes. Remove the chicken from the pan and set aside.
3. Sauté the Garlic: In the same skillet, add the minced garlic. Sauté for about 1 minute, or until fragrant. Be careful not to burn the garlic.
4. Add Broth and Cream: Pour in the chicken broth and heavy cream. Stir to combine, scraping up any browned bits from the bottom of the pan.
5. Cook the Pasta: Add the fettuccine to the pan, ensuring it is submerged in the liquid. Bring the mixture to a boil, then reduce the heat to medium-low. Cover the pan and let it simmer for about 10-12 minutes, or until the pasta is tender, stirring occasionally.
6. Incorporate the Parmesan Cheese: Once the pasta is cooked, stir in the Parmesan cheese until it is fully melted and the sauce is creamy.
7. Return the Chicken: Add the cooked chicken back into the pan. Stir well to coat the chicken with the Alfredo sauce.
8. Garnish and Serve: Remove the pan from the heat. Garnish with chopped parsley and red pepper flakes, if desired. Serve immediately.
