Bring a 2-quart pot of water to a boil over medium-high heat. Add the fettuccine and cook until al dente, about 7–8 minutes. Drain and set aside.Pro Tip: Lightly toss the pasta with a little olive oil or 1 tablespoon of butter to prevent sticking.
In a 10-inch skillet, melt butter over medium heat. Season the chicken with salt and pepper, then cook for about 6 minutes, turning halfway through until browned and cooked through. Transfer to a plate and cover to keep warm.
In the same skillet, pour in the cream and lemon juice. Add 1 tablespoon of butter and stir until melted.
Reduce the heat to medium-low and simmer for about 3 minutes, stirring often as the sauce begins to thicken.
Stir in the Parmesan cheese and continue cooking for 8–10 minutes, stirring often, until the cheese melts, the sauce becomes rich and creamy, and it reduces by about one-third.
Return the cooked chicken to the skillet and stir to coat it in the Alfredo sauce.
Toss in the cooked fettuccine and stir until everything is evenly coated with the creamy sauce.
Transfer to a bowl and top with extra Parmesan cheese and chopped parsley, if desired.

Notes
Preparation Is Key: Take a moment to read through the entire recipe before starting. This Chicken Alfredo comes together quickly, so having ingredients measured and ready makes cooking easier.
Watch the Sauce: The sauce should simmer gently and thicken over 8–10 minutes, reducing by about one-third. Keep stirring often to help it stay smooth and prevent sticking or burning.
Get Creative with Add-Ins: Sautéed mushrooms, spinach, broccoli, or fresh herbs like oregano or thyme can be added to the sauce before you stir in the chicken and pasta.
Choose Homemade Sauce: Skip the jarred kind, our homemade Alfredo sauce gives you a rich, creamy flavor that’s hard to beat.
Lighter Sauce Option: Heavy cream creates the creamiest texture, but half and half can be used for a lighter version. Just know that a lower fat content will produce a thinner sauce.
