With a creamy Alfredo sauce made from heavy cream, cream cheese, and Parmesan, you get all the indulgence without any of the guilt. Plus, the dish is filled with protein from the chicken and healthy fats from the cheese and cream—perfect for anyone following a ketogenic lifestyle.

What Type of Chicken to Use?

In this recipe, I am using raw cubed chicken breast and frying them directly into the pan. But you can also use cooked cubed or shredded chicken. (if you ask me I prefer the fried version).

And more thing, use chicken thighs if you don’t have chicken breasts in hand.
