It is the same recipe but with chicken added to the recipe. This is a delicious variation if you want to add more protein. You can prepare chicken and then cut up and combine with the sauce. Another option is to use leftover chicken or rotisserie chicken. Anytime I need a quick meal, the easiest option is to shred rotisserie chicken. Dinner is so fast and easy with this effortless option. The chicken will just be added when you add the other carbonara ingredients together.
