In a large heavy-bottomed pot, add chopped rotisserie chicken, condensed cream of chicken soup, 6 cups of chicken broth, whole milk, sliced celery, carrots, ranch dressing mix, crumbled bacon, and softened cream cheese. Stir until well combined.
02 -
Set the pot over medium-high heat and bring the mixture just to a rolling boil.
03 -
Immediately lower the heat to medium-low. Simmer, stirring occasionally, for 20 to 25 minutes to allow vegetables to soften and flavors to develop.
04 -
Add thin spaghetti to the soup, gently stirring to help noodles separate as they soften. Stir in shredded cheddar cheese until melted and evenly distributed.
05 -
Continue simmering until spaghetti is just al dente, stirring often to prevent sticking or clumping.
06 -
If a thinner consistency is desired, gradually stir in the remaining 1 cup chicken broth.
07 -
Remove from heat and serve immediately while hot.
