Place chicken thighs in the 6-8 Quart Crock Pot
Sprinkle with dressing mix and pour chicken broth over chicken
Cover and cook on low for 6 to 8 hours
Remove chicken to a plate and shred with two forks
Add cream cheese to broth in the slow cooker
Let sit with lid on for about 10 minutes
Use a whisk to make a liquid out of cream cheese and broth**
** This will be very runny consistency, but once the chicken and pasta are added and it's sat for about 30 minutes you'll have the perfect creamy crock pot fettuccine alfredo sauce there is - guaranteed!
Add the cooked al dente pasta to the Crock Pot and shredded chicken to the Crock Pot
Leave uncovered and stir until pasta is coated and Crock Pot alfredo sauce is at desired consistency
