Spray the inside of the crockpot with non-stick cooking spray.
Add the chicken breast and garlic.
Soften the butter and cream cheese in the microwave, then whisk until smooth.
Whisk in the cream of chicken soup (do not dilute).
Add the Italian dressing mix and chicken stock, whisking until well mixed.
Pour over the chicken breasts, cover, and cook on low for 6 to 8 hours.
Optionally, 30 minutes before the cooking time is finished, shred the chicken breasts with two forks and continue to cook in the sauce.
Just before the chicken is done, cook the angel hair pasta, drain, and serve the chicken over the pasta.
