Prepare the Chicken: Place 4 boneless, skinless chicken breasts (about 1.5 lbs) at the bottom of your slow cooker. Ensure they are evenly spread out for optimal cooking.
Add Butter: Cut ¼ cup butter into small pieces and distribute them on top of the chicken breasts. This will melt and soak into the chicken during cooking.
Mix the Sauce: In a medium bowl, combine 1 packet of Italian dressing mix, 1 can (10.75 oz) condensed golden mushroom soup, and ½ cup chicken broth. Stir until well mixed.
Pour Over Chicken: Carefully pour the sauce mixture over the chicken breasts, ensuring they are well covered.
Slow Cook: Cover the crockpot and cook on low for 6-8 hours or high for 3-4 hours, until the chicken is tender and easily shredded with a fork.
Add Cream Cheese: About 30 minutes before you’re ready to serve, add 4 oz cream cheese (cut into cubes) to the crockpot and stir well until melted and combined.
Cook the Pasta: In the last 15-20 minutes of cooking, prepare 1 lb angel hair pasta according to package instructions. Drain and set aside.
Serve: Once the chicken is fully cooked and the cream cheese has melted, serve the chicken mixture over the pasta, spooning extra sauce over the top for added flavor.
