Spray a 5 to 6 quart slow cooker with nonstick cooking spray. Place the chicken breasts in the bottom of the slow cooker. Top with the butter. Pour the can of Progresso Creamy Parmesan Basil Recipe Starter over the top of the chicken. Cover and cook on low until the chicken shreds easily, about 4-6 hours.
Using 2 forks, shred the chicken in the slow cooker. Cut the cream cheese into cubes and add to the chicken. Continue cooking on low until the cream cheese has melted, about 30 minutes. Stir to combine.
While the cream cheese is melting, bring a large pot of salted water to a boil. Cook the noodles until al dente. Drain and reserve.
Serve the sauce over the prepared pasta. Top with shredded fresh basil.
