Add the chicken breasts and frozen mixed vegetables to your crockpot.
Season the chicken and vegetables with salt, pepper, garlic powder, onion powder, and Kinder’s Buttery Garlic & Herb Seasoning.
Pour in the cream of chicken soup, add the cream cheese block, and pour in the chicken broth.
Cover and cook on HIGH for 3 hours, until the chicken is fully cooked and tender.
Shred the chicken directly in the crockpot and stir until the cream cheese is fully incorporated into the sauce.
Add the cooked pasta, shredded cheddar cheese, sour cream, and heavy cream to the crockpot.
Stir everything together until the pasta, chicken, vegetables, cheese, sour cream, and heavy cream are fully combined and smooth.
Let the pasta sit for 5 to 10 minutes to thicken, then serve hot and enjoy.
