Prepare the Chicken:
Place the chicken breasts or thighs in the crockpot. Season with salt, pepper, oregano, basil, and thyme.
Make the Sauce:
In a saucepan, melt butter over medium heat. Add minced garlic and sauté for 1-2 minutes until fragrant. Whisk in heavy cream, Parmesan cheese, salt, and pepper. Simmer for 5 minutes until thickened.
Combine in Crockpot:
Pour the sauce over the chicken in the crockpot. Cover and cook on low for 4-6 hours, or until the chicken is tender.
Cook the Pasta:
In the last 30 minutes of cooking, add the pasta to the crockpot. Stir to combine, ensuring the pasta is fully submerged in the sauce.
Cook until the pasta is tender.
Serve:
Shred the chicken if desired, and stir everything together. Serve hot, garnished with fresh parsley, alongside garlic bread if desired.
