Place the chicken breasts in an even layer in the bottom of the crockpot.
In a medium bowl, whisk together the heavy cream, chicken broth, minced garlic, grated Parmesan, Italian seasoning, and a pinch of salt and pepper until combined.
Pour the sauce evenly over the chicken, making sure the breasts are mostly covered.
Cooking
Cover and cook on LOW for 6–7 hours, or until the chicken reaches 165°F and is tender enough to shred.
Remove the lid and shred the chicken directly in the sauce with two forks. Stir the shredded chicken into the sauce so it absorbs the flavors. Taste and adjust seasoning with salt or pepper as needed.
Serve hot, garnished with chopped parsley.
Notes
Best served over buttered egg noodles, fettuccine, mashed potatoes, or with steamed green beans. For leftovers, serve in sandwiches or as a pasta bake.
