Place the chicken breasts in a single layer at the bottom of the crockpot.
Scatter the chopped onion, minced garlic, and sun-dried tomatoes evenly over the chicken.
Pour in the chicken broth and add the cream or dollops of cream cheese. Season with salt and pepper.
Cooking
Cover and cook on low for 6–8 hours or on high for 3–4 hours, until the chicken is fully cooked and tender.
Remove the lid, shred the chicken directly in the crockpot using two forks, and stir so the sauce coats the shredded meat.
Taste and adjust seasoning. Garnish with torn fresh basil before serving.
Notes
Refrigerator: Store cooled leftovers for up to 3–4 days. Reheat gently on the stovetop or microwave. Freezer: Freeze up to 3 months; stir in milk when reheating if the sauce separates.
