Wash the baby red potatoes and cut them into quarters. Spread them evenly at the bottom of your Crock-Pot.
Pat the chicken breasts dry. Sprinkle Italian seasoning, salt, and pepper on both sides for even flavor.
In a small bowl, mix the melted butter (or avocado oil), lemon juice, and minced garlic along with a pinch more salt and pepper.
Place the chicken breasts on top of the potatoes in the Crock-Pot. Pour the chicken broth over the potatoes, then drizzle the marinade evenly over the chicken and potatoes.
Cover your Crock-Pot and cook on high for about 3 hours or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender. Garnish with fresh parsley when serving.
