Season the chicken thighs with salt, pepper, garlic powder, and onion powder.
In a large skillet, heat the olive oil over medium-high heat. Add the chicken thighs and sear for about 4-5 minutes on each side until golden brown. Remove from skillet and set aside.
In the same skillet, add the halved baby potatoes and minced garlic. Sauté for 2-3 minutes until the potatoes are slightly golden.
Transfer the potatoes to a slow cooker. Pour in the chicken broth, then place the seared chicken thighs on top.
In a bowl, whisk together the heavy cream, Parmesan cheese, and dried Italian herbs. Pour this mixture over the chicken and potatoes in the slow cooker.
Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
Before serving, sprinkle with fresh parsley for garnish.
