Roast garlic (approx 40 mins)
Spray the inside of a three-quart slow cooker with cooking spray.
Add the potatoes, thyme, roasted garlic cloves, butter, salt, pepper, and chicken broth.
Cover and allow the slow cooker to cook for 4-5 hours on high or 7-8 hours on the low setting. Stir occasionally.
Add the heavy cream to preference. Start with ⅓ cup and if you want the potatoes to be more creamy, add the full ½ cup.
Mash for more rustic potatoes or use a hand mixer to blend the potatoes. Careful if blending, mix on the slow speed and don't let the blades get too close to the base of the crockpot.
Season with additional salt and pepper to taste.
Sprinkle the parsley and fold in before serving.
