In a large 5 or 6 quart slow cooker add diced potatoes, minced garlic and broth. Cook on high for 3-4 hours until potatoes are very fork tender.
Once potatoes are done cooking, place slow cooker on warm setting and add in butter, sour cream and ½ cup of milk to start. Use a potato masher to mash potatoes until they reach your desired consistency. I happen to like my potatoes super creamy, so I mash them until they’re completely smooth.
If you want your potatoes creamier, add in ½ cup-1 cup more milk. Finally, a generous amount of salt and pepper, then mix again. Taste, and add more salt and pepper if necessary.
Transfer to a large warm casserole dish for serving, add a pat of butter, a sprinkle of fresh thyme, and a little freshly ground black pepper. Serves 10.
