Ingredients

  • 5 pounds gold potatoes, diced (peeled or unpeeled, your choice)
  • 4 cloves garlic, minced
  • 1 ½ to 2 cups whole milk (or half and half or heavy cream), divided
  • cup softened butter (or vegan butter)
  • ½ cup sour cream or whole-milk plain greek yogurt
  • Kosher salt and freshly ground black pepper, to taste
  • To garnish:
  • Extra butter
  • Fresh thyme spigs
  • Freshly ground black pepper

Instructions

  • In a large 5 or 6 quart slow cooker add diced potatoes, minced garlic and 1 1/2 cups of milk. Cook on high for 3 to 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 1/2 cup of milk to start. MAKE SURE ALL INGREDIENTS ARE AT ROOM TEMPERATURE OR WARMED! 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! You can also use an electric hand mixer if you prefer. 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.

Notes

To make vegan: Use a dairy-free milk (I recommend unsweetened cashew milk for the best flavor) and dairy-free butter. I would skip the sour cream and simply add more vegan butter or milk.
If you don't like potato skins, feel free to peel your potatoes before dicing and placing in the slow cooker. They're delicious!
If you're keeping the potatoes warm in your slow cooker, you may need to add more milk before serving to keep their silky smooth texture. Mashed potatoes can be kept warm in the slow cooker for up to 3 hours.
