These creamy slow cooker garlic mashed potatoes are make-ahead magic, perfect for holidays and busy weeknights. They cook low and slow in cream and butter, absorbing all that flavor as they go, resulting in a silky-smooth texture that stovetop methods just can’t match.

Ingredients

Scale
  • 5 pounds Yukon Gold potatoes, peeled and cut into 2-inch chunks
  • 6 cloves garlic, peeled and smashed
  • 1 cup chicken or vegetable broth
  • 1 teaspoon salt, plus more to taste
  • ½ teaspoon black pepper
  • 4 ounces cream cheese, softened and cut into cubes
  • ½ cup unsalted butter, cut into pieces
  • ¾ cup whole milk or heavy cream, warmed
  • ¼ cup sour cream
  • 2 tablespoons fresh chives, chopped (for garnish)

Instructions

  1. Prep the potatoes (10 minutes): Peel your potatoes and cut them into even 2-inch chunks. Rinse the chunks in cold water to remove excess starch.
  2. Layer in the slow cooker (5 minutes): Place the potato chunks in your slow cooker. Tuck the smashed garlic cloves in among the potatoes. Pour in the chicken broth and season with salt and pepper. Give everything a gentle stir.
  3. Cook on low (4 to 5 hours on low, or 2.5 to 3 hours on high): Cover and cook until the potatoes are fork-tender. At the 3-hour mark on low, give them a quick stir to make sure the top layer isn’t drying out. If it looks dry, add a splash more broth.
  4. Add the creamy ingredients (5 minutes): When the potatoes are tender, scatter the cream cheese cubes and butter pieces over the top. Let them sit for about 2 minutes to soften from the residual heat.
  5. Mash or mix (5 to 7 minutes): Use your potato masher to break everything up, or if you want super-smooth potatoes, use a hand mixer on low speed. Be careful not to over-mix — stop as soon as there are no more lumps.
  6. Finish with milk and sour cream (3 minutes): Pour in the warmed milk or cream and add the sour cream. Stir gently with a rubber spatula until everything’s combined. Taste and adjust salt and pepper.
  7. Keep warm until serving: Switch your slow cooker to the ‘warm’ setting. The potatoes will stay perfect for up to 4 hours. Stir them every hour or so to keep the top from forming a skin. If they thicken too much, stir in a splash of warm milk.

Notes

Don’t skip rinsing the potatoes to prevent gluey texture. Warm your milk or cream before adding to avoid shocking the potatoes. Resist the urge to peek too often. If potatoes seem watery, leave the lid off for 10-15 minutes on warm setting.
