Ingredients

5 pounds russet potatoes (scrubbed, peeled, and chopped into 2 inch chunks)
3 cups low sodium chicken broth
1 teaspoon Kosher salt (plus more to taste)
1/2 cup whole milk (warmed)
1/2 cup salted butter (at room temperature, plus more for serving)
1 1/2 cups sour cream (at room temperature, see note)
handful chives (snipped, for serving)

Instructions

Place the potatoes, chicken broth, and salt in a large slow cooker. Cover and cook on high for 4-4.5 hours, or until the potatoes are fork tender. Carefully drain off any excess broth, then return the potatoes to the crock pot.
Keep the crock pot on the warm setting. Give the potatoes a quick mash with a potato masher, then drizzle in the milk, continuing to mash. Add the butter and sour cream, stirring it into the potatoes, and allowing them to soak up all the liquid, mashing a bit more, if needed.
Taste and season with additional salt, if necessary. Stir in chives, then top with a few extra pats of butter. Cover the slow cooker, allowing the butter to melt on top before serving. The potatoes can be kept on the warm setting for up to 2 hours.

Notes

If you want your mashed potatoes to be creamier, you can beat them with a hand mixer. Just be careful to not over beat, as potatoes can become gluey.
These have a pronounced sour cream flavor (which we love!). If you prefer, start by using 1 cup sour cream, then add the rest if desired.
We find these are PLENTY rich, but if you really want to go all out, feel free to substitute the milk with half and half or cream.
Leftover potatoes keep well stored in an airtight container in the fridge for up to 5 days.
Reheat potatoes in the microwave, oven, or crock pot, adding an extra splash of milk and a bit more butter to keep them creamy.
