How To Make Slow Cooker Mashed Potatoes
Step One: Peel and Dice
For this recipe, I used russet potatoes because they are the best for mashing.
If you want to make rustic mashed potatoes, use red potatoes and leave the skins on.
When dicing the potatoes, try to make them somewhat uniform in thickness so that they will all be done cooking at about the same time.
Step Two: Chicken Broth
After adding the diced potatoes to the slow cooker, you’ll need to add some liquid.
I like to use chicken stock because it adds flavor but water can be used instead if you prefer.
Step Three: Butter
Cut the butter into cubes and add it to the diced potatoes.
Step Four: Cook
Cover and cook on high for 4-5 hours, until tender.
Some of the potatoes, especially around the edges, may brown a bit in spots but it fine!
Step Five: Mash
Use a potato mashed to mash the potatoes.
Step Six: Add Liquid
Add half of the whole milk to start with and add more later if needed.
You can also add one cup of sour cream but my family prefers mashed potatoes without the sour cream so I didn’t add it.
Step Seven: Beat
Use a hand mixer (or fork) to beat in the milk until smooth but don’t over overmix.
Slow Cooker Mashed Potatoes FAQs
1. Why make mashed potatoes in a slow cooker when they aren’t that hard to make on the stove? Making mashed potatoes in a crock pot is more hands-off and leaves another burner on the stove open for other dishes.
2. Can the potato skins be left on? Yes, you leave the skins on, usually made with red potatoes, and make rustic mashed potatoes instead.
3. What about mix-ins or toppings? Yes to all of them! You can make garlic mashed potatoes, loaded potatoes or cheesy potatoes. Any seasoning or spices can be added right away so the flavor gets cooked in. Other ingredients like cheese or bacon can be added at the end.
4. Are these slow cooker mashed potatoes really smooth? Mine were not perfectly smooth. For the smoothest mashed potatoes, try using a potato ricer.
