So join us as we explore how easy it can be to whip up some homemade mashed potatoes with minimal effort required!
You Will Need
- Broth: You can use store-bought broth or homemade. I like to use homemade broth because it typically has a lot more flavor.
- Potatoes: I recommend using russet potatoes for this recipe, as they create the best texture. Peel and slice them into ¼-inch thick pieces. If you prefer, yukon gold potatoes may also be used.
- Salt and Pepper: Make sure you don't skip the seasonings - potatoes really need them.
- Butter: Melted butter will help give the potatoes their creamy texture. Diced butter is used for finishing the mashed potatoes.
- Cream Cheese: Adding cream cheese to your mashed potatoes will give them an extra creaminess and flavor.
- Sour Cream: This is an optional addition, but it adds a delicious tangy flavor and helps lighten the potatoes a bit.
Step by Step
For the full recipe with measurements, see the recipe card at the end of the post.
First, start by bringing the broth to a boil either in the microwave or on the stove.
Next, place the peeled and sliced potatoes into your slow cooker and pour the liquid on top of them. Season with salt and pepper, then brush the potatoes with melted butter.
Cover the potatoes with parchment paper, pressing it down as needed. Place the lid on your slow cooker and cook on either high for 3-4 hours, or low for 5-6 hours.
The cooking time will vary based on how warm your slow cooker is.
Once the potatoes are cooked through and tender, discard the parchment paper and add in the remaining ¼ cup of butter to the slow cooker. Use a potato masher to mash the potatoes until they reach your desired consistency.
For more creamy potatoes, you could also use a potato ricer. (Some people prefer to use a hand mixer. I find this can make this Slow cooker mashed potatoes recipe a little gummy, but this is another option if you prefer.)
Add in the cream cheese and stir until combined. I like to place the lid back on for a minute or two to let the cream cheese soften.
Then, stir in the sour cream to lighten up the potatoes and season with additional salt and pepper as needed.
Serve the mashed potatoes warm, and enjoy!
Tips & Tricks
- You can cut the potatoes in chunks if you like, but according to America’s Test Kitchen, sliced potatoes cook more evenly. (I have done it both ways and both work!)
- Try to make sure all the potatoes are submerged in liquid to prevent discoloring while they cook.
- Feel free to add in other flavorings and toppings. Roasted garlic is lovely added to the potatoes when mashings. Cheddar, parmesan cheese, bacon, and chives all make great toppings.
Serving Suggestions
Serve these creamy mashed potatoes with a picanha roast, oven roasted tri tip, Instant Pot french onion chicken, Ninja Foodi turkey, or Blackstone steak.
Round out the meal with Brussels sprouts kale salad, air fryer asparagus, baked parmesan asparagus, or Instant Pot green beans.
