FAQs & Tips

What type of potatoes should you use?

 I recommend russet potatoes. Normally waxy potatoes, like red potatoes, work well with slow cooking because they hold their shape better during the long cooking process. However, this is not the case here. Because waxy potatoes they are low in starch, they do not break down as well as other options. This makes them more likely to result in gummy mashed potatoes.

Do you need to pre-cook the potatoes?

Nope. The only prep work involved is peeling & chopping. Technically, you don’t even have to chop the potatoes, you an add them whole if you want. They will just take longer to cook. 

Can you leave the skin on the potatoes?

Of course. If you like to leave the skin on your mashed potatoes, then go ahead and do so. 

Can you mash the potatoes directly in the slow cooker?

You can! Another bonus to this recipe is that you mash the potatoes directly in the slow cooker, no need to dirty up another pot. I use a hand blender but the potatoes will be so tender that a hand potato masher will also do the trick. It all depends on how smooth you like your potatoes. 

What should you add to your mashed potatoes?

What do you add to your mashed potatoes? I add salt, pepper, garlic powder, milk, and butter. I have seen people add sour cream, half and half, cheese, etc.  Use what I have written in the recipe box as a guide and use the mashed potato ingredients that you prefer. 

Can you make this vegan?

While these mashed potatoes are vegetarian, they are not vegan because of the butter and milk (depending on what you use). To make this vegan, simply use a vegan butter, vegetable broth, and a milk alternative like almond milk. 

Can you make this Whole30 compatible?

Easily! Make this Whole30 compatible by using ghee in place of butter and a nut milk like almond milk.

Can you prep this ahead of time?

Yes! Peel and chop the potatoes, put them in a large bowl, completely cover the potatoes with cold water and store them in the refrigerator until they’re ready to be drained & added to the slow cooker. You can do this up to 24 hours in advance. 

What happens if you over-work the potatoes?

They will turn gummy. When potatoes are mashed, starch is released. The more you handle the potatoes, the more starch gets released and when too much starch gets released, the potatoes become gummy.

How do you store leftovers?

Store leftover crockpot mashed potatoes in the refrigerator for up to 4 days. 

What size slow cooker did you use?

I used a 3.5 quart slow cooker . If you plan on making this for a large crowd, I suggest doubling the recipe and using a larger slow cooker.

  2. Interesting. Do the white sweet potatoes taste the same as orange ones? I love sweet potatoes, I’ve just never had this kind. The recipe sounds delicious, though!

  3. These mashed sweet potatoes look delicious! I had no idea there were white sweet potatoes – we grow the orange ones in our garden and enjoy them year round. I’m going to have to try this recipe.
