How many potatoes per person for mashed potatoes?

You’ll want about 1/2 pound of unpeeled potatoes per person. This may be a little on the high side, but who ever complained about having a few leftover mashed potatoes? It’s always best to have plenty than to run out!

Can I make the make the mashed potatoes ahead of time?

Yes! You can make them ahead and keep them on warm until time to eat or even make them up to 3 days in advance and reheat in the slow cooker.

What are the best ingredients to add to mash with potatoes?

I’ve had mashed potatoes using milk, broth, cream cheese, just about anything you can think of!

But, for the best traditional, homestyle, fully amazing mashed potatoes you have to go for heavy cream, butter and salt. That’s all you really need for the best full flavored, fully comforting mashed potatoes of all time!
