Sour Cream and Onion Mashed Potatoes

Those who know my eating habits really well can talk about my strong dislike for sour cream. Just the thought of it topping any food I'm about to ingest makes me a bit queasy. The funny thing is, if it's mixed into a dip or a sauce, I'll more than likely eat it. I just can't deal with it being used as a condiment.

With that being said, for me to come up with a recipe that calls for an entire container of sour cream is practically unbelievable. I've been trying to revisit foods I once cast off in order to give them another try. (I survived the olive revisit, but I'm still not a fan.) Given my love for sour cream and onion potato chips, I figured a potato dish would be the best way for me to revisit sour cream. And, I was really surprised by how much I enjoyed these mashed potatoes! Especially paired with the meatloaf I made on Sunday. There's hope for me and sour cream yet.

These mashed potatoes are great as they are or when topped with gravy. However, they'd be just as delicious - or dare I say, even more delicious - with some roasted garlic or with some crumbled bacon mixed in and shredded cheddar cheese on top.

So, how do you like your mashed potatoes?

Sour Cream and Onion Mashed Potatoes
Printable Recipe


  • 4 large russet potatoes, peeled and chopped into medium-sized pieces
  • 4 tablespoons butter
  • 1 8-ounce container reduced-fat sour cream
  • 1/2 cup milk
  • 1 scallion, finely sliced
  • Salt and pepper, to taste
  1. Bring a large pot of water to a boil. Boil the potatoes until fork tender, about 10-15 minutes. Drain well.
  2. In the same pot, combine potatoes with butter, sour cream, milk, scallion, salt, and pepper. Mash until there are no longer any large lumps. (If you prefer creamier potatoes, you can use a hand-mixer rather than a hand-held potato masher.)
  3. Serve immediately or keep warm until ready to serve.

WOW - I am all over these like a rotund boy on a reese peanut butter cup.... they look amazing Michelle. I am so exicted.

Thanks for sharing this one.
Jo - Thanks! I love mashed potatoes, too. To think they were inspired by one of my favorite potato chip flavors. :-)
Zesty - Ha! That is probably one of the best compliments about my recipes/cooking I've ever received. Hope you enjoy the potatoes as much as I did!
In a classic "D'oh!" moment, I accidentally rejected a comment by Lynn when I really meant to publish it. Thanks to email notification, however, I can copy and paste Lynn's comment here:

"Hey Michelle, great recipe, I often make something very similar, adding sometimes a bit of ranch dressing to add a little zing :) I think the idea with the roasted garlic sound fantastic."

Lynn - Thanks for your comment! I hope you can forgive me! As for the Ranch dressing, that sounds like a delicious addition to this recipe. Thanks for the suggestion! :-)

This sounds really good.. I love sour cream! I'll bookmark this for later. We very rarely had mashed potatoes at our house growing up because my dad had a childhood trauma with them. I'm only partially kidding.
Matt - If you love sour cream, I'd recommend you putting a dollop of sour cream on top of your helping of mashed potatoes! ;-)

Your poor dad...
Matt Casey said…
I shall put a generous helping of sour cream on top :)

Don't worry too much about my dad... the veracity of The Mashed Potato Story are a subject of vigorous debate each year... I'm a skeptic myself.

Great mashed potato recipe! Definitely creamy and full of flavor!
Meg - Thanks! The sour cream really did add an incredible richness to the mashed potatoes that I didn't miss adding more milk. :-)
