Sour Cream and Onion Mashed Potatoes

  • By KJ

Creamy, dreamy, with a hint of green, these Sour Cream & Onion Mashed Potatoes take your classic mashed potatoes to the next level.

Velvety gold potatoes are boiled until fork tender and whipped with butter, tangy sour cream, heavy cream, and green onions to create a cloud-like side dish.

I love that this is sort of a traditional Thanksgiving dish…and also sort of like an elevated potato chip.

And speaking of chips, these mashed potatoes double as an amazing dip. Serve with potato chips for a crunchy contrast.

This is a simple side dish that takes next to no time to whip up — so you can spend more time with the people you love this Thanksgiving!

Sour Cream and Onion Mashed Potatoes

Sour Cream & Onion Mashed Potatoes

All the classic flavors of sour cream and onion in mashed potato form…count me in! These mashed potatoes are creamy and dreamy and make for a perfect side dish for any occasion. 

Mashed Potato Ingredients

Yukon Gold potatoes

These potatoes give you a creamier result. If you need a substitute, you can try russet potatoes, although the texture will be a bit fluffier and less creamy. Peel the potatoes and cut them into 2-inch pieces. 

Butter

I used salted butter for this recipe.

Sour cream

Full-fat sour cream tastes the best. It’s the holidays — time to indulge a little! 

Heavy cream

Green onion (chopped)

You could swap these out and use chives instead. 

Salt & pepper

Chopped potatoes in a pot.

How To Make Sour Cream & Onion Mashed Potatoes

1

Boil the potatoes.

Add the potatoes to a large pot and fill with just enough water to cover the tops of the potatoes. 

Bring to a boil over high heat, and boil until the potatoes are fork tender (but not crumbly). 

Drain and transfer the potatoes back into the pot or a large bowl. 

2

Mix in the other ingredients.

Add in the butter, sour cream, and heavy cream. 

Use either a potato masher or an electric mixer to mix the mashed potatoes until smooth or until the potatoes reach the consistency you like.

Fold in the green onion, salt, and pepper.

3

Serve! 

Transfer the sour cream and green onion mashed potatoes to a serving dish. Garnish with extra pads of butter and additional chopped green onion. 

Enjoy!

4

Wash the dishes. How sad.
