When it comes to mashed potatoes, there are more than just your standard variety - from brown butter mashed potatoes to cream cheese mashed potatoes. You can even mix it up with sweet potatoes with these slow cooker mashed sweet potatoes.
For anyone that has watched Chopped, you probably know how many chefs made a mistake by adding too much truffle oil at the end.
Truffles are actually a fungus and many times infused with oil. If you've never had truffle oil, it is a difficult flavor to describe. It is woody, garlicky, earthy and fruity all in one. Is is made for potatoes however. I mean who doesn't love truffle oil French fries.
It is one of those ingredients that can definitely overpower the dish. But after testing this truffle mashed potatoes recipe multiple times, I think I found the perfect balance, where you get that hint of truffle with every bite.
So if you're looking for a unique side dish, this is the perfect option.

Ingredient Notes
- Russet potatoes - the best potatoes for creamy mashed potatoes as it has enough starch to work well.
- Sour cream - adds a little sourness to the dish that complements the butter and truffle oil.
- Unsalted butter - you can't have mashed potatoes without some butter. Adds to the richness factor.
- Truffle oil - use white or black truffle oil. Just keep in mind each tastes slightly different.
Ingredient Swaps
As with any recipe, you can mix up some of the ingredients. Some variations include:
- While I always use Russet potatoes for a mashed potato recipe, Yukon Golds can be used as well.
- I like sour cream for the added sourness, but Greek yogurt is a good substitute.
- I'm partial to truffle oil as it is easier to find and has many uses, but you can replace with truffle butter.
