Even the pickiest eaters won't be able to resist this DIY spread complete with all the toppings!

We love a comfort dish with a twist, which is why we’re enjoying the latest entertaining craze: the mashed potato bar. This trend takes mashed potatoes from a basic side to a yummy party dish without breaking the bank. It’s as simple as serving the creamy spuds in a large bowl and placing various toppings in smaller bowls. Then, guests can scoop and customize a serving of mash to satisfy their salty, smoky or cheesy cravings. If this DIY spread sounds like the perfect fit for your next tailgate or birthday party, we’ve got a couple shortcuts to make preparing it a breeze. Here’s how to create a crowd-pleasing mashed potato bar and several topping ideas to get your taste buds watering!

What is a mashed potato bar?

A mashed potato bar calls for serving plain creamy spuds along with toppings like meat, vegetables, seasonings and cheese in separate bowls. Once guests help themselves to a portion of mash and toppings, the dish can be enjoyed out of individual-sized vessels like bowls, mason jars or even martini glasses for festive flair!

The key to making a big batch of mashed potatoes

Whipping up fluffy mashed potatoes for a crowd is easier than you think. The secret? Simply grab a slow cooker, fill with your peeled potatoes and ingredients and let it cook for hours. Then, quickly mash the potatoes and stir in creamy ingredients before serving.

This hassle-free method frees you up from boiling the spuds, making them tender and velvety rather than watery or mealy. You also don’t have to deal with hot water splashing everywhere as you’re draining the potatoes. Bonus: Switching your slow cooker’s setting to warm keeps the mashed potatoes heated until you’re ready to serve.

How to make the ultimate mashed potato bar

Below, Nilsson shares her Mashed Potato Bar recipe, which uses a plain mash made from basic potatoes. But, you can experiment with various types of potatoes and flavorings for a more vibrant mashed potato bar. “A fun way to mix it up would be to offer a few kinds of mashed potatoes as the ‘base’ for your bar — try mashed sweet potatoes, roasted garlic or ranch mashed potatoes,” she says. Give it a go and see your loved ones devour these spuds in no time!
