Feed a crowd with the ultimate mashed potato bar at your next party, wedding, or celebration. How to create a crowd pleasing buffet with ideas for all sorts of delicious mashed potato toppings. It'll be the talk of the party!

There are so many things you can do with a mashed potato bar; the choices for mashed potato bar toppings are endless. Pretty much anything you think up you can use.

It's the perfect appetizer idea, or side dish, for a wedding or party. I experienced my first mashed potato bar, or rather a mashtini bar, at a blogging conference; I'd never seen such a beautiful thing in all my life.

It was filled with all sorts of delicious mashed potato toppings, along with all sorts of potatoes, including purple mashed potatoes! The mashed potatoes themselves were served in martini glasses, and you could go right down the buffet line, adding any mashed potatoes toppings you wanted.

You talk about delicious and one of my favorite things ever. That was hands down the BEST food I've ever had at a conference. Comfort food at its best, and man, was it delicious.

Why Create a Mashed Potato Bar?

When I created my first baked potato bar, I thought it only appropriate to also create a mashed potato bar. Because who doesn't love a loaded down cup of hot mashed potatoes smothered in cheese and bacon?

  • A mashed potato bar wedding buffet will definitely be a great idea and a favorite with guests.
  • A mash potato bar is also perfect for that big holiday family gathering, like Thanksgiving dinner, Christmas dinner, or Easter dinner.
  • New Year's is also a great time to put together a mashed potato martini bar. To save on cost, make a big batch of mashed potatoes, and have each guest bring their favorite toppings to add to the ones you provide. Then you get different perspectives, different ideas, and guests get to contribute their favorite topping idea to the mix.

How to Make Mashed Potatoes

I've got you covered with this delicious and easy mashed potatoes recipe.

Ingredient Notes:

  • Potatoes – I prefer to use yellow potatoes, but again, you can have fun with this and use all sorts of potatoes, including yellow, russet, red potatoes, even purple potatoes.
  • Salted Butter – Don't skimp on the butter; it gives the best flavor.
  • Heavy Cream or Whole Milk – While you can use skim milk, you'll get the best texture and flavor with whole milk or cream.
  • Sea Salt and Black Pepper – for added flavor.

Steps for Making Stovetop Mashed Potatoes:

  1. Wash, peel, and chop the potatoes.
  2. Boil the potatoes in a large saucepan on the stove over low to medium heat, until they're soft enough to easily jab with a fork, about 20-30 minutes.
  3. Drain the water off the boiled potatoes, and leave them in the saucepan.
  4. Add the butter and heavy whipping cream to the potatoes.
  5. Use a hand mixer to whip the potatoes, adding salt and pepper to taste. You can also use a potato masher if you don't have a hand mixer; your potatoes may just be a little bit chunky.
  6. Once they're whipped, they're ready to serve.

If you'd rather, you can make Instant Pot mashed potatoes instead.

How to Set up or Assemble a Mashed Potato Bar

Gather your ingredients for your potato bar… You’ll need mashed potatoes and toppings. Your main work will be cooking the potatoes and prepping any toppings for your guests to choose from.

Whether you’re getting together with friends for game night, hosting a family dinner, or setting up a potluck, a mashed potatoes bar is the perfect way to feed and entertain your guests. And it really doesn’t take a whole lot of time and effort on your part.

Mash Potato Bar Ideas and Expert Tips

  • If you'd rather use sweet potatoes over regular potatoes, you can make Instant Pot sweet potatoes.
  • Prep the toppings, adding each topping to a separate dish or compartment for serving. Prepping may involve cooking, re-heating, or simply chopping.
  • Set everything out buffet style, so your guests can create their very own delicious mashed potato creations.
  • If you're hosting a smaller gathering, try using a large charcuterie board with small bowls for a variety of toppings all around a large bowl of mashed potatoes.
  • If you're wondering how to keep the mashed potatoes warm without warmers, you can create a CrockPot mashed potato bar or Instant Pot mashed potato bar.

The Ultimate List of Mashed Potato Bar Toppings:

When it comes to what toppings are good on mashed potatoes, including what to put on mashed potatoes besides gravy, this list of toppings will answer that question in a most delicious way.

Recipe FAQ's

How much does a mashed potato bar cost?

Really, this depends. For a small family gathering, if you make your own mashed potatoes and put together just a few simple toppings, you can get away with less than $20. If you're creating a larger buffet for a large crowd, your cost will depend on how many ingredients and supplies are needed to feed said crowd.

What potatoes are best for a mash potato bar?

While I do prefer yellow potatoes or Yukon Gold potatoes, you can use any kind of potatoes you prefer, including Russet potatoes, red potatoes, even purple potatoes if you can find them. I've also gone so far as to search for the best mashed potatoes near me, and I found Bob Evans mashed potatoes in my grocery store. If you really don't want to make mashed potatoes, ready made potatoes could be just the thing.

Can you make mashed potatoes and toppings ahead of time?

Yes, you can. You can make mashed potatoes and prep most of the toppings 1-2 days ahead of time. You'll just need to store everything in airtight containers in the fridge.

How can you keep the mashed potatoes warm at a party?

You can either use a buffet server and food warmer. Or you can keep the mashed potatoes in a Crock Pot or Instant Pot on the “Keep Warm” setting.

How should you store leftovers?

Definitely store leftovers in airtight containers in the refrigerator.

  1. Having a mashed potato bar served in Christmas martini glasses, plus my sweet potato recipe- what else would you suggest for meat, veggies and salad?

    Reply
    • We’re having beef & asparagus. Another veggie, TBD. I’m doing the same but I don’t have martini glasses. I’ll check out the dollar store or borrow some.

    • In the search bar, search for “salads.” In the many posts that show up, one of my favorite Christmas salads is the “Layered Salad with Whatever Layers You Want.” It’s hard to beat! We always make a ham for Christmas.

  2. I’m planning to do this for my son’s graduation open house. If you were to reduce the toppings to the “must haves,” which toppings are most popular or essential? I want to make sure it is manageable to maintain for 3 hours.

    Reply
    • Amy, some of my favorites are the bacon, cheddar cheese, cheese sauce, sour cream, ham, sloppy joe meat, and green onion. Those would be my top picks, but it depends on what you prefer.

  3. 👋Hello! I love having mashed potato bars! I’m giving my daughter a baby shower next week and getting ready! I have a question…Menu is Mashed potato bar, hot chili served in cups, veggie tray. I’m thinking of having a side of meatballs, drumsticks or chicken tenders. What do you think, I just can’t decide!!! Thanks!!!

    Reply
    • Hey Mary, this sounds like a great idea! Hmmm, with a mashed potato bar, I’d be tempted to go with chicken tenders. Chicken just pairs so well with potatoes, and it sounds delicious!
