Real Life Duchess Style Potatoes

Real Life Duchess Style Potatoes

I am calling these Real Life Duchess Style Potatoes because the way they are traditionally made in a restaurant is piped out onto a baking sheet and then served. Since that is not the reality in most households, I am making them in a casserole dish, using the ingredients that would normally be added in the traditional Duchess potato recipe.

Cuisine English


  • 6 Medium Potatoes preferably Yukon Gold but if all you have is Russet by all means used them
  • ¼ Cup Cream Cheese
  • ¼ Cup Sour Cream
  • ¼ Cup Parmigiano Reggiano plus a bit more for sprinkling on top
  • 2 Egg Yolks
  • A Splash of Cream
  • 1 Garlic Clove minced fine
  • ½ Stick of Butter
  • 1 Tablespoon Chopped Chives a bit more for the top
  • Salt and Pepper to Taste
  • Paprika for the Top


  • Peel the potatoes and cut them into eighths
  • Drop them into cold water as you work
  • Cook for 30 minutes or until the potatoes are soft when poked with a fork
  • Preheat the oven to 350F
  • Drain the water and once the steam has evaporated, put the potatoes back in the pan
  • Add in the butter and all the ingredients adding the egg yolk last
  • Mash with a hand masher and fork taking out as much of the lumps as possible
  • Transfer the mixture to your casserole dish
  • Take your fork and touch the potatoes and lift up to form peaks these will brown the best in the oven
  • Top with the chives, salt, pepper, and cheese
  • Cook for 35 minutes until potatoes are browned ( If you are making a larger amount or if you are taking from the refrigerator to the oven make sure to add in extra time)


These are my new favorite way to have mashed potatoes, and why not? These really kick up everyday mashed potatoes.
This is what they typically look like in a restaurant. Maybe you have had them?  
Yukon Gold are the best potatoes for mashing, but if you're like me, the ones that I have on hand are always Russets. The trick with Russets is not to whip too hard or too long or they get all gluttony on you. I like this Duchess style mashed potato recipe for the following reasons:

The Advantage to These Potatoes

    • They taste so much better than simple mashed potatoes, there is something more appealing about how the flavors come together when baked.
    • The dairy products and egg add an extra creaminess to the entire experience
    • The crispy peaks on the top add an extra bit of texture when you take a bite.
    • They can be made in advance as much as a whole day ahead. On a holiday or a dinner party day that is really a time-saver.
    •  They travel well- Sitting in your casserole dish they do not spill, leak, or smash. If you have one of those zip-up thermal casserole cozies then they will even stay warm until you arrive at your destination.
    • This recipe is quite versatile, meaning you can add or omit flavors to please your family or guests
    • Expanding this recipe to meet the needs of a larger gathering is simple

These potatoes can be a side dish and are filling enough to be the main course. the beauty of this recipe is it uses up leftover ham. We froze that last chunk of that ham from Easter (since we had finally got tired of eating it). A month later we pulled it out of the freezer to give it new life. Everyone loved these cheesy gooey potatoes.
