"I recreated this recipe from some mashed potatoes I had at an Irish restaurant, but they also go great with German dishes. You can alter the amount of mustard to your taste."

  1. Place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 20 minutes. Drain and allow to steam dry for a minute or two. Mash potatoes in a large bowl with the butter and milk, and season with salt and pepper.
  2. Whip the potatoes using an electric mixer set on medium until smooth, 3 to 4 minutes, adding more milk if the potatoes are too dry. Beat in the whole grain mustard, and serve immediately.

The first time I had mustard mashed potatoes was at an Irish restaurant served with bangers 'n mash. The flavor is somewhat similar to a German style potato salad. It isn't something I could eat with just any meal, but when paired with the right meats and sauces, they are absolutely delish. (i.e., bangers 'n mash, corned beef 'n cabbage, old fashioned pot roast)

This is absolutely delicious with corned beef.

delicious just as written; the only change I made was using white potatoes rather than red and i don't think that really affected anything. Thanks for the recipe!

Very good. I was not quite sure about this and thought it would be a fail, but took a chance. I am glad I did. This was really very good. This reminded me of mustard potato salad. I used brown spicy mustard. I would fix this again. DH covered his with gravy and didn't comment.

Was it going to be traditional (boring) mashed potatoes for supper tonight or was it going to be mashed potatoes with, gasp, MUSTARD in them? In the end, the mashed potatoes with mustard prevailed. And I'm glad. So glad. Don't hesitate to make these. They're awesome good. Country-Style Steak, also from this site, these Mustard Mashed Potatoes, and green beans. What a meal.

Nice complement to our corned beef dinner. Added a little extra butter.

We made this with regular white potatos and it was very tasty.

These were pretty good but the mustard was too overpowering for us. Next time I will cut the mustard in half and try adding in parmesan cheese.
