Horseradish and Dijon mustard flavor these potatoes. Pair them with steak or tuna.

How to Make It

Step 1

Melt 1 tablespoon butter in a medium nonstick skillet over medium-high heat. Add onion and sugar; sauté 10 minutes or until caramelized. Remove from heat; stir in vinegar, if desired.

Step 2

Place potato in a saucepan, and cover with water. Bring to a boil. Reduce heat; simmer 15 minutes or until tender.

Step 3

Drain and return potato to pan. Add 3 tablespoons butter and milk; mash to desired consistency. Cook 2 minutes or until thoroughly heated, stirring constantly.

Step 4

Combine Dijon mustard and remaining ingredients in a small bowl, stirring with a whisk until blended. Add Dijon mustard mixture and caramelized onion mixture to potato mixture, stirring to combine.

I enjoyed this twist on mashed potatoes - contrary to other raters, I did not find the amounts of mustard or horseradish to be too much. Paired great with tuna, I think because the mashed potatoes were slightly reminiscent of tartar sauce. Didn't love the color though, as the mustard made the potatoes a dullish brown, and would use less onion..

I have been making horseradish mustard for years that come out great. I just add about 1 tablespoon of a horseradish mustard for ever 2 lbs of potatoes (I usually make my them in 2lb batches). Some of the reviews mentioned using with gravy but I would suggested eating these potatoes on their own.

I served this and another mashed potato recipe at Thanksgiving. I agree that the mustard taste was too strong. I felt like the tartness competed with the gravy. I would try again with less mustard next time. I caramelized extra onions and froze the extra in anticipation of making again.

These were very tasty! I cut the recipe in half and reduced the mustard to 1 tablespoon (for half the recipe.) My husband absolutely loved these. They had great flavor from the horseradish and mustard. I think they would go great with roast beef. Next time, I may add some cooked bacon to the final potatoes.

Did not like at all. A lot of work, I made a large batch for Christmas. I think the mustard ruined it and I didn't use as much as it called for. I've made caramelized twice baked potatoes in the past, one of my favorites, and thought I would love these. I will not make them again. I never thought I would not like a potato dish, but I was wrong. yuk...Don't waste your time. (by the way, it takes a lot longer to caramel the onions then the recipe says)

Followed the suggestions about the mustard, thanks. Turned out great, provided an unexpected variation on mashed potatoes. Served with CL double-cheese meatloaf but would probably be much better with grilled steak.
