"Caramelized onions give this incredible side dish a subtle sweetness, and the addition of horseradish gives it a little attitude! They make an absolutely fabulous side dish to prime rib, and have become a tradition every year at family holiday gatherings! To save time, the caramelized onions can be made ahead of time and refrigerated, then warmed before adding to the potatoes." — brightlightz

We loved these potatoes! Beautiful rich color from the caramelized onions and deeply flavored. Definitely worth the extra effort and time it took to caramelize the onions. Just enough horseradish and Dijon to make these interestingly different, although I wouldn't hesitate to add more horseradish. I found I didn't need the extra butter at the end - the butter used to caramelize the onions was enough. It was nice to find a different and delicious spin on mashed potatoes.
Not very good at all!!! Will not make again
This side dish was great - my family (kids, too!) liked it...a nice flavor with a little tang, but not too much for those who don't like spice. It didn't take too long to make and didn't have any unusual ingredients, that is nice when you have a family and house to keep up while preparing meals. It made a huge heap and we served it with pork tenderloin and steamed broccoli - it was perfect. I'd recommend it - a nice twist on mashed potatoes...
Fantastic recipe! I added a couple of cloves of fresh roasted garlic, but add garlic to almost everything. I also added in a couple of dashes of white pepper!
This recipe is fantastic! The only change I made was to substitute the white wine vinegar to half white cooking wine, half cider vinegar, because I didn't have white wine vinegar on hand. For the small amt. required, I doubt it would have made much difference. But the flavor! I had 3 helpings, my boyfriend loved it as well. I know I'll be making this again & again. Thanks for the recipe! ADD-ON So, I made this again, and it was even better this time. I boiled the potatoes with minced garlic, used skim milk instead of half & half, and this time I sauteed chopped cabbage (about 2-3 cups) in bacon grease 'til tender, and added along with the onions. It was very simaler to Irish colcannon and tasted great with the corned beef I prepared. Everyone who loves horseradish and potatoes should try this dish!
I thought this was really delicious. When I went to make it I found I had only 1 rather elderly potato. So I made instant mashed and added the seasonings. It was great and my guest had no idea I hadn't made it from scratch!
Yummy side dish! I did have to add more 1/2 & 1/2 to make it creamy enough and also a bunch more horseradish, because we like spicy! :)
very yummy. i scaled back to 6 servings, and even opted to use 2 sweet vidalia onions over the 3 they suggested. it was plenty!!! also diced for ease of mixing and eating. omitted thyme since i didnt have it. served with flat iron steak w/ blue cheese chive butter (also from site) the first night, and leftovers with a pork tenderlion and mushrooms w/ soy sauce glaze (again from this site lol) everybody raved about these!!
