Caramelized Onion and Horseradish Smashed Potatoes

By: brightlightz  
"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."

Original Recipe Yield 8 servings
 

Ingredients

  • 3 tablespoons butter
  • 4 onion, sliced and separated into rings
  • 1 tablespoon white wine vinegar
  • 1/2 teaspoon ground dried thyme
  • 6 large baking potatoes, peeled and cubed
  • 1 tablespoon Dijon mustard
  • 2 tablespoons prepared horseradish, or to taste
  • salt and cracked black pepper to taste
  • 1/4 cup softened butter
  • 3/4 cup half-and-half

Directions

  1. Melt 3 tablespoons butter in a large skillet over medium-high heat. Add the onions and cook for 5 minutes. Reduce heat to medium, and continue cooking, stirring frequently, until the onions have softened, and achieved a deep brown color, 15 to 25 minutes. Stir in vinegar and thyme, and cook for 5 minutes more.
  2. While the onions are cooking, place cubed potatoes in large pot and cover with salted water. Bring to a boil, then reduce heat to medium-low, cover, and simmer until the potatoes can be pierced easily with a fork, about 20 minutes. Drain the potatoes in a colander, and allow to steam for a minute.
  3. To finish the dish, transfer the potatoes to a serving bowl, and use a potato masher to mix with Dijon mustard, horseradish, salt and cracked black pepper until smooth. Mix in softened butter, caramelized onions, and half-and-half until onions are distributed evenly.
