Recipe Information
Ingredients
- 2 pounds Russet potatoes
- 6 tablespoons Unsalted butter
- 2 medium Yellow onions
- 1 tablespoon Olive oil
- 1 cup Heavy cream
- 2 tablespoons Prepared horseradish
- 1.5 teaspoons Salt
- 0.5 teaspoons Black pepper
- 2 tablespoons Fresh chives, chopped (optional garnish)
Instructions
Peel and cube the potatoes into 1-inch pieces. Place them in a large pot and cover with cold water, adding 1 teaspoon of salt to the water.
Bring the pot of potatoes to a boil over medium-high heat. Reduce the heat to a simmer and cook for 15-20 minutes, or until the potatoes are fork-tender.
While the potatoes cook, peel and thinly slice the onions. Heat 2 tablespoons of butter and the olive oil in a large skillet over medium heat.
Add the onions to the skillet, stirring occasionally. Cook for 20-25 minutes until golden brown and caramelized. Lower the heat if they begin to brown too quickly to prevent burning.
Drain the cooked potatoes and return them to the pot. Mash them with a potato masher or use a ricer for a smoother texture.
In a small saucepan, gently heat the heavy cream until warm. Add 4 tablespoons of butter and stir until melted.
Pour the warm cream mixture into the mashed potatoes, stirring to incorporate. Add the caramelized onions and horseradish, mixing well.
Season the mashed potatoes with 0.5 teaspoons of salt and black pepper. Taste and adjust seasoning as needed.
Transfer the mashed potatoes to a serving dish. Garnish with chopped chives, if desired, and serve warm.
