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)

Directions

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

Drain the cooked potatoes and return them to the pot. Mash them with a potato masher or use a ricer for a smoother texture.

Step 6

In a small saucepan, gently heat the heavy cream until warm. Add 4 tablespoons of butter and stir until melted.

Step 7

Pour the warm cream mixture into the mashed potatoes, stirring to incorporate. Add the caramelized onions and horseradish, mixing well.

Step 8

Season the mashed potatoes with 0.5 teaspoons of salt and black pepper. Taste and adjust seasoning as needed.

Step 9

Transfer the mashed potatoes to a serving dish. Garnish with chopped chives, if desired, and serve warm.
