Recipe Information
Ingredients
- 2 lb Russet potatoes
- 6 tbsp Unsalted butter
- 2 large Yellow onion
- 2 tbsp Olive oil
- 1 cup Heavy cream
- 2 tbsp Prepared horseradish
- 2 tsp Salt
- 0.5 tsp Ground black pepper
- 2 tbsp Fresh parsley (optional, for garnish)
Instructions
Peel and chop the potatoes into evenly sized chunks, about 1-2 inches each, to ensure even cooking.
Add the chopped potatoes to a large pot and cover with cold water. Add 1 teaspoon of salt to the water. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15-20 minutes, or until the potatoes are fork-tender.
While the potatoes are cooking, prepare the caramelized onions. Peel and thinly slice the yellow onions.
In a large skillet over medium heat, add olive oil and 2 tablespoons of butter. Once the butter has melted, add the sliced onions with a pinch of salt. Cook, stirring occasionally, until the onions are golden brown and caramelized, about 20-25 minutes. Reduce heat if the onions are browning too quickly.
Once the onions are caramelized, set them aside. Reserve a small portion for garnish, if desired.
Drain the cooked potatoes and return them to the pot. Add the remaining 4 tablespoons of butter and mash the potatoes until smooth and creamy.
Gradually mix in the heavy cream, stirring until fully incorporated and the potatoes reach your desired consistency. Adjust the amount of cream as needed.
Stir in the prepared horseradish, 1 teaspoon of salt, ground black pepper, and the caramelized onions (reserving some for garnish, if desired). Mix until well combined.
Taste the mashed potatoes and adjust seasoning with additional salt and pepper if needed.
Transfer the mashed potatoes to a serving dish. Garnish with the reserved caramelized onions and fresh parsley if using. Serve warm and enjoy!
