Ingredients
2 lbs Yukon Gold or Russet potatoes
2 tablespoons olive oil
2 large yellow onions, thinly sliced
4 tablespoons butter
1/2 cup heavy cream (warmed)
1 1/2 teaspoons salt (divided)
1/2 teaspoon black pepper
2 tablespoons chopped fresh chives (optional)
Instructions
1. Peel and chop potatoes into even chunks. Place in a pot, cover with cold water, and add 1 teaspoon of salt.
2. Bring to a boil, then simmer until fork-tender, about 15–20 minutes.
3. While potatoes cook, heat olive oil in a pan over medium-low heat. Add onions and a pinch of salt.
4. Cook onions for 25–30 minutes, stirring occasionally, until caramelized and golden brown.
5. Drain the potatoes and return to the hot pot to remove excess moisture.
6. Mash the potatoes until smooth using a masher or ricer.
7. Stir in the butter and warmed heavy cream until creamy.
8. Season with remaining salt and pepper.
9. Fold in most of the caramelized onions, reserving some for topping.
10. Transfer to a serving bowl, top with reserved onions and chives. Serve warm.
Notes
For best flavor, caramelize the onions slowly on low heat—don’t rush this step.
Warm the cream before adding it to prevent the potatoes from seizing.
You can make this dish up to 2 days in advance and reheat with a splash of milk.
