Ingredients

Deselect All

2 1/2 pounds Yukon Gold potatoes (5 to 6 medium), peeled and chopped

Kosher salt

2 sticks salted butter, cut into pieces, at room temperature

2 leeks (white and light green parts), thinly sliced and rinsed

1 teaspoon chopped fresh thyme

1 teaspoon chopped fresh rosemary

Freshly ground pepper

1/2 to 3/4 cup milk, warmed

Directions

Put the potatoes in a large saucepan and cover with cold water by 1 inch. Season generously with salt and bring to a boil. Reduce the heat to medium low and simmer until the potatoes are very tender but not falling apart, about 15 minutes.
Meanwhile, melt 4 tablespoons butter in a large skillet over medium heat. Add the leeks, thyme and rosemary. Cook, stirring, until the leeks soften, 12 to 15 minutes; season with salt and pepper and set aside.
Drain the potatoes and return to the pot over low heat; cook until any excess water evaporates, about 2 minutes. Add the remaining 1 1/2 sticks butter, reserving 1 tablespoon for topping, and mash with a potato masher until smooth and the butter has melted. Gradually mash in 1/2 cup milk and 1/2 teaspoon salt until creamy, adding up to 1/4 cup more milk as needed. Season with salt and pepper and stir in the cooked leeks.
Transfer the potatoes to a bowl; top with the remaining butter before serving.

Cook’s Note

Make-Ahead Plan: Make the mashed potatoes up to 3 days ahead; let cool, then cover and refrigerate. To reheat, transfer to a baking dish, stir in some milk, cover with foil and warm in a 350 degrees F oven until hot, 20 to 25 minutes. Top with butter.
