Make your next side dish memorable with these ultra-creamy Boursin Mashed Potatoes. This recipe uses Yukon Gold potatoes and Boursin Garlic & Fine Herbs cheese to create a velvety, flavorful side perfect for holidays or weeknight dinners.

Ingredients

Scale
  • 3 lbs Yukon Gold potatoes, peeled and quartered
  • 1 cup whole milk or heavy cream
  • 8 tablespoons unsalted butter, cut into pieces
  • 5.2 ounces Boursin Garlic & Fine Herbs cheese, softened
  • 1 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper, or to taste
  • 1/4 cup sour cream (optional, for extra richness)

Instructions

  1. Place the peeled and quartered potatoes in a large pot and cover them with cold, salted water.
  2. Bring the water to a boil over high heat, then reduce heat to maintain a steady simmer. Cook until the potatoes are fork-tender, about 15 to 20 minutes.
  3. Drain the potatoes completely in a colander. Return the hot, drained potatoes to the empty pot.
  4. Heat the milk or cream and butter in a small saucepan over medium heat until the butter is melted and the liquid is warm. Do not boil.
  5. Mash the potatoes thoroughly using a potato masher or a ricer until they are mostly smooth.
  6. Add the softened Boursin cheese, warm milk mixture, salt, and pepper to the potatoes.
  7. Using a hand mixer or a sturdy whisk, whip the potatoes until they are smooth and velvety. If using, mix in the sour cream now for added creaminess.
  8. Taste the potatoes and adjust salt and pepper as needed. Serve immediately as an elevated potato side dish.

Notes

  • For the smoothest texture, use a potato ricer instead of a standard masher.
  • You can prepare the potatoes (boil and mash) ahead of time. Store them covered in the refrigerator. Reheat gently on the stove with extra milk before adding the Boursin cheese.
  • For a steakhouse style potatoes flavor, add 1 teaspoon of roasted garlic base when adding the milk.
