Ingredients

Scale

Potatoes

  • 2 lbs Yukon Gold potatoes, peeled and cut into 2-inch chunks

Dairy & Cheese

  • 5.2 oz Garlic & Fine Herbs Boursin cheese (or any preferred Boursin flavor)
  • 4 tbsp unsalted butter, softened
  • 1/2 cup whole milk, warmed
  • 1/4 cup sour cream (optional, recommended)

Seasonings & Garnish

  • 1 1/2 tsp salt, plus more to taste
  • 1 tsp salt (for boiling water)
  • 1/2 tsp freshly ground black pepper
  • 2 tbsp chives or parsley, chopped (for garnish)

Instructions

  1. Prep the Potatoes: Peel and cut 2 lbs Yukon Gold potatoes into even 2-inch chunks to ensure they cook uniformly.
  2. Boil: Place the potatoes in a large pot and cover with cold water. Add 1 tsp salt to the water. Bring to a boil over high heat, then reduce to a simmer. Cook for 15 to 20 minutes until the potatoes are fork-tender but not falling apart.
  3. Drain and Steam Dry: Drain the cooked potatoes in a colander and let them steam dry for 2 to 3 minutes to prevent watery mash and enhance fluffiness.
  4. Mash: Return the potatoes to the pot or a mixing bowl. Use a potato masher or ricer to mash until smooth, leaving a few lumps if a rustic texture is desired.
  5. Add Butter: Stir in 4 tablespoons of softened unsalted butter until melted and fully combined with the potatoes.
  6. Incorporate Cheese and Milk: Add 5.2 ounces of Boursin cheese and 1/2 cup of warm whole milk. Mix gently to combine without overworking the potatoes to avoid gumminess.
  7. Add Sour Cream and Season: Fold in 1/4 cup sour cream if using, then season with 1/2 teaspoon freshly ground black pepper and additional salt to taste. Mix just until incorporated.
  8. Taste and Adjust: Taste the potatoes and add more milk for a smoother texture or extra Boursin for a stronger flavor if desired.
  9. Garnish and Serve: Transfer the mashed potatoes to a serving bowl. Garnish with chopped chives or parsley and an optional pat of butter if you want to add extra richness and visual appeal.

Notes

  • Use Yukon Gold potatoes for the best creamy texture; Russets can be used in a pinch.
  • Warm your milk and soften butter before adding to prevent gums and maintain smoothness.
  • Avoid over-mixing to ensure fluffy and light mashed potatoes without a gummy texture.
  • This recipe is naturally gluten-free; just verify your Boursin cheese is gluten-free as well.
  • Dairy-free alternatives can be made using plant-based butter, unsweetened oat milk, and dairy-free Boursin.
  • Leftovers keep well in the fridge for up to 4 days; reheat gently with a splash of milk to maintain creaminess.
  • You can freeze mashed potatoes, but thaw overnight and heat slowly to preserve texture.
  • For a rustic mash, leave extra lumps; for super smooth, use a potato ricer.
