Ingredients

Scale

Potatoes

  • 2 pounds Yukon gold potatoes, cut into 1-inch cubes
  • 1 tablespoon kosher salt (for cooking potatoes)

Flavors & Seasoning

  • 3 cloves of garlic
  • 2 sprigs fresh rosemary
  • ½ teaspoon kosher salt (for seasoning mashed potatoes)
  • ¼ teaspoon black pepper

Dairy

  • 4 tablespoons unsalted butter, softened
  • ½ cup heavy cream

Instructions

  1. Prepare the Potatoes: Peel (if desired) and cut the Yukon gold potatoes into 1-inch cubes to ensure even cooking. This size helps them soften quickly while retaining texture for smooth mashing.
  2. Cook the Potatoes: Place the cubed potatoes in a large pot and cover with cold water. Add 1 tablespoon of kosher salt to the water for seasoning. Bring to a boil over medium-high heat, then reduce to a simmer. Cook until the potatoes are very tender, about 15-20 minutes, when pierced easily with a fork.
  3. Roast Garlic and Rosemary: While the potatoes cook, peel the garlic cloves and slightly crush them. In a small pan over low heat, gently warm the garlic cloves and rosemary sprigs in the butter until fragrant, about 3-5 minutes, being careful not to burn the garlic. This infuses the butter with flavor.
  4. Drain the Potatoes: Once tender, drain the potatoes thoroughly and return them to the pot or a large mixing bowl to prepare for mashing.
  5. Mash the Potatoes: Using a potato masher or fork, mash the potatoes until mostly smooth, leaving slight texture if preferred. Slowly add the rosemary-garlic infused butter and heavy cream while continuing to mash until creamy and well combined.
  6. Season to Taste: Stir in ½ teaspoon kosher salt and ¼ teaspoon black pepper. Adjust seasoning as needed for your preference.
  7. Serve Warm: Transfer the mashed potatoes to a serving bowl and optionally garnish with additional fresh rosemary leaves. Serve immediately to enjoy the full flavor and creamy texture.

Notes

  • Yukon gold potatoes are preferred for their creamy texture and buttery flavor ideal for mashing.
  • You can swap heavy cream with half-and-half or whole milk for a lighter version.
  • Roasting garlic and rosemary in butter infuses a deeper flavor than adding raw ingredients.
  • Do not overcook potatoes to avoid waterlogging; they should be tender but not falling apart.
  • For dairy-free adaptation, use olive oil or vegan butter and coconut cream instead of butter and heavy cream.
