Ingredients

Scale

Potatoes

  • 2 1/2 lbs Yukon gold potatoes, peeled and diced into 1 1/2-inch portions
  • Salt and freshly ground black pepper, to taste

Butter & Garlic

  • 6 Tbsp butter, divided
  • 4 cloves garlic, finely minced

Dairy & Cheese

  • 3 – 4 Tbsp half and half
  • 1/2 cup (slightly packed) finely shredded parmesan cheese

Eggs

  • 4 large egg yolks

Garnishes (optional)

  • Minced fresh parsley
  • Finely grated parmesan cheese

Instructions

  1. Preheat Oven: Preheat your oven to 425 degrees Fahrenheit and line a baking sheet with parchment paper to prepare for baking the duchess potatoes.
  2. Boil Potatoes: Place the diced Yukon gold potatoes in a large pot, cover with cold water by 1 to 2 inches and season with 1 tablespoon of salt. Bring to a boil over medium-high heat, then reduce to medium-low, cover with a lid, and simmer for 15 to 20 minutes until the potatoes are very tender and nearly falling apart when pierced. Drain thoroughly.
  3. Sauté Garlic in Butter: While potatoes cook, dice 4 tablespoons of butter into small pieces and melt them in a small saucepan over medium heat. Add the minced garlic and sauté until lightly golden and softened, about 1 to 2 minutes. Be careful not to burn the garlic.
  4. Mix in Half and Half: Remove the garlic butter from heat, stir in 3 tablespoons of half and half, then transfer the mixture to a small bowl to avoid further cooking of the garlic. Set aside.
  5. Mash Potatoes: Return the drained potatoes to a large mixing bowl and mash them well with a potato masher or press through a potato ricer until smooth with no lumps remaining.
  6. Combine Cheese and Butter Mixture: Stir the finely shredded parmesan cheese and the warm garlic butter mixture into the mashed potatoes. Season with salt and freshly ground black pepper to taste, mixing with a wooden spoon until fully combined.
  7. Add Egg Yolks: Let the potato mixture cool for a few minutes, then quickly stir in the egg yolks one at a time using a wooden spoon. If the mixture feels too thick, add the remaining 1 tablespoon of half and half to reach a smooth, pipeable consistency.
  8. Pipe into Domes: Fit a large piping bag with a 3/4-inch wide star tip and pipe the potato mixture onto the prepared baking sheet into 12 mounds, each approximately 2 1/2 inches wide by 2 1/2 inches tall. Alternatively, you can spoon the mixture instead of piping. Brush each mound gently with the remaining 2 tablespoons of melted butter.
  9. Bake: Bake the duchess potatoes in the preheated oven for 16 to 19 minutes or until they turn a beautiful golden brown color on top.
  10. Serve: Serve immediately, garnished with minced fresh parsley and extra grated parmesan cheese if desired.

Notes

  • Use Yukon gold potatoes for their creamy texture and rich flavor that works well in duchess potatoes.
  • Ensure potatoes are very tender and mashed smoothly for the best texture.
  • Be careful not to burn the garlic when sautéing; it should be lightly golden and fragrant.
  • If the potato mixture is too thick to pipe, add a bit more half and half, one teaspoon at a time.
  • Piping the potatoes creates a decorative look, but spooning is a fine alternative.
  • Serve duchess potatoes immediately for best texture; they are not ideal for reheating.
