The Ingredients

  • 3 pounds Yukon gold potatoes, cut into 2-inch pieces
  • 7 cups chicken broth
  • 1 tablespoon table salt
  • 7 tablespoons unsalted butter
  • 1 teaspoon granulated garlic
  • 1 tablespoon fresh thyme, minced
  • 1 tablespoon fresh rosemary, minced
  • 1 teaspoon black pepper
  • 1 cup half and half
  • 1/2 cup Gruyere cheese, freshly grated
  • 2 tablespoons chives, finely chopped

Cook the Potatoes

Peel and cut potatoes into 2-inch pieces. Keep them uniform so they cook evenly.

Put them in a large pot and cover with chicken broth. Bring to a simmer over medium-high, then reduce to maintain gentle bubbles.

Cook ~20 minutes until fork-tender but not falling apart. Drain well and return to the hot pot for ~1 minute. This steams off extra moisture.

Make Herb Butter

While potatoes cook, melt butter in a small saucepan over medium heat.

Add salt, pepper, granulated garlic, rosemary, and thyme. Keep warm ~5 minutes to infuse the flavors. Turn down if it bubbles hard.

Rice and Mix

Push the hot potatoes through a ricer back into the warm pot. Hot potatoes rice easier and won’t get gluey.

Add the herb butter and half and half. Fold gently with a rubber spatula until just combined.

Fold in the Gruyere carefully. Taste and add salt if needed.

Serve

Top with chives right before serving.

Keep them hot – cold mashed potatoes are sad mashed potatoes.

The chicken broth adds way more flavor than water. That drying step after draining is crucial – skip it and they’ll be watery. A ricer is worth buying if you make mashed potatoes more than twice a year. Reheat leftovers with a splash of half and half to loosen them up.
