Equipment

  • Vegetable peeler
  • Chef's knife
  • Cutting Board
  • large pot
  • Small saucepan
  • Colander
  • Potato masher or potato ricer
  • Measuring cups and spoons

Ingredients

  • 2 large russet potatoes (~1.5 lbs)
  • 4 medium Yukon Gold potatoes (~1.5 lbs)
  • 4 tbsp salted butter
  • 4 garlic cloves smashed
  • 2 fresh rosemary sprigs
  • 2 fresh thyme sprigs
  • 1/4 cup heavy cream
  • 1/4 cup milk
  • salt to taste, plus 1 tablespoon
  • black pepper to taste

Instructions

  • Prepare and boil the potatoes. Wash and peel the potatoes, then cut them into approximately 2- to 3-inch cubes, keeping the pieces as even in size as possible. Place the potatoes in a large pot and add enough cool water to completely cover them. Add 1 tablespoon of salt, then bring to a boil over medium-high heat. Cook until the potatoes are fork-tender but not falling apart. Drain well.
  • Infuse the butter and cream. While the potatoes are boiling, add the butter, smashed garlic cloves, rosemary, thyme, heavy cream, and milk to a small saucepan. Bring to a very gentle simmer over low heat, allowing the garlic and herbs to infuse the mixture as it warms. Do not allow the cream to boil.
  • Mash the potatoes. Remove the rosemary, thyme, and garlic from the warm butter and cream mixture. Using a potato masher, mash the drained potatoes while gradually adding the warm butter and cream mixture until the potatoes reach your desired consistency.
  • Season and serve. Season the mashed potatoes to taste with salt and black pepper. Serve warm.

Notes

Alternative Ricer Method
For smoother, lighter mashed potatoes, pass the drained potatoes through a potato ricer instead of using a masher. Gradually fold in the warm infused butter and cream mixture, then season with salt and black pepper to taste.
Recipe Notes
  • Cut the potatoes evenly: Keeping the potato pieces close to the same size helps them cook at the same rate.
  • Start with cool water: This allows the potatoes to heat gradually and cook more evenly.
  • Don't overcook the potatoes: Cook just until fork-tender. Potatoes that absorb too much water can become heavy or watery when mashed.
  • Keep the cream mixture warm: Adding warm dairy to warm potatoes helps everything incorporate smoothly.
  • Add the liquid gradually: Depending on the size and moisture content of your potatoes, you may not need to add the entire mixture at once.
  • Don't overwork the potatoes: Mash only until you reach your desired consistency. Excessive mixing can make mashed potatoes gummy.
Adjust the consistency if needed: For softer mashed potatoes, add another small splash of warm milk or heavy cream before serving.
