  • 4 pounds Yukon Gold potatoes, peeled and cubed (about 8 cups)
  • 1/2 cup butter, softened
  • 1-1/4 teaspoons salt
  • 1/4 teaspoon pepper
  • 3/4 to 1 cup buttermilk
  • Optional toppings: crumbled cooked bacon, sour cream and thinly sliced green onions


  1. Place potatoes in a 6-qt. stockpot; add water to cover. Bring to a boil. Reduce heat; cook, uncovered, until tender, 10-15 minutes.
  2. Drain; return to pan. Mash potatoes, gradually adding butter, salt, pepper and enough buttermilk to reach desired consistency. Serve with toppings as desired.
To substitute for each cup of buttermilk, use 1 Tbsp. white vinegar or lemon juice plus enough milk to measure 1 cup. Stir, then let stand 5 min. Or, use 1 cup plain yogurt or 1-3/4 teaspoon cream of tartar plus 1 cup milk.
