Printer-friendly version

Ingredients

  • 4 pounds baking potatoes
  • 2 teaspoons salt
  • 1 1/4 cups warm buttermilk
  • 1/2 cup warm milk
  • 1/4 cup melted butter
  • 1/2 teaspoon pepper
  • 1 teaspoon salt
  • 1 1/4 cups freshly grated Gruyère cheese
  • 1 cup chopped caramelized onion
  • 2 tablespoons chopped fresh parsley

Preparation

1. Peel potatoes; cut into 2-inch pieces. Bring potatoes, 2 tsp. salt, and water to cover to a boil in a large Dutch oven over medium-high heat; boil 20 minutes or until tender. Drain. Return potatoes to Dutch oven, reduce heat to low, and cook, stirring occasionally, 3 to 5 minutes or until potatoes are dry.

2. Mash potatoes with a potato masher to desired consistency. Stir in warm buttermilk, warm milk, melted butter, pepper, and 1 tsp. salt, stirring just until blended.

3. Stir in Gruyère cheese, caramelized onions, and parsley, and spoon the mixture into a lightly greased 2 1/2-qt. baking dish or 8 (10-oz.) ramekins. Bake at 350° for 35 minutes.
