Ingredients

  • 2 large onions, thinly sliced
  • 2 tablespoons butter
  • 1 cup half-and-half cream
  • 1 cup canned pumpkin
  • 1 tablespoon prepared horseradish
  • 1/2 teaspoon ground nutmeg
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 2-1/4 pounds potatoes, peeled and cut into 1/4-inch slices
  • 2 cups soft bread crumbs
  • 8 ounces Gruyere or Swiss cheese, shredded
  • 2 tablespoons chopped fresh sage

Directions

  1. In a large skillet, cook onions in butter over medium heat for 15-20 minutes or until onions are golden brown, stirring frequently.
  2. In a large bowl, combine the half-and-half, pumpkin, horseradish, nutmeg, salt and pepper. In a greased 13x9-in. baking pan, layer potato slices and onions. Spread with pumpkin mixture. Cover and bake at 350° for 1-1/4 hours.
  3. Increase temperature to 400°. In a large bowl, combine the bread crumbs, cheese and sage. Sprinkle over top. Bake, uncovered, 15-20 minutes longer or until golden brown.
Soft Bread Crumbs
To make soft bread crumbs, tear bread into pieces and place in a food processor or blender. Cover and pulse until crumbs form. One slice of bread yields 1/2 to 3/4 cup crumbs.
