Ingredients

  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 1 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/8 teaspoon ground nutmeg
  • 2 cans (12 ounces each) evaporated milk
  • 1 cup water
  • 7 medium potatoes (about 2 pounds), peeled and sliced
  • 4 cups sliced peeled butternut squash (about 1 pound)
  • 1/4 cup minced fresh chives
  • 2 cups shredded Swiss cheese

Directions

  1. Preheat oven to 400°. In a Dutch oven, melt butter over medium heat. Stir in flour, salt, pepper and nutmeg until smooth; gradually whisk in milk and water. Stir in potatoes, squash and chives. Bring to a boil. Reduce heat; simmer, uncovered, 8-10 minutes or until potatoes and squash are almost tender.
