Ingredients

  • 2 cups dried potatoes, slices
  • 3 chicken bouillon cubes
  • 5 cups water, plus 2 cups cold water
  • 1/4 cup dried tomatoes, pieces
  • 2 tablespoons shredded dried carrots
  • 2 tablespoons dried green beans (1-inch pieces)
  • 1 tablespoon dried bell pepper, pieces
  • 1 tablespoon dried mushroom pieces
  • 1 tablespoon dried onion, pieces
  • 1/4 teaspoon dried basil
  • 1/4 teaspoon dried oregano
  • 1/4 teaspoon chopped garlic
  • 1/4 teaspoon dried mustard
  • 1/4 teaspoon dried celery powder
  • 1/4 teaspoon celery seed
  • 2 cups cold water
  • 1/2 cup instant milk
  • 1 cup dried potato flakes (store-bought or homemade, see note below)
  • freshly grated parmesan cheese

Method

  • In a soup kettle, combine the dried potato slices, bouillon, and 5 cups water. Let sit about 5 minutes to absorb some of the liquid. Add the dried tomatoes, carrots, green beans, peppers, mushrooms, onions, and all the seasonings. Bring the mixture to a boil over high heat. Remove the kettle from the heat, cover, and let sit for at least 15 minutes to rehydrate.
  • Return the kettle to the heat, bring the soup to a boil, and let it simmer slowly, stirring occasionally, for at least 1 hour until the vegetables are soft, adding water if necessary.
  • In a pitcher, stir together the 2 cups cold water and the dry milk. Bring the soup to a boil and stir in the milk. Reduce the heat to low and gradually stir in the potato flakes. Stir constantly, to prevent the soup from scorching, for about 5 minutes. Top with Parmesan cheese before serving.
  • Homemade Potato Flakes: Spread cooked mashed potatoes on lightly oiled leather sheets, place in the dehydrator, and dry. Break the sheets into chunks, put in the blender, and pulse until ground into flakes.
