Mashed Potato Casserole
Serves: 6
  • 2½ pounds boiling potatoes, unpeeled
  • Salt
  • 3 tablespoons olive oil
  • 2 medium onions, chopped
  • 8 ounces small mushrooms, quartered
  • Pepper
  • ¼ cup vegetable broth, chicken broth, dairy-free milk alternative, or pureed tofu
  • 2 large eggs, beaten
  • ½ teaspoon paprika
  1. Put potatoes in a large saucepan with water to cover and a pinch of salt and bring to a boil. Cover and simmer over low heat for 35 minutes or until very tender. Drain and leave until cool enough to handle.
  2. In a big skillet, heat oil or butter, add onion; saute over medium heat until light golden. Add mushrooms and salt and pepper to taste, and saute over medium-high heat for 7 minutes or until brown. Set aside.
  3. Peel potatoes if desired. Put in big bowl, cut each in a few pieces and beat with a mixer at low speed until coarsely mashed. Beat in broth or milk alternative. Beat in the eggs, just until blended. Stir in ½ cup of reserved mushroom mixture. Add ¾ teaspoon salt and ½ teaspoon pepper, or to taste.
  4. Grease a 6- or 7-cup casserole and add half of potato mixture. Top with remaining mushroom mixture, then with remaining potato mixture. Smooth top and sprinkle with paprika. Bake in preheated 350-degree oven uncovered for 50 minutes, or until top is firm and light golden at edges.
