  • 10 ounces baby spinach
  • 6 cups ½-inch artisan whole-grain bread cubes
  • 8 ounces semi-skim Swiss or Jarlsberg cheese, grated
  • 6 eggs, divided
  • cups milk or milk substitute
  • ¼ teaspoon nutmeg
  • teaspoons salt
  • ½ teaspoon ground pepper
  • ¼ teaspoon cream of tartar


  • Preheat oven to 375°. Grease soufflé dish well.
  • Place spinach in a large skillet with ¼ cup water. Steam until spinach is wilted. Drain, and chop finely. Set aside.
  • Toss bread cubes and cheese in a large bowl.
  • Divide 2 eggs into whites and yolks. Whisk the 2 yolks with 4 whole eggs, milk, nutmeg, salt, pepper and spinach. Pour over bread, and let sit 30 minutes. 
  • When a half-hour has passed, gently stir bread and egg mixture. Whip 2 egg whites with cream of tartar and a pinch of salt until stiff peaks form. 
  • Fold in 1/3 of egg whites into bread mixture. Gently fold in remaining egg whites until all whites are incorporated.
  • Pour into greased baking dish. Bake 1 hour, plus 10–15 minutes until the center is just set. If top browns too much, cover with a loose foil tent.
  • Serve immediately.
