  • 1 loaf stale bread
  • 5 whole organic cage-free eggs
  • 2 organic cage-free egg whites
  • 1 cup nonfat vanilla Greek yogurt
  • 1 cup low-fat milk
  • ¾ cup 100 percent pure maple syrup
  • 2 tablespoons cold butter diced
  • cup unrefined brown sugar packed
  • 1 teaspoon ground cinnamon
  • ¼ cup all-purpose flour
  • ¼ cup minced pecans optional


  • Spray a 9" × 13" casserole dish with organic nonstick cooking spray.
  • 2. Tear bread into pieces and spread them throughout the casserole dish in an even layer.
  • 3. In a large bowl, mix eggs, egg whites, Greek yogurt, milk, and maple syrup. Mix very well until smooth and thoroughly combined. Pour egg mixture completely over bread.
  • 4. In a small bowl, mix butter, brown sugar, cinnamon, flour, and pecans, if using. Mix until all ingredients are combined, even if still lumpy.
  • 5. Sprinkle the butter mixture on top of the bread. Cover and refrigerate overnight. If cooking the same day, make sure to refrigerate at least 30 minutes before baking.
  • 6. In the morning, preheat the oven to 350°F. Bake for 45 minutes until golden brown and the middle of the dish is set. Serve immediately with maple syrup, if desired.
