Ingredients

  • 1 loaf cinnamon brioche bread I used a 14.1-ounce loaf of brioche bread.
  • ½ cup butter melted
  • 6 large eggs
  • 1 teaspoon salt
  • 1-¼ cups whole milk
  • 2 teaspoons vanilla extract
  • ¼ cup all purpose flour
  • ¼ cup brown sugar
  • ¼ cup chopped pecans
  • Butter, powdered sugar and/or maple syrup for serving.

Instructions

  • Spray a 9x13 baking dish with non-stick cooking spray.
  • Dice the bread loaf into 1-2” pieces and place in a large mixing bowl.
  • In a separate bowl, add the eggs, salt, milk, and vanilla. Whisk to combine. Add the melted butter, mix again.
  • Pour the egg mixture over the bread. Using a large spoon, mix so the bread is evenly coated.
  • Pour the bread/egg mixture into the prepared casserole dish. Cover with plastic wrap. Refrigerate preferably, overnight (or at least 2 hours).
  • The next day, preheat the oven to 350°F. Remove plastic wrap from the casserole dish.
  • In a small bowl, mix flour with ¼ cup brown sugar. Sprinkle over the top of the casserole.
  • Bake, uncovered in the oven for 45-50 minutes.
  • Remove and allow to sit for 10 minutes. Slice and serve with butter, powdered sugar and syrup.
