Method
 

Overnight French Toast Casserole, Made Easy
  1. Cut your challah or brioche loaf into 1-inch cubes. Place the cubes evenly into your 9x13-inch baking dish.
  2. In a large mixing bowl, whisk together the eggs, whole milk, maple syrup, vanilla extract, ground cinnamon, salt, and brown sugar until well combined and smooth.
  3. Pour the custard mixture evenly over the bread cubes in the baking dish. Press down lightly to ensure the bread absorbs the custard fully. Cover tightly with plastic wrap or a lid, then refrigerate overnight or at least 6 hours.
  4. Preheat oven to 350°F (175°C). Sprinkle chopped walnuts or pecans on top of the soaked bread. If using turkey bacon, cook until crispy, then crumble over casserole.
  5. Bake uncovered for 45 to 55 minutes, until the top is golden brown and custard is set. The edges will be slightly crisp.
  6. Let casserole cool for a few minutes before slicing. Serve warm with extra maple syrup or fresh fruit if desired.

Notes

  • Use almond or oat milk for a dairy-free version.
  • Omit nuts or use seeds for a nut-free alternative.
  • Add fresh berries or sliced apples before baking for extra flavor and texture.
  • Store leftovers covered in the fridge up to 3 days or freeze up to 2 months.
  • Reheat in the oven at 350°F for about 20 minutes or microwave individual portions.
