Easy French Toast Casserole (Make-Ahead Breakfast Bake)


  • Author: WAFA LI

Ingredients

Scale

For the casserole:

  • 1 loaf (16 oz / 450g) brioche or challah bread, cut into 1” cubes
  • 6 large eggs
  • 2 cups whole milk
  • ½ cup heavy cream
  • ½ cup granulated sugar
  • 2 tsp vanilla extract
  • 1 tsp ground cinnamon
  • Pinch of salt

Optional add-ins:

  • 1 cup fresh berries (blueberries, raspberries)
  • ½ cup chopped pecans or walnuts
  • 1 tsp orange zest

For topping (choose one):

  • Streusel: ¼ cup flour + ¼ cup brown sugar + 2 tbsp cold butter + ½ tsp cinnamon
  • Simple finish: Powdered sugar + maple syrup

Instructions

  1. Prep: Grease a 9×13″ baking dish. Place bread cubes in dish (add berries/nuts if using).
  2. Make custard: In a bowl, whisk eggs, milk, cream, sugar, vanilla, cinnamon, and salt until smooth.
  3. Soak: Pour custard over bread. Press down gently to submerge. Cover and refrigerate at least 4 hours, preferably overnight.
  4. Preheat oven to 350°F (175°C).
  5. Add streusel (if using): Mix streusel ingredients; sprinkle over top.
  6. Bake 45–55 minutes, until puffed, golden, and center is set (165°F internal temp).
  7. Cool 10 minutes before serving. Dust with powdered sugar or drizzle with maple syrup.
💡 Pro Tips:
– Use stale bread for best texture—it soaks up custard without turning mushy.
– For extra richness, swap half the milk with eggnog during the holidays!
– Make it gluten-free: use GF bread and check all labels.
