Ingredients

Scale

Main Ingredients

  • 1214 cups French bread, cubed
  • 8 large eggs
  • 2 cups 2% milk
  • 2 tsp vanilla extract
  • 1 tsp cinnamon
  • 2/3 cup brown sugar

Toppings

  • 1 cup strawberries, sliced
  • 1/2 cup blueberries
  • 12 tbsp powdered sugar
  • Maple syrup, as desired

Instructions

  1. Prepare the Baking Dish: Grease a 9″x13″ casserole dish with vegetable oil or butter to prevent sticking and enhance flavor.
  2. Add Bread Cubes: Cut French bread into cubes and fill the casserole dish about three-quarters full for a good bread-to-custard ratio.
  3. Mix Custard: In a large bowl, whisk together eggs, 2% milk, vanilla extract, cinnamon, and brown sugar until well combined to create a flavorful custard base.
  4. Combine Bread and Custard: Pour the custard mixture evenly over the bread cubes in the casserole dish, allowing the bread to soak up the liquid.
  5. Add Fresh Berries: Slice strawberries and scatter them along with blueberries evenly over the soaked bread mixture.
  6. Refrigerate: Cover the casserole tightly with saran wrap and refrigerate for at least four hours or up to overnight to let the flavors meld and the bread absorb the custard fully.
  7. Preheat Oven: Set your oven to 350°F (175°C) so it’s ready once the casserole is removed from refrigeration.
  8. Bake: Remove plastic wrap and bake the casserole for 35 to 50 minutes. Begin checking at 35 minutes; the top should be golden brown and set when done.
  9. Finish and Serve: Once baked, sprinkle the casserole with powdered sugar for a touch of sweetness. Serve warm with maple syrup poured over each serving for indulgence and added flavor.

Notes

  • For best flavor and texture, allow the casserole to rest in the refrigerator overnight.
  • You can substitute French bread with brioche or challah for a richer taste.
  • If using frozen berries, thaw and drain excess liquid to avoid soggy casserole.
  • Maple syrup adds sweetness but can be omitted or substituted with honey or fruit syrup.
  • Ensure the casserole is baked until fully set; undercooked custard will be runny.
