The Best Blueberry French Toast Casserole You’ll Ever Make


  • Author: Jessica

Ingredients

Scale

Essential Ingredients:

  • 1 loaf of brioche or challah bread, cubed
  • 6 large eggs
  • 2 cups milk (whole or 2%)
  • 2 teaspoons vanilla extract
  • 1 teaspoon cinnamon
  • 1½ cups fresh blueberries
  • Butter (for greasing the baking dish)

Instructions

  1. Prepare the Baking Dish:
    Grease a 9×13-inch baking dish with butter to prevent sticking.
  2. Prepare the Bread Base:
    Cut the loaf of bread into cubes and spread them evenly in the prepared dish.
  3. Make the Egg Mixture:
    In a large mixing bowl, whisk together the eggs, milk, vanilla extract, and cinnamon until fully combined.
  4. Combine and Layer:
    Pour the egg mixture evenly over the bread cubes, making sure every piece is well-soaked. Sprinkle the fresh blueberries over the top.
  5. Let It Soak:
    Allow the casserole to sit for at least 30 minutes, or cover and refrigerate overnight for deeper flavor and easier preparation.
  6. Bake:
    Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 45-50 minutes, or until the top is golden brown and the inside is set.
  7. Serve:
    Remove from the oven and let cool slightly before serving. Pair with powdered sugar, maple syrup, or whipped cream for an extra indulgent touch.
