Delicious Blueberry Lemon French Toast Casserole Overnight Recipe

This delightful casserole combines the sweetness of ripe blueberries with a zesty burst of lemon, making breakfast a celebration. Prepare it the night before for a warm, inviting morning treat.

Ingredients

Scale
  • 1012 cups day-old bread (brioche or challah preferred)
  • 2 cups fresh blueberries (or thawed frozen blueberries)
  • Zest of 2 lemons
  • Juice of 1 lemon
  • 8 large eggs
  • 2 cups whole milk (or almond/oat milk)
  • 1 cup maple syrup (or honey/agave syrup)
  • 1 teaspoon pure vanilla extract (or imitation vanilla)
  • 1 teaspoon cinnamon

Instructions

  1. Start by cutting your day-old bread into cubes.
  2. In a large bowl, whisk together 8 large eggs, 2 cups of milk, 1 cup of maple syrup, the zest of 2 lemons, and the juice of 1 lemon. Add 1 teaspoon of vanilla extract and a teaspoon of cinnamon. Mix until well combined.
  3. Place the cubed bread into a greased 9×13 inch baking dish. Pour the egg mixture evenly over the bread, making sure all the pieces are well coated. Gently fold in 2 cups of fresh blueberries.
  4. Cover the dish with plastic wrap and refrigerate overnight.
  5. The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes. Bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted comes out clean.
  6. Allow the casserole to cool slightly before serving. Drizzle with additional maple syrup and garnish with more fresh blueberries and a sprinkle of powdered sugar, if desired.
