Ingredients List for Blueberry Lemon French Toast Casserole Overnight Recipe

1 (8 oz) cream cheese
1 cup powdered sugar
2 tbsp milk
1 tbsp vanilla extract
2 cups blueberries
2 loaves French bread, cubed
2 cups milk
8 large eggs
1 tsp cinnamon
½ tsp nutmeg
1 lemon (zest + 2 tbsp juice)

How To Make Blueberry Lemon French Toast Casserole Overnight Recipe Step-by-Step

Step 1: Make the Cream Cheese Mixture

Start by mixing the cream cheese, powdered sugar, 2 tbsp of milk, and 1 tsp of vanilla extract until smooth. Fold in 1 cup of blueberries along with 1 tbsp of lemon juice and a little lemon zest to bring brightness to the mixture.

Step 2: Layer the Bread

Take your greased 10×14” dish and layer half of the cubed French bread at the bottom. Spread the cream cheese mixture evenly over this layer, ensuring each piece of bread gets a taste.

Step 3: Add the Remaining Bread

Pour the remaining bread cubes on top of the cream cheese layer to create a hearty base for your casserole.

Step 4: Prepare the Egg Mixture

In a separate bowl, whisk together 2 cups of milk, the eggs, 2 tsp of vanilla extract, cinnamon, nutmeg, the remaining lemon zest, and 1 tbsp of lemon juice. This mixture will infuse the bread with flavor as it cooks.

Step 5: Combine the Layers

Pour the egg mixture over the layered bread carefully, ensuring you cover all pieces to maximize absorption. Sprinkle any remaining blueberries on top for a burst of color and flavor.

Step 6: Chill Overnight

Cover the casserole dish with foil and place it in the refrigerator to chill overnight. This step allows the flavors to meld beautifully and the bread to soak up the custard.

Step 7: Bake the Casserole

Preheat your oven to 375°F. Bake the casserole covered with foil for about 45 minutes. After that, remove the foil and bake for an additional 30 minutes, or until the top is golden brown and set.
