How to Make Blueberry French Toast Casserole
Follow these straightforward steps for perfect results every time. The key lies in proper layering and patience during the overnight rest.
Step 1: Prepare Cream Cheese Filling
Beat softened cream cheese, powdered sugar, milk, and vanilla bean paste until smooth. Gently fold in one cup blueberries, being careful not to crush berries.
Step 2: Assemble the Base
Spread half the bread cubes in a greased 9×13 baking dish. Dollop cream cheese mixture over bread, then top with remaining bread. Sprinkle remaining blueberries evenly across the top layer.
Step 3: Create Custard Mixture
Whisk together eggs, milk, cinnamon, nutmeg, and remaining vanilla bean paste. Pour evenly over bread layers, pressing down gently to ensure full saturation.
Step 4: Overnight Rest
Cover tightly with plastic wrap and refrigerate 8-12 hours. This crucial step allows flavors to meld and bread to absorb custard completely.
Step 5: Bake to Perfection
Preheat oven to 350°F (175°C). Remove wrap, bake uncovered 60-75 minutes until golden brown and center sets. For extra crunch, finish with 3 minutes under broiler.
