Step-by-Step Instructions for Overnight Blueberry French Toast Casserole

Prepare the Cream Cheese Mixture
In a bowl, mix 8 ounces of softened cream cheese, 1 cup powdered sugar, 2 tablespoons of milk, and 1 tablespoon vanilla extract. Whisk until smooth, then gently fold in 1 cup of blueberries.
Assemble the Bread Layers
Cube 2 loaves of French bread and layer the bottom of a 10×14-inch baking dish with half of the bread cubes. Spread the cream cheese mixture evenly over the bread, then top with the remaining bread cubes.
Prepare the Egg Mixture
Whisk together 2 cups of milk, 8 eggs, 1 teaspoon of cinnamon powder, and ½ teaspoon of ground nutmeg. Pour this mixture over the layered bread, ensuring all the bread is soaked. Top with another cup of blueberries.
Refrigerate Overnight
Cover the dish tightly with foil and refrigerate for 8 hours or overnight. This allows the bread to soak up the custard mixture fully.
Preheat the Oven
Preheat your oven to 375°F (190°C) for baking.
Bake the Casserole
Bake the casserole for 45 minutes with the foil on. Then, remove the foil and continue baking for another 30 minutes until the top is golden brown and the center is set.
Serve and Enjoy
Let the casserole cool for a few minutes before serving. It’s perfect with a drizzle of maple syrup and a side of crispy bacon or fresh fruit.

Tips & Tricks for the Best Blueberry French Toast Casserole

Don’t Overbake: Keep an eye on the casserole as it bakes. It should be golden and slightly puffed, with the center set but soft.
Let It Rest: After baking, let the casserole rest for 10 minutes. This allows it to firm up while staying moist and creamy.
Storage: Leftovers can be stored in the fridge for up to 3 days, and they actually taste even better the next day as the flavors meld. You can also freeze the casserole, either unbaked or baked, for up to 2 months.
