How to Make Blueberry Lemon French Toast Casserole Overnight Recipe
Step 1: Prepare the Cream Cheese Mixture
Start by mixing together your cream cheese, powdered sugar, milk, and vanilla extract until it’s smooth and creamy. This step is essential because it creates that luscious filling that will bring your casserole to life! Once combined, gently fold in 1 cup of blueberries along with 1 tablespoon of lemon juice and some zest — this adds bursts of flavor throughout.
Step 2: Layer Your Ingredients
In a greased 10×14 inch dish, layer half of your cubed French bread. Next, spread your creamy mixture evenly over the bread cubes. Then add the remaining bread on top. The layering helps ensure every piece gets soaked with that delicious custard later on!
Step 3: Whisk Together Custard Ingredients
In a large bowl, whisk together your milk, eggs, vanilla extract, cinnamon, nutmeg, remaining lemon zest, and another tablespoon of lemon juice. This custard mixture is key as it saturates the bread overnight making it soft yet perfectly set after baking.
Step 4: Pour Over Bread
Pour your custard mixture evenly over the layered bread in your dish. Finally, sprinkle any leftover blueberries on top for those lovely pops of flavor peeking through when baked.
Step 5: Chill Overnight
Cover your casserole tightly with foil and place it in the fridge overnight. Allowing it to chill gives those flavors time to meld beautifully!
Step 6: Bake Until Golden
When you’re ready to bake, preheat your oven to 375°F (190°C). Bake covered for 45 minutes until it’s set. Then remove the foil and bake for an additional 30 minutes until golden brown. The result? A dreamy breakfast casserole that’s warm and inviting!
Pro Tips for Making Blueberry Lemon French Toast Casserole Overnight Recipe
Creating the perfect Blueberry Lemon French Toast Casserole is all about the little details! Here are some tips to ensure your dish turns out perfectly every time.
- Use day-old bread: Stale bread absorbs the custard mixture better, giving you that soft, creamy texture without becoming soggy.
- Let it chill overnight: Allowing the casserole to sit in the fridge overnight helps the flavors meld together beautifully, creating a more delicious final dish.
- Experiment with spices: Feel free to add a pinch of cardamom or ginger for an extra layer of flavor. Spices can elevate your casserole and bring warmth to each bite.
- Adjust sweetness: If you prefer a sweeter dish, consider adding a bit more powdered sugar or using flavored cream cheese. Balancing sweetness will make it more enjoyable for everyone at the breakfast table.
- Top it off before serving: A light dusting of powdered sugar or a drizzle of maple syrup just before serving can add an appealing touch and enhance the overall presentation.
