Ingredients

Here are the simple ingredients you’ll need to create this fantastic Overnight Blueberry French Toast Casserole.

For the Casserole:

• 12 slices day-old bread, cut into 1-inch cubes (Italian bread works best I have found)
• 2 (8 ounce) packages cream cheese, cut into 1-inch cubes
• 1 cup fresh or frozen blueberries
• 12 eggs, beaten
• 2 cups whole milk
• 1 teaspoon vanilla extract
• ⅓ cup maple syrup

For the Blueberry Sauce:

• 1 cup white sugar
• 2 tablespoons cornstarch
• 1 cup water
• 1 cup fresh or frozen blueberries
• 1 tablespoon butter

Notes & Substitutions

Bread: Use a sturdy, day-old bread like Italian, brioche, or challah. As Reddit discussions highlight, stale bread prevents a soggy texture by absorbing the custard better. Avoid soft sandwich bread, which can fall apart.

Blueberries: Both fresh and frozen blueberries work beautifully in this recipe. If using frozen, there’s no need to thaw them beforehand. They will cook down nicely in the oven and sauce.

Milk: While whole milk provides the richest flavor and texture, feel free to use 2% or even skim milk if that’s what you have on hand. The casserole will still turn out delicious.

Cream Cheese: Ensure your cream cheese is softened to room temperature or whipped before cutting. This helps it melt evenly into the casserole without creating chunky pockets.

Sweeteners: Maple syrup adds a classic flavor to the custard. You can also use honey or brown sugar as alternatives for a slightly different sweet profile.

Equipment

Gathering your equipment beforehand makes the cooking process smooth and efficient. You will need a 9×13 inch baking dish for the casserole itself. A large mixing bowl is essential for whisking the egg custard. For the accompanying blueberry sauce, a medium saucepan is necessary. Don’t forget standard kitchen tools like a whisk, measuring cups, and measuring spoons to ensure accuracy.

Instructions

Creating this delightful Overnight Blueberry French Toast Casserole is simpler than you might think. Just follow these easy steps for a delicious, stress-free breakfast.

1. Prepare Baking Dish: Start by lightly greasing a 9×13 inch baking dish. This prevents the casserole from sticking and ensures easy serving later on.
2. Layer Bread and Filling: Arrange half of your bread cubes evenly across the bottom of the prepared dish. Next, distribute the cream cheese cubes over the bread layer. Sprinkle the first cup of blueberries over the cream cheese. Finally, top everything with the remaining bread cubes.
3. Make Egg Custard: In a large mixing bowl, whisk together the beaten eggs, whole milk, vanilla extract, and maple syrup until well combined. This mixture forms the rich base of your amazing French toast bake.
4. Soak Casserole: Pour the egg mixture evenly over the bread cubes in the baking dish. Gently press down the bread cubes with a spoon or spatula. This ensures they fully absorb the custard, becoming wonderfully “French toast-like” overnight.
5. Refrigerate Overnight: Cover the baking dish tightly with plastic wrap or foil. Place it in the refrigerator for at least a few hours, or ideally, overnight. This crucial step allows the bread to soak up all the flavorful custard.
6. Preheat Oven: About 30 minutes before you plan to bake, remove the casserole from the refrigerator to let it come closer to room temperature. Preheat your oven to 350°F (175°C).
7. Bake Casserole: Cover the casserole dish loosely with foil and bake for 30 minutes. Then, remove the foil and continue baking for another 25-30 minutes. The casserole is ready when the center is firm, and the surface is lightly browned and golden.
8. Prepare Blueberry Sauce: While the casserole bakes, prepare your luscious blueberry sauce. In a medium saucepan, combine the white sugar, cornstarch, and water. Bring this mixture to a boil over medium heat. Stir constantly for 3 to 4 minutes until it thickens slightly.
9. Finish Sauce: Stir in the remaining 1 cup of fresh or frozen blueberries. Reduce the heat to low and simmer for about 10 minutes, stirring occasionally, until the blueberries begin to burst and the sauce is rich. Remove the saucepan from the heat and stir in the tablespoon of butter until it’s fully melted and incorporated.
10. Serve: Once the casserole is baked and the sauce is ready, spoon generous amounts of the warm blueberry sauce over each serving of your delicious Overnight Blueberry French Toast Casserole. Enjoy it immediately!

Pro Tips for the Best Overnight Blueberry French Toast Casserole

• Use Stale Bread for Best Texture: Day-old or slightly stale bread is key. It absorbs the egg custard more efficiently without turning mushy, resulting in a perfect French toast consistency.
• Properly Soften or Whip Cream Cheese: Ensure your cream cheese is at room temperature or even whipped before adding it. This prevents lumps and helps it melt into creamy pockets throughout the casserole.
• Ensure Bread is Fully Saturated: Press down gently on the bread cubes after pouring the custard. This ensures every piece gets soaked, leading to a uniformly delicious and moist French toast bake.
• Don’t Overbake; Check for Firmness: Overbaking can lead to a dry casserole. Look for a lightly golden-brown top and a firm center. A knife inserted should come out mostly clean.
• The Blueberry Sauce is a Must-Add: While the casserole is fantastic on its own, the homemade blueberry sauce truly elevates this dish. It adds a burst of fresh fruit flavor and a lovely moisture that completes the experience.

Serving Suggestions, Storage, and Variations

Make your Overnight Blueberry French Toast Casserole an unforgettable meal with these easy suggestions!

Serving Suggestions

Elevate your breakfast or brunch with delightful toppings. A dollop of whipped cream or a dusting of powdered sugar adds elegance and sweetness. For an extra touch, serve individual portions with an additional drizzle of maple syrup. Pair this sweet casserole with savory sides like crispy bacon or flavorful sausage for a perfectly balanced and complete meal.

Storage & Reheating

Refrigerate: Any leftover casserole should be stored in an airtight container or covered tightly with plastic wrap in the refrigerator. It will stay fresh and delicious for about 3-4 days.

Freeze: You can freeze baked portions for longer storage, up to 1 month. Wrap individual servings tightly in plastic wrap and then foil to prevent freezer burn. Be aware that the texture of the cream cheese may alter slightly upon thawing.

Reheat: For individual servings, simply microwave until warmed through. To reheat larger portions, cover the casserole dish with foil and warm in a preheated oven at 300°F (150°C) until heated through, about 15-20 minutes.

Variations

Other Fruits: Feel free to get creative with your fruit choices! Instead of blueberries, try ripe raspberries, sliced strawberries, or even diced peaches for a different flavor profile.

Spices: Enhance the custard with warming spices. A pinch of cinnamon or nutmeg added to the egg mixture provides a cozy, aromatic touch.

Streusel Topping: For an added layer of texture and sweetness, sprinkle a simple brown sugar oat crumble over the casserole before baking. This creates a delightful crispy topping.
