Blueberry French Toast Casserole Ingredients
For the Casserole
- French Bread – This sturdy bread absorbs all the flavors beautifully; day-old bread is ideal for soaking.
- Cream Cheese (8 oz) – The star of the dish, adding a rich and creamy texture; Philadelphia brand is recommended for best results.
- Powdered Sugar (1 cup) – Provides necessary sweetness to the cream cheese mixture; no substitutes recommended for this perfect flavor.
- Vanilla Extract (1 tbsp) – This elevates the dish’s overall taste; feel free to swap for almond extract for a different twist.
- Milk (2 cups, whole preferred) – Contributes creaminess to your egg mixture; while whole milk is best, any milk can work.

- Cinnamon (1 tsp) and Nutmeg (1/2 tsp) – This classic spice blend adds warmth and depth of flavor to the dish.

Step‑by‑Step Instructions for Blueberry French Toast Casserole
Step 1: Prepare the Cream Cheese Mixture
In a mixing bowl, combine 8 ounces of softened cream cheese, 1 cup of powdered sugar, 2 cups of whole milk, and 1 tablespoon of vanilla extract. Use a hand mixer or whisk vigorously until the mixture is smooth and creamy, with no lumps. Then, gently fold in 1 cup of fresh blueberries, ensuring they are well distributed to create bursts of flavor throughout your Blueberry French Toast Casserole.
Step 2: Layer the Bread
Take a 10×14-inch baking dish and apply a thin layer of butter to prevent sticking. Next, cube your day-old French bread into bite-sized pieces and layer them evenly across the bottom of the dish. This sturdy layer provides the perfect foundation for soaking up the flavors of the creamy mixture. Ensure the bread is well spread without any gaps, setting the stage for a rich and satisfying texture.
Step 3: Spread the Cream Cheese Mixture
With your cream cheese mixture ready, pour it over the layer of cubed bread, using a spatula to evenly spread it out. Ensure that all the bread cubes are covered in the luscious cream cheese blend, so each piece gets soaked and infused with flavor. This layering is key to achieving that gooey and rich center in your Blueberry French Toast Casserole.
Step 4: Add More Bread Cubes
Top the cream cheese-covered bread with the remaining cubes of French bread. This second layer will help balance the richness of the casserole. Press down gently to ensure the bread stays in contact with the cream cheese mixture, which is crucial for soaking up all the delightful flavors. Set this aside while you prepare the egg mixture.
Step 5: Create the Egg Mixture
In a separate large bowl, whisk together 8 large eggs, 2 cups of whole milk, 1 tablespoon of vanilla extract, 1 teaspoon of cinnamon, and ½ teaspoon of nutmeg until fully blended and pale in color. This mixture will bind your casserole together while adding warmth and spice. Once combined, pour the egg mixture evenly over the layered bread, making sure to cover all the pieces.
Step 6: Soak the Casserole
After pouring the egg mixture, gently press down on the bread to help it absorb the liquid fully. Next, sprinkle the remaining 1 cup of fresh blueberries on top for added sweetness and a pop of color. Cover the dish tightly with aluminum foil to ensure it remains moist during soaking, and refrigerate for at least 8 hours or overnight for the best flavor infusion, allowing all the ingredients to meld beautifully.
Step 7: Preheat and Bake
When you’re ready to bake your Blueberry French Toast Casserole, preheat your oven to 375°F (190°C). Once the oven is ready, remove the foil from the dish, exposing the beautiful layered bread and blueberries. Baking it covered for the first 45 minutes will allow the casserole to set before achieving that golden-brown finish.
Step 8: Final Baking and Serving
Continue baking uncovered for an additional 30 minutes, or until the top is lightly browned and the center is set. This final step creates a lovely crispy edge with a soft, gooey center. Once baked, allow your casserole to cool slightly before slicing it into generous portions. Serve warm, perhaps with a light dusting of powdered sugar or a delightful drizzle of syrup for an added touch of sweetness.

Expert Tips for Blueberry French Toast Casserole
-
Bread Choice Matters: Use day-old French bread for optimal soaking. Fresh bread can be dried slightly but may not absorb flavors as well.

Proper Soaking Time: Allow your casserole to soak in the fridge for at least 8 hours. This step is crucial for the best texture in your Blueberry French Toast Casserole.
-
Avoid Overcrowding: Ensure the bread cubes are spread evenly in the baking dish to prevent uneven cooking and ensure every scoop is delicious.
-
Check for Doneness: The casserole should be lightly browned and set in the center before removing from the oven. Adjust baking time based on your oven.

What should I do if the casserole is too dry after baking?
If you find your casserole is dry, it might be due to not enough soaking time. Ensure you refrigerate it for at least 8 hours, preferably overnight, to allow full absorption. If you have leftover casserole, consider drizzling it with syrup or a fruit sauce to add moisture!
