## Ingredients You’ll Need

Before you start, gather these simple ingredients:

* **Bread:** 1 loaf of challah, brioche, or French bread, cut into 1-inch cubes. These breads have a slightly sweet and rich flavor that complements the custard perfectly. Day-old bread works best, as it will absorb the custard better without becoming soggy.
* **Eggs:** 8 large eggs. Eggs are the foundation of the custard and provide structure and richness to the casserole.
* **Milk:** 2 cups of whole milk. Whole milk contributes to the creamy texture of the custard. You can substitute with 2% milk or almond milk for a lighter option, but the texture may be slightly different.
* **Heavy Cream:** 1 cup of heavy cream. Heavy cream adds richness and decadence to the custard, creating a truly indulgent breakfast.
* **Granulated Sugar:** 1/2 cup of granulated sugar. Sugar sweetens the custard and balances the tartness of the blueberries. You can adjust the amount of sugar to your liking, depending on your preferred level of sweetness.
* **Vanilla Extract:** 2 teaspoons of vanilla extract. Vanilla extract enhances the flavor of the custard and adds a warm, comforting aroma.
* **Ground Cinnamon:** 1 teaspoon of ground cinnamon. Cinnamon adds a warm, spicy note to the casserole that complements the blueberries perfectly.
* **Salt:** 1/4 teaspoon of salt. Salt enhances the flavors of the other ingredients and balances the sweetness.
* **Blueberries:** 2 cups of fresh or frozen blueberries. Blueberries add a burst of juicy sweetness to the casserole. If using frozen blueberries, do not thaw them before adding them to the casserole.
* **Optional Toppings:** Powdered sugar, maple syrup, whipped cream, chopped nuts, or a streusel topping for serving.

## Equipment You’ll Need

* 9×13 inch baking dish
* Large mixing bowl
* Whisk
* Measuring cups and spoons
* Spatula

## Step-by-Step Instructions

Here’s how to make this delightful Overnight Blueberry French Toast Casserole:

**Step 1: Prepare the Bread**

* Cut the bread into 1-inch cubes. You can use a serrated knife for easier cutting. Make sure to remove the crust if you prefer a softer texture.
* Spread the bread cubes evenly in the prepared baking dish.

**Step 2: Make the Custard**

* In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined. Ensure that the sugar is fully dissolved.

**Step 3: Assemble the Casserole**

* Pour the custard mixture evenly over the bread cubes in the baking dish. Use a spatula to gently press the bread down into the custard, ensuring that all the bread is soaked.
* Sprinkle the blueberries evenly over the bread and custard mixture. If using frozen blueberries, add them directly from the freezer without thawing.

**Step 4: Refrigerate Overnight**

* Cover the baking dish tightly with plastic wrap or aluminum foil. This will prevent the casserole from drying out in the refrigerator.
* Refrigerate the casserole for at least 8 hours, or preferably overnight. This allows the bread to fully absorb the custard and the flavors to meld together.

**Step 5: Bake the Casserole**

* Preheat your oven to 350°F (175°C).
* Remove the casserole from the refrigerator and let it sit at room temperature for about 30 minutes. This will help the casserole bake more evenly.
* Uncover the baking dish and bake the casserole for 45-55 minutes, or until the top is golden brown and the custard is set. The center of the casserole should be firm to the touch.
* If the top of the casserole starts to brown too quickly, you can tent it with aluminum foil during the last 15-20 minutes of baking.

**Step 6: Let it Rest and Serve**

* Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This will allow the custard to set further and make it easier to slice.
* Dust the casserole with powdered sugar, if desired.
* Serve warm with maple syrup, whipped cream, chopped nuts, or your favorite toppings.

## Tips for the Perfect Casserole

* **Use Day-Old Bread:** Day-old bread is slightly drier and will absorb the custard better without becoming soggy. If you only have fresh bread, you can dry it out slightly by leaving it out on the counter for a few hours or toasting it lightly in the oven.
* **Don’t Skip the Overnight Soak:** The overnight soak is crucial for allowing the bread to fully absorb the custard. This results in a soft and decadent texture that is the hallmark of a great French toast casserole.
* **Adjust the Sweetness to Your Liking:** The amount of sugar in the recipe can be adjusted to your liking. If you prefer a sweeter casserole, you can add more sugar. If you prefer a less sweet casserole, you can reduce the amount of sugar or use a sugar substitute.
* **Use Your Favorite Fruit:** While this recipe calls for blueberries, you can easily substitute with other fruits such as raspberries, strawberries, peaches, or apples. You can also use a combination of different fruits.
* **Add a Streusel Topping:** For an extra layer of flavor and texture, consider adding a streusel topping to the casserole before baking. A simple streusel topping can be made with flour, butter, sugar, and spices.
* **Prevent Soggy Bottom:** To prevent the bottom of the casserole from becoming soggy, make sure to use a well-greased baking dish and don’t over-soak the bread. Gently press the bread down into the custard to ensure that it is evenly coated, but avoid pressing too hard.
* **Make it Gluten-Free:** To make this recipe gluten-free, simply use gluten-free bread and ensure that all other ingredients are also gluten-free.

## Variations and Customizations

This recipe is a great starting point for creating your own unique French toast casserole. Here are a few ideas to get you started:

* **Cinnamon Roll French Toast Casserole:** Add a can of refrigerated cinnamon roll dough to the casserole along with the bread cubes. Bake as directed.
* **Apple Cinnamon French Toast Casserole:** Add diced apples and a sprinkle of cinnamon to the casserole along with the bread cubes and blueberries.
* **Chocolate Chip French Toast Casserole:** Add chocolate chips to the casserole along with the bread cubes and blueberries.
* **Pecan Pie French Toast Casserole:** Add chopped pecans and a drizzle of maple syrup to the casserole along with the bread cubes and blueberries.
* **Savory French Toast Casserole:** Omit the sugar and vanilla extract from the custard and add savory ingredients such as sausage, cheese, and vegetables.
