Ingredients
- 1 loaf of challah or brioche bread, cubed
Challah or brioche adds richness and a slight sweetness to the casserole. The soft texture allows it to soak up the egg mixture, resulting in a custardy interior that pairs beautifully with the blueberries. - 2 cups fresh blueberries
Fresh blueberries not only provide a burst of juicy flavor but also bring antioxidants and fiber to the dish. They break down slightly during baking, creating a lovely, fruity sauce that mingles with the custard. - 6 large eggs
Eggs are essential for binding the ingredients together and creating a cohesive custard. They also add protein, making the casserole more filling and satisfying. - 2 cups milk
Milk helps to create the custard-like texture that is key to the dish. Using whole milk will yield a creamier casserole, while skim milk can be used for a lighter option. - 1/2 cup granulated sugar
Sugar sweetens the custard and balances the tartness of the blueberries. Adjust the amount based on your preference for sweetness. - 1 tsp vanilla extract
Vanilla adds depth and warmth to the flavors in the casserole. It complements the sweetness of the bread and blueberries, making each bite more enjoyable. - 1/2 tsp salt
Salt enhances the overall flavor and helps to balance the sweetness. Even a small amount can make a significant difference in how the flavors come together. - 1 tsp ground cinnamon
Cinnamon provides warmth and a hint of spice that pairs wonderfully with the blueberries. It adds an aromatic quality that makes the dish even more inviting. - Butter for greasing the baking dish
Butter prevents sticking and adds a touch of flavor to the casserole. A well-greased dish is crucial for easy serving. - Powdered sugar for serving (optional)
While optional, powdered sugar adds a nice finishing touch that makes the dish look even more enticing. A light dusting enhances the presentation and sweetness.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C).
Preheating the oven ensures your casserole cooks evenly and thoroughly. If the oven is not hot when you place the dish inside, it may not rise correctly or could take too long to bake.
Step 2: Grease a 9×13 inch baking dish with butter.
Greasing the dish properly is important to prevent sticking and to ensure easy removal of servings later. Use a generous amount of butter to coat the bottom and sides, creating a non-stick surface.
Step 3: In a large bowl, whisk together the eggs, milk, sugar, vanilla, cinnamon, and salt until fully combined.
This step creates the custard base for your casserole. Whisk until you see no lumps; this ensures that the eggs and liquids are fully incorporated, providing a smooth texture throughout the dish.
Step 4: Add the cubed bread to the egg mixture, stirring gently to coat the bread evenly.
Gently folding the bread into the custard is crucial. You want each piece to soak up the mixture but avoid breaking the bread apart too much, maintaining some integrity for texture.
Step 5: Fold in the fresh blueberries, distributing them evenly throughout the mixture.
Incorporating the blueberries at this stage ensures they are evenly distributed, giving every bite a burst of fruity flavor. Be careful not to crush them, as you want them to maintain their shape.
Step 6: Pour the mixture into the prepared baking dish, spreading it out evenly with a spatula.
Pouring the mixture carefully into the dish helps to maintain an even layer, which ensures consistent cooking. Make sure to fill the dish without overflowing.
Step 7: Bake in the preheated oven for 35–45 minutes, or until the top is golden and the custard has set.
Baking at the right temperature and duration is vital. Keep an eye on the casserole as it bakes; the top should be lightly golden, and a toothpick inserted in the center should come out clean.
Step 8: Once baked, remove from the oven and allow to cool for a few minutes before serving.
Allowing the casserole to cool slightly helps it firm up, making it easier to slice and serve. Serve warm with a sprinkle of powdered sugar or maple syrup.

Choosing the Right Bread for Casserole Success
The choice of bread can greatly influence the texture and flavor of your Blueberry French Toast Casserole. While challah and brioche are traditional options for their indulgent richness, you can experiment with other types, such as whole-grain or even a stale baguette, which will absorb the custard beautifully. Whichever bread you choose, aim for one that has a slightly firm texture; it holds up better during the soaking and baking process.
The Benefits of Overnight Refrigeration
For those who prefer a streamlined morning routine, consider prepping your Blueberry French Toast Casserole the night before. After assembling the dish, cover it tightly with plastic wrap and refrigerate. This not only allows the flavors to meld overnight, enhancing the taste, but also ensures the bread is thoroughly soaked in the custard mixture. In the morning, you can simply pop it in the oven for a hassle-free breakfast.
Garnishing and Serving Suggestions
Presenting your Blueberry French Toast Casserole can elevate the dining experience. A light dusting of powdered sugar adds an elegant touch, while fresh blueberries or a drizzle of maple syrup can enhance flavor. Consider serving it alongside a dollop of Greek yogurt or vanilla ice cream for a delightful contrast. These garnishes not only improve presentation but also add complementary flavors and textures, making your meal truly memorable.
FAQs
What can I use instead of blueberries?
You can substitute blueberries with raspberries, chopped strawberries, or even diced peaches. Just ensure the fruit is not overly watery to maintain the casserole's consistency.
Why is my casserole too dry?
If your casserole comes out dry, you might not have soaked the bread long enough in the custard or used bread that was too stale. Ensure each piece is fully saturated before baking.
What if I want to make a smaller portion?
To make a smaller casserole, consider halving the ingredients and using a smaller baking dish, such as an 8×8 inch dish. Adjust the baking time to ensure it sets perfectly.
How do I know when the casserole is properly baked?
A properly baked casserole should have a golden top and when a toothpick or knife inserted into the center comes out clean, the custard should be set but not dry.
Can I add spices other than cinnamon?
Certainly! Nutmeg or cardamom can be wonderful alternatives to cinnamon, adding unique flavors that complement the sweetness of the blueberries.
What toppings work well with this casserole?
In addition to powdered sugar and maple syrup, consider garnishing with whipped cream, or serve alongside a fruit compote for extra flavor.
