• 1 teaspoon ground cinnamon

Ingredient Notes and Variations

• Bread: The type of bread you use will greatly affect the texture of the casserole. Brioche and challah are perfect choices because of their rich, soft texture that absorbs the custard beautifully. If you prefer a slightly firmer texture, French bread or even whole grain bread will work too.
• Blueberries: Fresh blueberries are ideal for this casserole, but you can use frozen blueberries if fresh ones aren’t in season. Just be sure to thaw them and pat them dry to avoid excess moisture in the casserole.
• Milk and Cream: The combination of whole milk and heavy cream gives the casserole a rich, custardy texture. You can use a lighter milk, like 2% or almond milk, but it may not be as indulgent.
• Spices: While cinnamon is the primary spice in this recipe, feel free to experiment with a pinch of nutmeg or cardamom for a different flavor profile. If you’re looking for more spiced recipes, try our Gingerbread Pancakes for a holiday breakfast twist!

Kitchen Equipment You’ll Need

Before you begin, make sure you have the following kitchen equipment:

• 9×13-inch baking dish (or similar size)
• Mixing bowl
• Whisk
• Sharp knife (for cutting the bread)
• Measuring cups and spoons
• Rubber spatula (for stirring and folding)
• Plastic wrap (for overnight refrigeration)

Having a sturdy 9×13-inch baking dish ensures that the casserole bakes evenly. You’ll also need a whisk for combining the egg mixture and a knife for slicing the bread. For another delicious casserole, check out our Mac and Cheese Meatloaf Casserole.

Step-by-Step Preparation: How to Make Blueberry French Toast Casserole

This Blueberry French Toast Bake is incredibly easy to assemble, and you can do it all in just a few steps!

Step 1: Prepare the Bread

Start by slicing your bread into cubes. Depending on the size of the bread slices, cut them into 1-inch cubes. The cubes should be large enough to hold their shape when soaked but small enough to bake evenly.

Step 2: Make the Custard Mixture

In a large mixing bowl, whisk together the eggs, milk, heavy cream, maple syrup, cinnamon, vanilla extract, and a pinch of salt. Whisk until everything is well combined and smooth. This custard mixture is what will soak into the bread cubes to create that deliciously rich texture.

Step 3: Assemble the Casserole

Butter your 9×13-inch baking dish with the melted butter. Next, place the bread cubes into the baking dish, spreading them out evenly. Gently pour the custard mixture over the bread cubes, ensuring that all the pieces are coated. Use a rubber spatula to gently press the bread into the liquid, helping the cubes absorb the custard.

Add the blueberries over the top of the bread mixture, gently pressing them into the bread. If you’re using frozen blueberries, make sure they’re evenly spread out.

Step 4: Refrigerate Overnight

Cover the baking dish with plastic wrap and refrigerate it overnight (or for at least 4 hours). This allows the bread to fully absorb the custard and results in a moist, flavorful casserole.

Step 5: Make the Topping

Before baking the casserole, make the crumbly topping. In a small bowl, combine the brown sugar, cold butter, and flour. Use your fingers or a pastry cutter to mix the ingredients until they resemble coarse crumbs. Sprinkle this topping over the casserole.

Step 6: Bake the Casserole

Preheat your oven to 350°F (175°C). When ready to bake, remove the casserole from the fridge and let it sit at room temperature for about 10 minutes. Bake for 45-50 minutes, or until the casserole is golden brown on top and a knife inserted in the center comes out clean.

Step 7: Serve and Enjoy

Once baked, remove the casserole from the oven and let it cool for a few minutes. Dust with powdered sugar if desired, and serve with extra maple syrup for drizzling.

Pro Tips for the Best Blueberry French Toast Casserole

• Use Stale Bread: If you have stale bread lying around, use it for this casserole! Stale bread absorbs the custard much better than fresh bread, resulting in a richer texture.
• Prep the Night Before: The beauty of this casserole is that you can make it ahead of time. Preparing it overnight allows the bread to soak up all the custard, resulting in a soft, moist interior.
• Add Nuts for Extra Crunch: If you want to add some texture, sprinkle chopped pecans or walnuts on top of the casserole before baking.

Common Mistakes to Avoid

• Not Letting It Soak Long Enough: If you don’t let the bread soak in the custard mixture long enough, it may turn out dry. Let it sit in the fridge for at least 4 hours, preferably overnight.
• Baking at the Wrong Temperature: Make sure to bake the casserole at the right temperature (350°F). Baking at a higher temperature can cause the top to burn before the center cooks through.
• Using Fresh Bread: Fresh bread doesn’t soak up the custard as well as slightly stale bread, so it’s best to use bread that’s a little dry.

Serving Suggestions

This Blueberry French Toast Casserole is perfect for easy brunches or holiday breakfasts. Serve it alongside other breakfast favorites like crispy bacon, scrambled eggs, or fresh fruit salad. You can also top it with whipped cream or Greek yogurt for a bit of creaminess. For more breakfast recipes, try our Cinnamon Roll Casserole.

Creative Presentation Ideas

• Serve in Individual Portions: If you’re serving a crowd, consider portioning out the casserole into individual ramekins. Top each one with a dollop of whipped cream or a drizzle of syrup for a personal touch.
• Garnish with Fresh Mint or Berries: Fresh mint leaves or extra blueberries make a beautiful garnish on top of each serving.

Flavor Variations and Add-Ins

While this casserole is already packed with flavor, you can customize it to your liking:

• Add Nuts: Chopped nuts like pecans or almonds will add a nice crunch to the casserole.
• Use Different Fruits: Instead of blueberries, try using strawberries, raspberries, or blackberries for a different flavor profile.
• Cinnamon Swirl: Add a swirl of cinnamon sugar in between the layers of bread before pouring the custard mixture.

How to Store and Reheat

Store any leftover casserole in an airtight container in the fridge for up to 3 days. To reheat, simply microwave individual portions for 30 seconds to 1 minute or place the casserole in the oven at 350°F for 10-15 minutes until heated through.

Make-Ahead Tips

This Blueberry French Toast Bake is perfect for meal prep. Assemble the casserole the night before and refrigerate it until you’re ready to bake it in the morning. You can also freeze the casserole before baking. Just make sure to cover it tightly in plastic wrap and aluminum foil. To bake from frozen, increase the baking time by about 15 minutes.

Frequently Asked Questions

Can I use frozen blueberries?
Yes, frozen blueberries will work just fine. Just make sure to thaw and drain them before adding to the casserole to prevent excess moisture.

Can I make this without overnight refrigeration?
