How to Make Blueberry French Toast Casserole Recipe

Step 1: Prepare the Baking Dish and Bread

Start by preheating your oven to 350°F (175°C). Greasing your 9×13-inch baking dish with butter or cooking spray ensures the casserole won’t stick and helps achieve a nice crust. Next, spread those lovely cubes of French bread evenly across the dish—this is going to be the cozy bed for our blueberries!

Step 2: Add the Blueberries

Sprinkle the fresh blueberries over the bread cubes, making sure they are evenly distributed. This will create delightful pockets of fruity goodness baked right into every bite.

Step 3: Whisk Together the Custard

In a large bowl, whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, cinnamon, nutmeg, and salt. This fragrant, velvety custard is the magic that transforms humble bread into a soft, rich breakfast casserole.

Step 4: Soak the Bread

Pour the custard mixture gently over the bread and blueberries, making sure every cube is soaked. Press the bread down lightly to help it absorb all those luscious flavors. This soaking step is what makes the dish melt-in-your-mouth irresistible!

Step 5: Refrigerate to Set

Cover the dish tightly with plastic wrap and pop it in the fridge for at least 2 hours—or even better, overnight. This resting time allows the bread to soak up all the custard completely, so every bite is perfectly tender and flavorful.

Step 6: Ready to Bake

When you’re ready to bake, remove the casserole from the fridge and let it warm up at room temperature for about 10-15 minutes. This helps the casserole cook evenly, giving you a beautiful golden top without a soggy center.

Step 7: Add Butter and Bake

Drizzle the melted butter all over the top—it adds richness and ensures a crisp, golden crust forms during baking. Bake for 45 to 50 minutes until the casserole is set in the middle and the top is a gorgeous, inviting golden brown.

Step 8: Cool Slightly and Serve

Allow the casserole to cool a bit before serving so it slices nicely. If you like, dust it with powdered sugar for a pretty finish and offer extra maple syrup on the table for drizzling.

Garnishes

A light dusting of powdered sugar adds a touch of elegance, while fresh blueberries on top echo that burst of fruity freshness. For an extra indulgence, add a dollop of whipped cream or a scoop of vanilla ice cream to make breakfast feel like dessert.

Side Dishes

Complement your casserole with sides that balance its sweetness. Crisp bacon or savory breakfast sausage offers salty contrast, while a fresh fruit salad adds brightness and variety to the meal. A cup of hot coffee or freshly brewed tea rounds out the morning perfectly.

Creative Ways to Present

For a brunch gathering, serve the casserole family-style in the baking dish with colorful plates and utensils nearby. Alternatively, cut individual squares and layer them on pretty serving platters topped with more fresh berries and a drizzle of syrup. You could even use mini ramekins for single servings, perfect for an elegant touch or a special occasion.

Make Ahead and Storage

Storing Leftovers

If you have leftovers from your Blueberry French Toast Casserole Recipe, no worries! Store them covered in the refrigerator, and they should keep fresh for up to three days. The flavors often taste even better the next day after sitting together.

Freezing

You can freeze portions of the baked casserole wrapped tightly in foil or in airtight containers. Frozen pieces will maintain quality for about one to two months. When you want a quick breakfast, just thaw overnight in the fridge before reheating.

Reheating

To enjoy your leftovers warm, reheat individual servings in the microwave for about 60 to 90 seconds or until heated through. For a crispier texture on top, pop the portions in a preheated oven at 350°F for 10 to 15 minutes.
