Ingredients You’ll Need
With a just-right mix of everyday essentials and fresh flavors, these ingredients are the building blocks of something truly special. Each plays a key role, from the eggs for a silky custard to the blueberries for a tart pop of color and taste.
- French bread: Using slightly stale bread helps soak up the custard without losing structure, creating the perfect bite.
- Blueberries (fresh or frozen): These little berries add bursts of sweetness and vibrant color throughout the casserole.
- Eggs: The foundation of your creamy custard base, binding everything together beautifully.
- Milk: Contributes to the richness of the custard while keeping it light and pillowy.
- Heavy cream: Adds extra decadence and creaminess—don’t skip if you want maximum wow factor!
- Maple syrup or brown sugar: Sweetens the casserole and adds a lovely depth of flavor.
- Vanilla extract: Enhances the overall aroma and flavor, making every bite feel extra special.
- Ground cinnamon: Warms up the flavor profile and pairs perfectly with blueberries.
- Salt: Just a pinch brings all the flavors into perfect balance.
- Unsalted butter (melted): Adds a luxe finish to the custard, upping the flavor in every layer.
- All-purpose flour (for topping): Creates a crumbly, irresistible streusel layer.
- Brown sugar (for topping): Offers caramel-like sweetness and helps the topping brown beautifully.
- Cinnamon (for topping): Extra spice in the streusel for another layer of warm flavor.
- Unsalted butter (cold and cubed, for topping): Makes the topping crumbly and deliciously golden as it bakes.
How to Make Blueberry French Toast Casserole Delight
Step 1: Prepare Your Baking Dish and Bread
Start by greasing a 9×13-inch baking dish with either butter or a nonstick spray—this keeps things from sticking and makes cleanup a breeze. Cut your day-old French bread into hearty 1-inch cubes for the best texture. Layer half of the bread in your dish, sprinkle over half the blueberries, and then repeat to build up gorgeous berry-studded layers.
Step 2: Whisk the Custard
In a big mixing bowl, whisk together the eggs, milk, heavy cream, maple syrup or brown sugar, vanilla, cinnamon, and salt. Whisking well ensures a smooth, evenly flavored custard. Once combined, pour this mixture slowly and evenly over all the bread and berries—take a moment to press down gently with your hands or a spatula so that every cube of bread gets well coated.
Step 3: Let It Soak
This step is the secret to your Blueberry French Toast Casserole Delight’s dreamy texture! Cover the baking dish with plastic wrap and pop it in the fridge for at least 2 hours, or overnight if you love easy mornings. The bread will absorb the custard, ensuring every bite is moist but never soggy.
Step 4: Mix and Add the Topping
Right before baking, it’s time to work a little magic with the streusel topping. In a small bowl, combine flour, brown sugar, and cinnamon, then cut in the cold, cubed butter using a pastry cutter or even your fingers if that’s your style. You want a crumbly mixture—not too fine. Sprinkle it generously over the soaked casserole for irresistible crunch and flavor.
Step 5: Bake to Golden Perfection
Preheat your oven to 350°F. Bake the casserole uncovered for 45 to 55 minutes, until the top is beautifully golden brown and the center is set. If you crave an extra-crisp top, switch to broil for the last minute or two—just don’t take your eyes off it! Allow it to cool slightly so the custard sets, then prepare to wow everyone at brunch.
How to Serve Blueberry French Toast Casserole Delight

Garnishes
The finishing touches truly elevate your Blueberry French Toast Casserole Delight. Try a dusting of powdered sugar for classic charm, a dollop of whipped cream for extra decadence, or a generous drizzle of maple syrup to echo the casserole’s sweet notes. Fresh extra blueberries scattered on top add color and tartness.
Side Dishes
Balance out this sweet, rich bake with a side of crispy bacon or breakfast sausage for a savory counterpoint. For a lighter pairing, serve with a bowl of Greek yogurt and fresh fruit alongside. A hot carafe of coffee or a pitcher of freshly squeezed orange juice completes the brunch dream.
Creative Ways to Present
If you want to make Blueberry French Toast Casserole Delight the star of your table, bake it in individual ramekins for personal servings or bring the whole bubbling dish straight to the table for everyone to scoop out their own. Serving it in squares with a sprig of mint or edible flowers gives a restaurant-worthy touch, especially for special occasions or holiday brunches.
Make Ahead and Storage
Storing Leftovers
Leftover casserole can be a blessing! Simply cover your dish tightly with foil or plastic wrap, or transfer individual portions to airtight containers. Store in the refrigerator for up to 3 days—perfect for busy mornings or afternoon treats.
Freezing
You can freeze Blueberry French Toast Casserole Delight either baked or unbaked. If freezing unbaked, assemble (without the topping) and wrap well for up to 2 months. Thaw in the fridge overnight before baking as directed. For baked leftovers, let cool completely, then freeze tightly wrapped portions. Just thaw and reheat as needed!
Reheating
To recapture that just-baked magic, reheat individual slices in the microwave for quick breakfasts, or warm larger portions in a 350°F oven, covered with foil, until heated through. For the crispiest top, pop it under the broiler for a minute or two before serving.
FAQs
Can I use other types of bread instead of French bread?
Absolutely! Brioche or challah make lovely, rich substitutes, though day-old French bread gives a great texture. Just be sure whatever you use is sturdy enough to hold up during soaking.
Do I have to use fresh blueberries?
No worries if you only have frozen blueberries; they work beautifully in Blueberry French Toast Casserole Delight. Just toss them in straight from the freezer—no need to thaw first!
Can I make it dairy-free?
Yes, you can experiment with dairy-free alternatives such as almond milk, coconut cream, and a plant-based butter. The result will be slightly different but still delicious.
How do I know when the casserole is fully baked?
You’ll know your Blueberry French Toast Casserole Delight is ready when the center feels set (not jiggly) and the topping is golden brown. Insert a knife in the center; it should come out mostly clean.
Can I add nuts or other fruits?
Absolutely! Toss in raspberries, blackberries, or even chopped pecans or walnuts for some crunch and extra flavor—a great way to customize the recipe for your family’s favorites.
