How to Make Overnight Blueberry French Toast Casserole Recipe
Step 1: Prepare the Bread
Start by slicing your French bread diagonally into about 10 to 14 slices, each around half to three-quarters of an inch thick. This shape maximizes surface area for soaking and baking evenly. Lay the slices in a single layer inside a 9×13 inch casserole dish. This ensures every piece absorbs the custard overnight perfectly.
Step 2: Make and Pour the Custard
In a medium bowl, whisk together eggs, milk, baking powder, and vanilla until combined. Pour this mixture slowly and evenly over the arranged bread slices. Be sure to flip the slices gently so each side absorbs the custard well. This soaking step is the secret to a tender, souffle-like texture. Cover your dish tightly and chill it overnight or for at least a couple of hours if you’re in a hurry.
Step 3: Preheat and Prepare to Bake
When your baking day arrives, preheat your oven to 425 degrees Fahrenheit. Grease another 9×13 inch pan to prevent sticking and prepare for the blueberry layer. This ensures everything bakes up beautifully without any hiccups.
Step 4: Create the Blueberry Layer
Combine the fresh blueberries, sugar, cornstarch, and cinnamon in the greased pan. Stir gently until all ingredients are evenly mixed, which will create that luscious, thickened berry bed under the bread. Spread this mixture out evenly so every bite has a sweet and tangy surprise.
Step 5: Assemble the Casserole
Flip your custard-soaked bread slices so the wettest side faces down and layer them, single file, on top of the blueberry mixture. This layering traps the juicy berries beneath the tender bread. Brush melted butter over the bread slices generously to encourage that breathtakingly golden crust as it bakes.
Step 6: Bake to Perfection
Bake the casserole at 425 degrees for 24 to 26 minutes, until the surface is beautifully golden and the berries are bubbling enticingly underneath. This high-heat bake caramelizes the edges while keeping the interior moist and custardy.
Step 7: Finish and Serve
Once out of the oven, sprinkle powdered sugar lightly over the top for an inviting, sweet dusting. Serve it immediately to enjoy the contrast of warm bread and vibrant berries in every bite.

Garnishes

Side Dishes
This casserole shines on its own, but pairing it with some crispy bacon or sausage adds a savory contrast that complements the sweet, fruity notes. Fresh fruit salad or a citrusy smoothie on the side can balance the richness beautifully for a well-rounded brunch spread.
Creative Ways to Present
For a fun twist, serve this casserole in individual ramekins for perfectly portioned, elegant servings.

Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors will develop even more, making each reheated bite just as delightful as the first.
Freezing
This casserole freezes well, perfect for busy mornings. Freeze in portions wrapped tightly in plastic wrap and aluminum foil or freezer containers for up to 2 months. Thaw overnight in the fridge before reheating for the best texture retention.
Reheating
Reheat leftovers in a 350-degree oven for 15-20 minutes until warmed through and the top is crisp again. Avoid microwaving to keep the bread from becoming soggy, ensuring you get that freshly-baked feel every time you enjoy it.
FAQs
Can I use other types of bread?
Yes! While French bread works best due to its structure, you can substitute with brioche, challah, or even thick-cut sandwich bread for different textures and flavors.
Do I have to soak the bread overnight?
Overnight soaking gives the best custard-soaked texture, but if you’re short on time, a couple of hours will still yield delicious results.
Can I use frozen blueberries?
Absolutely. Just thaw and drain them well to avoid excess liquid that can make the casserole soggy.
Is this recipe suitable for dairy-free diets?
With substitutions like almond milk and a non-dairy butter alternative, you can adapt this recipe while keeping the amazing flavor intact.
Can I make this recipe vegan?
Making a vegan version would require replacing eggs with a suitable binder like flax eggs and using plant-based milk and butter alternatives, which might change the texture but can still be tasty.
