Why You'll Love This Recipe
This casserole feels fancy but is surprisingly simple. I've found it’s a crowd-pleaser that feels special, yet you don’t have to be a pro baker to pull it off. Plus, it’s great for making ahead so you can savor that leisurely morning!
- Make-Ahead Magic: Prep it the night before and just pop it in the oven the next morning — perfect for easy hosting or busy weekends.
- Fresh Blueberry Burst: The fresh or frozen blueberries add a juicy tang that pairs beautifully with the custard-soaked brioche.
- Custardy and Comforting: The egg and milk custard infuses every bite, giving you that melt-in-your-mouth french toast feel.
- Simple Ingredients: You probably have everything on hand already, so it’s an easy morning win without any last-minute runs to the store.
Ingredients & Why They Work
Each ingredient plays a key role in balancing flavors and textures. Brioche bread is soft and rich, soaking up the custard beautifully, while the blueberries bring a fresh zing. Choose good-quality vanilla and real butter, and you’ll taste the difference!
- Brioche bread: Its buttery, tender crumb soaks up the custard luxuriously without getting soggy.
- Blueberries: Fresh or frozen adds juicy pops of flavor and a natural sweetness that brightens the dish.
- Lemon zest: A subtle twist of citrus cuts through the richness and elevates the flavors.
- Light brown sugar: Adds a gentle caramel note and helps sweeten the casserole evenly.
- Eggs: The backbone of the custard, binding everything together for that creamy texture.
- Whole milk: Keeps the custard rich and smooth without overpowering it.
- Unsalted butter: Melted and cooled for a silky custard and added flavor depth.
- Pure vanilla extract: Brings warmth and sweet aromatic notes that tie all the flavors together.
- Pinch of salt: Enhances sweetness and balances the overall taste.
Make It Your Way
I love tweaking this casserole depending on the season or who I’m cooking for. Maybe you want it dairy-free or want to sneak in some extra berries — don’t be shy to experiment. It’s quite forgiving and always delicious.
- Variation: Once, I swapped out blueberries for fresh strawberries and a sprinkle of cinnamon—it was a hit with my kids who liked the sweeter twist.
- Dairy-Free Option: Use almond or oat milk and coconut oil instead of butter. The texture changes a bit, but the fruity custard base still shines.
- Extra Crunch: Add a streusel topping of brown sugar and chopped nuts before baking for a delightful texture contrast.
Step-by-Step: How I Make Blueberry French Toast Casserole Easy Breakfast Bake Recipe
Step 1: Prep Your Bread and Berries
First, slice your brioche into 1-inch cubes using a serrated knife—that helps keep pieces uniform so everything bakes evenly. Go for thick cubes because thinner ones can get mushy. Lay half in your greased baking dish, then sprinkle half the blueberries over them. Repeat with the remaining bread and berries, spreading evenly.
Step 2: Mix the Lemon Sugar
In a large bowl, toss together the lemon zest and light brown sugar with your fingertips. This little step releases the oils from the lemon peel, filling your kitchen with a fresh, inviting scent and adding complexity to the sweetness.
Step 3: Whisk the Custard
Whisk eggs, milk, melted butter, vanilla, salt, and your lemon-infused sugar until smooth. This eggy custard will soak into the bread cubes, so make sure it’s well combined. Pour it slowly and evenly over the layers in your pan.
Step 4: Chill for Flavors to Meld
Cover the dish tightly with foil and pop it in the fridge for at least 4 hours, ideally overnight. This is when the magic happens—bread absorbs the custard, and flavors deepen. Patience is key here for the perfect custardy texture.
Step 5: Bake to Golden Perfection
Preheat your oven to 350°F. Let your casserole sit at room temp while the oven heats up—that prevents a cold shock that can affect baking times. Bake covered for 45 minutes, then remove the foil to let the top brown and puff up for 10–15 minutes. You’re aiming for a golden crust and a firm, custardy center, so stick a knife in to check it’s set.
Top Tip
After making this Blueberry French Toast Casserole Easy Breakfast Bake Recipe a bunch of times, I’ve nailed down a few tricks to get it just right every time. These small details really elevate your breakfast game.
- Use Day-Old Brioche: I swear by bread that’s a little stale rather than fresh — it soaks up the custard better without falling apart.
- Don’t Thaw Frozen Blueberries: Toss the berries in frozen — this keeps them from bleeding too much and turning the casserole soggy.
- Lemon Zest Into Sugar: Rubbing zest in the sugar releases oils that add a fresh, zingy aroma boosting the blueberry flavor beautifully.
- Cover While Baking: Keep the casserole covered initially so the custard cooks through without drying out, then uncover at the end for a golden crust.
How to Serve Blueberry French Toast Casserole Easy Breakfast Bake Recipe
Garnishes
I usually dust the warm casserole with powdered sugar and drizzle pure maple syrup on top — nothing beats that sweet finish. Sometimes I add a dollop of whipped cream or a sprinkle of toasted sliced almonds for extra texture and richness.
Side Dishes
I love pairing it with crispy bacon or breakfast sausage for savory balance. A fresh fruit salad or a light green smoothie also complements the richness nicely.
Creative Ways to Present
For special occasions, I serve it in miniature ramekins for individual portions — it feels extra fancy and helps with portion control. A sprinkle of fresh mint leaves or edible flowers on top can also brighten the table visually.
Make Ahead and Storage
Storing Leftovers
I cover any leftovers tightly with plastic wrap and store them in the fridge for up to 3 days. The flavors deepen overnight, making leftover bites just as delightful.
Freezing
I’ve frozen this casserole successfully by baking first, then letting it cool completely before wrapping it tightly with foil and plastic wrap. When ready to eat, thaw overnight in the fridge and reheat covered in the oven.
Reheating
To reheat, I cover the casserole with foil to keep moisture in and warm it at 325°F until heated through—usually about 15-20 minutes. This keeps the custard creamy without drying out the top.
Frequently Asked Questions:

Make sure to use bread that’s at least a day old so it can soak custard without falling apart. Also, don’t thaw frozen blueberries before layering — keeping them frozen prevents excess moisture. Finally, refrigerating the casserole overnight allows even soaking which helps texture.

Description
Blueberry French Toast Casserole is a delightful breakfast dish featuring layers of brioche bread and fresh blueberries soaked in a rich custard with lemon zest, brown sugar, and vanilla. Prepared the night before and baked in the morning, it offers a perfect combination of sweet, tangy, and custardy flavors that serve a crowd with ease.
Ingredients
Main Ingredients
- 16 ounces brioche bread
- 2 cups fresh or frozen blueberries (if frozen, do not thaw)
- 1 tablespoon lemon zest
- ⅔ cup lightly packed light brown sugar
- 8 large eggs
- 1 cup whole milk
- 4 tablespoons unsalted butter (melted and cooled)
- 1 tablespoon pure vanilla extract
- Pinch of salt
Instructions
- Prepare the Baking Dish: Spray a 9x13-inch baking pan with nonstick cooking spray to prevent sticking.
- Assemble Bread and Blueberries: Using a large serrated knife, slice the brioche bread into 1-inch cubes. Spread half of the bread cubes evenly in the bottom of the prepared baking pan. Sprinkle half of the blueberries over the bread. Layer the remaining bread cubes on top and finish with the rest of the blueberries, distributing evenly.
- Make Lemon Brown Sugar Mixture: In a large bowl, add the lemon zest and brown sugar. Rub the lemon zest into the sugar with your fingertips until well combined and fragrant to infuse citrus flavor.
- Whisk Custard Mixture: Add the eggs, whole milk, melted and cooled butter, vanilla extract, and a pinch of salt to the lemon brown sugar mixture. Whisk thoroughly until completely combined and smooth.
- Soak Bread Mixture: Slowly pour the custard mixture evenly over the layered bread and blueberries in the baking dish. Cover the pan tightly with foil and refrigerate for at least 4 hours or overnight, up to 12 hours, to allow the bread to absorb the custard.
- Preheat Oven and Prepare to Bake: When ready to bake, preheat the oven to 350°F. Remove the casserole from the refrigerator and let it sit at room temperature while the oven preheats to ensure even baking.
- Bake Covered: Place the covered baking dish in the preheated oven and bake for 45 minutes to cook the custard and soften the bread thoroughly.
- Bake Uncovered: Remove the foil and continue baking uncovered for an additional 15 minutes or until the french toast casserole is puffed evenly and the center custard is fully set.
- Serve: Remove from oven and serve warm, optionally topped with maple syrup or a dusting of powdered sugar for extra sweetness.
Notes
- Use fresh, plump blueberries for the best flavor, but frozen blueberries work well if not thawed before using.
- Prepare the casserole the night before and refrigerate to save time on the day you want to serve it.
- Letting the casserole sit at room temperature before baking promotes even cooking and fluffiness.
- Serve with maple syrup or powdered sugar to enhance sweetness and presentation.
- Use brioche bread for a rich, buttery texture; other sturdy bread types like challah can be substituted if needed.
