Save There's something about a breakfast casserole that makes a quiet morning feel like a celebration. My neighbor brought this to our place after my daughter was born, and I remember thinking how it managed to taste like cinnamon rolls and banana bread had a perfectly delicious love story on a plate. The cream cheese swirls hidden inside were like little flavor surprises, and the brioche soaked up all that eggy custard without falling apart. That morning, between feedings and exhaustion, this dish tasted like someone genuinely cared. Now whenever I make it, that feeling comes right back.
I made this for my book club's monthly breakfast gathering, and watching everyone's faces light up when they bit into it was pure joy. One friend asked if I'd bought it from a bakery, which felt like the highest compliment. The warm spices filled the kitchen while it baked, and people kept wandering back to the dining room just to sniff the air. That's when I realized this dish does something beyond feeding people—it creates an atmosphere.
Ingredients
- Brioche or challah bread, cut into 1-inch cubes (about 500 g): This is your structure, and the key is using bread that's sturdy enough to soak up the custard without turning to mush. Day-old bread works beautifully because it's slightly dried out and holds up better than fresh.
- Mashed ripe bananas (2 medium): They add natural sweetness and moisture, plus that subtle warmth that makes people say they taste something familiar without quite knowing what it is.
- Eggs (6 large) and egg yolk (1): These bind everything together and create that custardy texture that makes it feel luxurious when you bite into it.
- Whole milk and heavy cream (1 1/2 cups and 1/2 cup): The milk hydrates the bread while the cream adds richness that elevates this from ordinary to memorable.
- Light brown sugar and granulated sugar (1/2 cup and 1/4 cup): Brown sugar brings depth and molasses notes, while granulated sugar keeps things balanced and lets the spices shine.
- Vanilla extract (2 tsp plus 1 tsp): Use pure vanilla if you can; it makes a noticeable difference in the final flavor.
- Ground cinnamon (2 tbsp total): This is what makes it smell like someone's been baking all morning, even if you just threw it together last night.
- Ground nutmeg and fine sea salt (1/4 tsp each): Nutmeg adds a whisper of warmth that ties everything together, while salt makes all the flavors pop without tasting salty.
- Softened cream cheese (8 oz) with sugar and vanilla: This creates those creamy pockets of brightness that contrast beautifully with the cinnamon-spiced bread.
- Melted butter with brown sugar and cinnamon topping (2 tbsp butter, 1/3 cup brown sugar, 1 tbsp cinnamon): This caramelizes slightly as it bakes and creates a golden, slightly crispy top layer.
Instructions
- Prepare your baking dish and bread:
- Grease a 9x13-inch dish generously, then arrange half your cubed bread evenly across the bottom. This first layer is your foundation, so don't skimp on coverage.
- Build the custard base:
- In a large bowl, whisk together mashed bananas, eggs, milk, cream, brown sugar, granulated sugar, vanilla, cinnamon, nutmeg, and salt until everything is smooth and well combined. You'll notice how the banana almost dissolves into the mixture, creating that subtle flavor.
- Layer and soak the first half:
- Pour half your custard over the bread cubes and press gently so the bread starts absorbing all that eggy goodness. Don't be aggressive about it—gentle pressing ensures even soaking without breaking up the bread.
- Create the cream cheese swirl:
- Beat softened cream cheese with sugar, egg yolk, and vanilla until it's smooth and creamy. This mixture should be thick enough to hold its shape when you spoon it, not runny. Dollop it by spoonfuls across the soaked bread, leaving little pockets of it scattered throughout.
- Build the final layers:
- Add your remaining bread cubes on top, then pour the rest of the custard over everything. Press gently again to make sure all the bread gets moistened, especially around the edges where it tends to dry out during baking.
- Add the cinnamon sugar topping:
- Mix melted butter with brown sugar and cinnamon, then drizzle or dot it across the top. This will caramelize and create that beautiful golden crust.
- Chill overnight:
- Cover tightly with plastic wrap or foil and refrigerate for at least 6 hours, though 8 is ideal. This waiting period is actually when the magic happens—the bread fully absorbs the custard and flavors meld together.
- Bake to golden perfection:
- Preheat your oven to 350°F while the casserole comes out of the fridge. Bake uncovered for 40-45 minutes until it's puffed and golden and a knife inserted in the center comes out clean. The top will look slightly jiggly when it comes out, but it will set as it cools.
- Rest before serving:
- Let it cool for 10-15 minutes before cutting and serving. This helps the custard set completely so you get clean slices instead of a sloppy casserole.
Save My mother-in-law has started requesting this for every holiday breakfast, and last year she asked for the recipe to make it at her house. Watching her text me photos of her attempt, complete with commentary about how the kitchen smelled, made me realize this dish has this beautiful way of getting passed along and made your own. It's become this little thread of connection across our family.
Why This Casserole Works
The genius of this dish is how it layers flavors without complicating things. You've got the warm spice notes of cinnamon and nutmeg running through the custard base, which plays beautifully against the tart brightness of the cream cheese. The banana adds moisture and a subtle sweetness that ties it all together, while the brioche's buttery richness keeps everything feeling luxurious. Every element serves a purpose, and nothing fights for attention—it all just works together.
Making It Ahead and Customizing
This is genuinely one of those recipes where making it ahead makes everything better, not just easier. The overnight refrigeration is actually part of the recipe's success, allowing flavors to deepen and the bread to fully hydrate. If you want to push it further, you can freeze the assembled unbaked casserole for up to a month—just wrap it well, thaw it overnight in the fridge, and bake as directed.
For variations, chopped pecans or walnuts sprinkled on top before baking add a wonderful crunch, though I find the cream cheese swirl is richness enough on its own. Some people brush the top with a little extra egg wash before baking for an extra-glossy finish, which I've done and absolutely recommend if you have an egg on hand.
Serving and Pairing Ideas
The beauty of this casserole is that it needs very little accompaniment—maybe a dusting of powdered sugar if you're feeling fancy, or a drizzle of maple syrup on individual servings for those who want extra sweetness. Strong coffee is the classic pairing because its bitterness cuts through the richness perfectly. I've also served it with chai tea, which echoes the spices in the dish and feels surprisingly complete.
- Offer a small bowl of powdered sugar on the side so guests can dust their portion to their liking.
- Cold butter and a good jam work beautifully alongside if you want additional flavors without competing.
- This reheats beautifully, so don't hesitate to make it the day before a gathering and simply warm it gently in a low oven before serving.
Save This casserole has become my answer to 'I want to impress people without spending all morning in the kitchen.' It sits in the fridge overnight doing the work for you, then bakes into something that tastes like you've been in the kitchen for hours. That's the kind of recipe worth keeping close.
Recipe FAQ
- → Can I use different bread instead of brioche or challah?
While brioche and challah provide the richest, most tender texture, you can substitute French bread, sourdough, or even thick-cut Texas toast. Day-old bread works best as it absorbs the custard without becoming mushy.
- → What's the minimum chilling time before baking?
Plan for at least 6 hours of refrigeration, though 8 hours overnight allows the bread to fully absorb the custard and develop the best texture. The longer chill ensures even baking and prevents soggy centers.
- → Can I assemble and freeze this for later?
Yes, assemble the complete casserole, wrap tightly in plastic and foil, and freeze for up to one month. Thaw overnight in the refrigerator before baking as directed. Do not bake from frozen.
- → How do I know when it's fully baked?
The casserole is done when the top is golden brown and puffed, a knife inserted in the center comes out clean without wet custard clinging to it, and the internal temperature reaches 160°F. Allow 10-15 minutes to set before serving.
- → Can I reduce the sugar for a lighter version?
You can decrease both brown and granulated sugars by 25% without significantly affecting texture. The bananas provide natural sweetness, and the cinnamon flavor remains prominent. For further reduction, consider using a natural sweetener like maple syrup in the custard.
- → What toppings pair well with this bake?
Warm maple syrup, powdered sugar dusting, or a drizzle of vanilla glaze complement the flavors beautifully. Fresh berries, sliced bananas, or toasted pecans add nice contrast. A dollop of Greek yogurt offers tangy balance.
