Ingredients You’ll Need

This recipe keeps things simple, relying on a handful of kitchen staples that come together in perfect harmony to deliver layers of flavor and comforting texture. Each ingredient plays its part — from the richness of the cream and eggs to the sweet aromatic notes of banana and vanilla extracts, plus the irresistible flakiness of day-old croissants.

• 1 cup whole milk: Adds creaminess and helps create the custard base that soaks into the croissants.
• 1 cup heavy cream: Boosts the richness for a decadently smooth texture.
• 2 large eggs: Essential for thickening the custard and binding the casserole together.
• 1 cup granulated sugar: Sweetens the dish without overpowering the natural banana flavor.
• 1 tablespoon vanilla extract: Brings a warm, familiar aroma that deepens the overall taste.
• 1 tablespoon banana extract: Intensifies the banana flavor in every bite for that signature twist.
• 1/4 teaspoon salt: Balances the sweetness and enhances all the other flavors.
• 1 ripe but not overripe banana, sliced: Adds fresh fruitiness and a lovely texture contrast.
• 6 day-old croissants, cut or torn into 1-2 inch pieces: Their sturdy, flaky nature soaks up the custard beautifully without falling apart.
• Maple syrup, for serving: The perfect finishing touch to drizzle over warm servings for extra sweetness and depth.

How to Make Banana Croissant “French Toast” Casserole

Step 1: Prepare Your Baking Dish and Oven

Start by preheating your oven to 350°F (175°C) to ensure it’s hot and ready when your casserole is assembled. Spray an 8 x 8-inch baking dish generously with cooking spray so the custard won’t stick, and set it aside while you mix everything together.

Step 2: Whisk Together the Custard Mixture

In a large bowl, whisk the whole milk, heavy cream, eggs, granulated sugar, vanilla extract, banana extract, and salt. The key here is to blend everything smoothly so the custard is evenly sweet and infused with fragrant banana and vanilla notes that will soak into every croissant piece.

Step 3: Coat the Croissant Pieces

Add your torn or cut croissants into the custard mixture, stirring gently to coat every piece thoroughly. Let the croissants soak for 25 to 30 minutes, stirring about halfway through at 15 minutes to help ensure all the fluffy, buttery bits can soak up that rich custard magic.

Step 4: Assemble and Nestle Banana Slices

Transfer the soaked croissant and custard mixture into the prepared baking dish. Arrange the banana slices across the top, gently pressing them into the custard. This not only looks beautiful after baking but also creates pockets of fresh banana flavor throughout the casserole.

Step 5: Bake to Golden Perfection

Bake for 45 to 50 minutes, until the custard is set and you see the golden brown croissants starting to crisp around the edges. The smell that fills your kitchen at this point is pure comfort food heaven. Once out of the oven, let it rest for 10 minutes before serving so the flavors meld even more.

How to Serve Banana Croissant “French Toast” Casserole

Garnishes

For garnishes, a warm drizzle of maple syrup is the classic choice that adds a caramel sweetness to every bite. You can also sprinkle powdered sugar or chopped toasted walnuts over the top for a bit of crunch and visual appeal. Fresh banana slices on the side never hurt either, doubling down on that luscious banana factor.

Side Dishes

This casserole holds its own as a hearty centerpiece, but if you want to build a fuller brunch spread, consider serving it alongside fresh berries or a simple fruit salad to add brightness. Crispy bacon or breakfast sausage also pair beautifully if you like a savory contrast to the dish’s sweetness.

Creative Ways to Present

Transform your Banana Croissant “French Toast” Casserole into an eye-catching brunch dish by placing it in an attractive ceramic bakeware or a cast-iron skillet. For parties, cut it into bite-sized squares so guests can easily help themselves. Adding edible flowers or a dollop of whipped cream on top makes each serving look like a treat straight from a gourmet café.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which can be rare!), cover the casserole tightly with plastic wrap or transfer it to an airtight container. Store it in the refrigerator, and it will keep well for up to 3 days without losing its heavenly flavor or texture.

Freezing

The good news is you can freeze the cooked casserole! Slice it into portions, wrap each piece individually in plastic wrap, and place them in a freezer-safe bag or container. Freeze for up to 1 month. When you’re ready to enjoy, thaw overnight in the fridge before reheating.

Reheating

To bring your Banana Croissant “French Toast” Casserole back to life, reheat slices in a 350°F oven for 10 to 15 minutes or until warmed through. You can also use a microwave for convenience, though you might lose a bit of the crispy edges that make this dish so irresistible.

FAQs

Can I use fresh croissants instead of day-old?

Fresh croissants tend to be too soft and may get mushy when soaked. Using day-old croissants is ideal because they are firmer and can absorb the custard without falling apart, giving you that perfect texture contrast.

What if I don’t have banana extract? Can I skip it?

While banana extract adds a lovely boost to the banana flavor, you can definitely make this casserole without it. The fresh bananas still provide natural sweetness and flavor, but using the extract enhances the overall banana experience dramatically.

Can this casserole be made dairy-free?

Absolutely! Substitute the milk and heavy cream with your favorite plant-based alternatives like almond milk and coconut cream. Keep in mind that the texture will be slightly different, but it will still be deliciously satisfying.

Is there a way to make this recipe vegan?

This recipe relies on eggs and dairy for the custard, but you could experiment by replacing eggs with flax or chia “eggs” and using plant-based milks and creams. It might take some trial and error, but it’s definitely possible to create a vegan-inspired version.

Can I prepare this casserole the night before?

Yes! In fact, preparing it the night before allows the croissants to soak up all that custard overnight, deepening the flavors. Simply cover it and refrigerate, then bake it fresh in the morning.
