Step‑by‑Step Instructions for Banana Croissant “French Toast” Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grab an 8×8-inch baking dish and lightly grease it with cooking spray to ensure your Banana Croissant “French Toast” Casserole comes out easily after baking.
Step 2: Whisk the Custard
In a large mixing bowl, combine whole milk, heavy cream, large eggs, granulated sugar, vanilla extract, banana extract, and a pinch of salt. Whisk these ingredients together until the mixture is smooth and well blended, creating a rich custard that will envelop your croissants.
Step 3: Soak the Croissants
Tear your day-old croissants into bite-sized pieces and gently add them to the custard mixture. Stir thoroughly, ensuring each piece is coated in the creamy custard. Allow the croissants to soak for about 25-30 minutes, stirring once halfway through to ensure even absorption.
Step 4: Add the Banana Slices
Once the croissants have soaked, pour the luxurious mixture into the prepared baking dish. Carefully nestle sliced ripe bananas into the layers, distributing them evenly throughout the casserole for that sweet, fruity goodness that pairs so well with the croissant base.
Step 5: Bake to Perfection
Place the baking dish in the preheated oven and bake for 45-50 minutes. You’ll know your Banana Croissant “French Toast” Casserole is done when the custard is set in the center, and the tops of the croissants have turned a beautiful golden brown, inviting you to dig in.
Step 6: Cool and Serve
After baking, remove the casserole from the oven and let it cool for about 10 minutes. This resting time allows the dish to firm up slightly, making it easier to slice and serve, so you can enjoy this delightful breakfast in all its glory!

Expert Tips for Banana Croissant Casserole
-
Use Day-Old Croissants: Ensure your croissants are at least a day old to maximize their absorption of the custard. Fresh croissants can turn mushy if used directly.

Proper Soaking Time: Allow the croissants to soak in the custard mixture for 25-30 minutes, stirring halfway through. This step is crucial for achieving that rich custardy texture.
-
Golden Brown Tops: Keep an eye on the baking time. A perfectly baked casserole will have a lightly browned top, indicating it’s time to take it out of the oven.
-
Cool Before Serving: Let the casserole rest for about 10 minutes after baking. This helps it firm up a bit, making it easier to slice and serve.
-

Banana Croissant French Toast Casserole Recipe FAQs
How do I select ripe bananas for this casserole?
Absolutely! Look for bananas that are mostly yellow with a few brown spots, indicating they’re ripe and sweet. Overripe bananas, with more brown than yellow, can also be used, as they add even more natural sweetness, making your casserole heavenly.
How should I store leftover Banana Croissant French Toast Casserole?
To keep your casserole fresh, cover it tightly with plastic wrap or place it in an airtight container. You can store it in the refrigerator for up to 2 days. Just a heads up—it’s best enjoyed fresh, but will still be delicious as leftovers!
Can I freeze the Banana Croissant French Toast Casserole?
Yes, you can! To freeze, cut the casserole into individual portions and wrap them tightly in plastic wrap, then place them in an airtight freezer bag. This way, they’ll stay good for up to 3 months. When you’re ready to enjoy, just thaw it overnight in the refrigerator and then reheat in the oven at 350°F for about 15-20 minutes.
What can I do if my casserole turns out too soggy?
Very! If your custard is too runny, it’s likely due to either using fresh croissants or not soaking them long enough. Make sure you use day-old croissants and allow them sufficient time to absorb the custard mixture—at least 25-30 minutes while stirring halfway through. This will help attain the perfect, custardy texture without being overly soggy.
Can I make this casserole vegan-friendly?
Most definitely! To make it vegan, replace the whole milk and heavy cream with almond or soy milk and use a flax egg or a commercial egg replacer instead of large eggs. You can still maintain that delightful texture by following the same soaking and baking procedures. Enjoy your delicious vegan Banana Croissant French Toast Casserole!
