Step‑by‑Step Instructions for Banana Croissant “French Toast” Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Banana Croissant French Toast Casserole bakes evenly and achieves the perfect golden-brown top. While the oven is heating, prepare an 8 x 8-inch baking dish by spraying it generously with cooking spray to prevent sticking.
Step 2: Whisk the Custard Mixture
In a large mixing bowl, combine whole milk, heavy cream, large eggs, granulated sugar, vanilla extract, banana extract, and a pinch of salt. Whisk the mixture thoroughly until it becomes smooth and uniform in color. This creamy custard will soak into the croissants, creating that rich, luscious texture you’re looking for.
Step 3: Soak the Croissants
Tear the day-old croissants into bite-sized pieces and gently fold them into the custard mixture, ensuring every piece is well-coated. Let this mixture sit for about 25-30 minutes, stirring halfway through to encourage even absorption. As the croissants soak, they will become fluffy and infused with the custard flavors.
Step 4: Add the Bananas
After soaking, carefully fold in sliced ripe bananas, distributing them evenly throughout the croissant and custard mixture. This will enhance the casserole with delightful bursts of banana flavor. Pour everything into your prepared baking dish, making sure the croissant pieces are nestled closely together for a beautifully cohesive bake.
Step 5: Bake to Perfection
Place the baking dish in your preheated oven and let the casserole bake for 45-50 minutes. Keep an eye on it towards the end; the custard should be set, and the tops of the croissants should turn a lovely golden-brown hue. This step is crucial to achieve that ideal custardy interior and slightly crisp exterior for your Banana Croissant French Toast Casserole.
Step 6: Cool Before Serving
Once baked, remove the casserole from the oven and allow it to cool for about 10 minutes. This resting time helps firm up the custard slightly, making it easier to serve. As it cools, the delightful aroma of bananas and warm croissants will fill your kitchen, promising a delightful breakfast experience.

Expert Tips for Banana Croissant French Toast Casserole
-
Soaking Time: Allow the croissant mixture to soak for the full 30 minutes. This ensures the custard fully penetrates the croissants, creating that desirable softness.

Prevent Over-browning: Keep an eye on the casserole during the last 10 minutes of baking. Cover it loosely with foil if it’s browning too quickly to avoid a burnt top.

Cool Down: Be sure to let the casserole cool for 10 minutes before serving. This helps it set up nicely, making it easier to slice and serve while maintaining its delightful custardy texture.

Banana Croissant French Toast Casserole Recipe FAQs
What type of croissants work best for this casserole?
Using day-old croissants is highly recommended as they absorb the custard mixture beautifully, creating a fluffy texture. Fresh croissants can work too, but they may require less soaking time since they’re softer and could disintegrate.

Store leftovers in an airtight container in the refrigerator for up to 3 days. Make sure to let it cool completely before transferring. When you’re ready to enjoy it again, simply reheat individual servings in the microwave or oven until warmed through.

What if my casserole turns out too soggy?
If your casserole is too soggy, it may be due to over-soaking the croissants or using too much custard liquid.
