Step‑by‑Step Instructions for Banana Croissant French Toast Casserole
Step 1: Preheat and Prep
Begin by preheating your oven to 350°F (175°C). While it heats, generously grease an 8 x 8-inch baking dish with butter or cooking spray to prevent sticking. Setting the stage with a well-prepared dish ensures your delicious Banana Croissant French Toast Casserole will come out beautifully!
Step 2: Whisk the Custard
In a large mixing bowl, whisk together whole milk and heavy cream until fully combined. Add eggs, granulated sugar, vanilla extract, banana extract, and a pinch of salt, mixing thoroughly for a smooth custard base. This rich mixture will envelop the croissants with flavor and create that beloved creamy texture.
Step 3: Coat the Croissants
Tear the day-old croissants into bite-size pieces and gently fold them into the custard mixture. Ensure every piece is coated well, soaking up the creamy goodness. Allow the mixture to rest for 25-30 minutes, stirring halfway through to keep those croissant pieces evenly immersed and flavorful.
Step 4: Assemble the Casserole
Pour the croissant and custard mixture into your prepared baking dish, spreading it out evenly for uniform baking. Take ripe banana slices and arrange them beautifully on top, creating an inviting look. This delightful layering not only enhances the flavor but also offers a lovely visual appeal for your Banana Croissant French Toast Casserole.
Step 5: Bake to Perfection
Place the baking dish in your preheated oven and bake for 45-50 minutes. Keep an eye on it; the casserole should be puffed up and lightly browned on top when done. The custard should set, giving you that perfect balance of fluffy croissant and creamy custard.
Step 6: Cool and Serve
Once baked, remove the Banana Croissant French Toast Casserole from the oven and let it cool for about 10 minutes. This resting time helps it firm up a bit, making it easier to slice. Serve warm, drizzling with maple syrup for a delightful finish that will surely impress your family and friends.

Banana Croissant French Toast Casserole Recipe FAQs
What type of bananas should I use?
Absolutely! For this casserole, you’ll want ripe bananas that are slightly speckled; these will provide the best natural sweetness and flavor. If your bananas are still green, simply let them sit at room temperature for a few days. You could also use overripe bananas, which are ideal for mashing and incorporating into baked goods because they’re extra sweet!
How should I store leftovers?
Very! Leftovers are best stored in an airtight container in the refrigerator for up to 3 days. Make sure to cool the casserole completely before transferring it to help preserve its delicious flavor and texture. If you plan to enjoy it later, simply reheat it in the oven at 350°F (175°C) for about 15-20 minutes or in the microwave for 1-2 minutes until heated through.
Can I freeze the casserole?
Absolutely! To freeze, slice the cooled casserole into individual portions and wrap each slice tightly in plastic wrap, followed by aluminum foil. This will help prevent freezer burn. You can freeze the portions for up to 2 months! When you’re ready to enjoy them, simply thaw in the refrigerator overnight and reheat as mentioned above.
What if my casserole turns out soggy?
Don’t worry! If your Banana Croissant French Toast Casserole comes out soggy, it could be due to several factors. Ensure you’re using day-old croissants, which absorb the custard better without becoming overly mushy. If using fresh croissants, reduce soaking time to about 15 minutes. Additionally, check that you’re baking long enough for the custard to set—cooking it for the full 45-50 minutes is key to achieving that perfect custardy texture without excess moisture.
Is this recipe suitable for anyone with gluten allergies?
Great question! If you’re catering to gluten-sensitive or gluten-intolerant individuals, unfortunately, traditional croissants contain gluten. You can opt for gluten-free croissants or other gluten-free bread alternatives to cater to dietary needs. Just ensure that any substitutes align with the same soaking method and baking time for optimal results.
