Step‑by‑Step Instructions for Banana Croissant French Toast Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C) while you gather your ingredients. Spray an 8 x 8-inch baking dish with cooking spray to ensure easy removal after baking. This preheating step is crucial for even cooking and achieving that golden top on your Banana Croissant French Toast Casserole.
Step 2: Mix Custard
In a large mixing bowl, whisk together 2 cups of whole milk, 1 cup of heavy cream, 4 large eggs, ½ cup of granulated sugar, 1 teaspoon of vanilla extract, 1 teaspoon of banana extract, and a pinch of salt. Stir until all the ingredients blend smoothly, creating a rich custard mixture to soak your croissants in. You’ll want it to look creamy and well-combined, ready for the next step.
Step 3: Soak Croissants
Tear day-old croissants into bite-sized pieces and gently fold them into the custard mixture. Ensure all pieces are fully coated as the custard is absorbed. Allow the mixture to sit for about 25-30 minutes, stirring gently halfway through. This soaking time is essential for the bread to become deliciously custardy, perfect for your French Toast Banana Croissant delight.
Step 4: Prepare Baking Dish
After the croissant pieces have soaked up the custard, pour the entire mixture into your prepared baking pan. Nestle slices of ripe banana among the croissant pieces, ensuring they are evenly distributed throughout. This step not only adds sweetness but also enhances the flavor and texture of the casserole.
Step 5: Bake
Place your baking dish in the preheated oven and bake for 45-50 minutes. Keep an eye on it; the casserole should puff up and turn a light golden brown when done. To check for doneness, insert a knife into the center, and it should come out clean. This is how you know your Banana Croissant French Toast Casserole is perfectly set!
Step 6: Cool Slightly
Once baked, remove the casserole from the oven and let it sit for about 10 minutes. This cooling period helps the casserole to firm up slightly, making it easier to slice. The aroma will be irresistible, inviting everyone to gather around for a deliciously warm breakfast treat.

Expert Tips for Banana Croissant Casserole
- Choose Day-Old Croissants: Using stale croissants is key for absorbing the custard. Fresh ones may turn soggy instead of perfectly soaked.
- Don’t Over-Mix: When combining your croissants with the custard, be gentle. Over-mixing can lead to a mushy texture in your French Toast Banana Croissant.
- Let it Soak: Allowing the croissant mixture to sit for at least 25-30 minutes ensures every bite is custardy and flavorful. Don’t rush this step!
- Check for Doneness: Insert a knife in the center; it should come out clean once the casserole is baked properly. If it’s wet, keep baking for a few more minutes.
- Add Toppings: Consider sprinkling nuts or chocolate chips over the top before baking for extra flavor and crunch in your casserole.
- Serve Warm: This dish is best enjoyed fresh out of the oven, warm and drizzled with maple syrup for added indulgence.
Storage Tips for French Toast Banana Croissant
Fridge: Store any leftovers in an airtight container, where they will keep for up to 3 days. Reheat individual portions in the microwave or in the oven at 350°F until warmed through.
Freezer: If you want to save some for later, freeze slices in a freezer-safe container for up to 2 months. Wrap each slice tightly in plastic wrap before placing in the container.
Reheating: For best texture, thaw frozen slices overnight in the fridge before reheating in the oven at 350°F for about 15-20 minutes, or until warmed and crispy on top.
Make-Ahead: You can prepare the French Toast Banana Croissant casserole the night before, covering it tightly before refrigerating. Just bake it fresh in the morning for a delicious brunch treat!
Make Ahead Options
These Banana Croissant French Toast Casserole variants are perfect for meal prep enthusiasts! You can prepare the custard mixture up to 24 hours in advance and store it in the refrigerator, ensuring flavors meld beautifully. Tear your stale croissants and mix them in just before baking to prevent them from becoming too soggy. The ripe bananas can also be sliced and ready up to 3 days ahead—just toss them in a bit of lemon juice to maintain their lovely color. When you’re set to enjoy this delicious dish, pour the custard over the croissants, nestle the bananas, and bake as directed. It makes for a stress-free, mouthwatering brunch that rivals any cafe treat!

Banana Croissant French Toast Casserole Recipe FAQs
What type of croissants should I use for the casserole?
Absolutely, I recommend using day-old croissants to achieve the best texture. Fresh croissants may not absorb the custard properly, leading to a soggier result. Stale croissants soak up the flavors beautifully while maintaining their flaky texture.
How should I store leftovers from the casserole?
For sure! Any leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Just make sure they’ve cooled completely before sealing. Reheat individual portions in the microwave, or pop them in the oven at 350°F for best results.
Can I freeze the French Toast Banana Croissant casserole?
Yes, you can! To freeze, slice the casserole first and wrap each piece tightly in plastic wrap. Place them in a freezer-safe container or bag. It will keep well in the freezer for up to 2 months. When you’re ready to enjoy, thaw it overnight in the fridge and reheat in the oven.
What if the custard mixture is too runny after baking?
The key here is to ensure that you bake it long enough; if the custard appears runny, simply allow a few additional minutes in the oven. Another tip is to check doneness by inserting a knife into the center; it should come out clean when fully baked. If it’s not set, continue baking until it firms up.
Can I make this casserole dairy-free?
Very much! To make a dairy-free version, substitute whole milk with almond or oat milk and heavy cream with coconut cream. Ensure that the other ingredients, especially the custard components, don’t contain dairy. Your casserole will still be deliciously creamy!
