How to Make Brown Sugar Banana French Toast Casserole?
Making this casserole is as simple as it gets. Follow these steps, and soon your kitchen will smell heavenly!
Step 1: Cook the Banana Filling 🍌
Start by melting butter in a skillet and stir in brown sugar, maple syrup, and a pinch of salt. Cook until smooth, then fold in sliced bananas. Once it cools slightly, the banana caramel mixture is ready to use.
Step 2: Assemble the Layers 🍞
Take a casserole dish and grease it. Layer half the bread cubes, spoon some banana filling over it, and then top with the other half. This layering creates the ultimate flavor combination in each bite!
Step 3: Prepare the Egg Custard 🥚
Whisk together eggs, milk, half-and-half, brown sugar, cinnamon, and vanilla extract. Pour this creamy mixture evenly over the bread. Press it down gently to soak everything well.
Step 4: Make the Crumble Topping 🍯
Combine flour, brown sugar, cinnamon, and butter until it forms sandy crumbs. Cover and refrigerate this until you’re ready to bake.
Step 5: Bake and Enjoy! 😋
Take the soaked casserole out of the refrigerator while preheating your oven to 350°F. Sprinkle the crumble topping evenly and bake for 40-55 minutes. It’ll puff up and turn golden brown. Serve warm with your favorite toppings like caramel sauce or whipped cream.

Tips for Making the Recipe
Here are some handy pointers to ensure your casserole turns out perfect every time.
- Use Day-Old Bread: Stale bread absorbs the custard better without becoming mushy, giving the dish the perfect texture.
- Don’t Skip the Overnight Chill: Allowing the bread to soak ensures it fully absorbs the custard, making every bite flavorful and moist.
- Taste and Adjust Sweetness: If you prefer it less sweet, slightly reduce the brown sugar in the filling or custard.
- Keep the Temperature in Check: Bake it uncovered, but if it browns too quickly, cover it loosely with foil to prevent over-crisping.
