Step‑by‑Step Instructions for Baked Banana French Toast Casserole
Step 1: Grease the Dish
Start by preheating your oven to 350°F (176°C). While the oven heats, generously grease a 9×13 inch casserole dish with butter. This will ensure that your Baked Banana French Toast Casserole slides out easily once baked, preventing any sticky situations and making for a beautiful presentation.
Step 2: Prepare the Bread and Custard Mix
In a large mixing bowl, cut your challah or brioche bread into 1-inch chunks. Whisk together eggs, milk, heavy cream, brown sugar, vanilla extract, and cinnamon in another bowl until smooth. Pour this creamy custard mixture over the bread chunks, making sure each piece is well coated with the flavorful liquid to absorb throughout the night.
Step 3: Combine and Add Bananas
Gently fold the sliced, ripe bananas into the bread and custard mix, ensuring they get nicely coated. This step is crucial as the bananas will infuse sweetness and moisture into your Baked Banana French Toast Casserole. Be careful not to over-mix, as you want to maintain the lovely texture of the bread pieces.
Step 4: Refrigerate Overnight
Transfer the mixture into your greased casserole dish, spreading it out evenly. Cover with plastic wrap or a lid and refrigerate the dish overnight. This allows the bread to soak up the custard, creating a deliciously custardy texture that will be irresistible once baked.
Step 5: Bake the Casserole
The next morning, uncover the dish and place it in your preheated oven. Bake the Baked Banana French Toast Casserole for approximately 35-40 minutes until it’s golden brown on top and set in the middle. You can check doneness by inserting a knife — it should come out clean when the casserole is fully cooked.
Step 6: Prepare the Streusel Topping
While the casserole is baking, prepare the streusel topping. In a small bowl, combine brown sugar, all-purpose flour, cold cubed butter, and cinnamon. Use a fork or your fingers to mix until crumbly. Set aside until the casserole has about 5 minutes left to bake, ensuring the topping will become perfectly golden and crunchy on top.
Step 7: Add the Streusel Topping
Once the casserole has baked for 30-35 minutes and is almost done, sprinkle the prepared streusel topping evenly over the surface. Return it to the oven for the remaining 5-10 minutes until the topping is lightly browned and crisp. This final touch adds a delightful crunch, balancing the soft, custardy goodness beneath it.
Step 8: Serve and Enjoy
Remove the casserole from the oven and allow it to cool for a few minutes before slicing. Serve warm, drizzled with maple syrup or topped with whipped cream and fresh fruit for an added touch of sweetness. Your family will adore this comforting Baked Banana French Toast Casserole!
