This lighter, make-ahead overnight baked French toast casserole topped with Bananas Foster is perfect for Easter morning or any special brunch. The challah soaks in a vanilla-cinnamon custard overnight, and a quick warm bananas foster topping elevates the dish into something that’s almost dessert-worthy. It’s simple to prepare the night before, bakes the next morning, and feeds a crowd with minimal morning effort.
Bananas Foster French Toast
The challah (or brioche) soaks up the egg and milk custard, enriched with vanilla and cinnamon, creating a tender, bread-pudding-like center. Refrigerate the assembled casserole overnight so the bread fully absorbs the custard. In the morning, bake until puffed and lightly golden, then finish with a warm bananas foster topping made from butter, brown sugar, and ripe bananas. For an alcohol-free version, substitute rum extract for rum.
Why This Overnight French Toast Recipe Works
This recipe was inspired by a classic Crème Brûlée French toast topped with Bananas Foster. To keep it lighter, the added sugar has been reduced and a zero-calorie sweetener option is offered. Making it the night before saves time on busy mornings while intensifying the flavor as the bread soaks overnight. It’s cozy, crowd-pleasing, and makes a memorable brunch centerpiece.
- Easy make-ahead breakfast: Assemble the casserole the night before; the flavor improves with time.
- Lower added sugar: Options such as monk fruit sweetener reduce added sugar while keeping sweetness.
- Holiday-friendly: The rich aroma and presentation make this ideal for special mornings like Easter or Christmas.
- Rum optional: Swap rum extract for the liquor if you prefer to avoid alcohol.

How to Make Bananas Foster French Toast
Assemble the French toast casserole the night before so the bread soaks thoroughly. While the casserole bakes in the morning, prepare the bananas foster topping on the stovetop. Follow the printable recipe steps in the recipe section below for exact measurements and timing.
- Prepare the pan: Spray a 13 x 9-inch baking dish with oil or cooking spray and arrange bread slices in an even layer.
- Make the custard: In a large bowl, whisk together eggs, milk, vanilla, cinnamon, sweetener, salt, and rum extract (if using). Pour evenly over the bread.
- Chill overnight: Cover and refrigerate at least 8 hours or overnight to let the bread absorb the custard.
- Bake: Remove the dish from the fridge while the oven preheats to 350°F. Bake uncovered for 40–45 minutes, until puffed and edges are lightly golden.
- Bananas Foster topping: In a large, deep skillet, melt butter over low heat. Stir in brown sugar, cinnamon, and vanilla; add rum or rum extract if desired. Simmer about 2 minutes until slightly thickened, adding a splash of water if necessary, then add sliced bananas and simmer 1 minute. Remove from heat and keep covered until ready to serve.
- Serve: Cut the casserole into 8 portions and spoon warm bananas over each slice.
Variations & Tips
- Bread choices: Replace challah with a round country loaf, French bread, brioche, or Hawaiian rolls.
- Gluten-free: Use gluten-free bread if needed.
- Milk options: Any milk works—skim, 2%, whole, or a dairy-free alternative like almond or oat milk.
- Dairy-free version: Use plant-based milk and vegan butter for the banana sauce.
- Short on time? If you can’t refrigerate overnight, let the bread soak for a few hours; overnight yields the best texture and flavor.
- Feeding more people: Double the recipe and use two 9 x 13-inch pans.
