đź“Ś French Toast Bananas Foster
Posted 28 March 2026 by: Admin
On Friday night, you spend twenty minutes in the kitchen. On Saturday morning, you slide the dish into the oven and prep your bananas while it bakes. The house is going to smell like cinnamon and buttered caramel — and people will get out of bed all by themselves.
In the dish, the challah has soaked up all the custard overnight and puffed up slightly. Out of the oven, it forms a golden crust like cooked sugar, a bit darker around the edges. On top, the bananas glisten in their amber sauce, almost translucent. Under the fork, it gives way like a flan — moist at the heart, slightly caramelized on the surface.

Ingredient Notes
Challah bread, very ripe bananas, and some pantry essentials: that’s all you need.
- Challah bread : This is the base, and it’s where everything happens. Challah is slightly sweet, rich in eggs, and its tight crumb absorbs the custard without disintegrating. Get it from the day before — a slightly stale bread drinks the liquid even better. If you can’t find any, brioche or a dense-crumb country bread will do perfectly.
- Rum extract : A few drops are enough. This is what gives that mysterious sweet-spicy depth to the banana sauce. No alcohol, all the flavor — and frankly, the difference from real rum is imperceptible once cooked.
- Bananas : Get them very ripe, with little black spots on the skin. Less firm, they caramelize better and their flesh becomes creamy under the heat. Green bananas would stay hard and lack natural sweetness.
- Brown sugar : It melts into the butter and forms that liquid brown caramel that coats the bananas. Basic brown sugar works very well. You can also use coconut sugar for a slightly deeper taste, with less sugary bitterness.
- Cinnamon : It comes in twice: in the custard to flavor the bread, and in the banana sauce. Use Ceylon cinnamon if you have it — it’s sweeter and less aggressive than the Cassia cinnamon found everywhere.
The night before, twenty minutes and you’re done
Cut the challah into thick slices — at least two centimeters — and arrange them in a large, lightly greased baking dish. No need to make them fit perfectly; a few overlaps are fine. In a bowl, whisk the eggs with the milk, vanilla, cinnamon, a pinch of salt, and a few drops of rum extract. The smell at this stage is already there — sweet, vanillery, with that spicy cinnamon undertone that tickles the nose. Pour everything over the bread, wrap the dish in film, and put it in the fridge. The bread will drink the liquid overnight, and the next morning it will be swollen, dense, and ready to bake.
In the oven, unattended
Take the dish out of the fridge twenty minutes before turning on the oven to 175°C. This time to come back to temperature matters — an icy dish takes much longer to bake and the center often stays undercooked. Bake uncovered for 40 to 45 minutes. The edges start browning first, then the surface colors gradually until it reaches that amber brown, firm to the touch. Poke a knife in the center: it should come out clean, without liquid. If the top browns too quickly during baking, loosely place a piece of aluminum foil over it.
The bananas, quick and spectacular
You deal with these during the last ten minutes of baking. In a large skillet over low heat, melt the butter until it slightly foams and gives off that toasted hazelnut smell. Add the brown sugar, cinnamon, and rum extract — it sizzles gently and the sugar dissolves in less than a minute. Let simmer for two minutes: the sauce thickens and takes on a deep copper color. Add the sliced bananas and leave them for just a minute, no more. You want to feel them yield under the spoon, not see them fall into mush.
Serve while it’s hot
Cut the casserole into eight portions. The inside is moist like a pudding, the bottom slightly crispy where the dish heated directly. Place the bananas on top with their sauce — it gently seeps into the bread and runs down the sides. Eat this now. Not in five minutes. Now.
Tips & Tricks
- If your challah is fresh from the day, put the slices in the oven for ten minutes at 150°C before using them. They will dry out a bit and absorb the custard much better — bread that is too wet results in a pasty, compact casserole.
- Don’t skip the step of twenty minutes at room temperature before baking. The difference in baking between the center and the edges is much more marked with a dish taken directly from the fridge.
- Leftovers can be reheated in a pan with a splash of water — it rehydrates the bread and the surface becomes crispy again. In the microwave, the texture goes completely in the wrong direction.
How long should the bread soak before baking?
A full night, or a minimum of 8 hours. This is the time needed for the challah to absorb all the custard without staying dry in the center. If you’re in a hurry, 3 to 4 hours will do the trick, but the result will be a bit less moist.
Can I use a different bread than challah?
Yes. Brioche is the closest alternative. A dense-crumb country bread also works very well. Avoid sandwich breads that are too light — they disintegrate in the custard and yield a pasty texture.
How to store and reheat leftovers?
The casserole keeps for 3 days in the fridge, without the banana sauce. To reheat, warm the portions in a pan over medium heat with a splash of water — the surface becomes crispy again. Make the banana sauce fresh when serving, as it does not store well.
How do I know if the casserole is properly cooked?
Poke a knife in the center: it should come out clean, without liquid. The surface should be firm and golden, and the edges slightly pulled away from the dish. If the top browns too quickly, cover it with a piece of aluminum foil during baking.
Can I freeze this casserole?
Yes, the baked casserole (without the banana sauce) can be frozen for up to 2 months. Thaw overnight in the fridge and reheat in the oven at 160°C for 20 minutes. Prepare the banana sauce at the time of serving.
Can the bananas be prepared in advance?
No, not really. The banana sauce takes 5 minutes and should be served hot — when cooled, it loses its syrupy texture and the bananas turn black. It’s best to make it during the final minutes of the dish’s baking.

Breakfast / Brunch
A challah bread casserole soaked in vanilla-cinnamon custard, baked in the oven, and topped with bananas caramelized in brown sugar. It’s prepared the night before — in the morning, all you have to do is bake it.
Ingredients
- 500g day-old challah bread, cut into 2cm slices
- 4 eggs
- 350ml milk (whole or semi-skimmed)
- 2 tsp vanilla extract
- 1.5 tsp ground cinnamon
- 40g (3 tbsp) granulated sugar
- 1 pinch salt
- 1 tsp rum extract
- 30g (2 tbsp) unsalted butter
- 60g (4 tbsp) brown sugar
- 0.5 tsp ground cinnamon (for the sauce)
- 0.5 tsp vanilla extract (for the sauce)
- 0.5 tsp rum extract (for the sauce)
- 4 very ripe bananas, sliced
Instructions
- 1Lightly grease a 33x23cm baking dish. Arrange the challah slices in an even layer, overlapping them slightly.
- 2Whisk together the eggs, milk, vanilla, cinnamon, sugar, salt, and rum extract until you have a smooth custard.
- 3Pour the custard evenly over the bread. Wrap the dish and refrigerate for at least 8 hours.
- 4The next day, take the dish out of the fridge 20 minutes before baking. Preheat the oven to 175°C.
- 5Bake uncovered for 40 to 45 minutes, until the surface is golden and a knife inserted in the center comes out clean.
- 6Ten minutes before the end, melt the butter over low heat in a large skillet. Add the brown sugar, cinnamon, vanilla, and rum extract. Simmer for 2 minutes while stirring.
- 7Add the banana slices and cook for 1 minute without stirring too much, until they are tender and well coated with sauce.
- 8Cut the casserole into 8 portions, top each with bananas and sauce. Serve immediately.
Notes
• Stale bread recommended: day-old challah absorbs the custard better. If your bread is fresh, dry the slices for 10 minutes in the oven at 150°C before using them.
• Storage: the baked casserole keeps for 3 days in the fridge. Reheat in a pan with a splash of water to regain a crispy surface. Prepare the banana sauce fresh when serving.
• Freezing: the baked casserole (without sauce) can be frozen for up to 2 months. Thaw overnight in the fridge and reheat in the oven at 160°C for 20 minutes.
