Ingredients
For the Casserole:
- 1 loaf French bread or brioche (about 12 oz), cut into 1-inch cubes
- 3 ripe bananas, sliced
- 6 large eggs
- 1 ¾ cups whole milk
- ½ cup heavy cream
- ½ cup brown sugar
- 2 tsp vanilla extract
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg
- Pinch of salt
For the Brown Sugar Banana Topping:
- 2 tbsp butter
- ¼ cup brown sugar
- 2 ripe bananas, sliced
Optional Garnish:
- Powdered sugar
- Chopped pecans or walnuts
- Maple syrup
Instructions
1. Prepare the Banana Topping
In a skillet, melt butter over medium heat. Add brown sugar and stir until bubbly. Add sliced bananas and cook for 1–2 minutes until soft and caramelized. Pour this mixture into the bottom of a greased 9×13-inch baking dish.
2. Layer the Bread
Add cubed bread on top of the banana mixture, spreading evenly.
3. Make the Custard
In a large bowl, whisk together eggs, milk, cream, brown sugar, vanilla, cinnamon, nutmeg, and salt until fully combined.
4. Pour & Chill
Pour the custard evenly over the bread cubes, pressing slightly to help the bread absorb the liquid. Cover and refrigerate for at least 1 hour or overnight for best results.
5. Bake
Preheat oven to 350°F (175°C). Remove the casserole from the fridge and let it sit at room temperature for 15–20 minutes. Bake uncovered for 40–45 minutes or until the top is golden brown and the center is set.
6. Serve
Let cool slightly before serving. Dust with powdered sugar, drizzle with maple syrup, or sprinkle with chopped nuts if desired.
