Ingredients
For the French Toast Base:
- 1 large loaf brioche bread (about 1 pound), cut into 1-inch cubes
- 8 large eggs
- 2 cups whole milk
- 1 cup heavy cream
- 3/4 cup brown sugar, packed
- 2 tablespoons vanilla extract
- 1 tablespoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon salt
For the Caramelized Banana Layer:
- 4 tablespoons unsalted butter
- 2/3 cup brown sugar, packed
- 1/4 cup dark rum (or 1 tablespoon rum extract for alcohol-free version)
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 4-5 ripe bananas, sliced into 1/2-inch rounds
For the Topping:
- 1/2 cup chopped pecans or walnuts (optional)
- 2 tablespoons brown sugar
- 1/2 teaspoon ground cinnamon
For Serving:
- Maple syrup
- Additional sliced bananas
- Whipped cream
- Powdered sugar for dusting
Instructions
The Night Before:
- Grease a 9×13-inch baking dish with butter or cooking spray.
- In a large mixing bowl, whisk together eggs, milk, heavy cream, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
- Place the cubed brioche bread in the prepared baking dish.
- In a large skillet over medium heat, melt butter. Add brown sugar and stir until dissolved, about 2-3 minutes.
- Add rum (stand back as it may flame briefly) or rum extract, vanilla, and cinnamon. Stir to combine.
- Add sliced bananas to the skillet and gently toss to coat with the caramel sauce. Cook for 2-3 minutes until bananas start to soften but still hold their shape.
- Pour the caramelized banana mixture evenly over the bread cubes.
- Pour the egg mixture over the bread and bananas, making sure all bread pieces are soaked.
- Cover with plastic wrap and refrigerate overnight (at least 8 hours).
In the Morning:
- Remove the casserole from the refrigerator and let it sit at room temperature while you preheat the oven to 350°F (175°C).
- In a small bowl, mix together the chopped nuts (if using), brown sugar, and cinnamon for the topping.
- Sprinkle the topping mixture evenly over the casserole.
- Bake uncovered for 45-55 minutes until the top is golden brown and the center is set (but still slightly jiggly).
- Let stand for 10 minutes before serving.
- Serve warm with maple syrup, additional sliced bananas, whipped cream, and a dusting of powdered sugar if desired.
The key to achieving the perfect texture in this casserole is using slightly stale bread, as it will better absorb the custard without becoming too soggy. If your brioche is fresh, you can cube it and leave it out for a few hours to dry slightly before assembling the casserole. Alternatively, you can toast the bread cubes in a 350°F oven for about 10 minutes – just enough to dry them out without browning them too much.
When selecting bananas for this recipe, look for ones that are ripe but still firm. They should have bright yellow peels with some brown spots, indicating peak ripeness and sweetness. Overly soft or brown bananas will break down too much during the caramelizing process and turn mushy in the casserole. If you’re planning ahead, buy slightly underripe bananas a few days before you plan to make the dish and let them ripen at room temperature.
Recipe Variations
This Bananas Foster French Toast Casserole is incredibly versatile. Here are some delicious variations to consider:
- Chocolate Lover’s Version: Add 1 cup of chocolate chips to the layers for a decadent chocolate-banana combination.
- Coconut Paradise: Mix 1 cup of shredded coconut into the custard and sprinkle some on top for a tropical twist.
- Bourbon Alternative: Substitute bourbon for rum in the caramel sauce for a different flavor profile.
- Berry Addition: Add 1 cup of fresh berries (strawberries, blueberries, or raspberries) between the layers for extra fruity goodness.
- Cream Cheese Surprise: Dot small pieces of cream cheese between the bread cubes for pockets of creamy richness.
Make It Ahead Tips
While this casserole is designed to be prepared the night before, you can actually make it up to 2 days in advance. Simply keep it covered in the refrigerator until you’re ready to bake. You can also freeze the unbaked casserole for up to 1 month. When ready to serve, thaw in the refrigerator overnight, then let it stand at room temperature for 30 minutes before baking as directed, adding an extra 10-15 minutes to the baking time if needed.
