About this caramel banana French toast casserole
Flavor-wise, this caramel banana French toast casserole is a little reminiscent of bananas Foster, but without the alcohol. You’ll make a caramel mixture with butter and brown sugar, then stir in sliced bananas.
The bread cubes are soaked in a vanilla-and-cinnamon infused custard, and the whole thing is topped with buttery streusel—you know, the kind you can’t resist picking at every time you walk by the casserole as it cools.
If this all sounds amazing, that’s because it is. This is the kind of special occasion breakfast that will wow everyone who tries it. Get ready to share the recipe, because everyone will be asking for it!
What you need
- Banana caramel filling: Butter, brown sugar, ripe bananas
- French toast: French bread, eggs, milk, half-and-half, vanilla extract, ground cinnamon
- Topping: All-purpose flour, brown sugar, butter
You can use either dark brown sugar or light brown sugar. Dark brown sugar has a deeper molasses flavor, while light brown sugar is, as its name suggests, lighter and milder.
How to make it
Make the filling. Melt the butter and brown sugar in a medium skillet set over medium heat. Stir and cook until the sugar dissolves, then remove from heat and stir in the bananas.
Tip: If you’d like, you can slightly mash the bananas and then fold the mashed bananas into the caramel.
Make the custard mixture. Whisk the eggs, milk, half-and-half, vanilla extract, and cinnamon in a large mixing bowl until the mixture is completely smooth.
Assemble. Grease a 9×13-inch baking dish with butter or cooking spray. Layer half the bread into the bottom of the dish.
Pour the banana caramel filling over the top.
Layer the remaining bread on top of the filling, then pour the custard into the dish.
Cover and refrigerate for a minimum of 4 hours, or overnight.
Make the topping. Whisk together the flour and brown sugar in a small bowl, then work the butter into the mixture using your fingers or a fork until it’s crumbly. Refrigerate the streusel until you’re ready to bake the casserole.
Bake. Remove the baking dish from the refrigerator and begin preheating your oven to 350ºF. Sprinkle the streusel over the top.
Bake for 35 to 40 minutes, or until the edges of the French toast casserole are golden brown. Let the casserole rest for 5 to 10 minutes, then serve.
If your bread is too fresh, you may end up with a soggy French toast casserole. For best results, use day old bread and allow the bread to soak up the custard mixture overnight. If you’re starting with fresh bread, dry it out in the oven first by baking it at 325ºF until it’s lightly toasted.
Serve this caramel banana French toast casserole with a drizzle of maple syrup or caramel, a dollop of whipped cream, or scatter some sliced bananas or toasted pecans over the top. You might want to pair it with a savory side like bacon, sausage, or scrambled eggs, or something light and healthy like fresh fruit.
I love French bread for French toast casserole, but you can also use sourdough, brioche, Italian, or challah bread.
How to make this caramel banana French toast casserole your own
Want to make some changes to this caramel banana French toast casserole? You can! Here are some ideas.
- Make it nutty. Mix ½ cup of chopped nuts into the crumb topping. Pecans or walnuts would work well.
- Make it chocolatey. Scatter mini chocolate chips or chopped dark chocolate over the filling layer before adding the remaining bread. Top with chocolate syrup.
- Make it with different fruit. Sliced apples would be delicious, or you could use pineapple for a flavor a little bit like pineapple upside down cake.
- Make it without half-and-half or milk. Using a mixture of milk and half-and-half creates a custard that is creamy and rich, without being too thick. However, if you do not have both then you can use one kind of dairy by substituting an equal part of the other.
Make Ahead Ideas
The custard should soak in the bread for at least 2 hours. If you are serving this for brunch then you can put it together earlier that same morning, but it is best when prepared the night before.
