I love having breakfast completely prepared the night before and just having to pop it in the oven in the morning. One of my favorite overnight breakfast casseroles is my baked Bananas Foster French toast with caramelized bananas. It’s right up there with my overnight strawberry French toast casserole and my stuffed raspberry French toast. The bananas make it so decadent – just like eating Bananas Foster for breakfast!
Overnight French toast is made by soaking bread in milk and cream overnight so that that all of the liquid is absorbed. In the morning, you bake the recipe and end up with a super moist French toast that is almost like bread pudding.
To give the French toast a Bananas Foster flavor, I add caramelized bananas. Bananas Foster is a dessert where warm bananas fried in brown sugar, butter, and a little rum are served over ice cream.
For the French toast version, you could add the caramelized bananas as a French toast topping after it’s done baking – but in my recipe, I love to put them on the French toast before baking. That way, you get some baked in to every bite!
How to Make Overnight Bananas Foster French Toast Casserole
The two best breads to use for French toast are challah and brioche. They are both enriched breads, which means that they have eggs and fat in addition to flour, water, and yeast. Challah typically uses oil as the fat and brioche uses butter. While I absolutely love challah French toast, once I discovered brioche, there was no turning back.
Start by ripping brioche apart into a 6 cup baking dish such as a 10″ round or an 8″ square baking dish . The whole point is to break the bread up so it isn’t one big piece. The size of the pieces you end up with doesn’t really matter. Although many people prefer to use stale bread in their French toast, I find that fresh brioche works perfectly in this recipe. The end result is really moist, but not soggy.
Tip: I like baking in cast iron because it yields a rustic presentation, but any oven-safe dish is fine.
Top with caramelized bananas. Be sure to include all of the caramel sauce in the pan along with the bananas.
Read my guide to making caramelized bananas to learn more about how to prepare the topping. Did you know that you can make them in the microwave? It is super easy! Frying them is the best method, but in a pinch, the microwave works just fine.
Pour a mixture of eggs, milk, heavy whipping cream, sugar, spices, and vanilla over the top of the bread and caramelized bananas.
Then, cover the dish and refrigerate overnight so it’s ready to bake and serve in the morning.
Bake until there is no liquid remaining. If you see any liquid pooling at the top of the dish, it’s not done yet.
Tip: Food cooked in more shallow bakeware cooks more quickly. Since bakeware varies by brand, always keep an eye on your French toast as it nears completion to make sure it doesn’t get too dried out.
Bananas Foster French toast is sweet enough that it doesn’t need any topping, but if you want it to be extra decadent, it is SO good with a dollop of whipped cream on top!
Tip: Ideally, serve baked French toast hot out of the oven. Like a souffle, you’ll find that the French toast will look prettiest right out of the oven and will deflate some as it cools. If you need to reheat it, microwave individual pieces for about one minute or heat the whole casserole dish covered in the oven at 250 F for 30 minutes.
This French toast lasts about one week in the refrigerator or several months in the freezer if removed from the casserole dish and sealed in an airtight container.
Best Tips for Making Brioche French Toast
- Use fresh brioche for soft and custardy French toast.
- Whisk all of the wet ingredients really well so there are no separate cooked egg bits in the French toast.
- Food cooked in more shallow bakeware cooks more quickly. Since bakeware varies by brand, always keep an eye on your French toast as it nears completion to make sure it doesn’t get too dried out.
- Serve straight from the oven if possible. Like a souffle, you’ll find that the French toast will look prettiest right out of the oven and will deflate some as it cools.
