Overnight Baked Banana French Toast Casserole

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

6 slices of whole wheat or brioche bread, cut into cubes

2 ripe bananas, sliced

4 large eggs

1 ½ cups milk (dairy or non-dairy)

1 tablespoon vanilla extract

1 teaspoon ground cinnamon

2 tablespoons maple syrup

¼ cup brown sugar

Pinch of salt

2 tablespoons butter (for greasing the dish)

Directions

I start by greasing a 9x9-inch baking dish with butter and setting it aside.

Then, I layer the bread cubes and sliced bananas evenly in the dish.

In a bowl, I whisk together the eggs, milk, vanilla extract, cinnamon, maple syrup, brown sugar, and a pinch of salt.

I pour the egg mixture evenly over the bread and bananas, making sure everything is well soaked.

I cover the dish with plastic wrap or foil and refrigerate it overnight.

The next morning, I preheat the oven to 350°F (175°C), remove the cover, and bake for 35–40 minutes until the top is golden and the center is set.

I let it cool for a few minutes before serving and sometimes drizzle more maple syrup over the top.

Variations

I like switching things up depending on what I have. Sometimes I add chopped walnuts or pecans for crunch. If I’m in a chocolate mood, a handful of chocolate chips works beautifully. I’ve also tried it with strawberries instead of bananas and it was a fruity twist I’d definitely make again. For a dairy-free option, I simply use almond or oat milk and it still turns out delicious.

Storage/Reheating

Once baked, I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I just pop a portion in the microwave for 30–60 seconds or warm it in the oven at 300°F (150°C) for 10–15 minutes. It also freezes well—just slice it into portions, wrap tightly, and freeze for up to a month. I thaw it overnight in the fridge before reheating.

FAQs

How do I keep the casserole from getting soggy?

I make sure the bread is slightly stale or toasted before using it. This helps it soak up the egg mixture without getting mushy.

Can I make this without bananas?

Yes, I’ve swapped bananas with other fruits like apples, blueberries, or even pears. Just keep the fruit layer about the same volume.

Is it okay to use non-dairy milk?

Absolutely. I’ve used almond, oat, and soy milk with great results. It doesn’t affect the texture or flavor too much.

Can I assemble it the same morning?

It’s best if it sits overnight so the bread fully absorbs the custard, but in a pinch, I let it sit for at least 30 minutes before baking.

What kind of bread works best?

I like using whole wheat for a heartier texture or brioche for a richer, sweeter dish. French bread or challah also work wonderfully.

Conclusion

This Overnight Baked Banana French Toast Casserole is my breakfast dream come true—simple to prep, packed with flavor, and a real crowd-pleaser. Whether I’m hosting brunch or just craving something warm and comforting, this recipe never disappoints. It’s become a staple in my kitchen, and I bet it will be in yours too.
