This Overnight French Toast Casserole has been such a success at home. It is so comforting and delicious. The best part of this recipe is the convenience: you prepare the casserole in advance, and you can enjoy a hassle-free breakfast. Letting the casserole sit for the night helps the bread fully absorb the egg mixture, resulting in a rich, moist center with crispy, golden edges.

The best bread for an overnight French toast casserole is something that can hold its shape and texture after soaking overnight. I recommend using a baguette or French loaf. Try sourdough for a more rustic twist if you prefer a heartier flavor.

French Toast Casserole Recipe Ingredients
Ingredients
French Bread – Any crusty bread would work here. Those absorb the custard without ending up soggy.
Eggs – Ensure eggs are at room temperature for smoother blending with other ingredients.
Brown sugar – Any type of sugar would work. But if you’re out of brown sugar, you can get a similar flavor by mixing granulated sugar with a small amount of molasses.
Milk – Full-fat dairy will provide a creamier texture, while lighter milk may result in a slightly less rich dish.
Vanilla extract – For a more intense vanilla flavor, Swap with vanilla bean paste or the seeds from a vanilla pod. In a pinch, use maple syrup for a subtle twist on sweetness.
Ground cinnamon – This is the queen of the recipe; you can add a pinch of nutmeg or ginger for an extra autumn taste.
Apples – Use any type of apple you like, though Gala, Granny Smith, or Honeycrisp work best due to their balance of sweetness and tartness.
All-purpose flour – For gluten-free alternatives use gluten-free flour blends or even almond flour for a nuttier texture.
Unsalted butter – This is used for the topping; make sure it is cold to achieve a nice crumble.
Salt – Use the one you have on hand. Sea salt and Kosher salt are my first choices.
How to make French Toast Casserole
First, chop the bread into bite-size pieces. Core the apples and chop them into bite-size cubes. Set them aside while you prepare the egg custard.
Whisk the eggs, milk, brown sugar, vanilla extract, ground cinnamon, and salt in a large bowl.
Mix brown sugar, cinnamon, and salt in a separate bowl. Set aside for the moment.
Soak the bread cubes into the egg custard mixture. Make sure the bread is evenly coated.
Next, grease a 13×9-inch baking dish with butter.
Place soaked bread into the prepared baking dish, mix in apple cubes and toss to combine. Spread the cinnamon sugar mixture on top of the casserole and drop chopped butter over it.
Finally, cover it with aluminum foil and refrigerate it overnight.
On the next morning, preheat the oven to 375°F and bake the casserole for about 30 to 35 minutes or until the top is golden brown and the egg custard has set.
Let it cool for a few minutes before serving. My favorite add-ons when serving this casserole are powdered sugar, maple syrup, and ice cream. The warm and cool contrast is fantastic.
How To Store French Toast Casserole
First, allow the baked French toast to cool down to room temperature before storing. Then, use plastic wrap or transfer the casserole to an airtight container. Refrigerate it for up to three to four days.
You can reheat individual portions in the microwave or oven. For the oven, cover the dish with foil and bake at 350°F (175°C) for 15-20 minutes until warmed through.
Can you make an Overnight French Toast on the same day?
Of course, sitting overnight is optional. You can just bake it right after you assemble it. My recommendation is to let it sit for at least an hour for the bread to absorb the custard well.
What to Serve with French Toast Bake
You can add your favorite toppings; here are some ideas:
– Maple syrup: my personal choice!
– Fresh berries: they balance out the sweetness of this casserole or try this Fruit Salad with Honey Lime Dressing.
– Ice cream: go for a vanilla ice cream for best results.
– Whipped cream: it works wonderfully for added creaminess.
– Chopped nuts: for a crunchy bite.
