For me, that’s this Overnight French Toast Casserole.

I’d assembled it the night before, feeling a pang of doubt wondering if it would actually turn out as good as I hoped. Fast forward to the next morning, pulling it out of the oven, golden brown and bubbling… let’s just say my husband declared it a new family favorite before he even took his first bite.

So, what exactly *is* an Overnight French Toast Casserole? At its heart, it’s taking all the wonderful elements of your favorite French toast – that custardy eggy bread, the warm spices, the sweet finish – and making it an absolute breeze to prepare ahead of time. Instead of standing over a hot griddle, flipping slices one by one, you assemble everything in a baking dish the night before. The bread gets a chance to soak up all the delicious custard mixture, infusing it deeply with flavor. Then, you pop it in the fridge, and when you’re ready to serve, it just needs a bake in the oven until it’s puffed up, golden, and utterly irresistible. It’s essentially a baked French toast where the “overnight” part is key to achieving that perfect, tender, and flavorful result without any last-minute fuss. It’s a clever little trick that makes busy mornings feel like a luxury.

How do I make a French Toast casserole?
Quick Overview
The beauty of this Overnight French Toast Casserole lies in its effortless preparation. You’ll simply cube your favorite bread, whisk together a rich custard, pour it over the bread, let it soak overnight in the fridge, and then bake it to golden perfection in the morning. The long soak is what makes the bread incredibly tender and allows all those delicious flavors to meld beautifully. It’s practically foolproof, even if you’re new to baking. You’ll wake up to a house that smells like a bakery, with minimal effort required.
Ingredients
For the Main Batter:
This is the heart of our casserole, the creamy, custardy goodness that makes French toast so divine. I always opt for a slightly stale challah or brioche bread because its rich eggy texture holds up beautifully and absorbs the custard without getting soggy. If you can’t find those, a good quality white bread or even Texas toast works wonders. Just make sure it’s not too fresh; a day or two old is perfect. You’ll need about 8 cups of cubed bread. For the custard itself, I use 6 large eggs – they provide that essential richness. Then, 2 cups of whole milk are essential for that classic creamy texture. You can experiment with half-and-half for an even more decadent result, or even almond milk if you prefer, though I tested this with almond milk and it actually made it even creamier! For flavor, 1 teaspoon of pure vanilla extract is non-negotiable, and 1 teaspoon of ground cinnamon brings that warm, cozy spice. A pinch of salt enhances all the other flavors. Some people add a whisper of nutmeg, and I highly recommend it for that extra layer of warmth, maybe about a quarter teaspoon.
For the Filling:
This is where you can really have some fun and customize it to your liking! I often just keep it simple with a sprinkle of brown sugar over the soaked bread before baking to give it a nice caramelization, about 1/4 cup. But if you’re feeling adventurous, you can add in 1 cup of fresh or frozen berries (like blueberries or raspberries), or even 1/2 cup of chocolate chips. For a nutty crunch, a handful of chopped pecans or walnuts works beautifully. Some days, I swirl in a tablespoon or two of good quality jam right before baking, like raspberry or apricot, for a fruity surprise. Just remember not to overdo it, as you don’t want to make the casserole too wet or heavy.
For the Glaze:
This is the crowning glory, the sweet finish that ties everything together. The simplest glaze is just powdered sugar mixed with a few tablespoons of milk or cream until it reaches your desired drizzling consistency. I usually start with about 1 cup of powdered sugar and add the liquid a tablespoon at a time until it’s perfect. For a little extra zing, I’ll add a tiny splash of lemon juice or a bit more vanilla extract. If you want a richer glaze, you can use a cream cheese base, or even a maple glaze by whisking together powdered sugar with pure maple syrup and a touch of butter.

Step-by-Step Instructions
Step 1: Preheat & Prep Pan
First things first, let’s get that oven ready. You’ll want to preheat your oven to 375°F (190°C). While that’s heating up, grab a 9×13 inch baking dish. It’s crucial to grease this dish really well. I like to use butter or cooking spray, and then I often sprinkle a tiny bit of granulated sugar over the buttered surface. This does two things: it prevents sticking and gives the bottom of the casserole a lovely, slightly crisp edge. I learned this trick after one too many times of the casserole trying to cling to the pan for dear life!
Step 2: Mix Dry Ingredients
In a large bowl, combine your cubed bread. If you’re adding any dry mix-ins like chocolate chips or nuts, this is a good time to toss them in gently with the bread. Make sure the cubes are evenly distributed. Don’t worry too much about them being perfectly uniform; a little variation adds to the rustic charm.
Step 3: Mix Wet Ingredients
In a separate, medium-sized bowl, whisk together your eggs. Once they’re well beaten, add the milk, vanilla extract, cinnamon, salt, and nutmeg (if using). Whisk until everything is thoroughly combined and you have a smooth, pale yellow custard. It’s important that there are no streaks of egg white or yolk left; we want a uniform mixture for even soaking.
Step 4: Combine
Now for the magic part! Pour the wet custard mixture evenly over the cubed bread in the large bowl. Gently fold and toss the bread with a spatula or your hands until all the pieces are coated. You want every single piece of bread to get a good soak. Don’t be afraid to get in there and make sure the bottom pieces are getting their fair share. Once everything is nicely coated, carefully transfer the bread and custard mixture into your prepared baking dish. Spread it out evenly.
Step 5: Prepare Filling
If you’re adding any fresh or frozen fruit, now’s the time to gently scatter them over the bread mixture in the baking dish. If you’re using jam, you can dot spoonfuls over the top and then gently swirl it in with a knife or skewer, but don’t over-mix, you want visible swirls. Sprinkle your brown sugar evenly over the top of the entire casserole. This is what gives you those lovely caramelized, crispy edges. If you’re adding nuts, sprinkle those on now too.
Step 6: Layer & Swirl
This step is more about distributing your chosen additions. If you’re using berries or chocolate chips, just scatter them evenly over the bread mixture. If you’re opting for a jam swirl, use a knife or a skewer to gently drag the jam through the top layer of bread. The goal here isn’t to incorporate it fully but to create beautiful pockets of flavor. Then, sprinkle the brown sugar evenly over the entire surface. This is going to create that delightful crunchy, caramelized topping. If you’re adding nuts, this is also when they go on.
Step 7: Bake
Cover the baking dish tightly with plastic wrap or foil. Place it in the refrigerator and let it soak for at least 4 hours, but ideally overnight. This is the key to that incredibly tender, custardy texture. When you’re ready to bake, remove the plastic wrap and place the dish in the preheated oven. Bake for 35-45 minutes, or until the casserole is puffed up, golden brown, and a knife inserted into the center comes out clean. If you notice the top browning too quickly, you can always loosely tent it with foil.
Step 8: Cool & Glaze
Once it’s out of the oven, let the casserole cool in the dish for about 10-15 minutes. This resting period is crucial; it allows the custard to set up properly, making it easier to slice. While it’s cooling, prepare your glaze. In a small bowl, whisk together the powdered sugar with enough milk or cream (about 2-3 tablespoons, add it slowly!) until you reach a pourable consistency. Once the casserole has rested, drizzle the glaze generously over the top. You can make it as thick or as thin as you like!

Step 9: Slice & Serve
Now for the best part! Cut the Overnight French Toast Casserole into squares and serve warm. It’s absolutely divine on its own, but you can also serve it with a dusting of powdered sugar, fresh berries, or a dollop of whipped cream. A side of crispy bacon or sausage makes it a complete brunch feast. The smell alone will have everyone asking for seconds!
What to Serve It With
This Overnight French Toast Casserole is so versatile, it’s practically a chameleon in the breakfast and brunch world! For a simple, comforting Breakfast, I love serving it with a good cup of strong coffee and a side of fresh fruit like sliced strawberries or melon. It’s warm, filling, and requires absolutely no morning fuss. When it comes to Brunch, this is where it truly shines. I’ll plate it up a little more elegantly, perhaps with a dusting of powdered sugar and a scattering of fresh berries right on top. To drink, a mimosa or a sparkling cider feels just right. For those evenings when you’re craving something sweet, it works beautifully as an easy Dessert. Serve it warm with a scoop of vanilla bean ice cream or a drizzle of caramel sauce – it’s pure decadence! And for those ultra-casual, cozy afternoons, it’s perfect as a sweet treat. I’ll sometimes just grab a fork and eat it straight from the dish while I’m curled up on the couch with a good book and a mug of hot chocolate. My family also loves it with a side of crispy bacon; the salty crunch is the perfect counterpoint to the sweet, soft casserole. Another favorite combination is with a simple fruit salad – it’s a balanced and delightful meal.
Top Tips for Perfecting Your Overnight French Toast Casserole
I’ve made this Overnight French Toast Casserole more times than I can count, and over the years, I’ve picked up a few tricks that really elevate it from good to absolutely spectacular. When it comes to the bread, Zucchini Prep isn’t really applicable here, but for bread, make sure it’s on the slightly drier side – day-old bread is your best friend. If your bread is super fresh, you can even lightly toast it before cubing and soaking. This helps it absorb the custard without becoming mushy. For the soaking itself, Mixing Advice is key. Don’t overmix once the custard is added to the bread; you want to coat it, not mash it. A gentle fold with a spatula is perfect. You want to ensure all the bread pieces are submerged in the custard mixture before you transfer it to the baking dish. For Swirl Customization, if you’re adding jam or Nutella, a little goes a long way. Just dollop it on top and use a skewer to make gentle swirls. Over-swirling will make it muddy rather than distinct. If you’re using fruit, don’t thaw frozen berries completely; a little frost will help prevent them from making the casserole too watery. For Ingredient Swaps, I’ve found that whole milk or half-and-half create the creamiest results for the custard. You can use skim milk or even some plant-based milks, but the texture might be slightly less rich. For sweetness, brown sugar in the filling provides a lovely caramel note; granulated sugar works too, but it’s not quite the same. When it comes to Baking Tips, trust your oven, but keep an eye on it. If the top starts browning too quickly, tent it loosely with foil. I usually bake mine on the middle rack for even cooking. A toothpick or knife inserted into the center should come out clean, indicating the custard is set. For Glaze Variations, remember that consistency is key. Start with less liquid and add more gradually until you get that perfect drizzling consistency. If it gets too thin, whisk in a little more powdered sugar. If it’s too thick, add a tiny bit more milk or cream. A touch of lemon zest in the glaze can also add a lovely brightness!
Storing and Reheating Tips
The beauty of this Overnight French Toast Casserole is that it’s already made ahead, but what if you have leftovers or want to prepare it even further in advance? Storing and reheating are super simple. If you have any leftovers, you can store them at Room Temperature for no more than 2 hours. After that, it’s best to refrigerate it. For Refrigerator Storage, once cooled, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. It will stay good in the fridge for up to 3-4 days. The texture remains remarkably good, though it might not be quite as puffy as when it’s fresh. If you want to keep it for longer, Freezer Instructions are your best bet. Let the casserole cool completely, then wrap the entire dish tightly in a couple of layers of plastic wrap and then a layer of aluminum foil. Alternatively, you can cut it into individual portions, wrap each piece tightly in plastic wrap, and then place them in a freezer-safe bag or container. It can be stored in the freezer for up to 2-3 months. To thaw, transfer frozen portions to the refrigerator overnight. For Glaze Timing Advice, I always recommend making the glaze fresh right before serving. If you’ve stored leftovers in the fridge, it’s best to reheat the casserole first and then drizzle with a freshly made glaze. If you’re freezing, definitely hold off on the glaze until after reheating.
