French Toast Casserole (Easy Make-Ahead Breakfast)
There are a handful of recipes that earn a permanent spot in your brunch rotation, and this French toast casserole is one of them. Thick cubes of day-old brioche soak in a rich custard made with eggs, brown sugar, cinnamon, vanilla, and a touch of almond extract. By morning the bread has absorbed every bit of that custard and bakes up golden on top, soft and custardy in the center, and somewhere between French toast and bread pudding in the best possible way.

How to Make French Toast Casserole
This recipe is almost entirely hands-off. Here is how it comes together.
Step 1: Prep the Baking Dish and Bread
Grease a 9×13-inch baking dish generously with nonstick cooking spray or butter. Add the cubed brioche bread in an even layer across the bottom of the dish. Day-old or slightly stale brioche is ideal here. Fresh bread can work but tends to get a little too soft after soaking overnight. If your brioche is fresh, spread the cubes on a baking sheet and let them sit out for an hour or two to dry out slightly before using.
Step 2: Make the Custard
In a large mixing bowl, whisk together the eggs, brown sugar, vanilla extract, almond extract, cinnamon, salt, whole milk, and heavy cream until fully combined and smooth. The custard should be well blended with no streaks of egg visible.
Step 3: Pour and Press
Pour the custard evenly over the bread cubes, making sure every piece gets coated. Use your hands or a spatula to gently press the bread down so every cube is submerged in the custard. Cover the dish tightly with plastic wrap and refrigerate for at least 15 minutes, though overnight is the ideal. The longer the bread soaks, the more deeply flavored and custardy the finished casserole will be.
Step 4: Bake
When you’re ready to bake, preheat the oven to 375°F (190°C). Remove the casserole from the fridge and uncover it. Bake for 35 to 45 minutes until the top is deep golden brown and the center is fully set with no jiggle. If the top starts browning too quickly before the center is set, loosely tent with aluminum foil during the last 10 minutes of baking. The casserole is done when a knife inserted into the center comes out clean.
Step 5: Make the Maple Cinnamon Whipped Cream
While the casserole is in the oven, add the heavy cream, maple syrup, powdered sugar, and cinnamon to a large bowl. Beat with a hand mixer or stand mixer on high speed until soft to medium peaks form, about 5 to 7 minutes. Don’t overbeat or it will turn grainy. The whipped cream can be made up to a few hours ahead and stored covered in the fridge until ready to serve.
Step 6: Rest, Top, and Serve
Remove the casserole from the oven and let it rest for 5 minutes before serving. This rest time helps the custard set so it slices and scoops more cleanly. Top generously with fresh berries, a dusting of powdered sugar, a drizzle of maple syrup, and big spoonfuls of the maple cinnamon whipped cream. Serve warm directly from the baking dish.
Storing and Reheating
Leftover French toast casserole keeps well and reheats beautifully. Store cooled leftovers covered tightly in the baking dish or transferred to an airtight container in the refrigerator for up to 4 days. Store the whipped cream separately in a covered bowl in the fridge for up to 2 days and give it a quick stir or brief re-whip before serving if it has deflated.
To reheat individual portions, microwave on medium power for 60 to 90 seconds until warmed through. For reheating a larger portion, cover the dish loosely with foil and warm in a 325°F oven for 15 to 20 minutes. Add the fresh toppings after reheating rather than before so the berries and whipped cream stay fresh.
Freezing the baked casserole is possible but not ideal since the custard texture can become slightly grainy after thawing. If you want to freeze it, do so before baking. Assemble the casserole through Step 3, cover tightly with plastic wrap and then foil, and freeze for up to 1 month. Thaw overnight in the refrigerator and bake as directed, adding 5 to 10 extra minutes to the bake time since it will be starting cold.
Frequently Asked Questions About French Toast Casserole
Yes. The minimum soak time is 15 minutes, which gives the bread just enough time to absorb the custard before baking. For the best results, at least an hour of soaking is recommended. The overnight soak is ideal because the bread fully saturates with custard all the way through, resulting in a richer, more uniform texture. If you’re short on time, 30 to 60 minutes in the fridge is a solid middle ground.
Brioche is the gold standard for this recipe. It’s rich, buttery, and has a slightly sweet flavor that complements the custard beautifully. Challah is an excellent substitute with a very similar texture and richness. A thick-cut white sandwich bread or Texas toast also works in a pinch. Avoid thin sliced sandwich bread since it becomes too soft and dissolves into the custard rather than holding its shape.
Day-old or slightly stale bread has lost some of its moisture, which means it absorbs the custard more readily and holds its structure better during the overnight soak and baking. Fresh bread tends to become overly soft and can turn mushy in the center. If you only have fresh brioche, spread the cubes on a baking sheet and let them dry in a 300°F oven for 10 to 15 minutes before using.
Yes. The almond extract is optional but adds a subtle warmth and depth that elevates the custard beyond a standard French toast flavor. If you don’t have it or don’t enjoy the flavor, simply leave it out and add an extra half teaspoon of vanilla extract instead. The casserole will still be delicious.
