French Toast Casserole — The Easy Make-Ahead Breakfast for a Crowd
The Make-Ahead Breakfast That Works for Every Kind of Morning
French Toast Casserole is one of those recipes I keep on repeat — it works for a slow family weekend morning, it absolutely shines as breakfast for dinner on a busy weeknight, and it shows up the day I need to feed a crowd without losing my mind. You make it the night before, tuck it in the fridge, and all you have to do is pop it in the oven when you’re ready. It comes out crispy on the outside, soft and custardy on the inside, drizzled with syrup and dusted with powdered sugar. My 14-year-old called this one top tier, which is high praise from a teenager. And when it was Teacher Appreciation Week at my kids’ school and I needed to feed thirty teachers without being up at 4 AM, this French Toast Casserole is what I made — two pans of it, gone by the end of breakfast. It is the easiest make-ahead breakfast for a crowd I know.
🥘 This one’s in my collection of casseroles for a crowd — the ones I actually make when I’m feeding a houseful, gathered in one place.

- Cut brioche bread into 1-inch chunks and layer evenly in the bottom of a 9×13 pan or disposable aluminum foil pan.
- In a large mixing bowl, combine eggs, half and half, heavy cream, sugar, cinnamon, vanilla, and salt. Whisk together until well blended.
- Pour the custard mixture evenly over the brioche chunks. Gently press the bread down into the mixture to make sure every piece is soaked.
- Drizzle the melted butter evenly over the top. This is what gives you the slightly crispy tops!
- Cover with foil and refrigerate overnight (or at least 1 hour if you’re short on time).
- When ready to bake, remove from the fridge and bake UNCOVERED at 375°F for 30–35 minutes, until golden and set.
- Remove from oven and immediately sprinkle powdered sugar generously over the top. Drizzle pancake syrup evenly across as well.

Notes
Four Weeks of Family-Friendly FoodWhen people gather, I cook. Four weeks of the dinners my crowd asks for — planned, tested, and shopped for. Come see what’s in the cookbook →Why This French Toast Casserole Works
I have only been making this French Toast Casserole for several months, but it has quickly moved into the top of my favorites. The first time I brought it somewhere, I spent about five minutes explaining that yes, you make it the night before, and yes, that is really all there is to it. People cannot believe how simple it is until they see how beautiful it comes out of the oven.
The secret is the brioche bread . Regular sandwich bread just doesn’t have the same structure — brioche soaks up that rich custard without falling apart, and the thick slices mean you get chunks that are soft and custardy in the middle with a little bit of caramelized crunch on the outside edges. It is the best of both worlds.
And the butter drizzle the night before? That is not optional. I know it seems like a lot, but six tablespoons of melted butter over the top is what gives you those gorgeous golden crispy bits on the top pieces. It is what takes this from good to absolutely spectacular.
A Few Things That Make French Toast Casserole Even Easier
- Use a disposable aluminum foil pan if you are taking it somewhere. No pan to carry back home, no awkward “I’ll get that to you next week” moments. Just leave it and let them keep it.
- Make it the night before — really. This is the entire point of the recipe. The bread needs time to fully soak up the custard so you get that signature soft, custardy middle. An hour in the fridge will do in a pinch, but overnight is the magic.
- Do not skip the butter drizzle. Six tablespoons of melted butter over the top before it goes in the fridge is what gives you those golden, crispy edges on the top pieces when it is baked. It looks like a lot. Trust the recipe.
- Cut the brioche in big chunks, not slices. One-inch cubes give you more surface area for the crispy bits and a better custard-to-bread ratio in every bite. Slabs of bread don’t soak as evenly.
- Finish with powdered sugar at the table, not in the kitchen. A shaker sifter right before serving keeps the sugar from melting into the warm casserole. It is the difference between “home cooked” and “this looks like a restaurant.”
French Toast Casserole FAQ — The Questions I Get Every Time
What temperature and how long do I bake French Toast Casserole?
Bake at 350°F for 45 to 55 minutes, uncovered, after pulling the pan straight from the fridge. You want the top to be deeply golden and the center to be set but still soft — a knife inserted in the middle should come out clean of liquid custard. If the top is browning faster than the middle is setting, tent it loosely with foil for the last 10 minutes.
Can I make French Toast Casserole in a regular 9×13 pan?
Absolutely. I used a disposable aluminum foil pan because I was bringing it to school and didn’t want to worry about getting my pan back. At home I always reach for my deep Pyrex 9x13 — the extra depth gives the bread room to soak up every last drop of custard without spilling over. Any regular Pyrex or ceramic 9×13 baking dish works perfectly. Use whatever pan you have — same bake time, same beautiful result.
Do I have to make French Toast Casserole the night before?
I always make this overnight and that is my strong recommendation — the bread needs time to really absorb all that custard. If you are in a pinch, at least one hour in the fridge will get you there, but overnight is truly when the magic happens. The bread fully transforms into something that is almost like bread pudding in the best possible way.
Can I freeze French Toast Casserole?
Yes — assemble the entire pan unbaked, cover tightly with foil plus plastic wrap, and freeze up to two months. Thaw overnight in the fridge before baking. Add about 10 extra minutes to the bake time when going from cold-from-fridge versus room temperature. Already-baked leftovers also reheat well in a 325°F oven for about 15 minutes covered with foil.
Can I use a different bread for French Toast Casserole?
Brioche is my strong preference, but challah, French bread, or Texas toast all work — anything that is enriched and sturdy enough to hold up to soaking. Avoid regular sandwich bread, which falls apart and turns mushy. If your bread is fresh and soft, leave the cubes out on the counter for a few hours or overnight to dry out a bit. Slightly stale bread soaks up custard better than fresh.
What do you serve with French Toast Casserole?
Honestly? Nothing. This is the whole breakfast. Maybe some fresh fruit on the side if you want to feel balanced about it, but the casserole is rich and filling enough to stand completely on its own. If you’re putting together a full brunch spread, bacon or breakfast sausage and a fruit salad round it out beautifully — but most mornings, this is the entire meal.
How do I scale French Toast Casserole for a bigger crowd?
One 9×13 pan feeds 10 to 12 people comfortably as part of a breakfast spread, or 8 if it’s the main event. For more than that, make two pans rather than trying to scale into a bigger dish — the custard needs even contact with the bread to set properly, and a deeper pan will leave you with raw middles and burnt tops. Two pans of this is what fed all 30 teachers at Teacher Appreciation Week.
