Understanding French Toast Casserole
What is a French Toast Casserole?
Unlike traditional French toast that requires dipping and flipping each slice individually, a French toast casserole is a baked dish where bread cubes soak up a rich, custard-like mixture before being baked to golden perfection. It’s a low-effort, high-reward dish—perfect for holidays, brunch gatherings, or lazy weekend mornings.
Why is it a Great Make-Ahead Breakfast?
One of the best things about French toast casserole is its overnight preparation. By assembling it the night before, the flavors have time to blend, and the bread fully absorbs the custard mixture, resulting in a deeper, richer taste. Plus, all you need to do in the morning is pop it in the oven—no extra effort required!
Brioche vs. Croissant: Which One is Better?
Both brioche and croissants are excellent choices, but they offer slightly different textures and flavors:
🥖 Brioche French Toast Casserole → Soft, fluffy, slightly sweet, absorbs custard beautifully.
🥐 Croissant French Toast Casserole → Buttery, flaky, with a richer taste and crispier edges.
If you prefer a more traditional, fluffy texture, brioche is your best bet. If you want something indulgent and extra buttery, croissants are the way to go!
More Details & Insights
Brioche vs. Croissant: Which One is Better for French Toast Casserole?
When making a French toast casserole, choosing the right bread is crucial. Both brioche and croissants work wonderfully, but they create slightly different results:
- Brioche French toast casserole is soft and pillowy with a slightly sweet taste. The rich, buttery texture of brioche soaks up the custard perfectly without becoming too soggy.
- Croissant French toast casserole is flaky and indulgent. Since croissants have a more airy structure, they create a crispier, golden-brown top while staying soft inside.
If you’re looking for a classic, soft, and custardy casserole, brioche is the best choice. However, if you want a bakery-style brunch with a crispy, buttery finish, croissants will take your dish to the next level.

Best Bread Options for French Toast Casserole
While brioche and croissants are the top contenders, other bread options work well too:
✔ Challah – Slightly eggy and rich, similar to brioche.
✔ French bread – Gives a firmer, slightly chewy texture.
✔ Sourdough – Adds a slight tanginess and holds up well to the custard.
For the best texture, use day-old or slightly stale bread. Fresh bread absorbs too much liquid and can result in a mushy casserole.
How to Make It Overnight for a Stress-Free Morning
One of the biggest perks of French toast casserole is that you can prepare it ahead of time! Here’s how:
1️⃣ Assemble the casserole the night before by layering bread cubes and pouring the custard mixture over them.
2️⃣ Cover the dish with plastic wrap and refrigerate overnight. This allows the bread to fully absorb the custard, enhancing both texture and flavor.
3️⃣ The next morning, remove it from the fridge, let it sit at room temperature for 15–20 minutes, and then bake as usual.
This overnight method is perfect for busy mornings, holidays, and brunch gatherings. Just bake, serve, and enjoy!
