Make this easy croissant French toast casserole for your next brunch! Buttery croissants soaked in creamy custard with berries, baked golden and served with maple syrup. Wonderful for making ahead!
Cut the croissants into 1-1.5 - inch pieces. Place them in the baking dish.
In a bowl, combine the milk, eggs, sugar, vanilla extract, cinnamon powder, and salt.
Whisk well and pour over the croissants. Press the bread down gently so it soaks the custard well.
Add the berries on top and tuck them in between the croissant layers.
Cover and keep aside for at least an hour.You can refrigerate the casserole at this point overnight as well. If keeping it overnight, add the berries before baking.
When you're ready to bake, preheat the oven to 180 C/ 350 F.
Sprinkle sugar on top of the casserole and bake at 180 C/ 350 F for 40-45 minutes, until the top is golden and puffy and the custard is set.
Let the casserole cool for 10-15 minutes before serving. Sprinkle some powdered sugar if you wish and serve warm with maple syrup or honey. Enjoy!

Notes
Use room temperature ingredients for the custard and whisk them well. This helps get a homogeneous mixture.
Don't skip the soaking time. The longer the croissants sit in the custard, the better the texture. Overnight is great, but even 1 hour will make a big difference.
Fresh croissants work well, but for the best texture, use day-old or stale croissants.
If your casserole is browning too fast, tent the dish with aluminum foil.
Thaw and drain frozen berries before adding them to the French toast croissant casserole.
If you're making an overnight casserole, add the berries in the morning, before baking.
