{Overnight} Brioche French Toast Casserole

This overnight Brioche French Toast Casserole is a wonderful dish for holidays or anytime throughout the year. Preparing it the night before makes breakfast or brunch the next morning so easy!

As I was standing at the counter, grazing on this French Toast Casserole right out of the pan, my husband walked over. And instead of knocking some sense into me…he pulled out another fork and joined me. #enabler.

This is a great recipe for the holidays or Mother’s Day breakfast, which is easily prepped the night before, so in the morning you can focus on unwrapping gifts. And hugging. And crying.

Brioche French Toast Recipe

Here’s a brief rundown of what you’ll need:

Bread – this recipe calls for Brioche, which is a rich butter and egg bread with a beautiful brown crust.
Custard – eggs, whole milk, vanilla, salt, and nutmeg.
Caramel layer – brown sugar, butter, corn syrup, and amaretto liquor.
Fruit topping – blackberries and sugar.

How to Make French Toast Casserole

This casserole is so easy to make! Here’s a summary (scroll down for the detailed printable recipe card.)

1. First make the caramel-like sauce by boiling the sugar, butter, corn syrup, and amaretto together in a saucepan, then pour the mixture into a greased 9×13 casserole dish in an even layer to coat the bottom.
2. Slice the brioche bread and place on top of the sauce in a flat, even layer.
3. Whisk together the ingredients for the custard and slowly pour it over the bread, making sure it’s all evenly coated.
4. Let it soak for at least 4 hours, preferably overnight.
5. Lightly crush the blackberries and sugar together with a fork; let stand until a syrup forms.
6. Bake the casserole until a knife inserted near the center comes out clean and the top is lightly brown.
7. Let stand for about 15 minutes, then invert portions onto plates and serve with the sweetened berries – delicious!

Recipe Notes

• Challah or another sweet egg bread can replace the Brioche, if you can’t find it.
• The amaretto can be swapped out for an equal amount of Frangelico, Creme de Cacao, or Kahlua. They will all lend a completely different flavor, but equally good.
• There isn’t a proper non-alcoholic substitute for amaretto, since this recipe calls for 1/4 cup and almond extract would be far too potent.

Storing Leftovers

Allow the casserole to cool completely, then store the bread and fruit topping separately, in airtight containers in the refrigerator up to 2 days.

Can I freeze French toast casserole? Yep! I usually cut any cooled leftovers into individual portions, so I can just grab and defrost what I need. Leftovers will keep in the freezer for up to 1 month properly stored. Wrap in plastic wrap, cover with foil, and freeze. Thaw in the fridge overnight, remove the plastic wrap and foil before heating up. I recommend freezing the casserole without the fruit topping and simply making that before serving.
