Tips & Variations

- Prepare the casserole the night before and refrigerate for a few hours to enhance the custard soak.
- Swap bananas for berries or sliced apples for a different fruity twist.

FAQs
Can I use fresh croissants or do they need to be stale?
Day-old or slightly stale croissants work best as they soak up the custard without becoming overly mushy. Fresh croissants can be used but may result in a softer texture.
Can I prepare this casserole ahead of time?
Yes, you can assemble the casserole the night before, cover it, and refrigerate it. This allows the croissants to absorb the custard fully. Just add the banana slices right before baking to prevent browning.
