Common Mistakes to Avoid When Making a Lemon Berry Croissant Casserole
Even the best recipes can go sideways with a few slip-ups. Avoid these pitfalls for perfect results every time:

- Using fresh croissants: Day-old croissants hold up better in the custard, keeping the texture just right.
- Overbaking: Keep an eye on the casserole after removing the foil. You’re looking for a golden top and set custard—no dry edges here!

- Perfect Pairing: Complement the flavors with a refreshing mimosa or a chilled glass of iced coffee.

Healthier Alternatives
Trying to keep things on the lighter side? Here are some easy swaps without sacrificing flavor:
- Heavy Cream Swap: Use almond milk or Greek yogurt for a lighter custard.
