Overnight Stuffed Croissant French Toast Casserole
A decadent breakfast casserole that transforms buttery croissants into an elegant French toast bake. Each croissant is stuffed with sweetened cream cheese and fresh strawberries, then arranged in a custard base with blueberries scattered throughout. The overnight rest allows the custard to fully absorb, creating a rich, custardy interior with golden, toasted edges. Perfect for holiday mornings, brunch gatherings, or special occasions when you want to serve something impressive without morning stress. The combination of cream cheese filling and maple custard makes this version particularly indulgent compared to standard French toast casseroles.

Tips
Use day-old croissants for better absorption and easier slicing without tearing the delicate pastry.
Don't skip the overnight rest - it allows the custard to fully penetrate the croissants for the best texture.
Cover with foil during baking to prevent over-browning, then remove for the last few minutes if desired.
Good to Know
Refrigerate covered up to 2 days. Reheat individual portions in microwave.
Assemble completely up to 8 hours ahead. Keep refrigerated until ready to bake.
Serve warm with maple syrup, fresh berries, and powdered sugar if desired.
Common Mistakes

FAQ
Can I use frozen berries instead of fresh?
Yes, but don't thaw them first. Add frozen berries directly to prevent excess moisture that could make the casserole soggy.
How long will leftovers keep in the refrigerator?
Covered leftovers will keep for up to 2 days. Reheat individual portions in the microwave for 30-60 seconds until warmed through.
Can I freeze this casserole after baking?
Yes, wrap cooled portions tightly and freeze up to 1 month. Thaw overnight in refrigerator before reheating in oven at 350°F.
