Easy French Toast Casserole (Overnight) Recipe FAQs
Can I use a different type of bread for this casserole?
Absolutely! While French bread provides a lovely texture and flavor, you can use challah, brioche, or even whole grain bread. Just ensure it’s sturdy enough to soak up the egg mixture without falling apart.
How do I store leftovers of the French toast casserole?
After letting the casserole cool completely, cover it tightly with plastic wrap or aluminum foil and store it in the refrigerator. It will stay fresh for up to 3 days. Simply reheat in the oven at 350°F (175°C) for about 15-20 minutes until warmed through.
Can I make this recipe dairy-free?
Yes, you can substitute the milk and heavy cream with almond milk or oat milk and use a plant-based butter instead of regular butter. The eggs cannot be replaced if you’re looking for a traditional French toast flavor and texture, but you can explore flaxseed or chia seed substitutes if needed.
What should I do if my casserole is soggy after baking?
If your casserole turns out soggy, it may have been soaked too long or had too much liquid added. For next time, reduce the soaking time to about 8 hours rather than overnight or ensure you’re using slightly stale bread which can absorb more liquid without becoming mushy.
