Common Mistakes to Avoid
When making Overnight Baked Banana French Toast Casserole, it’s easy to slip up. Here are some common mistakes to watch out for.
- Wrong Bread Choice: Using bread that is too fresh can lead to a soggy casserole. Opt for slightly stale sourdough or French bread for the best texture.
- Not Mixing Ingredients Thoroughly: Skipping the thorough mixing of the egg and milk mixture can result in uneven flavors. Ensure all ingredients are well combined before pouring them over the bread.
- Skipping the Overnight Chill: Not letting the casserole sit overnight means it won’t absorb the flavors properly. Always refrigerate overnight for optimal taste.
- Overbaking: Baking for too long can dry out your dish. Keep an eye on it, and remove it once it reaches a golden-brown color on top.
- Neglecting Toppings: Forgetting to add streusel topping can make your casserole less appealing. Make sure to crumble it on just before finishing baking for added texture and flavor.
