Common Mistakes to Avoid
Many people struggle when making an Overnight Blueberry French Toast Casserole. Here are some common mistakes to watch out for.
- Skipping the cream cheese step: Not properly mixing the cream cheese can lead to lumps in your casserole. Make sure to blend it well with powdered sugar and milk until smooth.
- Using stale bread: Fresh bread absorbs the custard better. Avoid using stale bread as it may not soak up the flavors effectively.
- Not letting it rest overnight: Skipping the overnight refrigeration can result in a less flavorful dish. Allowing it to sit helps all the ingredients meld together.
