Expert Tips for Easy Overnight Blueberry French Toast Casserole

Soaking Time Matters: Allow the casserole to soak overnight; this step is crucial for achieving that tender, custardy texture everyone loves.

Rest Before Serving: Let the casserole rest for 10-15 minutes after baking. This helps it set, making it easier to portion without falling apart.

Use Fresh Blueberries: Always opt for fresh blueberries if possible. Frozen berries may introduce excess moisture, resulting in a soggy casserole.
