Like most baked casseroles, this dish stores beautifully:
- Refrigerator: Cool completely, cover tightly, and refrigerate for up to 4 days. Reheat in the oven at 325°F until warmed through, or microwave individual portions.
- Freezer: Wrap baked casserole (or portions) tightly in plastic wrap and foil. Freeze up to 2 months. Thaw overnight in the fridge, then reheat before serving.
- Make-Ahead Tip: Assemble the casserole the night before, refrigerate, and bake in the morning. This overnight soak gives the bread extra flavor and texture.

For best results, always store leftovers in airtight containers to lock in moisture and prevent the casserole from drying out. If you’re planning a brunch party, consider baking two smaller casseroles—enjoy one fresh and freeze the other for an easy future breakfast.
Variations of Blueberry French Toast Casserole
Here are a few tricks that guarantee a perfect casserole every time:
- Use Stale Bread: Slightly dried bread absorbs custard better than fresh.
- Balance Flavors: Blueberries provide tartness—balance with sweet toppings like maple syrup.
- Customize the Custard: Swap whole milk for almond milk or add orange zest for brightness.
- Make It Crunchy: Add chopped pecans, walnuts, or streusel topping for extra texture.
- Go Gourmet: Replace part of the milk with cream cheese for a cheesecake-like richness.
- Bake with Care: Cover with foil if the top browns too quickly.
- Serve Warm: This casserole tastes best straight from the oven.
Another tip? Try soaking the bread for at least 6 hours (or overnight). The longer it rests, the creamier and richer the casserole will taste once baked.
