Variations

You can swap blueberries with raspberries, strawberries, or a mixed berry blend for a different flavor. Adding chopped nuts like pecans or walnuts gives a nice crunch. For a richer taste, use brioche or challah bread instead of standard french bread. A drizzle of maple syrup or a dusting of powdered sugar before serving adds extra sweetness.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave for about 1–2 minutes or place the dish in the oven at 160°C (325°F) until heated through. Covering with foil helps prevent drying out.

FAQs

Can I make this without overnight chilling?

Can I use frozen blueberries?

Yes, just add them frozen without thawing to avoid excess moisture.

What type of bread works best?

French bread, brioche, or challah all work well due to their structure and ability to absorb liquid.

Can I reduce the sweetness?

You can lower the powdered sugar or skip extra toppings like syrup.

How do I know when it’s done baking?

The center should be set and no longer jiggly, and the top should be golden.

Can I make this dairy-free?

Yes, substitute dairy-free cream cheese and milk alternatives.

Can I freeze this casserole?
