Baked Blueberry Mascarpone French Toast Casserole

A rich breakfast casserole that transforms cubed French bread into an indulgent morning treat.

Tips
Use day-old bread for better absorption of the custard mixture without becoming mushy.
Let the casserole rest for 10-15 minutes after pouring the egg mixture to ensure even soaking.
Cover with foil if the top browns too quickly during baking.
Good to Know
Cover and refrigerate for up to 3 days. Reheat individual portions in microwave or warm oven.
Assemble completely the night before, cover and refrigerate. Add 10-15 minutes to baking time if baking from cold.
Serve warm with additional maple syrup, powdered sugar, or fresh berries.
Common Mistakes
Use stale bread to prevent soggy texture from too much moisture absorption.
Don't skip the resting time to avoid uneven soaking and dry spots.
Substitutions
FAQ
Can I use frozen blueberries?
Yes, use frozen blueberries directly without thawing. They may release slightly more juice during baking.
How long will leftovers keep?
Store covered in refrigerator for up to 3 days. Reheat individual portions in microwave for 30-60 seconds.
Can I make this dairy-free?
Substitute coconut milk for regular milk and use vegan cream cheese instead of mascarpone for similar richness.
