This easy, make-ahead Berry French Toast Casserole is a crowd-pleasing brunch favorite featuring tender brioche, a creamy vanilla custard, and bursts of juicy berries. Perfect for lazy weekends, holidays, or any time you want a comforting, stress-free breakfast.
Day-old bread works best for absorbing the custard. Overnight soaking ensures a tender texture. Mix fresh and frozen berries for best flavor and texture. Turbinado sugar adds a crunchy topping. For gluten-free or dairy-free, use appropriate bread and milk/cream substitutes. Leftovers keep well and can be reheated or frozen.
