A cozy and fuss-free French toast casserole featuring thick-cut brioche soaked in a creamy custard and fresh mixed berries, perfect for breakfast or brunch.
Do not skip the soaking step to avoid dry edges. Drain very juicy berries to prevent sogginess. Cover casserole with foil during first half of baking to trap steam and set custard, then remove foil to brown the top. For a crispy top, brush melted butter or sprinkle brown sugar before final bake.
