A quick and easy French toast casserole that you prepare the night before and bake in the morning, perfect for busy mornings. It features a custardy texture with crispy edges and uses simple pantry staples.
Do not skip the overnight soak to ensure custardy softness without sogginess. If the top browns too quickly, tent loosely with foil halfway through baking. Let casserole come to room temperature before baking for even cooking. Use brioche or challah for best texture. For gluten-free, use sturdy gluten-free bread. For dairy-free or vegan, substitute milk and butter with plant-based alternatives and eggs with flax eggs.
