Notes
Day-old bread works best — slightly stale bread absorbs custard better without turning mushy. Don't oversoak thin bread; adjust timing by thickness. Keep cooked slices warm in a 100°C oven while finishing the batch. To make dairy-free, substitute almond or oat milk for whole milk and use coconut oil instead of butter.
Cooked French toast keeps in the refrigerator for up to 3 days. Reheat in a toaster or oven at 180°C for 5 minutes. Freeze in a single layer then transfer to a freezer bag for up to 3 months.
