This overnight pumpkin spice french toast bake is a make-ahead breakfast casserole that combines day-old brioche with a creamy pumpkin custard and a crunchy streusel topping. Perfect for fall mornings, it’s assembled the night before and baked fresh in the morning for a stress-free, crowd-pleasing meal.
For best results, use day-old bread. If bread is fresh, cube and let sit out for an hour or bake at 300°F for 10 minutes. The overnight soak is crucial for texture. Let the bake rest for 10 minutes after baking to allow custard to set. For a dairy-free version, use full-fat oat milk and coconut cream. For gluten-free, use gluten-free brioche and 1:1 gluten-free flour blend for streusel.
