This recipe creates a delightful Cinnamon Baked French Toast casserole, perfect for a crowd. It features chunks of bread soaked overnight in a rich egg custard, topped with a buttery cinnamon-brown sugar streusel, then baked until golden. Serve warm with syrup and fresh blueberries for a comforting breakfast or brunch.
Optimal results come from allowing the bread to soak in the custard overnight; this ensures maximum absorption and a custardy texture. For the streusel, ensure the butter is very cold to achieve a crumbly, pebble-like consistency, which melts slowly and creates a delicious crisp topping. Adjust baking time based on desired texture: longer for a firmer, crispier exterior, or shorter for a softer, bread-pudding like interior. Serve immediately with warm syrup and fresh fruit for best enjoyment.
