- Bake the French Toast Casserole:
- Preheat your oven to 350°F (175°C).
- Remove the French toast casserole from the refrigerator and let it sit at room temperature for about 15 minutes while the oven preheats.
- Sprinkle the streusel topping evenly over the top of the casserole.
- Bake for 45-55 minutes, or until the casserole is puffed up, golden brown, and set in the center. A knife inserted into the center should come out clean.
- If the top starts to brown too quickly, you can loosely cover the casserole with aluminum foil.
- Serving:
- Let the baked French toast casserole cool for a few minutes before serving.
- Cut into squares and serve warm, with maple syrup, powdered sugar, fresh berries, or whipped cream, if desired.
Tips:
- Bread Choice: For the best texture, use a day-old bread that’s slightly dry. Brioche or challah will give you a rich and tender casserole, while French bread will provide a firmer texture.
- Custard Soaking: Allowing the bread to soak in the custard mixture for several hours or overnight is key to a moist and flavorful casserole.
- Customizations: Feel free to add your favorite mix-ins to the casserole, such as chocolate chips, blueberries, or diced apples, before baking.
- Make-Ahead: This casserole is a great make-ahead breakfast option. You can prepare it the night before and bake it in the morning for a stress-free and delicious breakfast.
