Breakfast is the most important meal of the day, but standing over a griddle flipping individual slices of bread is nobody’s favorite morning activity. This Sweet Easy Baked French Toast Casserole Breakfast solves that problem beautifully. It takes the classic flavors of French toast—cinnamon, vanilla, and custard-soaked bread—and bakes them into a warm, sliceable casserole. Topped with a crunchy brown sugar streusel, this dish is decadent enough for Christmas morning yet simple enough for a lazy Sunday brunch.

Ingredient Highlights & Substitutions
Essential Ingredients
- Bread: Brioche, Challah, or French bread are ideal. They have the structure to hold the liquid. Sourdough offers a nice tang if you prefer less sweet.
- Eggs & Milk: The base of the custard. Whole milk or Half & Half yields the richest texture.
- Cinnamon & Nutmeg: The classic warming spices that give French toast its signature aroma.
- Brown Sugar: Used in the topping to create a caramelized, crunchy crust.
- Butter: Cold butter cut into the topping is what makes the streusel crisp.
Smart Substitutions
- Dairy-Free: Almond milk works well, though the custard will be slightly less creamy.
- Flavor Twists: Add orange zest to the custard for a citrus pop, or toss a handful of blueberries in with the bread.
- Syrup: A simple dusting of powdered sugar is often enough due to the sweet topping, but maple syrup is classic.
Step-by-Step Instructions
Prep Phase
Grease a 9×13 baking dish. Cut your bread into 1-inch cubes. If your bread is fresh, toast the cubes in the oven for 10 minutes to dry them out.
Cooking Phase
Place the bread cubes in the prepared dish. In a large bowl, whisk together eggs, milk, sugar, vanilla, and spices. Pour this custard evenly over the bread, pressing down slightly to ensure every piece is soaked. Optional: Let it sit for 20 minutes (or overnight) to absorb. For the topping, mix flour, brown sugar, cinnamon, and cold cubed butter until it looks like wet sand. Sprinkle over the casserole. Bake at 350°F for 35-45 minutes until the top is golden and the center is set.
Pro Tips for Perfect Results
Technique Secrets
The “Soak Time” is variable but important. If using very dry French bread, you can let it soak overnight in the fridge. If using softer Brioche, a 30-minute soak on the counter is plenty. Over-soaking soft bread can lead to a mushy bottom layer.
Common Mistakes to Avoid
- Using Sandwich Bread: Standard white sandwich bread is too thin and soft; it will dissolve into the egg mixture. Stick to bakery loaves.
- Undercooking: The top will brown before the center is cooked. If the top gets too dark, cover it loosely with foil for the last 15 minutes.
Serving Ideas & Pairings
Presentation & Plating
Dust the warm casserole with powdered sugar just before serving. Slice into squares and serve with a pitcher of warm maple syrup.
Pairing Suggestions
- Protein: Serve with crispy bacon or sausage links to balance the sweetness with salt.
- Savory Option: If you prefer a savorier start to your morning, consider making The Ultimate Overnight Slow Cooker Breakfast Dish instead, which is packed with eggs, sausage, and hash browns.
Frequently Asked Questions
Q1? Can I make this ahead of time?
Yes, this is an excellent “Overnight” recipe. Assemble it, cover, and refrigerate. Just add the crumb topping right before baking so it doesn’t get soggy.
Q2? Why is my casserole soggy?
Either the bread was too fresh, or the ratio of milk to eggs was too high. Ensure you toast your bread cubes if they feel soft.
Q3? Can I reheat leftovers?
Yes, it reheats well in the microwave, but for the best texture (to recrisp the topping), reheat individual slices in a toaster oven.
