Looking for an easy make-ahead breakfast or brunch? This oven-baked French toast casserole is warm, custardy, and full of cinnamon and maple flavor. Baked in the oven for golden-brown edges and a soft center, it’s a simple, crowd-pleasing dish that’s perfect for holidays, weekend mornings, or feeding a group.

This version is similar in flavor to slow-cooker French toast casseroles but is baked for a crisp top and a tender interior. It’s a torn-bread style casserole topped with a buttery crumb mixture of flour, sugar, and cinnamon. We often make it for team breakfasts, holiday mornings, or paired with scrambled eggs and breakfast meats.

Main Ingredients:
- 1 cup brown sugar
- 1/2 cup butter
- 2 tablespoons real maple syrup
- 1 loaf bread (day-old or slightly dry works best)
- 8 eggs
- 1 1/2 cups milk
- 1 cup half-and-half
- 3/4 cup granulated sugar
- 2 teaspoons vanilla extract
- 1/2 teaspoon ground cinnamon (optional in custard)
- Pinch of salt
Crumb Topping
- 1/2 cup all-purpose flour

How to Make French Toast Casserole in the Oven
Step 1: Make the brown sugar-maple base
Combine 1 cup brown sugar, 1/2 cup butter, and 2 tablespoons maple syrup in a microwave-safe bowl. Heat in 30-second intervals, stirring until melted and smooth. Pour the mixture into a greased 9×13-inch baking dish.
Step 2: Add the bread
Cube or tear the loaf into pieces and place the bread evenly over the sugar-butter layer. Slightly stale bread soaks the custard best.
Step 3: Make the custard
In a large bowl, whisk together 8 eggs, 1 1/2 cups milk, 1 cup half-and-half, 3/4 cup sugar, 2 teaspoons vanilla, a pinch of salt, and a bit of cinnamon if desired. Beat until smooth.

Step 4: Soak the bread
Pour the custard evenly over the bread, pressing gently so the pieces absorb the liquid. Drizzle any remaining melted butter on top. Cover with foil and refrigerate overnight or at least several hours.
Step 5: Prepare crumb topping
Before baking, combine 1/2 cup flour, 1/2 cup brown sugar, 1 teaspoon cinnamon, 1/4 teaspoon salt, and the cold 1/2 cup butter cut into small pieces. Use a pastry cutter or fork to combine until crumbly, then sprinkle over the soaked bread.

Step 6: Bake
Preheat the oven to 350°F. Cover the dish with foil and bake for 35 minutes. Remove the foil and bake another 15–20 minutes, or until the topping is golden and the center is set.
Step 7: Rest and serve
Let the casserole rest 5–10 minutes before slicing. Serve warm with maple syrup, powdered sugar, fresh fruit, or toasted nuts. It pairs well with bacon, sausage, or scrambled eggs.

Storing and Reheating Tips
- Storing: Keep leftovers covered in the refrigerator for up to 4 days.
- Reheating: Warm individual portions in the microwave for 30–60 seconds or reheat in a 325°F oven for 10–15 minutes until heated through.
- Freezing: After baking and cooling, wrap tightly and freeze up to 2 months. Thaw overnight in the fridge and reheat in the oven.
Variations and Substitutions
- Add fruit: Stir in blueberries, chopped apples, or sliced bananas before baking.
- Add nuts: Top with chopped pecans or walnuts for crunch.
- Dairy-free: Use almond or oat milk and dairy-free butter.
- Gluten-free: Substitute your preferred gluten-free bread.

Frequently Asked Questions
Can I make this ahead?
Yes — assemble the casserole the night before, refrigerate, and bake in the morning.
What bread is best?
Brioche, challah, French bread, or Texas toast are excellent choices because they’re thick and absorb custard well.
