Ingredients

Casserole:

1 loaf French bread challah, or French country bread
8 large eggs
1 1/2 cups whole milk
1 cup heavy cream
1/2 cup brown sugar packed
1 tablespoon vanilla extract
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1 cup berries optional; can be fresh or frozen, in small pieces

Topping:

1/2 cup brown sugar packed
1/2 cup salted butter softened
2 tablespoons all-purpose flour spooned and leveled
1 teaspoon ground cinnamon

Optional toppings:

Fresh fruit
Maple syrup
Powdered sugar

Instructions

Preheat the oven to 350° Fahrenheit.
Spray a 9x13 inch baking pan with nonstick spray. Slice and cube the bread into 1-inch pieces. Spread the bread in the prepared baking dish and set aside.
In a bowl, whisk together the eggs, milk, heavy cream, brown sugar, vanilla, cinnamon, and nutmeg until smooth, ensuring no lumps remain. Pour this mixture over the bread, ensuring all pieces are well saturated.
For the topping, mix the brown sugar, softened butter, flour, and cinnamon in a separate bowl until well combined. The texture should resemble wet sand.
If using, add the desired fruit (e.g., blueberries, raspberries, or sliced strawberries) by pushing them into the casserole. Then, sprinkle the prepared topping evenly over it.
Bake in the preheated oven for 45-55 minutes, or until the top is golden brown.
Once the casserole is golden brown and set, remove it from the oven. Let it rest for a few minutes to firm up slightly. Then, serve hot, garnished with your choice of toppings like syrup, fresh fruit, or a sprinkle of powdered sugar.
