Grease a 9x13 inch casserole dish with butter or oil. Place cubed dry French bread into the dish, filling about 3/4 of its capacity.
02 -
In a large mixing bowl, whisk together eggs, milk, vanilla extract, cinnamon powder, and brown sugar until well combined.
03 -
Pour the egg mixture evenly over the bread cubes, ensuring all pieces are well coated. Add sliced strawberries and blueberries on top.
04 -
Cover the casserole dish with plastic wrap and refrigerate for at least 4 hours or preferably overnight to allow the bread to soak.
05 -
Preheat oven to 350°F (175°C). Bake the casserole uncovered for 35-50 minutes, checking for doneness at the 35-minute mark. Bake longer if necessary.

Sprinkle powdered sugar over the casserole if desired, drizzle with maple syrup, and serve warm. Pair with bacon slices for a hearty brunch.
