16 oz French bread, cut into 1‑inch cubes

1 tbsp granulated sugar
3/4 tsp ground cinnamon
5 cups frozen berries (raspberry, blackberry, blueberry blend)

Pour the berry mixture into the prepared baking dish.
Spoon the soaked bread cubes over the berries.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 3‑4 days. To reheat, warm individual portions in the microwave for 30‑60 seconds or until heated through, or place the casserole in a preheated 350°F (175°C) oven for about 15‑20 minutes until warmed. For best texture, avoid overheating which can dry out the bread.
