Description

A cozy bake that combines soft, sweet bread with bursts of warm blueberries in a cinnamon-vanilla custard, perfect for feeding a crowd or enjoying on a leisurely weekend morning.


Ingredients

Scale
  • 8 cups day-old bread, torn into 1-inch pieces (challah, brioche, or sturdy white)
  • 2 cups fresh or frozen blueberries (if frozen, no need to thaw)
  • 4 large eggs
  • 2 cups whole milk (or 1 cup milk + 1 cup cream for richer texture)
  • 1/3 cup granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • 2 tablespoons unsalted butter, melted
  • 1/4 cup brown sugar (light or dark)
  • Optional: 1/2 teaspoon lemon zest for brightness
  • Powdered sugar, maple syrup, or whipped cream for serving

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
  2. Place the torn bread in the baking dish and sprinkle blueberries evenly over the top. Gently press berries into the bread.
  3. Whisk together eggs, milk, sugar, vanilla, cinnamon, and a pinch of salt until smooth.
  4. Pour the custard over the bread and berries. Let sit for 10–15 minutes, or cover and refrigerate overnight.
  5. Mix melted butter with brown sugar (and lemon zest if using) and sprinkle over the top of the casserole.
  6. Bake uncovered for 40–45 minutes, until the top is golden and the center feels set.
  7. Let the casserole rest for 10 minutes before slicing. Serve warm with powdered sugar, maple syrup, or whipped cream.

Notes

Use unsalted butter for better salt control. Day-old bread is preferred for soaking the custard without falling apart.
