Blueberry Mascarpone French Toast Bake is a rich and custardy breakfast casserole layered with soft bread, creamy mascarpone, and juicy blueberries. Baked until golden, it’s the perfect dish for brunch, holidays, or cozy mornings.

Ingredients

  • 1 loaf brioche or challah bread (day-old), cubed
  • 6 large eggs
  • 2 cups milk or half-and-half
  • 1/2 cup mascarpone cheese
  • 1/3 cup sugar
  • 1 tsp vanilla extract
  • 1 tsp lemon zest (optional)
  • 1 1/2 cups fresh or frozen blueberries
  • Butter, for greasing
  • Powdered sugar or maple syrup, for serving

Instructions

  1. Grease a 9×13-inch baking dish with butter. Spread half the bread cubes in the dish.
  2. Dot spoonfuls of mascarpone over the bread and scatter half of the blueberries on top.
  3. Add the remaining bread and top with the rest of the blueberries.
  4. In a large bowl, whisk together eggs, milk, sugar, vanilla, and lemon zest (if using).
  5. Pour the custard evenly over the bread. Press down gently so the bread soaks up the mixture.
  6. Cover and refrigerate for at least 2 hours, or overnight for best results.
  7. Preheat oven to 350°F (175°C). Bake uncovered for 45–55 minutes, until golden and the center is set.
  8. Cool slightly before dusting with powdered sugar or serving with maple syrup.

Notes

  • Use cream cheese instead of mascarpone for a tangier version.
  • Try other berries like raspberries or blackberries.
  • Add chopped nuts for crunch before baking.
  • Top with lemon glaze or berry compote for a dessert-like finish.
