  • Baking dish 8x12 inches/ 20x30 cm


  • 14 oz chocolate chip brioche 400 g, Notes 1, 2
  • 1 teaspoon butter
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup whole milk 230 ml
  • 1 cup heavy cream 230 ml
  • 5 tablespoons granulated sugar divided
  • 4 ½ oz raspberries 125 g, Note 3
  • 4 ½ oz blueberries 125 g
  • ¼ cup pecans chopped 40 g


  • Butter the baking dish well (bottom and sides).
    1 teaspoon butter
  • Cut the brioche into thick slices, then cut the slices into large cubes. Arrange them in the baking dish.
    14 oz/ 400 g brioche
  • Whisk the eggs with vanilla extract, milk, heavy cream, and some of the sugar.
    3 eggs + 1 cup (250 ml) whole milk + 1 cup (250 ml) heavy cream + 4 tablespoon sugar
  • Soak bread: Pour the egg mixture over the brioches pieces. Cover the dish with plastic wrap and refrigerate it for at least 2 hours. You can refrigerate it overnight as well.
  • Preheat the oven to 350°F/ 175°C. Remove the casserole from the fridge and let it stand at room temperature until the oven preheats.
  • Scatter ⅔ of the raspberries and blueberries over the soaked brioche pieces. Fold them in lightly using a spoon or a spatula.
    4 ½ oz (125 g) raspberries + 4 ½ oz (125 g) blueberries
  • Scatter the remaining berries and the chopped pecans on top of the casserole. Sprinkle lightly with the remaining sugar.
    ¼ cup (40 g) pecans + 1 tablespoon sugar
  • Bake in the preheated oven for 40-45 minutes or until set and golden. If it’s still too jiggly in the middle, bake it for 5 more minutes, then check again (a very light jiggle is ok, the brioche casserole will set more while it stands).
  • Rest casserole: Remove from the oven and let set for about 15 minutes before serving.


  1. Bread: Small individual brioches or a brioche loaf. Substitute brioche with challah bread.
  2. Chocolate: If you have plain brioche but would still like the chocolate chips, add about 1 cup of chocolate chip to the dish together with the berries.
  3. If some of the raspberries are very large, cut them in halves.
