Ingredients

Unsalted butter, room temperature, for baking dish

3 ounces bittersweet chocolate, coarsely chopped

7 ounces brioche, cut into eight 1/2-inch slices, halved diagonally

1 1/2 pounds firm but ripe pears, such as Anjou or Bartlett (about 3), cored and very thinly sliced

3 large eggs, plus 3 large egg yolks

1 1/2 cups whole milk

1 1/4 cups heavy cream

1/2 cup packed light-brown sugar

1 teaspoon ground cinnamon

1/4 teaspoon fine salt

1 tablespoon sanding or other coarse sugar

Preparation

Preheat oven to 325 degrees. Butter a shallow 2-quart baking dish and sprinkle bottom evenly with chocolate. Arrange brioche in dish, alternating each slice with 3 or 4 pear slices.

In a large bowl, gently whisk together eggs and egg yolks, milk, cream, brown sugar, cinnamon, and salt. Pour mixture evenly over bread and pears and let sit 5 minutes. Sprinkle with sanding sugar.

Bake until brioche is puffed and custard is just set, 50 to 60 minutes. Let cool slightly. Serve warm or at room temperature.
