Rich and delicious brioche French toast casserole recipe with chocolate chips and lots of berries. This is the easiest way of making French toast using just one pan.
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.
Notes
Bread: Small individual brioches or a brioche loaf. Substitute brioche with challah bread.
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.
If some of the raspberries are very large, cut them in halves.
