Overnight Blueberry Baked French Toast

Recipe Author Jessie Sheehan


  • 1 lb. loaf of challah or brioche or other enriched bread (this is a lot of bread - you may not need it all)
  • 3 large eggs
  • 3 yolks
  • 1 Tbsp pure vanilla extract
  • 3/4 cup granulated sugar
  • 1/4 cup light brown sugar
  • 2 1/2 cups whole milk
  • 1 1/2 cup heavy cream
  • 6 Tbsp unsalted butter melted, and cooled
  • 1 1/2 cups blueberries fresh, or frozen
  • Turbinado sugar for sprinkling
  • confectioner's sugar for dusting


  • Grease a 13x9x2-inch pan with cooking spray or softened butter.
  • Slice the challah into 1-inch slices and slice those slices in half. Arrange attractively in your prepared pan, layering the bread in three rows, as in the photographs.
  • Combine the eggs, yolks, and vanilla in a large mixing bowl and whisk. Add the sugars and whisk again. Add the milk, cream, and butter (which may make the custard curdle a little) and whisk a final time. There will be A LOT of custard. Don't be alarmed: the bread will eventually soak it all up (either in the fridge or in the oven) and the extra custard makes for the dreamiest of baked french toasts (IMHO). Pour the custard over the bread, pressing the bread down with your fingers, if necessary, to make sure all of pieces are submerged.
  • Sprinkle the blueberries over the bread, and, using your fingers, gently push some of the blueberries between the slices of bread. Sprinkle generously with Turbinado sugar. Cover the pan with plastic wrap and place in the refrigerator overnight.
  • In the morning, preheat the oven to 350°F. Remove the pan from the fridge and bake for 45 to 55 minutes, checking after 45. The bread should be golden brown and the custard fully absorbed and “cooked.” If you like a looser, softer custard, bake for closer to 45 minutes. And if you like a crispier French toast, bake for longer. I'm somewhere in between.
  • Serve immediately with confectioner's sugar lightly dusted on top.
