Overnight French Toast Casserole

This make-ahead French toast bake combines the classic flavors of traditional French toast with the convenience of a casserole that can be prepared hours or even a day in advance. The magic happens overnight as the bread soaks up the rich, cinnamon-infused custard, resulting in a perfectly moist interior and caramelized, slightly crisp top layer that will have everyone asking for seconds.

Equipment

  • 9x13-inch Baking Dish
  • Mixing Bowls
  • Whisk

Ingredients
  

For the Casserole

  • 1 loaf brioche or French bread day-old, 16 oz, cut into 1-inch cubes
  • 8 large eggs
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar packed
  • 2 tbsp pure vanilla extract
  • 1 tbsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1/4 tsp salt

For the Topping

  • 1/4 cup unsalted butter softened
  • 1/3 cup brown sugar packed
  • 1/4 cup all-purpose flour
  • 1/2 tsp ground cinnamon
  • 1/8 tsp salt
  • 1/2 cup chopped pecans or walnuts optional

Instructions
 

  • Generously grease a 9x13-inch baking dish with butter or cooking spray. For easy cleanup, consider lining with parchment paper with overhanging edges.
  • Cut the bread into 1-inch cubes. If using fresh bread, dry it out by spreading cubes on a baking sheet and placing in a 200°F oven for about 10 minutes. Arrange bread cubes evenly in your prepared baking dish.
  • In a large bowl, whisk together eggs, milk, heavy cream, sugars, vanilla, cinnamon, nutmeg, and salt until completely combined and smooth.
  • Pour the custard mixture evenly over the bread cubes, making sure all pieces are coated. Gently press down on the bread to help absorption.
  • In a medium bowl, combine softened butter, brown sugar, flour, cinnamon, and salt until the mixture resembles coarse crumbs. Stir in chopped nuts if using.
  • Cover the casserole dish tightly with plastic wrap and refrigerate for at least 8 hours or overnight (up to 24 hours).
  • When ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for about 30 minutes while you preheat your oven to 350°F.
  • Sprinkle the prepared topping evenly over the soaked bread. Bake uncovered for 45-50 minutes, or until puffed, golden brown, and set in the center. A toothpick inserted in the center should come out clean.
  • Allow the casserole to cool for 5-10 minutes before serving. Drizzle with maple syrup, dust with powdered sugar, or top with fresh berries before serving.

Notes

- Day-old bread works best as it absorbs the custard more effectively than fresh bread.
- For a dairy-free version, substitute almond milk and coconut cream.
- Try challah bread for an even richer flavor profile.
- You can prepare this casserole up to 24 hours in advance.
- Leftovers can be refrigerated for up to 3 days or frozen for up to 2 months.
