Anytime I find a recipe that you can prepare the day before is a winner in my book. Just like my Cinnamon Pull-Apart Bread, this Sourdough French Toast Casserole is made the night before and then baked the next morning for the most delicious breakfast ever.

I love this recipe for brunch, breakfast for a crowd, or holiday breakfasts like Christmas when I need to feed a crowd in a hurry. French Toast Casserole is also a great way to use stale bread or bread that is about to go bad so you don’t waste any of it.

Ingredients Needed to Make a Sourdough French Toast Bake

From the pantry, you will need a loaf of bread (or most of the loaf), sugar, nutmeg, vanilla, flour, brown sugar, cinnamon, salt, and chopped pecans.

From the fridge grab some eggs, milk, heavy cream, and unsalted butter.

How to Make French Toast Casserole with Sourdough Bread

  1. Prepare a baking dish with non-stick spray. Cut the loaf of bread into bite-sized cubes and place them in the pan in an even layer.
  2. Whisk together the eggs, milk, cream, sugar, nutmeg, and vanilla. Pour the mixture over the bread cubes and use a large spoon to mix and coat all of the pieces. Cover the dish with plastic wrap and refrigerate overnight.
  3. The next morning, preheat the oven to 350°F. Give the bread a gentle stir to make sure the egg mixture is distributed evenly. Make the topping by combining the flour, brown sugar, cinnamon, salt, and cubed cold butter. Use a pastry cutter, a fork, or your hands to combine the mixture into a crumble. Mix in the pecans and spread out evenly over the top of the casserole.
  4. Bake for 45 minutes.

Tips for the Best Baked French Toast Casserole

  • Even if you don’t have a full loaf of bread, you can make this recipe! You can also use any rustic bread, not just sourdough like french bread, brioch, or challah.
  • Make sure you give the bread cubes a stir before you refrigerate the casserole overnight so that all of the pieces have been coated.
  • The next day, give the bread another gentle mix so that the egg mixture gets evenly distributed.
  • The pecans in the topping are optional, but add a nice crunch and flavor to the casserole. If you don’t have pecans, you can substitute walnuts or almonds.
  • When you serve this dish, don’t forget the maple syrup for one more layer of flavor. You can also sprinkle it with powdered sugar or top it with whipped cream for the ultimate breakfast.
  • Refrigerate any leftovers covered in the fridge for 1-2 days.
