Step 1

Grease a 9-inch square baking dish with butter. Set aside until ready to use.

Step 2

To a medium bowl, add eggs, milk, maple syrup, vanilla extract, cinnamon, and salt. Whisk until well combined.

Step 3

To the prepared baking dish, add ⅓ of the pieces of bread in a single layer. Top with ⅓ of the butter cubes. Repeat 2 times until all of the bread and butter cubes are in the pan.

Step 4

Pour the egg and milk mixture over the bread cubes. Press the bread cubes down into the egg mixture to make sure all of the bread is coated.

Step 5

Cover with a piece of greased aluminum foil. Refrigerate for at least 8 hours, or up to 24 hours before baking.

Step 6

The next morning, place the covered pan in a cold oven. Heat the oven to 350°F and bake for 50 minutes.

Step 7

Remove the foil and bake for an additional 10 minutes, or until the top of the casserole is golden brown, the butter is bubbly, and the internal temperature reaches 160°F.

Step 8

Remove the pan from the oven and let the casserole rest for 5-10 minutes before serving.

Step 9

Serve hot and drizzle with maple syrup. Enjoy!
