Ingredients

Units Scale

Main Ingredients

  • 1 loaf brioche, Texas toast, or thick French bread (12 slices)
  • 6 large eggs
  • 3/4 cup half-and-half cream
  • 1/2 cup Baileys Irish Cream (or substitute Baileys coffee creamer Irish Cream non-alcoholic)
  • 4 tablespoons brown sugar
  • 2 teaspoons vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 cup maple syrup

Toppings

  • Powdered sugar, for dusting
  • Additional cinnamon, for sprinkling
  • Whipped cream, for serving
  • Green sprinkles (optional, for garnish)

Instructions

  1. Prepare the casserole dish: Generously spray a 9 x 13-inch casserole dish with non-stick cooking spray. Arrange the 12 slices of bread in two layers, overlapping slightly—lay 2 rows of 3 slices on the bottom, then repeat for the second layer on top.
  2. Mix custard: In a large bowl, whisk together the eggs, half-and-half cream, Baileys Irish Cream, brown sugar, vanilla extract, cinnamon, and maple syrup until thoroughly blended.
  3. Soak bread: Pour half of the custard mixture evenly over the first layer of bread slices, then pour the remaining half over the second layer, ensuring all bread pieces are well soaked.
  4. Refrigerate overnight: Cover the casserole tightly with aluminum foil, spraying underside of foil with non-stick spray to prevent sticking. Refrigerate for about 8 hours or overnight to allow bread to absorb the custard.
  5. Preheat oven: Remove casserole from fridge while preheating oven to 350 degrees F (176 degrees C). Keep the casserole covered with foil as it comes to room temperature.
  6. Bake covered: Bake the casserole in the preheated oven for 1 hour, ensuring a very tight foil seal to prevent sogginess. Add a second foil layer if needed for sealing.
  7. Bake uncovered: Remove foil and bake uncovered for an additional 10 minutes until the top is lightly browned and slightly crisp.
  8. Rest and serve: Let the casserole stand uncovered for 5 minutes before garnishing. Dust with powdered sugar, sprinkle additional cinnamon, add whipped cream, and optionally sprinkle green sprinkles. Serve warm.

Notes

  • This casserole is perfect for St. Patrick's Day or any festive brunch occasion.
  • For a non-alcoholic version, substitute Baileys Irish Cream with Baileys coffee creamer Irish Cream.
  • Use brioche or thick cut bread to ensure a tender custard texture and rich flavor.
  • Spraying the underside of the foil prevents sticking and helps maintain a smooth top surface.
  • A very tight foil seal during baking is crucial to avoid sogginess.
  • Letting the casserole rest before serving allows it to set and slice more easily.
