Make this decadent Cinnamon Roll French Toast Casserole ahead of time for a simple, gooey, and sweet weekend brunch. It combines the flavors of cinnamon rolls and French toast into one baked dish.

Ingredients

Scale
  • 1 (12.4 ounce) package refrigerated cinnamon rolls with icing
  • 6 large eggs
  • 1 cup milk (whole or 2%)
  • 1/2 cup heavy cream
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt
  • For the Glaze (Optional): 4 ounces cream cheese, softened; 1/2 cup powdered sugar; 1 tablespoon milk

Instructions

  1. Lightly grease a 9×13 inch baking dish.
  2. Separate the cinnamon rolls. Place the dough pieces in the prepared baking dish, spacing them out slightly. Keep the icing packets aside for later.
  3. In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined. This forms your custard.
  4. Pour the egg custard evenly over the cinnamon roll pieces in the baking dish. Gently press down on the rolls so they absorb some of the liquid.
  5. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight. This step allows the bread to soak up the custard.
  6. When ready to bake, preheat your oven to 350°F (175°C). Remove the plastic wrap.
  7. Bake for 30 to 35 minutes, or until the casserole is puffed, golden brown, and the center is set. If the top browns too quickly, loosely cover it with foil.
  8. While the casserole bakes, prepare the glaze. In a small bowl, beat the softened cream cheese until smooth. Gradually beat in the powdered sugar and 1 tablespoon of milk until you reach a smooth, drizzly consistency.
  9. Remove the casserole from the oven. Let it cool for 5 minutes.
  10. Open the reserved icing packets from the cinnamon rolls and drizzle them over the warm casserole.
  11. If using the cream cheese glaze, drizzle it over the top as well. Serve warm.

Notes

  • Using day-old bread or slightly stale brioche instead of refrigerated rolls gives a better texture for soaking up the custard.
  • For a richer flavor, consider adding a tablespoon of maple syrup to the egg custard mixture.
  • This casserole is a great option for meal planning; prepare it Sunday night for a quick Monday morning treat.
