This Cinnamon Roll Casserole is a quick, festive, and comforting brunch dish perfect for Christmas morning. It combines gooey cinnamon rolls with a rich custard base and a sweet vanilla glaze for a crowd-pleasing treat.

Ingredients

Scale
  • 2 cans refrigerated cinnamon rolls (with icing, each 12.4 oz)
  • 4 large eggs, room temperature
  • 1 cup whole milk (can substitute half-and-half, heavy cream, or unsweetened almond milk)
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • Reserved cinnamon roll icing (from the cans)
  • Optional: 2 tablespoons unsalted butter, melted
  • Optional: 1/4 cup chopped pecans or walnuts
  • Optional: 1/4 cup raisins or dried cranberries

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
  2. Cut the cinnamon rolls from both cans into quarters. Scatter the pieces evenly in the baking dish.
  3. In a medium mixing bowl, whisk together eggs, milk, sugar, vanilla extract, and ground cinnamon until smooth.
  4. Pour the custard mixture evenly over the cinnamon roll pieces, pressing down gently to soak.
  5. Sprinkle optional toppings like nuts or dried fruit, and drizzle with melted butter if desired.
  6. Bake uncovered for 35-40 minutes, or until puffed, golden brown, and the custard is set. Cover loosely with foil if browning too quickly.
  7. Test for doneness: casserole should be firm in the center and pull away from the sides. Bake an additional 5-7 minutes if needed.
  8. Cool for 10 minutes before serving.
  9. Drizzle reserved icing over the warm casserole. Microwave icing for 10-15 seconds if too thick.
  10. Serve warm and enjoy.

Notes

For best results, use room temperature eggs and milk. You can assemble the casserole the night before and bake fresh in the morning. For gluten-free or dairy-free adaptations, use appropriate cinnamon rolls and milk substitutes. Let the casserole cool for 10 minutes before serving for easier slicing and better texture. Leftovers keep well in the fridge for up to 3 days and can be frozen for up to 1 month.
