Create the ultimate sweet breakfast fusion with this easy Cinnamon Roll French Toast Casserole. It combines soft cinnamon rolls, rich custard, and a sweet glaze for an indulgent brunch everyone loves.

Ingredients

Scale
  • 1 (12.4 ounce) package refrigerated cinnamon rolls (with icing)
  • 6 large eggs
  • 1 cup whole milk
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 cup granulated sugar
  • 1/4 cup maple syrup (for serving)

Instructions

  1. Grease a 9×13 inch baking dish.
  2. Prepare the cinnamon rolls according to package directions for baking, but instead of placing them in the provided pan, cut each roll into four equal pieces.
  3. Arrange the cut cinnamon roll pieces evenly in the prepared baking dish.
  4. In a large bowl, whisk together the eggs, milk, vanilla extract, ground cinnamon, nutmeg, and granulated sugar until well combined. This creates your cinnamon custard.
  5. Slowly pour the cinnamon custard evenly over the cinnamon roll pieces in the baking dish, making sure all pieces are coated.
  6. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight, to allow the bread to soak up the custard.
  7. When ready to bake, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Remove the plastic wrap.
  8. Bake uncovered for 35 to 45 minutes, or until the casserole is puffed, golden brown, and the center is set. If the top begins to brown too quickly, loosely cover it with foil.
  9. While the casserole bakes, prepare the icing packets that came with the cinnamon rolls according to package directions.
  10. Remove the casserole from the oven. Drizzle the warm icing over the top.
  11. Slice and serve warm with extra maple syrup. This recipe is a great alternative to complicated meal planning when you want a special weekend treat.

Notes

  • For an extra gooey texture, you can use a sous-vide precision cooker to gently warm the milk before mixing the custard, though this step is optional.
  • If you skip the overnight soak, let the assembled casserole sit at room temperature for 30 minutes before baking.
  • This dish is a fantastic make-ahead breakfast for busy mornings or holiday gatherings.
  • If you are looking for ways to manage your diet alongside indulgent meals, consider pairing this with a structured keto meal plan delivery for the rest of the week.
