I was tired and lazy on this past Christmas Eve, thus I present to you my new Leftover Cinnamon Rolls French Toast Casserole. It is exactly what it sounds like. I walked into a store, bought 6 large cinnamon buns with frosting and pecans from some bakery in Surprise, Arizona and lazed right out on this recipe. To cut me a small amount of slack, I was cooking for 11.5 people daily during the Christmas break as my entire family was at my parent’s house in Arizona. (The .5 is my niece Elliette, who doesn’t really count as a full eater yet.)

How to Make a Cinnamon Roll Casserole

This casserole she didn’t eat but she certainly wolfed down my Double Cheese Overnight Hashbrown Casserole. Holy Dinah, did she ever. If you are wanting a savory casserole, that is the one for you!

This cinnamon rolls french toast casserole is for the sweet-toothed out there. You know who you are. You are me, my sister and my dad. Since there were 12 of us, I knew that I could get away with making a sweet and a savory casserole.

There were minimal leftovers, at best. I actually don’t recall any, but by the time I was done eating breakfast on Christmas Day, I was already neck-deep in prepping the turkey for Christmas dinner. The cleaning and the packing up was left to whomever wasn’t the cook that day, but I don’t recall any leftovers in the fridge.

To be honest we can’t be the only family that leaves breakfast out on the holidays and everyone eventually polishes it off, right? We don’t usually eat lunch on Christmas, we have breakfast that is out until early afternoon and then maybe, just maybe some leftovers from the Christmas Eve dinner make their appearance as well.

Now the reason that this cinnamon rolls french toast casserole works so well is that you aren’t using the canned tubes of cinnamon bun dough (hey, no judging here, those are fun as well) but you are using cinnamon buns as a baked BREAD. It’s already cooked so you are using it to soak up the milk and egg mixture and turn it into French toast. You want it baked up already in order to get the great texture.

What did you all make this past holiday season for breakfasts? Any hits? Any misses?

Happy cooking!

Love,

Ingredients

  • 8 large frosted cinnamon buns chopped into 1 inch pieces ( I used ones with pecans)
  • 8 eggs beaten
  • 2 cups of milk
  • 1 teaspoon vanilla
  • 1 teaspoon pumpkin pie spice
  • 1/2 cup white sugar

Instructions

  1. Grease a 9x13 pan and set aside.
  2.  Place the chopped cinnamon buns into a large bowl.
  3. Whisk together the eggs, milk, vanilla, spice and sugar. Pour over the bread and stir until the bread is coated completely.
  4. Pour into the 9x13 pan, spreading out evenly and pushing it down slightly to compress. Cover with foil and place in the fridge overnight.
  5. In the morning, pre-heat your oven to 350 °F.
  6. Place the pan in the oven and bake, covered, for 30 minutes. Remove the foil and continue baking for another 20-25 minutes until the center of the casserole is cooked and set and has reached a minimum temperature of 165 °F.
  7. Remove, cool slightly, slice and serve.

    Not sweet enough, I feel like cinnamon would have been a better choice over pumpkin spice. Although a great way to use leftovers but just bland.5 stars

    • BRIE says

      Hey Debi,
      I use dark brown sugar instead of white sugar, and yes cinnamon or all spice; I have not ventured with the pumpkin spice yet for the bread casserole, maybe if I used it with plan french bread? and I don’t measure, only to my taste.
      So, for your sweet tooth, remember your adding maple syrup after it’s done.

      thanks Magpie for sharing this recipe, I also have used raisin cinnamon bread from CostCo that is my favorite, and I have used the italian cake panettone bread that comes out around the holidays.

      I really like the idea of using the cinnamon buns for this recipe that is what excites me !

    I may be late to your party but… I haven’t made this yet, I gave it 5 stars because it is exactly what I was looking for and it sounds amazing. All of the other recipes called for tubed cinnamon roll dough, this one did not. I’m going to make this for my hubby and myself.5 stars
