How To Make Cinnamon Roll Breakfast Casserole

Spray a 9x 13 inch casserole dish with pan spray. Preheat the oven to 350 degrees.
Open the cinnamon rolls and cut the cinnamon rolls each into 4 pieces. Place the cinnamon roll pieces in the bottom of the prepared pan.

Bake for 30-40 minutes or until cooked all the way through and no longer doughy in the middle. Take off the foil and let bake for 5 minutes uncovered at the end to help it become golden brown. Let the cinnamon roll casserole cool for 5-10 minutes before frosting.

Cinnamon Roll Casserole Variation Ideas

Add Nuts – Sprinkle chopped pecans or walnuts over the top of the casserole before baking. Try starting with half a cup. You can also mix them into the casserole if you prefer, I’d start with 1/2 a cup.

Try Adding Raisins – Maybe I’m dating myself or showing my Midwest roots, but raisins used to always be in cinnamon rolls and they are so tasty. It’s kind of like cinnamon raisin toast with cinnamon and sugar on top but better. Anyways if you like raisins, mix 1/2 a cup in when you add the custard and dough pieces together. It’s best if the raisins are in that custard mixture as they then stay plump and juicy. If your raisins are a little dried out and sticky, try placing them in warm water for five minutes to rehydrate them before adding them.

Swap The Heavy Cream – Heavy cream and heavy whipping cream are not quite the same, but are pretty close and can be swapped one for one. Half and half can also be swapped, but the casserole will taste less decadent. Milk could be used but I don’t recommend it, I found in my tests milk left the casserole feeling a little flat compared to using cream or half and half in my opinion.

Add Flavored Half And Half – An easy way to make a festive flavored cinnamon roll casserole is to use a flavored creamer meant for coffee. Different flavors are available at different times of year, but try flavors like hazelnut, vanilla, pumpkin spice, eggnog or gingerbread.

I’m not sure how well chocolate flavors will taste, the cinnamon may be a little overpowering with a chocolate based creamer. I would stay away from flavors that clash with cinnamon like mint for example.

How Do I Reheat This Cinnamon Roll Casserole?

The easiest way to reheat this easy cinnamon roll breakfast casserole recipe is to place a slice on a plate and heat it in the microwave for about 20-30 seconds.

You can also place the pan back in the oven covered at 350 for 15-20 minutes to reheat, the time will vary depending on how much is left in the pan. The frosting will melt into the casserole using this method, but it will still taste delicious.

This casserole can be enjoyed cold too, but I find it really tastes it’s best when warmed, especially as leftovers.

How Long Will Cinnamon Roll Casserole Last?

Expect this cinnamon roll casserole will last for about four days when stored in an airtight covered container in the refrigerator. If you are leaving it in the pan in the refrigerator I recommend covering it with some tight fitting cling wrap to keep it fresh. If you just add the aluminum foil to the top, it can dry out in the fridge.

While you probably could freeze pieces of this casserole after baking and reheat it, it tends to taste it’s best when enjoyed fresh.
