If your house is anything like ours on Christmas morning it’s an early start and I can tell you I don’t want to be messing around chopping, mixing and layering food for a casserole. Instead, I make this on Christmas Eve night and place it in the refrigerator overnight and then take it out and pop it in the oven on Christmas day.

I also put the ingredients in the crockpot for our French toast and blueberry breakfast casserole so that there is a savoury and sweet option for Christmas morning especially when we have all the family together.

On Christmas morning the timer switches on the crock pot about 4am and then at about 6:30 I come down and get the casserole out of the fridge and start it cooking.

That means that just before 8am we can sit down and enjoy our breakfast together.

Christmas Breakfast Casserole Ingredients

This is delicious, it’s inspired by my sausage, egg and cheese breakfast casserole but to give it a festive flair I’ve added some red and green sweet peppers and used frozen diced potatoes to save a little time.

If I have time I sometimes use my homemade Italian Sausage in the recipe as it adds a little bit of spice to it that my father-in-law loves.

Easy Make Ahead Christmas Breakfast Casserole

This recipe is going to take you about 15 minutes to make. So it’s quick and easy. You’re going to need a 9x13inch baking dish. I love my pyrex one and because it’s glass you can really see the holiday colors of the peppers once cooked.

I start with a potato and pepper layer at the bottom – this makes it a lot easier to slice and serve the casserole than the sausage layer. Then sprinkle with some cheese that will melt in.

After it’s the sausage layer which will peek through the egg mixture when cooked and brown nicely and a sprinkle of cheese to top it all off.
