We love to make this for Christmas breakfast, but you could make this any time you want a yummy, easy to throw together casserole. We love that you can make it ahead so all you have to do is pop it into the oven in the morning.

This casserole is not only super easy to make, but has a great flavor. The toasted croutons  make a perfect substance that isn’t mushy like strata or crunch like topping. YUMMY!

Make Ahead Breakfast Casserole Recipe

Christmas morning casserole recipe

In a bowl mix together:
  • 6 eggs
  • 2 cups half and half (it makes it richer than milk)
  • 1 teaspoon ground mustard
  • 1/2 teas salt

add croutons to your breakfast casserole

Now add 1 bag of croutons (5 oz) – we used garlic & cheese.

If you’d like you can add 3/4 cup cooked bacon, ham, or sausage.

Stir and pour into 9x13 pan.

add cheese
Sprinkle 2 cups of grated cheddar cheese on the top of your casserole.
 top with festive peppers if you like
I sprinkled with chopped, sweet red peppers and sliced green onions. It’s optional, but it not only added some healthy veggies, but also made it very festive for Christmas breakfast.

Cover and put in the fridge overnight. It can be made up to 3 days ahead of time.

Christmas Casserole Recipe you can make ahead
On Christmas morning just pull the casserole out of the fridge and allow the pan to come to room temperature while the oven preheats to 325 F.  (During this time we whip up a batch of our favorite Christmas drink – Wassail).

Cover and bake 45 minutes. (This is the perfect amount of time to unwrap presents! The casserole is ready just as we finish opening everything up. After breakfast it’s time to PLAY!)

NOTE: The picture shows the time I accidentally cooked the casserole uncovered so it got a little more brown on the top and edges than we like. But I loved the Christmas plates….. so that’s the one I choose =)
