This croissant breakfast egg casserole is super tasty and so easy to prepare. It is the perfect meal to toss in the oven for breakfast if you’re feeding over-night guests, but it is also a simple dinner that feeds a crowd without breaking the bank!

This breakfast casserole is one of my favorite things to make for breakfast because it’s always a hit with my family.  Some of my other no-fail breakfast recipes are my grandma’s famous Homemade Pancakes, Belgian Waffles or these easy Breakfast Sandwiches.

Easy Breakfast Egg Casserole

Are you ready to make an easy breakfast egg casserole that will replace all other recipes you may have tried over the years? THIS.IS THE.BEST.

My grandma used to make a very similar breakfast casserole loaded with eggs and cheese, and it was delicious. But I took her simple recipe and made it even better by adding breakfast meats and a delicious crescent roll crust. This recipe went from tasty to spectacular! (Sorry grandma!)

This is our go-to recipe and I make it probably once a month. My husband requests it, and my kids always devour the entire dish!  And did I mention how easy it is to make?

I figured since it was that time of year when plenty of people will be hosting house guests for the holidays, this recipe might make your life easier as well as give your friends and family something delicious to talk about. You’re welcome.

Croissant Breakfast Casserole Ingredients

The great thing about this recipe is that you can mix and match the ingredients to customize it however you like.  Think of this recipe like an omelet and throw in everything you would normally put in one of those.  Aside from the first couple of ingredients, the rest are optional.  Here’s what you need with some other suggestions of what to include.

  • Refrigerated crescent dinner rolls
  • Eggs
  • Milk
  • Pepper
  • Your favorite cheese
  • Ham
  • Sausage
  • Bacon
  • Steak
  • Green onions
  • White onions
  • Bell peppers
  • Avocado
  • Mushrooms

How to Make A Breakfast Egg Casserole

You’ll start by spraying a casserole dish with cooking spray, then roll out your crescent dough across the bottom and press the seams together to make one giant piece of dough. Sprinkle your choice of meat on top of the dough. I always have lunch meat on-hand, so I use sliced ham often. We also like cooked crumbled sausage that you buy in a bag in the freezer section or even precooked bacon.

Next, pour a mixture of eggs and milk with a little pepper on top.

And then top with shredded cheese. We use a mixture of cheddar and mozzarella, but you can use whatever you’d prefer!

Bake for 25 minutes or until the egg is set, then sprinkle with fresh parsley. I also LOVE adding sliced green onions to this breakfast egg casserole, but my 4 year old is not a fan!

Slice and serve and you’re good to go!  If you would like to see the video we made of the entire process, it’s down below in the recipe card.

How To Store This Recipe

If you have any leftover breakfast casserole, be sure to put it in an airtight container and store it in the refrigerator.  It should stay fresh for about 5 days.  I always make an extra batch so that my kids can have more for breakfast throughout the week and it will typically last all week assuming they don’t forget to put in back in the fridge when they’re done eating it.

You can also make this ahead of time and freeze it to be used down the road.  It will stay good for about 2 months if you first cover it in plastic wrap and then put a layer of aluminum foil around it.  I’ll transfer the egg breakfast casserole to a disposable casserole pan before freezing it so I’m not down a pan in the kitchen.

When you’re ready to eat it, let it thaw overnight in the fridge and then you can reheat it in the oven at 350 degrees F for about 20 minutes or until it has been heated throughout.
