I look forward to Christmas brunch all year long. It is one of my favorite meals of the year to enjoy with family and friends. We go all out and make all of our favorite breakfast foods. I always make sure we have a breakfast casserole on the menu because they are easy to make and a real crowd pleaser.

This Caprese Breakfast Casserole is going on our menu this year. It is the perfect breakfast casserole for the holidays because it is pretty to serve and so delicious!  It is made with mozzarella cheese, tomatoes, and fresh basil, just like the traditional caprese salad, but in an egg casserole. Our family loves it and I think you will too!

How to Make Caprese Breakfast Casserole

Breakfast casseroles are perfect for entertaining because they feed a crowd and come together in no time. All of the ingredients go into one pan and the casserole gets baked in the oven. You can’t beat that!

  • First, sauté the onion and garlic in olive oil  and set aside.
  • For this breakfast casserole recipe, you will need 18 large eggs. Yes, 18! The recipe makes a 9×13-inch pan and you want a nice, thick egg casserole. Whisk the eggs and milk together.
  • Stir in one cup of the shredded mozzarella cheese, reserving ½ cup for the top of the casserole. Add the tomatoes, fresh basil, salt, and pepper.
  • I like to use halved grape tomatoes for this recipe because they aren’t too juicy and hold up nicely.
  • Make sure you use FRESH basil, not dried. Fresh basil has SO much flavor and will add a pretty green color to the casserole. Do not chop the basil finely, give it a rough chop so you still have decent size basil leaves to stir into the casserole.
  • Pour in a greased 9×13-inch pan and sprinkle the remaining shredded mozzarella cheese over the top of the casserole.
  • Place the pan in the oven and bake for 45 to 60 minutes. You don’t need to cover the casserole. You will know when the breakfast casserole is done when the top is golden brown and the eggs are firm to the touch. The casserole shouldn’t be jiggly.
  • Remove from the oven and let cool for 10 minutes before cutting into squares.
  • Store the cooked breakfast casserole covered in the refrigerator for up to 4 days.

Can you Make Breakfast Casserole in Advance?

Yes! You can prep all of the ingredients the day or night before and put them into the pan. Cover the pan with plastic wrap and store in the refrigerator until you are ready to bake. Your guests will think you woke up super early to make them a fancy breakfast. They will never know you prepped it the day before and just had to put it in the oven. That will be our little secret:)

Can you Freeze Breakfast Casserole?

Yes! If you are going to freeze a whole breakfast casserole, bake it in a disposable baking pan so you don’t have to freeze your fancy casserole dish or pan you use all of the time. Make sure you cool the casserole completely and cover it with plastic wrap and aluminum foil. Freeze for up to 2 months. You can reheat the full casserole in the oven.

You can also freeze individual servings of the baked breakfast casserole. Cut the breakfast casserole into squares and freeze in small freezer container or wrap each square in plastic wrap and aluminum foil. You can reheat individual servings in the microwave, making a great breakfast on the go!

  1. Mmm…all my favorite ingredients in one dish! Perfect for feeding a crowd. I want to come to your Christmas brunch!

  2. Hello! 
    I’m very interested in making this recipe, however, is there a way to cut back on the number of whole eggs I use, and replace it with egg whites?  Or would you suggest something else. I don’t want to compromise the recipe too much. 

  3. Wow what a yummy breakfast, I bet my hubby wood like it sure!! I would be delighted to get glimpse of this!

  4. 5 stars
    Great breakfast recipe! Made a half batch of this the other day in an 8×8 pan and it turned out well! Thanks for the recipe!

    A new family favorite!! I thought it was a great recipe for the vegetarians, but it turned out that everyone loved it!

    I am loving your recipes.  I made the Caprese Casserole on Christmas morning, it was a big hit.  I made a smaller version – with only 6 eggs and a 8 X 8 baking dish.  The recipe is very adaptable.  
    Thanks again

    I made this today and was fabulous. I have an 8 week old baby and toddler so really wanted something I could semi prepare in advance of guests arriving. This was simple, easy and delicious! Will be back for more recipes!

  8. We’re trying to stay away from so much dairy. Could i cook the same amount of sausage and add it instead of using the cheese?

  9. I appreciate that this recipe does not have potatoes! <3 Being diabetic requires low-carb eating and most breakfast bakes/casseroles are made with a potato base. It's great to see one that isn't. Thank You!

    This is great and healthy! I like that it doesn’t contain sour creamier many of the other breakfast casseroles I’ve made in the past. I didn’t have mozzarella cheese so I used up some feta, Parmesan and cheddar and it was tasty!

    1. Fresh mozzarella is fine. You can shred it or if you are using the small mozzarella balls you can cut them in half.

    Made this for Thanksgiving breakfast. Prepped the night before and let sit in the fridge. Family loved it – asked multiple times “How’d you get the eggs so fluffy.”

    Loved this recipe and these flavors blend so well together!
    I made this for Thanksgiving and our family loved it!
    I was wondering… If I didn’t have any basil, could I substitute with spinach? Basil goes well with tomatoes, but I was wondering if I could substitute with spinach at a pinch?
