How to Make The Best Egg Bake Casserole Recipe

Below is an overview of the ingredients and instructions for this recipe. Be sure to scroll down to the recipe card below for the complete details and nutrition information! 

Ingredients

  • Pita Bread – Use store-bought or homemade pita bread for the base of the egg bake. 
  • Olive Oil – This is used to sauté the veggies, adding a savory, peppery taste. 
  • Veggies – Red onion, tomatoes, and baby spinach add vibrant notes of color and tons of nutrients and fiber. 
  • Olives – We recommend using Kalamata olives, but any olives you like best will work. Or, omit them completely if you’re not a fan. 
  • Cheese – A combination of crumbled feta cheese adn shredded mozzarella cheese adds a salty, savory taste and makes this casserole satisfying melty. 
  • Large Eggs – You can’t have an egg bake casserole without eggs! 
  • Milk – Full-fat milk will create the richest flavor, but any milk you have on hand will work. 
  • Seasonings – Dried oregano, salt, and black pepper enhance the savoriness, making this recipe extra delicious. 

Instructions

  1. Prepare. Preheat your oven, and grease a large baking dish with cooking spray. 
  2. Sauté. Heat the oil in a large skillet over medium-high heat. Add the diced red onion, and sauté until it’s lightly golden. Add the spinach to the pan, and sauté until it is wilted. Then, stir in the olives and diced tomatoes. 
  3. Layer. Arrange the sliced pita bread in the bottom of the prepared baking dish. Layer the vegetable mixture on top followed by the feta and mozzarella. 
  4. Prepare the eggs. In a separate bowl, whisk the eggs, milk, oregano, salt, and pepper until smooth. Pour the mixture over the ingredients in the baking dish. 
  5. Rest. Allow the mixture to rest so the bread absorbs the liquid, similar to French toast
  6. Bake. Transfer the baking dish to the preheated oven, and bake until it is puffed up and starting to brown. 
  7. Rest. Allow the egg bake to cool slightly. Then, slice, and serve warm!

Can I Make This Recipe Ahead of Time? 

Yes! To make this egg bake casserole ahead of time, assemble all the ingredients in the baking dish. Then, cover it with aluminum foil, and store it in the fridge overnight. 

Bake as usual when you’re ready to eat, adding a few minutes as needed for the ingredients to heat through. 

How to Store and Reheat

  • Store leftovers covered with foil or in an airtight container in the fridge for up to four days in the refrigerator. 
  • We don’t recommend freezing this recipe as it’s likely to become soggy once thawed! 
  • Reheat your egg bake in the oven covered with foil, or warm individual portions in the microwave. 

Common Questions About This Easy Egg Bake Casserole Recipe

Why is my egg bake rubbery? 

If your casserole turns out rubbery, it’s likely either because it was overbaked or the veggies had too much moisture. Be sure to sauté them first to prevent this from happening! 

What’s the difference between a frittata and an egg casserole? 

A frittat is made by briefly cooking eggs and various ingredients in a skillet on the stove before transferring them to the oven. Meanwhile, an egg casserole features layers of ingredients combined in a casserole dish and baked completely in the oven. 

Why is my egg casserole not done in the middle? 

This is likely because the vegetables still contained a lot of water when the dish was transferred to the oven or too high of a heat was used. Try reducing the oven temperature slightly, and continue to bake until the center sets. Cover the dish with foil if the top begins to brown too quickly!
