Ingredients

Vegetables

  • 4 cups fresh spinach, chopped (or 2 cups frozen spinach, thawed and drained)
  • 2 cloves garlic, minced

Dairy

  • 1 cup crumbled feta cheese
  • 4 large eggs
  • 1 cup heavy cream
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese

Spices and Seasonings

  • 1 teaspoon dried oregano
  • Salt to taste
  • Black pepper to taste

Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) to prepare for baking the casserole.
  2. Mix Wet Ingredients: In a large mixing bowl, whisk together the eggs, heavy cream, minced garlic, dried oregano, salt, and pepper until well combined.
  3. Add Spinach and Cheeses: Stir the chopped spinach, crumbled feta cheese, and half of the shredded mozzarella cheese into the egg mixture evenly.
  4. Prepare Baking Dish: Grease a 9 by 9-inch baking dish to prevent sticking, then pour the spinach and cheese mixture into the dish.
  5. Top Casserole: Sprinkle the remaining mozzarella cheese and the grated Parmesan cheese over the top to create a golden crust when baked.
  6. Bake: Place the casserole in the preheated oven and bake for 35 minutes or until the casserole is set and the top is golden brown.
  7. Cool and Serve: Allow the casserole to cool for a few minutes before slicing to let it set fully, then serve warm.

Notes

  • Use fresh spinach for the best flavor, but frozen spinach can be used if thawed and fully drained to avoid excess moisture.
  • The casserole can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • For a dairy-free version, substitute cheeses with vegan alternatives and use coconut or almond milk instead of heavy cream.
  • Add a pinch of nutmeg or red pepper flakes for extra flavor variation.
  • If you prefer a crispier top, broil the casserole for the last 2-3 minutes of cooking, watching carefully to prevent burning.
