Ingredients

Scale

Vegetables

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

Dairy & Eggs

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

Seasonings

  • 1 teaspoon dried oregano
  • Salt and pepper to taste

Instructions

  1. Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking the casserole evenly.
  2. Mix wet ingredients and seasonings: In a large mixing bowl, whisk together the eggs, heavy cream, minced garlic, dried oregano, salt, and pepper until fully combined.
  3. Add spinach and cheeses: Stir in the chopped fresh spinach (or thawed and drained frozen spinach), crumbled feta cheese, and half of the shredded mozzarella cheese. Mix gently to combine all ingredients evenly.
  4. Prepare the baking dish: Grease a 9×9-inch baking dish lightly to prevent sticking. Pour the spinach and cheese mixture into the dish and spread it out evenly.
  5. Add cheese topping: Sprinkle the remaining mozzarella and the grated Parmesan cheese evenly on top of the casserole mixture for a golden, cheesy crust.
  6. Bake the casserole: Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the casserole is fully set and the top turns a golden brown color.
  7. Cool and serve: Remove the casserole from the oven and allow it to cool for a few minutes to set further before slicing and serving warm.

Notes

  • Use fresh spinach for best texture, but frozen spinach works well when thawed and thoroughly drained.
  • You can substitute the oregano with Italian seasoning for a different herb flavor.
  • For a nuttier taste, try adding a handful of chopped walnuts on top before baking.
  • This casserole is keto-friendly and suitable for low-carb diets.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days; reheat before serving.
