  6. Fold the cooked spinach mixture into the egg mixture.
  7. Stir in the crumbled feta and shredded mozzarella or cheddar if using.
  8. Pour the mixture into the prepared baking dish and spread evenly.
  9. Bake for 30–35 minutes, or until the center is set and the top is lightly golden.
  10. Let the casserole rest for 5–10 minutes before slicing.
  11. Garnish with fresh parsley or chives and serve warm.

Notes

  • Frozen spinach may be used if thawed and excess moisture is squeezed out.
  • Prepare the casserole the night before and refrigerate until ready to bake.
  • Add sun-dried tomatoes, olives, mushrooms, bell peppers, bacon, sausage, or ham for extra flavor.
  • Use dairy-free milk and cheese alternatives for a dairy-free version.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 2 months.
  • Reheat individual portions in the microwave or warm the casserole in a 325°F (160°C) oven until heated through.
