Ingredients 

  • 12 large eggs
  • 12 oz fresh spinach
  • 2 cups shredded mozzarella cheese
  • 1/2 cup green onions thinly sliced
  • 2 tsp olive oil
  • 2 tsp all-purpose seasoning
  • freshly ground black pepper to taste

Instructions

  • Preheat your oven to 375°F (190°C). Prepare a 9x13 inch casserole dish by coating it with nonstick cooking spray.
  • Heat olive oil in a large skillet over medium heat. Sauté the fresh spinach, stirring constantly, for approximately 2 minutes until it has completely wilted. Spread the wilted spinach evenly across the bottom of the prepared dish.
  • Layer the shredded mozzarella cheese and thinly sliced green onions directly over the spinach. Season generously with all-purpose seasoning and black pepper to taste.
  • In a large bowl, whisk the eggs until they are well-combined and airy. Pour the egg mixture evenly over the layers in the casserole dish.
  • Bake for 25-30 minutes, or until the egg mixture is fully set and the top begins to turn a light golden brown. Let the casserole rest for 5 minutes before slicing.
  • Serve the spinach egg casserole hot. Store any leftovers in an airtight container in the refrigerator and reheat in the microwave for a quick and easy meal.

Equipment

  • 9x13 inch casserole dish
  • Large Skillet
  • Mixing bowl

Notes

For ingredient substitutions, feel free to use frozen spinach; just be sure to thaw it and squeeze out all excess water before use. Other cheeses like cheddar, Gruyère, or feta also work beautifully. To store, cover the casserole tightly or place individual slices in an airtight container in the refrigerator for up to 4 days. Reheat single servings in the microwave for 60-90 seconds.
