  • 8 eggs
  • 2 egg whites or 1 whole egg more
  • 1 tbsp olive oil plus more for the pan
  • 1 tsp minced garlic
  • ¾ tsp sea salt or more to taste
  • ground black pepper to taste
  • 4.5 oz (125 g) mozzarella cheese diced
  • 1 medium red onion finely chopped
  • 1 ½ cup baby spinach roughly chopped
  • 1 small red bell pepper diced
  • Preheat oven to 350°F (180°C) and grease a 9x13" baking dish with olive oil or cooking spray. Make sure you oil the dish very well, or the egg bake will stick.
  • In a large mixing bowl, add eggs, egg whites, olive oil, minced garlic, sea salt and ground black pepper. Whisk well to beat the egg with seasonings.
  • Add to beaten eggs diced mozzarella, chopped onion, diced red bell pepper and baby spinach. Stir well until completely combined.
  • Pour the mixture into the prepared dish. Make sure you spread it out evenly to ensure that both cheese and vegetables are well distributed.
  • Bake the egg casserole in hot oven for 25 to 40 minutes. It is ready when a toothpick inserted into the center comes out clean and the edges are golden brown.
  • Let cool for at least 10 minutes before serving.
