Ingredients

Scale

Egg Mixture

  • 8 large eggs
  • 1/2 cup milk (dairy or non-dairy)
  • 1 cup shredded cheddar cheese
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Vegetables

  • 1 tablespoon olive oil
  • 1 small onion, diced
  • 1 red bell pepper, diced
  • 1 zucchini, diced
  • 1 cup baby spinach, chopped

Optional Toppings

  • Sliced green onions
  • Hot sauce


Instructions

  1. Preheat Oven and Prepare Baking Dish: Preheat your oven to 375°F (190°C) and lightly grease a 9×9-inch baking dish or a similar-sized dish to prevent sticking.
  2. Sauté Vegetables: Heat the olive oil in a skillet over medium heat. Add the diced onion and red bell pepper, cooking for about 3 to 4 minutes until they soften. Next, add the diced zucchini and continue cooking for an additional 2 minutes. Stir in the chopped spinach and cook just until it wilts. Remove the skillet from the heat.
  3. Mix Egg Base: In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until well combined.
  4. Combine Ingredients: Stir the shredded cheddar cheese and sautéed vegetables into the egg mixture until evenly distributed.
  5. Fill Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly across the dish.
  6. Bake: Place the baking dish in the oven and bake for 30 to 35 minutes, or until the center is set and the top is lightly golden brown.
  7. Cool and Serve: Allow the casserole to cool for about 5 minutes before slicing. Add optional toppings like sliced green onions or hot sauce as desired, then serve warm.
