Instructions to Prepare Greek Breakfast Casserole

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C) and grease an 8×8-inch or 9×9-inch baking dish with butter or non-stick spray.

Step 2: Sauté the vegetables

In a skillet, heat olive oil over medium heat. Add onion and cook for 2–3 minutes until softened. Stir in spinach and cook until wilted. Remove from heat and let it cool slightly.

Step 3: Whisk the egg mixture

In a large bowl, whisk together eggs, milk, salt, pepper, and oregano until smooth.

Step 4: Combine ingredients

Stir the cooked spinach mixture, cherry tomatoes, olives, and half of the feta cheese into the egg mixture. Pour it evenly into the prepared baking dish.

Step 5: Add the topping

Sprinkle the remaining feta cheese on top for a golden, cheesy finish.

Step 6: Bake the casserole

Bake for 35–40 minutes, or until the eggs are set and the top is lightly golden.

Step 7: Cool and serve

Let the casserole rest for 5–10 minutes before slicing. Garnish with fresh parsley or dill, and serve warm.
