Ingredients

Scale

10 oz frozen spinach (thawed and drained)

1 cup crumbled feta cheese

5 large eggs

1 small onion, finely chopped

2 cloves garlic, minced

1 tablespoon olive oil

1/2 cup milk or half-and-half

1/2 teaspoon salt

1/4 teaspoon black pepper

1/8 teaspoon nutmeg (optional)

2 tablespoons chopped fresh herbs (like dill or parsley, optional)


Instructions

1. If using frozen spinach, thaw it completely and squeeze out as much moisture as possible. If using fresh spinach, chop and sauté until wilted, then let it cool.

2. Heat olive oil in a skillet over medium heat. Add chopped onion and sauté for about 5–6 minutes until translucent. Add minced garlic and cook for another 30 seconds. Let cool slightly.

3. In a large bowl, whisk together eggs and milk (or half-and-half).

4. Add the spinach, sautéed onion and garlic, crumbled feta, nutmeg, salt, pepper, and optional herbs to the egg mixture. Stir until everything is well combined.

5. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish.

6. Pour the mixture into the dish and smooth the top.

7. Bake for 35–40 minutes, or until the top is golden and the center is set. A knife inserted should come out clean.

8. Let it rest for 5–10 minutes before slicing and serving.

Notes

Always drain spinach thoroughly to avoid a watery casserole.

Let the casserole rest after baking so it sets up and slices neatly.

For richer flavor, use block feta instead of pre-crumbled.
