Ingredients
- 2 cups fresh spinach, chopped (or 250 g frozen spinach, thawed and squeezed dry)
- 200 g feta cheese, crumbled
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 2 large eggs
- ½ cup milk (120 ml)
- ½ cup olive oil (120 ml)
- 1 cup all-purpose flour (120 g)
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ teaspoon ground black pepper
- ½ teaspoon dried oregano or dill
- Optional: ¼ cup grated mozzarella or Parmesan for extra cheesiness
Instructions
- Step 1: Preheat your oven to 180°C (350°F) and lightly grease or line a square baking dish with parchment paper.
- Step 2: Heat a tablespoon of olive oil in a skillet over medium heat. Sauté the onion and garlic until soft and fragrant. Add the spinach and cook until wilted if fresh, or until most moisture evaporates if using frozen. Remove from heat and let the mixture cool slightly.
- Step 3: In a large mixing bowl, whisk together the eggs, milk, and olive oil until smooth.
- Step 4: Stir in the flour, baking powder, salt, black pepper, and oregano until you have a thick but pourable batter.
- Step 5: Fold the cooled spinach mixture and crumbled feta cheese into the batter. Add the grated mozzarella or Parmesan if using, and mix gently to combine.
- Step 6: Pour the batter evenly into the prepared baking dish and smooth the top with a spatula.
- Step 7: Bake for 35 to 40 minutes, or until the top is golden and the center is set when gently shaken.
- Step 8: Let the bake cool for at least 10 minutes before cutting into squares. Serve warm, at room temperature, or chilled.

Main Ingredients
- 2 cups fresh spinach, chopped (or 250 g frozen spinach, thawed and squeezed dry)
- 200 g feta cheese, crumbled
- 1 small onion, finely chopped
- 2 garlic cloves, minced
- 2 large eggs
- ½ cup milk (120 ml)

- 1 cup all-purpose flour (120 g)
- 1 teaspoon baking powder
- ½ teaspoon salt
- ½ teaspoon ground black pepper
- ½ teaspoon dried oregano or dill
- Optional: ¼ cup grated mozzarella or Parmesan for extra cheesiness
Instructions
- Preheat the oven: Preheat your oven to 180°C (350°F) and lightly grease or line a square baking dish with parchment paper to prevent sticking.
- Sauté aromatics and spinach: Heat a tablespoon of olive oil in a skillet over medium heat and sauté the finely chopped onion and minced garlic until they become soft and fragrant. Add the fresh spinach and cook until wilted, or if using frozen spinach, cook until most of the moisture has evaporated. Remove from heat and allow the mixture to cool slightly.
- Prepare the batter: In a large mixing bowl, whisk together the eggs, milk, and olive oil until the mixture is smooth and combined. Stir in the flour, baking powder, salt, black pepper, and dried oregano or dill, mixing until you achieve a thick but pourable batter.
- Combine ingredients: Fold in the cooled spinach and onion mixture along with the crumbled feta cheese. If using, add the grated mozzarella or Parmesan cheese at this stage and gently mix to distribute evenly.
- Transfer and bake: Pour the batter evenly into the prepared baking dish and smooth the surface with a spatula. Place in the preheated oven and bake for 35 to 40 minutes or until the top is golden and the center is set.
- Cool and serve: Remove the bake from the oven and let it cool in the dish for at least 10 minutes before cutting into squares. Serve warm, at room temperature, or chilled depending on your preference.
Notes
- For best texture, ensure frozen spinach is thoroughly squeezed dry to remove excess moisture.
- You can substitute the milk with a dairy-free alternative if desired, but it may slightly affect the texture.
- Adding mozzarella or Parmesan enhances cheesiness but is optional.
- This dish can be stored in the refrigerator for up to 3 days and served cold or reheated.
