Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- 1 cup fresh spinach, chopped
- 1 small onion, chopped
- 1 cup feta cheese, crumbled
- 4 large eggs
- 1 cup milk
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 1 tablespoon olive oil
Directions
1. Preheat the Oven
Preheat your oven to 350°F (175°C) and lightly grease a pie dish or quiche dish to ensure the quiche doesn’t stick.
2. Sauté the Vegetables
In a skillet, heat olive oil over medium heat. Add the chopped onion and sauté until it becomes translucent and soft, about 5-7 minutes. Then, add the chopped spinach and cook for another 2-3 minutes until it wilts. Set the mixture aside to cool slightly.
3. Prepare the Egg Mixture
In a mixing bowl, whisk together the eggs, milk, salt, pepper, and nutmeg until well combined.
4. Combine the Ingredients
Stir the sautéed spinach and onion mixture into the egg mixture. Then, fold in the crumbled feta cheese and mix until evenly distributed.
5. Bake the Quiche
Pour the mixture into the prepared pie dish. Smooth the top with a spatula to make sure it’s evenly distributed. Bake for 30-35 minutes, or until the quiche is set and lightly golden on top. You can check if it’s done by inserting a toothpick into the center—it should come out clean.
6. Let it Cool and Serve
Allow the quiche to cool for a few minutes before slicing. Serve warm or at room temperature.
