Ingredients
- 1 tablespoon olive oil
- 1 small yellow onion, finely diced
- 1 cup fresh spinach, chopped
- 4 large eggs
- ½ cup whole milk (or half-and-half for a richer texture)
- ½ cup crumbled feta cheese
- Salt and freshly ground black pepper, to taste
- Butter or cooking spray, for greasing
Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or baking dish with butter or nonstick spray to ensure easy release after baking.
2. Sauté the Vegetables
In a medium skillet, heat the olive oil over medium heat. Add the diced onion and cook for 4 to 5 minutes, stirring occasionally, until the onion becomes soft and translucent. Add the chopped spinach and cook for an additional 2 to 3 minutes, just until wilted. Remove from heat and set aside to cool slightly.
3. Make the Egg Mixture
In a medium mixing bowl, whisk together the eggs and milk until fully combined and slightly frothy. Season with salt and black pepper to taste.
4. Combine Ingredients
Stir the sautéed spinach and onion mixture into the eggs. Add the crumbled feta cheese and mix gently to combine. Pour the mixture into the prepared pie dish, smoothing it into an even layer.
5. Bake the Quiche
Place the dish in the preheated oven and bake for 30 to 35 minutes, or until the center is fully set and the top is lightly golden. A toothpick or knife inserted in the center should come out clean.
6. Cool and Serve
Remove the quiche from the oven and let it cool for at least 5 to 10 minutes before slicing. This resting time allows the custard to firm up, making it easier to slice cleanly. Serve warm, at room temperature, or chilled straight from the refrigerator.
Serving Suggestions
- Pair it with a fresh garden salad or roasted potatoes for a complete meal.
- Serve with fruit and a slice of toast for a well-rounded breakfast or brunch.
- Add a dollop of Greek yogurt or a spoonful of tomato relish on top for extra flavor.
Make It Your Own
- Add Protein: Include chopped cooked bacon, diced ham, or sautéed mushrooms for a heartier version.
- Try Different Greens: Substitute spinach with kale, arugula, or Swiss chard for variety.
- Switch the Cheese: While feta adds a salty tang, goat cheese, shredded mozzarella, or parmesan are delicious alternatives.
Storage & Reheating Tips
This quiche stores well in the refrigerator for up to 4 days. Cover tightly or transfer to an airtight container. To reheat, warm slices in the microwave for 30–60 seconds, or bake in a 325°F oven until heated through.
It can also be made ahead and frozen. Cool completely, wrap tightly in plastic and foil, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
