Ingredients

Scale

1 tbsp olive oil
1 small onion, chopped
2 cups fresh spinach, chopped (or 1 ½ cups frozen spinach, thawed and drained)
4 large eggs
1 cup milk (or plant-based milk)
1 cup crumbled feta cheese
½ cup shredded mozzarella cheese
½ tsp dried basil
Salt and pepper, to taste
1 tbsp fresh parsley (optional, for garnish)

Instructions

Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or baking dish.
Heat olive oil in a skillet over medium heat. Add chopped onion and sauté for 3-4 minutes until soft.
Stir in the spinach and cook for 1-2 minutes, just until wilted. Remove from heat and let cool slightly.
In a mixing bowl, whisk together the eggs, milk, dried basil, salt, and pepper. Stir in the crumbled feta and shredded mozzarella.
Spread the sautéed onions and spinach evenly in the pie dish. Pour the egg mixture over the top, ensuring even distribution.
Bake for 35-40 minutes, or until the quiche is set and lightly golden on top. A knife inserted in the center should come out clean.
Let the quiche cool for 5-10 minutes before slicing. Garnish with fresh parsley if desired and serve warm.

Notes

If using frozen spinach, make sure to squeeze out excess moisture to prevent a watery quiche.
Swap feta for goat cheese, ricotta, or sharp cheddar for a different flavor twist.
Make it dairy-free by using plant-based milk and dairy-free cheese.
Store leftovers in the fridge for up to 4 days or freeze slices for up to 3 months.
