A Note on the Crust
This recipe includes a homemade pastry crust because, in my opinion, the process is therapeutic and the result is vastly superior to store-bought. However, if you are short on time or simply don’t want the fuss, a high-quality, refrigerated pie crust (the kind you roll out yourself) works perfectly as a time-saving alternative. Just unroll, fit into your pan, and proceed with the recipe.
Ingredients
For the Homemade Pie Crust (Optional but Recommended):
-
1 ¼ cups (155g) all-purpose flour
-
½ teaspoon salt
-
½ cup (115g) unsalted butter, very cold and cut into small cubes
-
3-4 tablespoons ice water
For the Quiche Filling:
-
1 tablespoon olive oil
-
1 medium yellow onion, finely chopped
-
2 cloves garlic, minced
-
10 ounces (280g) fresh spinach (or 1 package of frozen chopped spinach, thawed and squeezed very dry)
-
4 large eggs
-
1 ½ cups (360ml) heavy cream (or a mix of half-and-half and milk for a lighter version)
-
½ teaspoon salt
-
¼ teaspoon freshly ground black pepper
-
⅛ teaspoon ground nutmeg (freshly grated is best)
-
1 ½ cups (170g) shredded cheese (a blend of Gruyère and sharp cheddar is fantastic, but Swiss or a simple cheddar works well too)

-
Flavor Intensity:

Overall Aroma: Inviting and homey, with a distinct nutty note from the cheese and nutmeg.

Instructions
Step 1: Make the Crust (If Using Homemade)
-
In a food processor, pulse the flour and salt together.
-
Add the cold, cubed butter and pulse until the mixture resembles coarse crumbs, with some pea-sized pieces of butter remaining.
-
While pulsing, slowly add the ice water, one tablespoon at a time, until the dough just begins to clump together. Do not over-process.
-
Turn the dough out onto a lightly floured surface. Gently bring it together with your hands to form a disc. Wrap it in plastic wrap and refrigerate for at least 30 minutes. This resting period is crucial for preventing a tough crust.
Step 2: Pre-bake the Crust (Blind Bake)
-
Preheat your oven to 375°F (190°C).
-
On a floured surface, roll the chilled dough into a circle about 12 inches in diameter.
-
Gently fit the dough into a 9-inch tart pan with a removable bottom or a standard 9-inch pie dish. Press it firmly into the flutes and trim any excess overhang.
-
Prick the bottom of the crust all over with a fork. This prevents it from puffing up.
-
Line the inside of the crust with parchment paper and fill it with pie weights, dried beans, or rice.
-
Bake for 15 minutes. Remove the parchment and weights, and bake for another 5-7 minutes until the bottom is just starting to look dry and slightly golden. Remove from the oven and set aside. Reduce the oven temperature to 350°F (175°C).
Step 3: Prepare the Filling
-
While the crust is baking, heat the olive oil in a large skillet or Dutch oven over medium heat. Add the chopped onion and cook for 5-7 minutes, stirring occasionally, until softened and translucent.
-
Add the minced garlic and cook for one minute until fragrant.
-
Add the fresh spinach to the pan in handfuls. It will look like a mountain at first but will wilt down significantly. Cook until all the spinach is wilted, about 3-4 minutes.
-
Transfer the spinach mixture to a fine-mesh strainer or a clean kitchen towel. Press firmly with a spatula or squeeze the towel to remove as much excess liquid as possible. This step is non-negotiable; excess water will make your quiche soggy.
-
In a large mixing bowl, whisk together the eggs, heavy cream, salt, pepper, and nutmeg until smooth and well combined.
-
Stir the squeezed, cooked spinach and onions into the egg mixture.
-
Add the shredded cheese and fold everything together until just combined.
Step 4: Assemble and Bake
-
Pour the spinach and cheese filling into your pre-baked pie crust.
-
Transfer the quiche to the oven (on the middle rack) and bake at 350°F (175°C) for 40-45 minutes.
-
The quiche is done when the center is just set but still has a slight jiggle when you gently shake the pan. The top should be golden brown and slightly puffed.
-
If the edges of the crust are browning too quickly, you can cover them with a pie shield or strips of aluminum foil.
Step 5: Rest and Serve
-
This is the most important step: Let the quiche cool on a wire rack for at least 15-20 minutes. This allows the custard to set fully, making it easier to slice.
-
Serve warm or at room temperature. It is equally delicious either way. This quiche is a complete meal on its own but pairs beautifully with a simple green salad dressed with a lemon vinaigrette.
The Final Touch
This Spinach Quiche is more than just a recipe; it’s a canvas. Feel free to add crispy, crumbled bacon, sautéed mushrooms, or swap the spinach for kale or Swiss chard. The key to success is to ensure your greens are well-drained and your filling is seasoned with a generous hand.
Storage and Leftovers
This quiche stores beautifully. Keep it covered in the refrigerator for up to 4 days. It can be enjoyed cold, at room temperature, or gently reheated in a 300°F (150°C) oven until warmed through. I don’t recommend freezing it, as the texture of the custard can become watery upon thawing.
