Ingredients for spinach and egg pie

Sixteen simple ingredients create a restaurant-quality pie with crispy herb crust and velvety egg filling.

The spinach is the foundation—baby spinach wilts faster and holds its vibrant color better than mature leaves. Costco or Trader Joe's often carry pre-washed baby spinach in larger quantities, which saves time. For the eggs, room temperature is key—they'll blend more smoothly into the custard. The Gruyère cheese, if using, should be freshly shredded (pre-shredded gets gummy when baked). Fresh herbs like chives and parsley make all the difference—store them in a damp paper towel in the fridge to keep them bright for the recipe.

No fresh chives or parsley? Dried herbs at half the amount work in a pinch, but fresh gives that bright, fresh flavor. Substitute milk with heavy cream for extra richness, or use almond milk for a lighter option. The olive oil can be swapped for butter if preferred, but olive oil adds a subtle fruity note. For the crust, if you don't have chives, extra parsley or basil will work. The sugar balances the tanginess of the lemon juice—reduce to 1/2 tbsp if you prefer less sweetness. Diamond Crystal salt measures differently than other brands—use the included spoon if available.

The crust mixture should be cold when assembling—chill it for 20 minutes before pressing into the pan. Store any leftovers in an airtight container for 3-4 days in the fridge, or freeze for up to 2 months. To reheat, cover with foil and warm at 350°F for 15 minutes. The pie reheats beautifully, making it perfect for meal prep. For best results, assemble the pie just before baking—don't prep ahead as the filling can get watery.

Step-by-step instructions for spinach and egg pie

Here's how to craft a perfect savory pie with a delicate herb crust and velvety custard filling.

Heat a large skillet over medium heat and add the 2 tablespoons extra-virgin olive oil. Once shimmering, add the 10 ounces fresh spinach (stems removed) and cook for 3-4 minutes until just wilted. The spinach should collapse into a vibrant green pile—don't overcook or it'll turn bitter.

Remove from heat and transfer the spinach to a mixing bowl. Add the 1 tablespoon lemon juice and 1 tablespoon granulated sugar, tossing gently to brighten the flavor. Let it cool completely before using in the filling—warm spinach releases too much moisture and can make the custard watery.

In a food processor, combine the 1.5 cups all-purpose flour, 0.5 cup cold unsalted butter (cut into cubes), 1.5 teaspoons kosher salt, and 0.5 teaspoon black pepper. Pulse until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. This texture is crucial for a flaky crust.

Add the 3 minced garlic cloves, 0.25 cup chopped parsley, and 0.25 cup chopped chives to the processor. Pulse just until the herbs are evenly distributed throughout the flour mixture. The herbs should be finely chopped but not completely pulverized—you should still see visible flecks. Transfer to a bowl and set aside.

In a separate large bowl, whisk together the 6 whole eggs and 1.5 cups whole milk until no streaks remain. The mixture should be completely smooth and uniform in color. Gradually whisk in the cooled spinach mixture until fully combined—this ensures even distribution of greens throughout the custard.

For the optional richness, fold in the 0.5 cup shredded Gruyère cheese using a spatula, being careful not to overmix. The cheese should melt smoothly into the custard mixture, creating pockets of flavor that will melt beautifully in the oven. Taste and adjust seasoning if needed, adding more salt or pepper as necessary.

Preheat your oven to 375°F. Grease a 9-inch pie dish thoroughly with butter or oil. Sprinkle about half of the herb crust mixture into the bottom of the dish, pressing it gently and evenly with your fingers to create an even layer. This forms the base that will support the custard filling.

Pour the egg custard mixture evenly over the crust layer, spreading it out to the edges. Sprinkle the remaining herb crust mixture evenly over the top, pressing down lightly to create a textured surface. Bake for 40-45 minutes until the top is golden brown and the center is just set—it should still have a slight wobble when gently shaken.

Remove the pie from the oven and let it rest for 10 minutes before slicing. This resting period allows the custard to fully set and prevents it from running when you cut into it. The crust should be golden brown with crisp edges, and the filling should be silky smooth with just a slight custardy texture.

Slice into wedges and serve immediately while still warm. The pie should have a delicate balance of flavors—savory spinach, herbed crust, and rich custard—with each bite offering a perfect combination of textures. For best results, serve with a simple arugula salad or crusty bread to complement the rich filling.
