What Is Spinach Quiche?
Spinach quiche is a French-inspired savory pie made with a pastry crust and a filling of eggs, cream, spinach, and cheese.
It’s part of the quiche family, which originated in the Lorraine region of France. The original quiche Lorraine was made with just eggs, cream, and bacon.
Over the years, cooks started adding all sorts of vegetables and cheeses to create their own versions. And honestly? Spinach might be the best addition of them all.
The spinach wilts down into the custard and adds a subtle earthy flavor that pairs perfectly with the rich, creamy egg mixture.
It’s basically the dish that proves vegetables can be absolutely delicious.

Ingredients You’ll Need
Here’s everything you need to make the best spinach quiche:
For the Crust:
Store-bought pie crust – This is the easiest route and it works perfectly. Of course, you can make your own if you prefer.
For the Filling:
Fresh spinach – You’ll need about 10 ounces (6 cups packed). It cooks way down, so don’t worry if it looks like a mountain of greens.
Butter – For sauteing the onion and garlic. Just a tablespoon does the trick.
Yellow onion – Adds a sweet, aromatic base to the filling.
Garlic – Two cloves is the sweet spot. It adds flavor without being overpowering.
Eggs – Four large eggs create the custard base. They set the filling and give it that classic quiche texture.
Heavy cream and whole milk – This combo gives you a custard that’s rich but not too heavy. The milk lightens things up just enough.
Gruyere cheese – The real star here. Gruyere has a nutty, slightly sweet flavor that melts like a dream. Swiss cheese works great as a substitute.
Salt, pepper, and nutmeg – Simple seasonings that make all the difference. The nutmeg is the secret ingredient that ties everything together.
How to Make Classic Spinach Quiche
This recipe is easier than you think. Here’s how to put it all together:
Step 1: Blind bake the crust. Preheat your oven to 375 degrees F. Press the pie crust into a 9-inch dish and prick the bottom with a fork. Line it with parchment paper and pie weights, then bake for 10 minutes. Remove the weights and bake 5 more minutes until lightly golden.
This step is crucial for preventing a soggy bottom. Don’t skip it!
Step 2: Cook the spinach filling. Melt butter in a large skillet and cook the diced onion until soft, about 3-4 minutes. Add the garlic and cook for 30 seconds until fragrant.
Toss in the spinach and cook until it’s completely wilted. Then transfer it to a colander and squeeze out every last drop of moisture. This is the biggest key to a perfect quiche.
Step 3: Make the custard. Whisk together the eggs, heavy cream, milk, salt, pepper, and nutmeg in a large bowl. You want it completely smooth.
Step 4: Assemble. Spread the spinach mixture over the crust. Top with shredded Gruyere. Then pour the custard over everything.
Step 5: Bake. Pop it in the oven for 40-45 minutes. The quiche is done when the center is set and the top is a beautiful golden color.
Let it cool for at least 10-15 minutes before slicing. I know it’s tempting, but this resting time helps the custard firm up so you get clean, beautiful slices.
Tips for the Perfect Quiche
Squeeze that spinach dry. Seriously, this is the number one tip. Excess moisture will make your quiche watery. Use a clean kitchen towel or paper towels and wring out every bit of liquid.
Don’t skip the blind bake. Par-baking the crust ensures it stays crisp and flaky even after the wet custard is added.
Use room temperature eggs. They blend more smoothly into the custard and help the quiche bake more evenly.
Don’t overbake. The center should still have a slight jiggle when you take it out of the oven. It will continue to set as it cools.
Let it rest. Give it at least 10-15 minutes before cutting. A freshly sliced quiche will be runny. A rested one will be perfectly creamy.
Variations to Try
Once you master this classic version, feel free to get creative with mix-ins!
Spinach and mushroom quiche: Add 8 ounces of sliced cremini mushrooms sauteed with the onion. The earthy mushrooms are incredible with the spinach.
Bacon spinach quiche: Crumble 6 strips of cooked bacon into the filling. Because everything is better with bacon.
Sun-dried tomato and spinach: Add 1/3 cup chopped sun-dried tomatoes. The tangy sweetness pairs beautifully with the Gruyere.
Feta and spinach quiche: Swap the Gruyere for crumbled feta cheese for a Greek-inspired twist.
Ham and spinach quiche: Add 1 cup of diced ham for a heartier version that’s perfect for brunch.
Storage and Reheating
Refrigerator: Store leftover quiche covered in the fridge for up to 4 days. It tastes great cold or reheated.
Freezer: Wrap the quiche tightly in plastic wrap and then aluminum foil. It freezes well for up to 3 months.
To reheat: Place individual slices in a 325 degree F oven for 15-20 minutes until warmed through. You can also microwave for 1-2 minutes, but the oven gives you a much better crust.
Pro tip: Slice the quiche before freezing so you can grab individual portions whenever you need a quick meal.
