A hearty vegetarian spinach feta quiche recipe that comes with a homemade quiche crust and the most delicious vegetarian filling!

This flaky, creamy, and cheesy vegetarian quiche is best served warm out of the oven! It makes for outstanding finger food at any party, savory brunch, or served as a weeknight family dinner alongside this green salad or Greek salad.

Spinach and feta harmonize very well together and do taste incredibly delicious served in a homemade quiche crust. I love to add one seeded red chili for a nice flavor, opt-in for a mild chili, or omit it altogether if you don’t like spicy food.

The spinach provides a good portion of vitamins and iron. Feta cheese adds some protein and makes for a salty, cheesy, and creamy finish!

The last component is the typical French quiche filling made with heavy cream and eggs, which ensures even more flavor! Vegetarian quiche couldn’t be more perfect! 

What to love more about this spinach quiche recipe is that you can prepare and bake it in advance – once your guests arrive, reheat it for a few minutes in the oven, and it tastes as if freshly baked!

Homemade Quiche Crust

Quiche should always be prepared with a homemade crust – just my two cents! Why? Homemade crust tastes better than any store-bought version – buttery, crispy, flaky!

Plus, it’s not super complicated nor time-consuming. You can even prepare the crust one day in advance if stored in the refrigerator = even less stress when baking!

I won’t judge if you are lazy or just not that much into baking but still want to serve a hearty meal for your family! Go for the store-bought pie crust in this case! 😉

Recipe FAQ & Tips

How long does it stay fresh? Leftovers can be stored for up to 3-4 days in the refrigerator. Store it in an airtight container, or wrap the cold quiche pan with plastic wrap/aluminum foil (easiest to reheat).

How do I reheat quiche? Reheat for 15-20 minutes in the preheated oven at 390°F (200°C).

Gluten-Free? Prepare the dough with gluten-free flour or use a store-bought gluten-free pie crust.

Looking for a dairy-free quiche recipe? Go for plant-based butter, dairy-free heavy cream, and a dairy-free cheese alternative (make sure it’s one that’s melting). → I usually bake my quiche with plant-based butter & heavy cream but opt-in for regular Feta cheese. 

Egg Replacement: The egg for the quiche crust can be replaced with 3-5 tablespoons of cold water – although the crust won’t turn out as crispy as when using an egg. Unfortunately, you can’t replace the eggs in the quiche filling as they are needed for the texture!
